fastbrowse is a browser agent for tasks like sign-in, form filling, checkout, and lookups. It’s for teams that don’t want an agent to “make up” selectors from screenshots, and who want the final answer to be grounded in what the page shows.
It indexes the page into the interactive controls that are actually present, then has Jev pick the next action from that set. Deterministic code handles verification, authorization gates, and secrets, and the agent’s output is tied to verbatim page quotes (with what it read).
--authorize (otherwise it stops at needs_confirmation).--secret), so a password can be named without being sent to a model.
--cloudThe tool is MIT licensed and is designed to finish the task and cite what it read, not just produce an unverified answer. The supplied results report 71x lower median cost per task ($0.0057 vs $0.4070) and tie reliability in a head-to-head setup (fastbrowse 41/42 vs Browser Use 42/42, with no cost cap on either side).
