# Hermes Web UI
[Hermes Agent](https://hermes-agent.nousresearch.com/) 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](https://hermes-agent.nousresearch.com/).
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).

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 [HERMES.md](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 [HERMES.md](HERMES.md) for the full side-by-side.

## Quick start
Run the repo bootstrap:
```bash
git clone https://github.com/nesquena/hermes-webui.git hermes-webui
cd hermes-webui
python3 bootstrap.py
```
Or keep using the shell launcher:
```bash
./start.sh
```
For self-hosted VM or homelab installs, `ctl.sh` wraps the common daemon lifecycle commands without requiring `fuser` or `pkill`:
```bash
./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`.
The bootstrap will:
1. Detect Hermes Agent and, if missing, attempt the official installer (`curl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bash`).
2. Find or create a Python environment with the WebUI dependencies.
3. Start the web server and wait for `/health`.
4. Open the browser unless you pass `--no-browser`.
5. 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`](docs/wsl-autostart.md).
> A community-maintained native Windows guide is tracked in [#1952](https://github.com/nesquena/hermes-webui/issues/1952).
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`](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`](docs/onboarding-agent-checklist.md) before running commands or inspecting logs.
---
## 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`](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.
```bash
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
```
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`):
```bash
echo "HERMES_WEBUI_PASSWORD=change-me-to-something-strong" >> .env
docker compose up -d --force-recreate
```
### Manual `docker run` (no compose)
```bash
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
```bash
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):
```bash
# 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`](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](https://github.com/sunnysktsang/hermes-suite).
### 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 |
For the deep dive on each of these, see [`docs/docker.md`](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.

## What start.sh discovers automatically
| Thing | How it finds it |
|---|---|
| Hermes agent dir | `HERMES_WEBUI_AGENT_DIR` env, then `~/.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/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)
```bash
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:
```bash
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/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_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](docs/EXTENSIONS.md) |
| `HERMES_WEBUI_EXTENSION_STYLESHEET_URLS` | *(unset)* | Optional comma-separated same-origin stylesheet URLs to inject; see [WebUI Extensions](docs/EXTENSIONS.md) |
| `HERMES_HOME` | `~/.hermes` | Base directory for Hermes state (affects all paths) |
| `HERMES_CONFIG_PATH` | `~/.hermes/config.yaml` | Path to Hermes config file |
---
## Accessing from a remote machine
The server binds to `127.0.0.1` by default (loopback only). If you are running
Hermes on a VPS or remote server, use an SSH tunnel from your local machine:
```bash
ssh -N -L <local-port>:127.0.0.1:<remote-port> <user>@<server-host>
```
Example:
```bash
ssh -N -L 8787:127.0.0.1:8787 user@your.server.com
```
Then open `http://localhost:8787` in your local browser.
`start.sh` will print this command for you automatically when it detects you
are running over SSH.
---
## Accessing on your phone with Tailscale
[Tailscale](https://tailscale.com) is a zero-config mesh VPN built on
WireGuard. Install it on your server and your phone, and they join the same
private network -- no port forwarding, no SSH tunnels, no public exposure.
The Hermes Web UI is fully responsive with a mobile-optimized layout
(hamburger sidebar, sidebar top tabs in the drawer, touch-friendly controls),
so it works well as a daily-driver agent interface from your phone.
**Setup:**
1. Install [Tailscale](https://tailscale.com/download) on your server and
your iPhone/Android.
2. Start the WebUI listening on all interfaces with password auth enabled:
```bash
HERMES_WEBUI_HOST=0.0.0.0 HERMES_WEBUI_PASSWORD=your-secret ./start.sh
```
3. Open `http://<server-tailscale-ip>:8787` in your phone's browser
(find your server's Tailscale IP in the Tailscale app or with
`tailscale ip -4` on the server).
That's it. Traffic is encrypted end-to-end by WireGuard, and password auth
protects the UI at the application level. You can add it to your home screen
for an app-like experience.
> **Tip:** If using Docker, set `HERMES_WEBUI_HOST=0.0.0.0` in your
> `docker-compose.yml` environment (already the default) and set
> `HERMES_WEBUI_PASSWORD`.
---
## Manual launch (without start.sh)
If you prefer to launch the server directly:
```bash
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:
```bash
curl http://127.0.0.1:8787/health
```
---
## Running tests
Tests discover the repo and the Hermes agent dynamically -- no hardcoded paths.
```bash
cd hermes-webui
pytest tests/ -v --timeout=60
```
Or using the agent venv explicitly:
```bash
/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:
**5303 tests collected** across **488 test files**.

**[@Jordan-SkyLF](https://github.com/Jordan-SkyLF)** — Live streaming + UX polish (12 PRs, `v0.50.18` → `v0.51.58`)
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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/LumenYoung)** — Streaming hot-path correctness (4 PRs, `v0.51.47` → `v0.51.55`)
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](https://github.com/dobby-d-elf)** — Frontend reliability + motion polish (6 PRs, `v0.51.38` → `v0.51.58`)
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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/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](https://github.com/Bobby9228)** — Mobile Profiles button (PR #265)
Added the Profiles entry to the mobile navigation flow, making profile switching reachable on phones.
**[@kevin-ho](https://github.com/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](https://github.com/andrewy-wizard)** — Chinese localization (PR #177)
Initial Simplified Chinese (`zh`) locale. One of the first non-English locales.
**[@DelightRun](https://github.com/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](https://github.com/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](https://github.com/shaoxianbilly)** — Unicode filename downloads (PR #378)
Proper `Content-Disposition` with RFC 5987 `filename*=UTF-8''...` encoding so non-ASCII filenames download without crashing.
**[@lx3133584](https://github.com/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](https://github.com/betamod)** — Security audit (PR #171)
A comprehensive CSRF / SSRF / XSS / env-race-condition audit that shipped in v0.39.0.
**[@TaraTheStar](https://github.com/TaraTheStar)** — Bot name + thinking blocks + login refactor (PRs #132, #176, #181)
Configurable assistant display name, thinking/reasoning block display, and a login page refactor.
