Jev Playwright

A field report on putting Jev inside a Playwright browser-testing loop: two Jev calls per probe, 63 probes in 24.3 seconds, and a 131 ms median round trip, with a candid account of near coin-flip decisions.

Open-source, pre-alpha CLI that runs plain-English browser tests on Playwright, using Jev for bounded decisions: resolving each step, picking elements among offered candidates and judging verify claims with probabilities. Bring your own TypeSafe key; MIT licensed.

A Playwright-based CodexQA skill where Jev chooses indexed controls on a page-built index while the browser executes the action.

Unofficial browser automation where the calling LLM states the outcome and Jev decides each element, action, and value from a Playwright page snapshot. Ships as a library, CLI, and MCP server.

Control a headed Chromium window by voice: one Jev request per partial transcript decides intent, target, and completeness in roughly 300 ms, while code applies thresholds and builds the action.
