An open-source AI agent that runs inside the browser
peerd is an agent tool that runs as a Chrome or Firefox extension. It can use the tabs and signed-in sessions already open in the browser, then read pages, click through them, and carry out tasks. It can also create isolated workspaces such as JavaScript notebooks, Linux , and small client-side apps.
It does not route work through a remote backend, has no telemetry, and uses API keys supplied by the user for the they choose. It supports Anthropic, OpenRouter, and local Ollama; Ollama can run without an API key or cloud bill because the model runs on the user’s own machine. API keys and chat history are kept in an encrypted local vault, and keys are only sent to the selected .
The project is still an experimental 0.x beta, so features and storage formats may change, and it should be used carefully because it can control the browser and store API keys.
Key points
- peerd runs as a Chrome or Firefox extension, not as a separate .
- It can read and drive open and check actions against the live page.
- It uses bring-your-own API keys and does not include a remote backend or telemetry.
- It can connect to Anthropic, OpenRouter, or local Ollama for model use.
- It is still an experimental beta, so security, permissions, and cost tracking need care.
