10 open-source projects built on Jev in two weeks
A roundup of 10 open-source projects that actually use Jev for decisions, including playing Mario, flying a drone, a 1v1 shooter, a trading bot, knowledge-graph walking, dataset filtering and second-guessing a coding agent, all with GitHub links.
Jev went from "what is that" to everywhere in about two weeks. If you already have Jev API access and don't know what to build first, here are 10 open-source projects people actually shipped with it: 1. typesafe-mario Jev plays Super Mario. No screenshots. It reads the game state from the emulator and decides: run, jump or wait. http://github.com/fhshaik/typesafe-mario 2. jev-drone A camera-only drone in a MuJoCo sim. The flight controller keeps it stable, Jev makes the calls on top at 2.5 times a second. http://github.com/RomanSlack/jev-drone 3. OneVOneJev A 1v1 shooter in the browser built on Three.js. Every tick Jev decides where to move, where to aim and when to fire. http://github.com/emrickgarrett/OneVOneJev 4. jev-trader One trade decision every Monad block. Jev watches the Kuru MON-USDC book and answers buy or sell about every 300 ms. http://github.com/jarrodwatts/jev-trader 5. neo4jev Jev walks a Neo4j knowledge graph. At every node it picks the next relationship worth following. http://github.com/jexp/neo4jev 6. jev-curate A dataset filter. It reads JSONL or Parquet rows, scores quality and relevance, and decides what goes into the next training run. http://github.com/AkashPriyadarshii/jev-curate 7. Canny Stops coding agents from saying "done" without proof. Hooks check the evidence, Jev gives the second opinion. http://github.com/qkal/Canny 8. killmyidea Describe a startup idea. Jev scores it from several angles and returns KILL, FIX or SHIP. http://github.com/monteduro/killmyidea 9. jev-opus Runs Claude Opus 5.5 and lets Jev pick the effort level for every step, without breaking the prompt cache. http://github.com/WXK-AI/jev-opus 10. awesome-jev A curated list of public Jev projects and integrations, for when you've finished these nine. http://github.com/yibie/awesome-jev Same pattern in all ten: the model doesn't write anything. It answers one typed question and your code acts on it.
