Awesome JEV

A curated list of TypeSafe [Jev](https://typesafe.ai/blog/introducing-system-one-models-and-jev) / System One ecosystem projects — official SDKs, agent skills, browser & computer-use demos, MCP connectors, routers, and community awesome-lists. Independent open-source typed-decision alternatives are listed separately and are not presented as official or drop-in compatible. The site groups GitHub projects by primary use and presents Jev news separately.
