Web UI
Besides the terminal TUI, AtomCode ships a built-in browser interface: type /webui in the TUI to launch it, then chat, browse session history, add/edit/delete model providers, and upload images in the browser — and use /sync to mirror one session live between the terminal and the browser. It reuses this machine's login, models, and session history, so there's nothing extra to configure.
Start & stop
Run these in the AtomCode TUI input box:
# Launch the webui and open the browser (binds 127.0.0.1:13457 by default — local only)
/webui
# Stop the webui server
/webui stopOn launch, AtomCode starts a local HTTP server and opens your browser to a URL like http://127.0.0.1:13457/?token=<one-time token>. The token in the URL is the credential — it's equivalent to a password, so don't share it. The current TUI session is also attached to live sync automatically (see Live sync across devices below).
The webui binds 127.0.0.1, reachable only from this machine. To open it from a phone, do not expose it with --host 0.0.0.0; use the 蒲公英 virtual-LAN approach instead — see Remote Access.
What the interface offers
The browser UI brings the terminal's capabilities into a graphical interface:
| Area | What you can do |
|---|---|
| Sidebar | Session history grouped by project, search sessions, start a new chat, rename / delete sessions; collapses to an icon rail (a drawer on mobile). |
| Model selector | Switch provider / model right under the input box; same-named models are disambiguated with a provider tag. |
| Model config | Add / edit / delete providers in settings: name, type (openai / claude / ollama), model, Base URL, API key, context window, and set-as-default. |
| Settings | Theme (light / dark), language (中 / EN), model config, and the remote-access entry. |
| Image attachments | Paste or pick images to send with a message (2 MB each); non-vision models fall back to VL; thumbnails show in history. |
| Tool execution | Tool calls show their arguments and output inline, expandable line by line, both live and in history. |
| Attach menu (+) | Upload an image, pick a file for context, or insert a Skill. |
| Working directory | Switch the working dir, browse folders, create a new folder, set a default working dir. |
Live sync across devices
Behind the webui is a LiveSession: one session can be open in the terminal and multiple browser tabs at once, and every input, streamed AI reply, and tool result is broadcast live to all connected views — a viewer that joins late first receives a snapshot replay.
- When you run
/webui, the current TUI session is attached automatically — messages you send in the terminal appear in the browser, and vice versa. - In another TUI, run
/syncto attach to the running webui session (a/webuimust already be running). /sync off— leave sync and return to a standalone session.
This makes "start in the terminal, watch progress on a phone / tablet" — or several people watching the same agent session — possible.
Remote access
Want to open the webui from a phone without exposing it publicly? Use a 蒲公英 (Oray PGY) virtual LAN: bind the server to the virtual IP with /webui --host <virtual IP>, then scan the QR in the Remote Access panel. Full walkthrough in Remote Access.
