Curated list of 74 Jev demos and 150+ repos with costs and limits
A ranked list covering repos that use Jev to shortlist files for Claude, pick fast or strong models per message, compact context and block dangerous commands, plus real costs and known limits.
Stop building with Claude Code until you've seen these Jev repos. Hurry up odds are someone already shipped your idea. open source, with benchmarks. there's a list that tracks it all: 74 Jev demos ranked by likes, 150+ repos, real costs and the model's known limits. the best stuff in it is what nobody reposts: Claude reads 187 files to find the 4 that matter? -> quicksilver. Jev skims them all, Claude gets the shortlist https://github.com/UditAkhourii/quicksilver paying for the strong model on every tiny message? -> jev-router. Jev picks the fast or strong model before each one https://github.com/gargpratyush/jev-router Claude loses details every time the chat gets compacted? -> fast-jev-compaction. Jev drops stale tool calls, keeps the rest word for word https://github.com/tamaratran/fast-jev-compaction your agent says "done" without running a single test? -> Canny. no evidence, no finish https://github.com/qkal/canny worried your agent runs something it shouldn't? -> jev-guard. Jev scores every action, rm -rf gets blocked https://github.com/leepokai/jev-guard one rule before you build: read the limits section. Jev reads literally and it's weak at math, counting and dates. keep its input small and let code do the math. there's even a section of ideas nobody has shipped yet. your next build might be sitting there. save this now. in a week it's buried under 500 other posts, and you'll be rebuilding one of these from scratch.
