Pi Web is a browser interface for the Pi coding agent. It reads the same local configuration and session files as Pi, so you can browse and resume conversations, run agent turns, configure models and resources, and inspect project files from a browser while changes stay visible to both interfaces.
It runs as a local server that binds to the loopback address by default. Remote access is opt-in, protected by a password login, and meant to sit behind HTTPS through a reverse proxy or a VPN. The file browser is limited to working directories and session roots that Pi Web already knows about.
Downstream integrations such as Electron wrappers can replace the session context menu through a browser event, and server-side Pi extensions can register session liveness to keep a session from idle eviction while detached work runs. An interactive demo runs the real UI in the browser with sample sessions and pre-written replies.
Features
- Session workspace: browse, resume, rename, export, and delete conversations grouped by project, with running state, context usage, cost, and compaction details
- Branching: start a new session from an earlier message, or branch inside the current session with Edit from here
- Project files: browse and upload files, inspect Git diffs, and preview source, Markdown, images, audio, PDFs, and DOCX files
- Git worktrees: switch checkouts from the sidebar while sessions from one repository stay grouped
- Web configuration: manage provider login, API keys, models, model tests, plugin packages, and skills
- Interface languages: English, Simplified Chinese, and Traditional Chinese, following the browser language
- Extension hooks: a session context-menu event for wrappers and a session-liveness registry for Pi extensions
