Jev Top Repos

One page, three tracks. Jev-Based is built around TypeSafe Jev as the core. Jev Integrations are larger products that call Jev. OSS alternatives are public GitHub System One–class replicas that are not TypeSafe Jev. Each track is ranked by public stars on its own 1…N — not a quality award, not a TypeSafe leaderboard.

401 ranked repos(307 Jev-Based · 57 Jev Integrations · 37 OSS alternatives). We do not pad the tables. OSS alternatives are labeled as such and are not Jev. Canonical product facts stay on docs.typesafe.ai.

Jev-Based

Repositories built around TypeSafe Jev / System One as the core — official SDKs, decision harnesses, and Jev-native demos. Hard TypeSafe Jev evidence required (not a system-one topic tag). Rank is public stars only, not a quality award. 307 ranked on this track.

FAQ

What is this ranking?

A snapshot of public GitHub repositories we judged related to TypeSafe Jev or the System One class, split into three tracks. Rank is public GitHub stars only: each track is sorted by star count descending (ties break onowner/name), then numbered 1…N on that track. Rank is not quality, momentum, or official endorsement.

What is Jev-Based vs Jev Integrations vs OSS alternatives?

Jev-Based means the repo is built around TypeSafe Jev as the core — official SDKs, decision harnesses, and Jev-native demos, with hard TypeSafe Jev evidence. Jev Integrations are larger products that call or integrate TypeSafe Jev. OSS alternativesare public GitHub System One–class / typed-decision replicas that arenot TypeSafe Jev (Laya, SemIf, NanoJev, Kev, and similar). Closed or no-repo competitors stay on Comparisons. We do not call any track “Best” or “Centered.”

How many repos are ranked?

No fixed N — we do not cap or pad the tables. This pass ranks401 related repositories that passed verification (live GitHub plus a TypeSafe Jev / System One evidence gate). Awesome-* meta lists are harvest seeds only and stay off the ranking. Each track is 1…N by public stars for however many pass.

Are these official TypeSafe projects?

Only rows under typesafe-ai/ are vendor repositories. Everything else is community work. jev.pro is independent and unofficial. We do not sell or issue API keys.

How do stars and 1d / 7d / 30d refresh?

A scheduled GitHub Action (no LLM) pulls public star, fork, and watcher counts from the GitHub API. 1d / 7d / 30d are live stars minus the daily snapshot from about 1, 7, or 30 days ago. A missing baseline shows — — we do not invent a gain from total stars or a stale prior Δ. Metrics stay global; each track is re-sorted by public stars at render time so rank cannot drift from the star column. Deep-page prose stays editorial. Rank is still public stars only — not a quality score.

What do the categories mean?

  • SDK. Clients and adapters that call hosted Jev or a Jev-shaped API.
  • Harness. Agent skills, MCP servers, and loops that ask Jev to decide.
  • Demo. Runnable products and experiments that put a decision model in a loop.
  • Eval. Open replicas, local runtimes, and independent measurement — not Jev.
  • Docs. Curated indexes, galleries, and field notes around the ecosystem.
  • Integration. Bridges into databases, browsers, CI, or another runtime.
