Highlights
- The catalog groups entries into 11 categories and names the language and license for each project it lists.
- Category mix on the site includes agent tooling, frameworks and integrations, browser and computer use, and Jev-like models.
- Stars were captured on 2026-09-18 through 22 for discovery rather than ranking, and 110 projects were added on September 22, 2026.
- Says it is not affiliated with or endorsed by TypeSafe AI, and warns that schema-valid output is not the same as a correct decision.
- Each entry identifies the concrete decision Jev makes and links to the strongest public evidence available for it.
Watch out
MIT-licensed and independent, not affiliated with or endorsed by TypeSafe AI; star counts are a dated snapshot and linked projects keep their own licenses.
Questions about this entry
Short answers drawn from the linked project or page.
It is a community catalog, explicitly not affiliated with or endorsed by TypeSafe AI. The docs describe the model and its three primitives; this lists what people actually built, with each entry naming the concrete decision Jev makes and linking to the strongest public evidence for it. Official SDKs and tooling have their own section.
Treat them as discovery aids, not rankings. The README says star counts were captured for discovery rather than ranking and tells you to verify current behavior, activity and licensing upstream, since they age. Coverage is also lopsided: agent tooling has hundreds of entries while classification and voice have a couple each.
Community clients for Scala, Ruby, Java, Elixir, PHP, Go, Swift, Rust, Haskell, C# and PowerShell sit alongside the official Python and TypeScript SDKs, each with its own license line. A separate section of Jev-like models covers open checkpoints you can run locally instead of calling TypeSafe.
No. Inclusion is a catalog decision, not a correctness claim, and the list itself warns that schema-valid output is not the same as a correct decision. Entries arrive through an issue template, so treat every one as a lead to evaluate on its own behavior and licensing before you depend on it.
981 unique public GitHub repositories across 11 categories and 29 languages, with counts per section: official 6, SDKs and clients 60, Jev-like models 83, frameworks and integrations 88, agent tooling 236, browser and computer use 77, applications 134, games and simulations 73, demos and playgrounds 66, benchmarks and research 116, and other lists 42. Each table names language and date added alongside the stars.
Each entry has to identify the concrete decision Jev makes in that project and link to the strongest public evidence available for it, which is the stated reason the catalog exists over a plain link list. Linked projects keep their own licences, and the catalog itself is MIT and independent, not affiliated with or endorsed by TypeSafe AI.
There is, at jevbest.com, with the README pointing to it as the way to explore. The README is a dated snapshot: 981 repositories with stars captured on 2026-09-18 through 2026-10-04, explicitly for discovery rather than ranking, and it tells you to verify current behaviour, activity, and licensing upstream. A changelog tracks what changed.
