What is it?
Saved flows are the headline of agent-browser 0.42.0, released on November 10, 2026. The experimental feature records a browser task once and replays its requests later, so an agent does not have to click through the same pages again. agent-browser itself is Vercel Labs' Rust CLI that lets an AI agent drive a browser one shell command at a time.
How does it work?
A replay tries the cheapest path first: direct HTTP requests, then requests sent from inside the page, then a replay of the recorded commands, and it saves whichever tier worked. Runs only contact public addresses. The rest of the tool is unchanged: accessibility-tree snapshots give each element a ref like @e1, and a per-session daemon controls Chrome over the DevTools Protocol.
Why does it matter?
Repeated browser chores, such as checking a dashboard or submitting the same form, cost an agent many snapshot-and-click steps. Replaying the underlying requests can turn them into a few fast calls. The release also fixes session reuse and Safari/iOS sessions and tells agents to prefer snapshots over screenshots; the npm package now needs Node 22 or later.
