From the team that found jank at scale for Google Chrome

Removes the jank from anything you build with AI.

Code, docs, or a live URL — 10 AI jank-finders, ~3 min. Works in Claude Code, Claude Cowork, and OpenAI Codex.

Works in Claude Code, Claude Cowork, OpenAI Codex, Antigravity & Cursor.

Cloud Runs

Kick all cloud runs from inside your dev console /jank_cloud

Perform deep, parallel runs in the cloud of the code you're building locally — results in minutes while you keep coding, then Claude auto-fixes every issue it finds.
