WebBrain
The sidebar agent for the rest of us
What is WebBrain?
Your browser, your models, your data. WebBrain is a free, open-source AI browser agent for Chromium browsers and Firefox. Run it locally with llama.cpp and most queries cost nothing — your data never leaves your device. It reads pages, extracts data, and automates tasks right from the sidebar. Prefer the cloud? Bring your own API key for OpenAI, Claude, OpenRouter, or 100+ OpenAI-compatible providers. Multilingual UI, token-conscious screenshots. MIT licensed.
