RA Browser Use
A Chrome browser-automation agent, forked from Nanobrowser, that runs its model on-device inside the extension by default, so a task in plain language runs with no API key, no cloud call and no page content leaving the browser.
RA Browser Use is an openly declared fork of Nanobrowser, a multi-agent browser automation extension, adapted to run its model on-device by default instead of only against a cloud LLM provider or a separately installed Ollama process.
Given a task in plain language, it navigates, clicks, types and extracts data on a Chrome page, with the model executing inside the extension itself through WebAssembly and WebGPU via the RunAnywhere SDK. In this default mode nothing needs to be configured, a model is picked automatically for the user's hardware, no page data leaves the browser, and there is no per-token cost. Cloud providers are still supported for tasks that need a larger model.
Upstream's full commit history is merged rather than squashed, and its live git remote is tracked to pull forward Nanobrowser's own fixes. It is Apache-2.0 licensed and, as of this writing, in early development and not yet released.
