Jev Users

About this directory

Jev Users tracks open-source projects built on Jev, TypeSafe AI's System One model for fast, typed, confidence-aware decisions (Choice, Score and Noul with calibrated probabilities).

This is an unofficial, community-run directory. It is not affiliated with, endorsed by, or operated by TypeSafe AI.

How the list is built

  1. Discovery. Six GitHub search queries run daily, covering repository names, descriptions, the jev topic, and README text.
  2. Filtering. Substring collisions get removed — a smart-vision framework, an EVE Online asset manager and a camera viewer all contain "jev" but have nothing to do with this ecosystem.
  3. Weighing the signal. Naming Jev in the repository name or description counts as a strong claim. A bare jev topic does not: it is cheap to add and gets used as a traffic tag, so those repos only make the list if their README backs it up.
  4. Rescuing quiet repos. Several real projects ship no description and no topics at all. Rather than drop them, their READMEs get checked directly.
  5. Ranking. Sorted by GitHub stars, top 100 kept. A daily snapshot of every project's star count feeds the 7-day trend column.

Corrections

Ranking by stars is objective but blunt: a large project that merely integrates Jev can outrank a tool built entirely around it. If something is miscategorised, missing, or does not belong, say so and it gets fixed by hand.
