AI Agent
peerd
peerd is the first AI agent harness native to the browser, allowing AI agents to drive tabs, run sandboxed compute, and share peer-to-peer with no backend.

What is peerd?
peerd is an open-source browser extension that runs AI agent loops directly in the browser. It reads and drives your tabs, spins up sandboxed compute (JS notebooks, WASM Linux VMs, client-side apps), and shares what it builds over a peer-to-peer WebRTC network. BYOK to the model provider of your choice, with no backend, no telemetry, and no cloud component in the data path.
