peerd: the AI agent harness native to the browser

Website ↗ Repo ↗ Full dossier ↗

What it does

peerd is a browser extension that runs a full agent harness inside the browser you already use. The agent can drive your tabs and signed-in sessions, run sealed JS notebooks, compiled WASI tools, client-side apps, and WASM Linux VMs, and — on preview builds — talk to other peerd browsers over WebRTC.

The homepage thesis: native and cloud apps drive the browser from outside; peerd lives inside it. No background host process, no sidecar, no peerd cloud, no external tool broker. Model calls go to the provider you configured (or local Ollama / planned WebGPU). Current builds send no product telemetry to peerd.

Category honesty: this is a harness, not a remote browser-as-a-service. Browser & Web Execution in this catalog is for managed / remote browser sessions. peerd inverts that: the user’s browser is the runtime, hypervisor, and control plane.
