How builders describe it

Write browser, desktop and mobile end-to-end tests in plain English YAML: Playwright, xa11y or Appium perform the actions while Jev reads the accessibility tree to select the element each step describes and to judge each expect claim; coding agents can explore a flow via MCP and save it as a spec.

The decision Jev makes

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

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 →
