fastbrowse

Lets fastbrowse runs work in this browser, where you are already signed in, without a remote debugging prompt.

Description fastbrowse is a browser agent you run from your terminal, your code or an MCP client. This extension lets a fastbrowse run on your computer work in the browser you already use, with your sign-ins, instead of starting a separate one. How it works - Install fastbrowse, then run `fastbrowse extension install` once. That registers the small local program the extension talks to. - Start a run with `fastbrowse --extension "your task"`. The run opens its own tabs in a tab group named after its task, and works only in those tabs. - The extension's toolbar button lists the runs working in this browser, each with a Stop button. Closing a run's last tab also stops it. - When a run ends, the tabs it opened close. Some extensions add a frame of their own to every page, such as screen recorders and password managers. Chrome does not let fastbrowse work in a tab that holds one, so a run there stops and names the extension: set that extension's Site access to "On click" and run again. Several runs can work at once, each in its own group. With more than one browser connected, name one in the extension's popup and pick it with `--extension-browser`. Privacy The extension talks only to the fastbrowse program on the same computer, through native messaging. It sends nothing to any server itself, collects no analytics, and stores only a random identifier for the browser and the name you give it. Chrome shows a bar saying fastbrowse started debugging this browser while a run is working; pressing Cancel on it stops the run. Learn more: https://www.fastbrowse.ai
