Integrations — built on Jev
Glue code that puts Jev decisions inside tools you already run — coding agents, agent frameworks, MCP servers, validation libraries, and databases. These projects are community-maintained and typically require your own Jev API key.
Integrations are the fastest way to evaluate Jev without rewriting an application: install the plugin, point it at an API key, and let it replace a slow generative step with a typed one.
