What fastbrowse is about
What makes it different
fastbrowse is an open-source browser agent that refuses to guess. Instead of inventing selectors, it indexes every button, link and field a page actually has, and its System One model, Jev, picks the next step from that list โ if it is unsure, it falls back to a standard approach rather than clicking blindly.
Every claim in a finished answer cites a verbatim quote from the page, with a link that scrolls to it, and schemas come back validated. Credentials, irreversible actions and spending stay under code control: a secret is typed only on the origin it was declared for, and submit, pay, delete and send all stop until you allow them.
From Agent Labs, the team behind Nebula, fastbrowse ships as a CLI, a Python library, Node and Go SDKs, an MCP server and a coding-agent skill. The free plan needs no card and includes $2 of runs a month; paid plans start at $29 a month.
