 "what": "Jev Ultrafast is a browser agent from Browser Use with a dynamic, indexed action space. Each page becomes a numbered element table, TypeSafe's Jev picks one operation (CLICK, TYPE_TEXT, SELECT, SCROLL, WAIT, DONE or BLOCKED) and a target in one network round trip, and a small LLM writes text only when the operation is TYPE_TEXT. The README shows a Zurich to London Google Flights search in about 7 seconds.",
 "why": "24k stars, launched 40 days ago, picked up by one AI source we track",
 "language": "Python",
 "requirements": [
  "Python with uv",
  "Chrome with remote debugging allowed (connected through Browser Harness, installed by uv sync)",
  "TYPESAFE_API_KEY and TEXT_MODEL_API_KEY (an OpenRouter key in the example config)",
  "Live examples make paid API calls"
 ],
 "audience_note": "Developers building fast web agents who want fewer model calls, no screenshots in the loop and a codebase small enough to read.",
