we built blazing fast computer/browser use with Jev + @Stagehanddev.

this task cost $0.001 and executed at near instant speed (in a remote browser btw)

the loop: observe the page, send a11y tree as state + actions as questions, Jev decides the next action, then Stagehand

How builders describe it

Observe the accessibility tree, Jev chooses the next action, Stagehand executes.
Kyle Jeong's demo of browser use with Jev and Stagehand: the accessibility tree is the state, actions are the questions, and one remote-browser task cost $0.001 at near-instant speed.

The decision Jev makes

Pick the next click, field or navigation from the legal actions on screen.

Where it fits

Browser agents need to choose an action on every step. With Jev each step is a choice from the actions actually available on the page, which keeps agents fast and on the rails. All 299 agents & browsers projects →
