Hermes Web UI

Hermes Agent is a sophisticated autonomous agent that lives on your server, accessed via a terminal or messaging apps, that remembers what it learns and gets more capable the longer it runs.

Hermes WebUI is a lightweight, dark-themed web app interface in your browser for Hermes Agent. Full parity with the CLI experience - everything you can do from a terminal, you can do from this UI. No build step, no framework, no bundler. Just Python and vanilla JS.

Layout: three-panel. Left sidebar for sessions and navigation, center for chat, right for workspace file browsing. Model, profile, and workspace controls live in the composer footer — always visible while composing. A circular context ring shows token usage at a glance. All settings and session tools are in the Hermes Control Center (launcher at the sidebar bottom).

_{Light mode with full profile support}

_{Customize your settings, configure a password}

_{Workspace file browser with inline preview}

_{Session projects, tags, and tool call cards}

This gives you nearly 1:1 parity with Hermes CLI from a convenient web UI which you can access securely through an SSH tunnel from your Hermes setup. Single command to start this up, and a single command to SSH tunnel for access on your computer. Every single part of the web UI uses your existing Hermes agent and existing models, without requiring any additional setup.

Why Hermes

Most AI tools reset every session. They don't know who you are, what you worked on, or what conventions your project follows. You re-explain yourself every time.

Hermes retains context across sessions, runs scheduled jobs while you're offline, and gets smarter about your environment the longer it runs. It uses your existing Hermes agent setup, your existing models, and requires no additional configuration to start.

What makes it different from other agentic tools:

Persistent memory — user profile, agent notes, and a skills system that saves reusable procedures; Hermes learns your environment and does not have to relearn it
Self-hosted scheduling — cron jobs that fire while you're offline and deliver results to Telegram, Discord, Slack, Signal, email, and more
10+ messaging platforms — the same agent available in the terminal is reachable from your phone
Self-improving skills — Hermes writes and saves its own skills automatically from experience; no marketplace to browse, no plugins to install
Provider-agnostic — OpenAI, Anthropic, Google, DeepSeek, OpenRouter, and more
Orchestrates other agents — can spawn Claude Code or Codex for heavy coding tasks and bring the results back into its own memory
Self-hosted — your conversations, your memory, your hardware

vs. the field (landscape is actively shifting — see docs/why-hermes.md for the full breakdown):

	OpenClaw	Claude Code	Codex CLI	OpenCode	Hermes
Persistent memory (auto)	Yes	Partial†	Partial	Partial	Yes
Scheduled jobs (self-hosted)	Yes	No‡	No	No	Yes
Messaging app access	Yes (15+ platforms)	Partial (Telegram/Discord preview)	No	No	Yes (10+)
Web UI (self-hosted)	Dashboard only	No	No	Yes	Yes
Self-improving skills	Partial	No	No	No	Yes
Python / ML ecosystem	No (Node.js)	No	No	No	Yes
Provider-agnostic	Yes	No (Claude only)	Yes	Yes	Yes
Open source	Yes (MIT)	No	Yes	Yes	Yes

† Claude Code has CLAUDE.md / MEMORY.md project context and rolling auto-memory, but not full automatic cross-session recall
‡ Claude Code has cloud-managed scheduling (Anthropic infrastructure) and session-scoped /loop; no self-hosted cron

The closest competitor is OpenClaw — both are always-on, self-hosted, open-source agents with memory, cron, and messaging. The key differences: Hermes writes and saves its own skills automatically as a core behavior (OpenClaw's skill system centers on a community marketplace); Hermes is more stable across updates (OpenClaw has documented release regressions and ClawHub has had security incidents involving malicious skills); and Hermes runs natively in the Python ecosystem. See docs/why-hermes.md for the full side-by-side.

Quick start

Run the repo bootstrap:

git clone https://github.com/nesquena/hermes-webui.git hermes-webui
cd hermes-webui
python3 bootstrap.py

Or keep using the shell launcher:

./start.sh

For self-hosted VM or homelab installs, ctl.sh wraps the common daemon lifecycle commands without requiring fuser or pkill:

./ctl.sh start              # background daemon, PID at ~/.hermes/webui.pid
./ctl.sh status             # PID, uptime, bound host/port, log path, /health
./ctl.sh logs --lines 100   # tail ~/.hermes/webui.log
./ctl.sh restart
./ctl.sh stop

ctl.sh start runs the bootstrap in foreground/no-browser mode behind the daemon wrapper, writes logs to ~/.hermes/webui.log, and respects .env plus inline overrides such as HERMES_WEBUI_HOST=0.0.0.0 ./ctl.sh start.

Advanced: dynamic recall prefill & Gateway-backed chat

Two optional, self-hosted-deployment features — attaching dynamic session-recall prefill to browser turns (Joplin/Obsidian/Notion/llm-wiki routers), and routing browser chat through a running Hermes Gateway — are documented in docs/advanced-chat-setup.md. Most users need neither.

The bootstrap will:

Detect Hermes Agent and, if missing, attempt the official installer (curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash).
Find or create a Python environment with the WebUI dependencies.
Start the web server and wait for /health.
Open the browser unless you pass --no-browser.
Drop you into a first-run onboarding wizard inside the WebUI.

Native Windows is not supported for this bootstrap yet. Use Linux, macOS, or WSL2. For Windows / WSL auto-start at login, see docs/wsl-autostart.md.

A community-maintained native Windows setup is documented at @markwang2658/hermes-windows-native-guide (companion setup repo: @markwang2658/hermes-windows-native). Notes from the community report in #1952:

Memory: community-measured ~330 MB native vs ~1080 MB with WSL2+Docker (varies by configuration).
What works: chat, workspace browser, session management, all themes.
Known limitations: some POSIX-style file paths surface in the workspace browser; bash-assuming agent tools may not work natively.
Native Windows setup: install Python 3.11+, then from the hermes-agent root in PowerShell: python -m venv venv → pip install -r requirements.txt → pwsh .\start.ps1 (it auto-discovers venv\Scripts\python.exe).
WSL2 relationship: not a prerequisite — a WSL2-built venv (venv/bin/python, ELF) isn't invokable by native Windows Python, so use the native setup above. WSL2 stays useful as a parallel install if you want the full bootstrap.py + Linux runtime.

If provider setup is still incomplete after install, the onboarding wizard will point you to finish it with hermes model instead of trying to replicate the full CLI setup in-browser. For a step-by-step walkthrough of the wizard, provider choices, local model server Base URLs, and safe re-runs, see docs/onboarding.md. If an AI assistant is helping with install, reinstall, bootstrap, provider setup, or first-run support, have it read docs/onboarding-agent-checklist.md before running commands or inspecting logs.

Files slide-over panel from right edge
Touch targets minimum 44px on all interactive elements
Full-height chat/composer on phones without bottom-nav spacing
Desktop layout completely unchanged

Configuration & access

start.sh auto-detects almost everything; the subsections below cover the knobs for when it can't, and how to reach the UI remotely.

What start.sh discovers automatically

Thing	How it finds it
Hermes agent dir	`HERMES_WEBUI_AGENT_DIR` env, then `$HERMES_HOME/hermes-agent` (Windows default `%LOCALAPPDATA%\hermes\hermes-agent`, POSIX default `~/.hermes/hermes-agent`), then sibling `../hermes-agent`
Python executable	Agent venv first, then `.venv` in this repo, then system `python3`
State directory	`HERMES_WEBUI_STATE_DIR` env, then `$HERMES_HOME/webui` (Windows default `%LOCALAPPDATA%\hermes\webui`, POSIX default `~/.hermes/webui`)
Default workspace	`HERMES_WEBUI_DEFAULT_WORKSPACE` env, then `~/workspace`, then state dir
Port	`HERMES_WEBUI_PORT` env or first argument, default `8787`

If discovery finds everything, nothing else is required.

Overrides (only needed if auto-detection misses)

export HERMES_WEBUI_AGENT_DIR=/path/to/hermes-agent
export HERMES_WEBUI_PYTHON=/path/to/python
export HERMES_WEBUI_PORT=9000
export HERMES_WEBUI_AUTO_INSTALL=1  # enable auto-install of agent deps (disabled by default)
./start.sh

Or inline:

HERMES_WEBUI_AGENT_DIR=/custom/path ./start.sh 9000

Full list of environment variables:

Variable	Default	Description
`HERMES_WEBUI_AGENT_DIR`	auto-discovered	Path to the hermes-agent checkout
`HERMES_WEBUI_PYTHON`	auto-discovered	Python executable
`HERMES_WEBUI_HOST`	`127.0.0.1`	Bind address (`0.0.0.0` for all IPv4, `::` for all IPv6, `::1` for IPv6 loopback)
`HERMES_WEBUI_PORT`	`8787`	Port
`HERMES_WEBUI_STATE_DIR`	`$HERMES_HOME/webui` (Windows default `%LOCALAPPDATA%\hermes\webui`, POSIX default `~/.hermes/webui`)	Where sessions and state are stored
`HERMES_WEBUI_DEFAULT_WORKSPACE`	`~/workspace`	Default workspace
`HERMES_WEBUI_DEFAULT_MODEL`	(provider default)	Optional model override; leave unset to use the active Hermes provider default
`HERMES_WEBUI_PASSWORD`	(unset)	Set to enable password authentication
`HERMES_WEBUI_CSP_CONNECT_EXTRA`	(unset)	Optional space-separated `http(s)://` or `ws(s)://` origins to append to the report-only CSP `connect-src` directive for reverse-proxy or tunnel deployments
`HERMES_WEBUI_EXTENSION_DIR`	(unset)	Optional local directory served at `/extensions/`; must point to an existing directory before extension injection is enabled
`HERMES_WEBUI_EXTENSION_SCRIPT_URLS`	(unset)	Optional comma-separated same-origin script URLs to inject; see WebUI Extensions
`HERMES_WEBUI_EXTENSION_STYLESHEET_URLS`	(unset)	Optional comma-separated same-origin stylesheet URLs to inject; see WebUI Extensions
`HERMES_HOME`	Windows: `%LOCALAPPDATA%\hermes`; POSIX: `~/.hermes`	Base directory for Hermes state (affects all paths)
`HERMES_CONFIG_PATH`	`$HERMES_HOME/config.yaml`	Path to Hermes config file

Remote access (SSH tunnel, Tailscale, phone)

The server binds to 127.0.0.1 by default. To reach it from another machine use an SSH tunnel (ssh -N -L 8787:127.0.0.1:8787 user@host, which start.sh prints for you over SSH), or join your server and phone to a Tailscale network and browse to http://<server-tailscale-ip>:8787 with HERMES_WEBUI_HOST=0.0.0.0 + HERMES_WEBUI_PASSWORD set. Full walkthrough (incl. a community ARM64-Android field report): docs/remote-access.md.

Manual launch (without start.sh)

If you prefer to launch the server directly:

cd /path/to/hermes-agent          # or wherever sys.path can find Hermes modules
HERMES_WEBUI_PORT=8787 venv/bin/python /path/to/hermes-webui/server.py

Note: use the agent venv Python (or any Python environment that has the Hermes agent dependencies installed). System Python will be missing openai, httpx, and other required packages.

Health check:

curl http://127.0.0.1:8787/health

Docker

Pre-built images (amd64 + arm64) are published to GHCR on every release.

For a comprehensive setup guide covering all 3 compose files, common failure modes, and bind-mount migration, see docs/docker.md. The README covers the 5-minute happy path.

5-minute quickstart (single container)

The simplest setup: one WebUI container that runs the agent in-process.

git clone https://github.com/nesquena/hermes-webui
cd hermes-webui
cp .env.docker.example .env
# Edit .env if your host UID isn't 1000 (e.g. macOS where UIDs start at 501)
docker compose up -d
# Open http://localhost:8787

Run Compose as the user who owns your Hermes home. sudo docker compose up -d can make ${HOME} expand to the root user's home, so Docker mounts the wrong .hermes directory instead of your real ~/.hermes and the WebUI starts with config.yaml (not found, using defaults). Prefer adding your user to the Docker group and running docker compose up -d; if you must use sudo, set absolute paths first, for example HERMES_HOME=/home/you/.hermes HERMES_WORKSPACE=/home/you/workspace sudo -E docker compose up -d, then verify with docker compose config.

The container auto-detects your UID/GID from the mounted ~/.hermes volume so files written by the agent stay readable by you on the host.

To enable password protection (required if you expose the port outside 127.0.0.1):

echo "HERMES_WEBUI_PASSWORD=change-me-to-something-strong" >> .env
docker compose up -d --force-recreate

Manual `docker run` (no compose)

docker pull ghcr.io/nesquena/hermes-webui:latest
docker run -d \
  -e WANTED_UID=$(id -u) -e WANTED_GID=$(id -g) \
  -v ~/.hermes:/home/hermeswebui/.hermes \
  -e HERMES_WEBUI_STATE_DIR=/home/hermeswebui/.hermes/webui \
  -v ~/workspace:/workspace \
  -p 127.0.0.1:8787:8787 \
  ghcr.io/nesquena/hermes-webui:latest

Build locally

docker build -t hermes-webui .
docker run -d \
  -e WANTED_UID=$(id -u) -e WANTED_GID=$(id -g) \
  -v ~/.hermes:/home/hermeswebui/.hermes \
  -e HERMES_WEBUI_STATE_DIR=/home/hermeswebui/.hermes/webui \
  -v ~/workspace:/workspace \
  -p 127.0.0.1:8787:8787 \
  hermes-webui

Multi-container setups

If you want the agent and WebUI in separate containers (for isolation, or because you're already running an agent gateway elsewhere):

# Agent + WebUI
docker compose -f docker-compose.two-container.yml up -d

# Agent + Dashboard + WebUI
docker compose -f docker-compose.three-container.yml up -d

Both compose files use named Docker volumes by default, which solves the UID/GID problem by construction. If you need bind mounts to share an existing host directory, see docs/docker.md for the full migration recipe.

Known limitation (#681): in the two-container setup, tools triggered from the WebUI run in the WebUI container, not the agent container. If you need git/node/etc. on the WebUI's filesystem, either use the single-container setup, extend the WebUI Dockerfile, or use the community all-in-one image.

Source boundary note (#2453): the multi-container setup mounts hermes-agent-src read-only into the WebUI by default. This prevents WebUI-side source rewrites but is still an implementation-coupling bridge, not a stable Agent API boundary. See docs/rfcs/agent-source-boundary.md for the current source/API decoupling inventory.

Common failure modes

Symptom	Likely cause	Fix
`PermissionError` at startup	UID mismatch on bind mount	Set `UID=$(id -u)` in `.env`
`.env: permission denied` (#1389)	`fix_credential_permissions()` enforced 0600	Set `HERMES_SKIP_CHMOD=1` in `.env`
Workspace appears empty	UID mismatch on `/workspace` mount	Set `UID=$(id -u)` in `.env`
`git: command not found` in chat	Two-container architectural limit (#681)	Use single-container or extend Dockerfile
WebUI can't find agent source	`hermes-agent-src` volume misconfigured	Use the named volumes from compose files as-is
Podman shared `.hermes` fails	Podman 3.4 `keep-id` limitation	Use Podman 4+ or single-container
Host API at `localhost` fails from WebUI	Container `localhost` means the container, not your host (#3012)	Use `http://host.docker.internal:<port>` on Docker Desktop, or `http://host.containers.internal:<port>` on Podman
WebUI can't see `~/.hermes` after `sudo docker compose`	`${HOME}` expanded to the root user's home (#3006)	Run Compose as your user, or pass absolute `HERMES_HOME`/`HERMES_WORKSPACE` with `sudo -E`

For the deep dive on each of these, see docs/docker.md.

Note: By default, Docker Compose binds to 127.0.0.1 (localhost only). To expose on a network, change the port to "8787:8787" in docker-compose.yml and set HERMES_WEBUI_PASSWORD to enable authentication.

Running tests

Tests discover the repo and the Hermes agent dynamically -- no hardcoded paths.

cd hermes-webui
pytest tests/ -v --timeout=60

Or using the agent venv explicitly:

/path/to/hermes-agent/venv/bin/python -m pytest tests/ -v

Tests run against an isolated server with a separate state directory. Production data and real cron jobs are never touched. Current snapshot: ~7,150 tests collected across ~700 test files, run in CI on Python 3.11, 3.12, and 3.13 (3 parallel shards each).

Architecture

No build step, no framework, no bundler — a Python standard-library HTTP server and vanilla JS. The backend lives in api/, the frontend in static/.

pyproject.toml    Tooling config (ruff lint gate) — not a packaged distribution
Dockerfile        python:3.12-slim container image
docker-compose.yml  Compose with named volume and optional auth
.github/workflows/  CI: ruff + sharded pytest, browser smoke, Docker smoke,
                    multi-arch Docker build + GitHub Release on tag

State lives outside the repo at ~/.hermes/webui/ by default (sessions, workspaces, settings, projects, last_workspace). Override with HERMES_WEBUI_STATE_DIR. Full design notes and the endpoint catalog are in ARCHITECTURE.md.

@bergeouss — Provider management UI + Docker hardening (70 PRs, v0.48.0 → v0.51.46) Provider management UI for adding/editing custom providers from Settings, OAuth provider status detection (#1552), two-container Docker setup, profile isolation hardening (per-profile .env secrets), the bulk of what users see when they touch Settings → Providers, Reveal-in-Finder context menu (#1551), gateway status card (#1552), auto-assign session to active project filter (#1550), "What's new?" link in update banner (#1549), OpenRouter free-tier live fetch (#1548), credential pool 401 self-heal (#1553), inline provider chip + group model count in model picker (#1644).

@ai-ag2026 — Session recovery + audit infrastructure (67 PRs, v0.50.279 → v0.51.190) Autonomous-AI contributor (Hermes Agent-driven) focused on durability: state.db-backed sidecar reconciliation (#2041), orphan .json.bak recovery on startup (#2035), read-only session recovery audit endpoints (#2036, #2040), active run lifecycle in /health (#2039), crash-safe turn-journal RFC at docs/rfcs/turn-journal.md (#2042), append-only turn-journal helper (#2059), lifecycle events layer (#2062), Content-Security-Policy-Report-Only header (#2084), per-cron toast toggle (#2100), fork-session compression lineage isolation (#2014).

@dso2ng — Session lineage + diagnostics (25 PRs, v0.50.227 → v0.51.153) /api/session/lineage-report/<sid> endpoint for bounded session graph diagnostics (#2012), stale Mermaid render error cleanup (#1337), session_source="fork" continuation-chain isolation (#2063), lazy lineage-report fetch on sidebar badge expand (#2130), and a long tail of frontend reliability fixes around session loading.

@jasonjcwu — Composer + transcript polish (16 PRs, v0.50.227 → v0.51.132) Sidebar collapse via active-rail click (#2054, fuses #1884 + #1924), composer chip lightbox (#1758), title fixes for tool-heavy first turns, silent compress-status during session switch (#2185), concurrent-send loss fix (#2186), in-transcript steer message badges (#2187), and a string of frontend polish fixes.

@Jordan-SkyLF — Live streaming + UX polish (12 PRs, v0.50.18 → v0.51.66) Original sprint of workspace fallback resolution, live reasoning cards (#366, #367, #394–#397), then a recent burst: manual "Refresh usage" button on the Provider quota card (#2150), cancelled-turn status classification (#2151), Firefox sidebar scroll stabilization (#2200), early provisional session titles (#2202), target-aware "What's new?" update-banner links (#2207), and MCP tools overflow fix in Settings (#2210).

@aronprins — v0.50.0 UI overhaul (PR #242, plus 9 follow-ups) The biggest single contribution to the project: a complete UI redesign that moved model/profile/workspace controls into the composer footer, replaced the gear-icon settings panel with the Hermes Control Center (tabbed modal), removed the activity bar in favor of inline composer status, redesigned the session list with a ⋯ action dropdown, and added the workspace panel state machine. Plus chat transcript redesign (#587), sidebar declutter (#584), three-column layout refactor (#899), light/dark theme + accent skins (#627), and shared confirm()/prompt() dialog replacement (PR #251 extracted from #242).

@iRonin — Security hardening sprint (PRs #196–#204) Six consecutive, focused security PRs: session memory leak fix (expired token pruning), CSP + Permissions-Policy headers, 30-second slow-client connection timeout, optional HTTPS/TLS support via environment variables, upstream branch tracking fix for self-update, and CLI session support in the file-browser API. The kind of focused, high-quality security work that makes a self-hosted tool trustworthy.

@lucasrc — Auth-hardening trilogy (PRs #2191, #2192, #2193) Three coordinated security PRs that all landed in v0.51.57: thread-safe login rate limiter with PBKDF2 key separation, password-hash cache invalidation on Settings save, and the full 64-char HMAC-SHA256 session signature with a backwards-compatible migration bridge. The kind of cleanly-decomposed security work that's reviewable as three independent pieces.

@LumenYoung — Streaming hot-path correctness (8 PRs, v0.51.47 → v0.51.99) The original stale-stream writeback guard (#2136 — the bug class the next two releases extended), gateway-state alive-null classification (#2075), compression-banner anchor alignment (#2182), and context-progress ring auto-refresh on compression complete (#2188). Each PR opened a small surgical fix in one of the most fragile subsystems in the codebase.

@dobby-d-elf — Frontend reliability + motion polish (15 PRs, v0.51.38 → v0.51.161) Workspace fallback on deleted directories (#2138), iPhone PWA bottom-scroll fix (#2143), the new "Activity: X tools" composer footer shimmer animation (#2203), and follow-up animation tuning (#2212).

@JKJameson — Composer + session polish (10 PRs) Persistent composer draft per session (#1956), and a long tail of polish across the composer and session sidebar.

@gabogabucho — Spanish locale + onboarding wizard Full Spanish (es) locale covering all UI strings, plus the one-shot bootstrap onboarding wizard that guides new users through provider setup on first launch.

@deboste — Reverse-proxy auth + mobile responsive layout (PRs #3, #4, #5) Three of the very first community PRs: fixed EventSource/fetch to use URL origin for reverse-proxy setups, corrected model provider routing from config, and added mobile responsive layout with dvh viewport fix. Early foundation work.

@indigokarasu — Visual redesign proposal (PR #213) A CSS-only redesign of the full UI — proper design tokens, an icon rail sidebar replacing the emoji tab strip, consistent form cards, breadcrumb nav, and 7 built-in themes as custom properties. The PR didn't merge as-is but shaped the design language and theme architecture that shipped in v0.50.0.

@zenc-cp — Anti-hallucination guard for the ReAct loop (PR #133) A three-layer approach (ephemeral anti-hallucination prompt, live token filtering, session-history cleanup) that the streaming pipeline still uses.

@Hinotoi-agent — Profile + session security (PRs #351, #2048) Profile .env secret isolation fix (PR #351) preventing API key leakage between profiles, and session-import workspace validation (PR #2048) blocking a crafted-JSON file-read against /.

@Sanjays2402 — Endless-scroll + Start-jump race fix (PR #1949) A generation-token + mutex pair fixing the v0.51.30 race between endless-scroll prefetch and Start-jump's _ensureAllMessagesLoaded. The naive same-flag-check approach (proposed in #1942 and #1962) was a no-op for the post-await race — Sanjays2402's fix was the correct shape.

@fxd-jason — Real-time approval + clarify via SSE (PRs #1350, #1355) Replaced 1.5s HTTP polling with SSE long-connections for both approval and clarify, cutting latency from up to 1.5s to near-instant. Got all the correctness details right (atomic subscribe + snapshot, notify-inside-lock, head-of-queue payload, trailing event re-emission).

@happy5318 — Custom provider model dedup (PR #1947) Fixed the same model from different named custom providers being silently deduplicated in the picker, with Opus catching a race in the original tests that needed augmentation.

@NocGeek — Streaming scroll + manual cron output persistence (7 PRs) Streaming scroll viewport stability when tool/queue cards insert (#1360), manual cron-run output and metadata persistence (#1372, split from held #1352).

@DavidSchuchert — German translation (PR #190) Complete German locale (de) covering all UI strings, settings labels, commands, and system messages — and stress-tested the i18n system, exposing several elements that weren't yet translatable and getting them fixed as part of the same PR.

@Bobby9228 — Mobile Profiles button (PR #265) Added the Profiles entry to the mobile navigation flow, making profile switching reachable on phones.

@kevin-ho — OLED theme (PR #168) The 7th built-in theme: pure black backgrounds with warm accents tuned to reduce burn-in risk.

@andrewy-wizard — Chinese localization (PR #177) Initial Simplified Chinese (zh) locale. One of the first non-English locales.

@DelightRun — session_search fix for WebUI sessions (PR #356) Tracked down the missing SessionDB injection in the streaming path that was silently breaking the tool for every WebUI session.

@lawrencel1ng — Bandit security fixes (PR #354) Systematic bandit-scan fixes: URL scheme validation before urlopen, MD5 usedforsecurity=False, and 40+ bare except: pass blocks replaced with proper logging.

@shaoxianbilly — Unicode filename downloads (PR #378) Proper Content-Disposition with RFC 5987 filename*=UTF-8''... encoding so non-ASCII filenames download without crashing.

@lx3133584 — CSRF fix for reverse proxy (PR #360) A real-world blocker for anyone hosting behind Nginx Proxy Manager or similar on a port other than 80/443.

@betamod — Security audit (PR #171) A comprehensive CSRF / SSRF / XSS / env-race-condition audit that shipped in v0.39.0.

@TaraTheStar — Bot name + thinking blocks + login refactor (PRs #132, #176, #181) Configurable assistant display name, thinking/reasoning block display, and a login page refactor.
