Integrations
Vercel AI Gateway, eve, LangChain, Postgres, Home Assistant, n8n, and platform glue.
Where Jev meets the stack you already run. Gateways, agents, databases, and home automation. These projects embed evaluate paths into the Vercel AI SDK, LangChain, or HA flows. Look for demos that show structured questions, not giant chat prompts. Gateway routes are great for prototypes; direct TypeSafe credentials may fit better at volume or with private networking.

pg-jev is a Postgres extension for people who already filter rows in SQL. The jev() function judges each row in plain language without embeddings or a vector index. Zachi's launch clip judged 129 rows in about one second for about $0.0009, with cache hits near 6 ms on a second run.
