Jev in production › SDKs and workflow integrations
Jev-compatible decision calls pass through a proxy that logs every request and trains a small owned model to replace Jev.

Dopp is a proxy for Jev-compatible decision APIs. Point your app's base URL at it instead of Jev: the requests and replies stay the same, and every request is kept. Label them, or pick an LLM or any other service to label them for you. Then train a small open model on them on your own CPU and let it answer, with Jev as the fallback. The model also runs offline or in a browser tab.
See the whole loop in about three minutes, with no keys or accounts. You need Node 22+ and uv:
