About Pi Web

Pi Web is an open-source local web interface for the Pi coding agent that turns Pi's terminal sessions into a full browser workspace. It reads local Pi session files and surfaces conversation history so developers can pick up prior work by project rather than digging through terminal history or session paths. From the UI, users continue or fork earlier messages to try different directions safely, switch Git worktrees from the sidebar to work across branches, and preview source code, docs, images, audio, and PDFs beside the chat. It also centralizes agent housekeeping — model selection, login/API keys, model tests, and skill switches — into one place. Distributed as an npm package (@agegr/pi-web), it runs on Node 22.19.0+ and opens a browser at http://127.0.0.1:30141.

Key Features

Session Browser: Reads local Pi session files and organizes prior conversations by project for quick resume.
Fork and Continue: Continue from any earlier message or fork a session into a separate route to try alternatives safely.
Git Worktree Switcher: Switch between Git worktrees from the sidebar to work on multiple branches in parallel.
File Preview: Side-by-side chat and project file browser that previews source, docs, images, audio, and PDFs.
Model and Skill Manager: Configure models, API keys, run model tests, and toggle skills from the web UI instead of CLI flags.
Local-Only Runtime: Runs on http://127.0.0.1 by default so session data and code never leave the developer's machine.

Use Cases

Resume Prior Work: Reopen a conversation from last week by project instead of scrolling terminal history.
Safe Experimentation: Fork a session to try a risky refactor without losing the original conversation state.
Parallel Branch Work: Switch Git worktrees mid-session to jump between feature branches in one workspace.
Model Comparison: Rerun the same task against different configured models to compare output quality.
In-Browser Code Review: Preview generated diffs and project files beside the chat without leaving the browser.
