# Hermes Web UI — Roadmap

> Web companion to the Hermes Agent CLI. Same workflows, browser-native.
>
> Last updated: v0.51.192 (May 31, 2026) — ~7,150 tests collected. Recent themes: forward-looking ruff lint gate (#3273), Windows upgrade state-stranding hotfix (#2905), per-model context_length default-only guard (#3256), gateway-configured banner + tooltip i18n, and an ongoing concentric PR-triage cadence.
> Test source: `pytest tests/ --collect-only -q`
> Per-version detail: see [CHANGELOG.md](./CHANGELOG.md)

## Status snapshot

| Surface | Status |
|---|---|
| **Hermes CLI parity** | ✅ Complete — every CLI workflow has a web equivalent |
| **Streaming + tool transparency** | ✅ Live tool cards, reasoning cards, approval prompts, cancel |
| **Multi-provider model support** | ✅ Any provider configured in `config.yaml` shows in the picker |
| **Sessions + projects + search** | ✅ CRUD, content search, projects, tags, archive, fork, import |
| **Mobile + Docker + auth** | ✅ Hamburger nav, slide-overs, password auth, GHCR images |
| **Auxiliary surfaces** | ✅ Workspace tree + edit, cron CRUD, skills CRUD, memory write, MCP server UI |
| **Visual polish** | ✅ Light/dark/system themes × 11 skins (default, ares, mono, slate, poseidon, sisyphus, charizard, sienna, catppuccin, nous, geist-contrast), Mermaid, KaTeX, syntax highlighting |

## Architecture

| Layer | Files | Status |
|---|---|---|
| Python server | `server.py` + `api/` modules | Thin HTTP shell + auth middleware over the `api/` business logic (config, sessions, streaming, profiles, routes, onboarding, workspace, updates, upload) |
| HTML template | `static/index.html` | Served from disk |
| CSS | `static/style.css` | Themes + skins, mobile responsive, KaTeX, table styles |
| JavaScript | `static/{ui,sessions,messages,workspace,panels,boot,commands,icons,i18n,login,onboarding}.js` | Vanilla-JS modules served as static files — no bundler |
| Service worker | `static/sw.js` | Offline shell cache, version-pinned assets |
| Docker | `Dockerfile`, `docker-compose.yml` | `python:3.12-slim`, multi-arch (amd64+arm64), HEALTHCHECK |
| CI/CD | `.github/workflows/` | ruff lint + sharded pytest + browser smoke + Docker smoke on every PR; auto-release + GHCR publish on tag push |
| Test isolation | `tests/_pytest_port.py` | Per-worktree port + state-dir derivation, no collisions |

> Per-file line counts drift every release; see `ARCHITECTURE.md` for the current module map and `git ls-files` for exact sizes.

## Forward work

### Confirmed candidates (open feature requests with sprint-candidate or active interest)

| Theme | Tracking | Why |
|---|---|---|
| Persistent-host stability | #1458 | Bootstrap fork pattern crashes under launchd / systemd — partial fix shipped (foreground mode); state.db FD leak and HTTP-unhealthy wedge remain |
| Free-tier OpenRouter variants visible | #1426 | `:free` tool-support filter currently hides them from the picker |
| macOS scroll override regression | #1360 | Auto-scroll sometimes overrides user scroll on the desktop app |
| GLM dual-use (main + auxiliary) | #1291 | Currently mutually exclusive; same provider can't serve both surfaces |
| Auto-assign session to filtered project | #1468 | When user is filtering by project X, new session should default to project X |
| Update banner "What's new?" link | #1512 | Surface release highlights from the update banner |
| Sunset legacy `LMSTUDIO_API_KEY` env var | #1502 | Tracking issue — alias stays for one minor cycle, then removed |
| Hermes Agent dashboard cross-link | #1459 | Detect a running Hermes Agent and surface link in nav |
| Gateway status card in Settings | #1457 | Current gateway-status dots only on profile picker |
| Insights — daily token chart + per-model breakdown | #1456 | Existing usage badge is per-message; need rollup view |
| Logs tab — view agent / errors / gateway logs | #1455 | Currently requires terminal access to log files |
| Model picker collision handling | #1425 | Same-name models from different providers aren't disambiguated in dropdown |
| "Reveal in Finder" right-click on workspace | #1424 | macOS desktop app convenience |
| Configurable session persistence timing | #1406 | Currently every checkpoint, want operator control |
| Silent credential self-heal on 401 | #1401 | Gateway auth.json drift should resolve without user re-auth |
| LLM Wiki status panel | #1257 | On / off toggle for Wiki integration |
| Lightweight in-app Canvas editing | #1255 | Text canvas for prompt drafting / shared notes |
| Provider / Model source-of-truth alignment | #1240 | Reconcile WebUI vs CLI vs Gateway provider resolution |
| Built-in SearXNG web search | #1037 | Lightweight search tool with on / off toggle |
| Subagent session relationship view | #1004 | Show subagent hierarchy in sidebar with expand / collapse |

### Backlog (deferred, listed for visibility)

- **Insights / monitoring suite** — agent heartbeat + alerts (#716), quota / rate-limit display (#706), data tabs (#722), monitor dashboard concepts (#766, #721)
- **Native MCP server expose** — Hermes WebUI as an MCP server for direct agent integration (#733)
- **Teams / agents management panel** — editable names, roles, assignments (#719)
- **Web UI profile model alignment with Hermes runtime** — design parity (#749)
- **DOM windowing / message virtualization** — for sessions with hundreds of messages (#734)
- **Searchable global tool list** (#697)
- **Add agent / replace model modals** (#698)
- **Code execution inline cells** — Jupyter-style cell rendering inside chat
- **Sharing / public conversation URLs** — requires hosted backend with access control (out of scope for self-host)

### Intentionally not planned
- Full SwiftUI rewrite of the frontend — the WKWebView shell already gets 95% of native benefit
- App Store distribution — sandboxing breaks the local server model
- Real-time multi-user collaboration — single-user assumption throughout
- Plugin marketplace — Hermes skills cover this surface
- Anthropic / Claude proprietary features — Projects AI memory, Claude artifacts sync (not reproducible)
