Jev Ultrafast runs browser agents in seconds, not minutes

Most browser AI agents move at a crawl, but a new open-source framework just searched Google Flights in 7.1 seconds.

The creators of browser-use released Jev Ultrafast, a light agent framework that picked up 2,064 GitHub stars this week. Instead of burning time on screenshot processing, it turns web pages into structured element tables. It bundles operation and target decisions into a single network request, calling a small text model only when a field requires typing.

Why it matters: Web agents are usually slow because they process heavy vision data and make multiple API calls per action. Jev skips vision in its main loop and interacts directly with atomic browser nodes. It speeds up automation while keeping safety guardrails intact; the model never runs raw shell commands or arbitrary JavaScript.

To test the demo, clone the repository, run uv sync, and start the app with uv run jev. You will need API keys for TypeSafe and a text model helper like OpenRouter.

Finally, an agent that moves fast enough that you cannot go make coffee between clicks.
