Pixie 0.1.0

Watch your coding agent work

Pixie runs any model as a local coding agent and shows a coral pixel creature acting out what it is doing in real time: thinking, typing at a tiny laptop, sweeping a magnifying glass while it searches, scribbling edits, running a terminal, and chasing a bug while it debugs. Instead of a spinner, you get a glanceable picture of the agent's state.

Highlights

• Bring your own API key for Anthropic (Claude), OpenAI, Google Gemini, OpenRouter, Ollama, or any OpenAI-compatible endpoint. The default model is claude-opus-4-8.
• Zero runtime dependencies. One command starts a local server and opens the browser; there is no build step and nothing to install beyond Node 18.17 or newer.
• Seven tools (read, write, edit, list, glob, grep, run shell) behind a permission gate you control: read-only actions run freely, edits and commands ask first, and catastrophic commands are refused even in auto-approve mode.
• File access is sandboxed to the folder you launch in (symlink escapes included), and provider keys are scrubbed from the shell environment before commands run.
• Streaming replies, live token counts, light and dark themes, and a reduced-motion fallback for the mascot.
• Covered by a node:test suite (run npm test).

Install and run

Run node bin/pixie.js inside the project you want to work on, then paste an API key in the settings panel.

Limitations

• Conversations are kept in memory; restarting the server clears them.
• It works in one directory per launch, the folder you start it in.
• It is a local, single-user tool. It binds to 127.0.0.1 with no authentication, so do not expose the port to a network.
• Local models without native function calling fall back to a JSON tool format, which is less reliable than native tool calls.
