awesome-jev on GitHub (heyjunpenn/awesome-jev)

Q: What is this?

A verified, community-maintained catalog of open-source projects built with Jev — TypeSafe AI's System One model for typed decisions inside software. The README snapshot covers 832 unique public GitHub repositories.

Q: What is Jev, the thing all these projects are built with?

TypeSafe AI's System One model: instead of writing prose, it answers typed questions — Choice, Score, and Noul — and returns calibrated probabilities, so code can branch on a judgment instead of parsing text.

Q: Where should someone new start in the list?

Start with the six Official entries — the TypeSafe agent skills and the Python and TypeScript SDKs (pip install typesafe-sdk, npm install @typesafe-ai/sdk) — then jump to whichever section matches what you want to build.

Q: How fresh are the numbers — is the star count a ranking?

No — stars were captured on 2026-09-18–23 as a discovery aid, not a ranking, and the README says to verify behavior, activity, and licensing upstream. It grows fast: 192 projects were added on September 23, 2026 alone, and the repo description already counts 981.

Q: Which category gets the most coverage?

Agent tooling, with 209 entries, followed by Applications (111) and Benchmarks & research (109) — the ecosystem so far is mostly agent infrastructure and SDKs rather than polished end-user apps.

Q: Do entries do more than just link a repo?

Yes — every entry names the concrete decision Jev makes in that project and links to the strongest public evidence, so you can judge real implementations rather than project claims.

Q: Is the catalog available in other languages?

Yes — the README ships in six languages: English, Simplified Chinese, Japanese, Korean, Spanish, and Brazilian Portuguese.

Q: Is Awesome Jev an official TypeSafe AI project?

No — it is independent and community-maintained, with no affiliation to or endorsement from TypeSafe AI; it catalogs what the community builds around their model.

What is this?

A verified, community-maintained catalog of open-source projects built with Jev — TypeSafe AI's System One model for typed decisions inside software. The README snapshot covers 832 unique public GitHub repositories.

What is Jev, the thing all these projects are built with?

TypeSafe AI's System One model: instead of writing prose, it answers typed questions — Choice, Score, and Noul — and returns calibrated probabilities, so code can branch on a judgment instead of parsing text.

Where should someone new start in the list?

Start with the six Official entries — the TypeSafe agent skills and the Python and TypeScript SDKs (pip install typesafe-sdk, npm install @typesafe-ai/sdk) — then jump to whichever section matches what you want to build.

How fresh are the numbers — is the star count a ranking?

No — stars were captured on 2026-09-18–23 as a discovery aid, not a ranking, and the README says to verify behavior, activity, and licensing upstream. It grows fast: 192 projects were added on September 23, 2026 alone, and the repo description already counts 981.

Which category gets the most coverage?

Agent tooling, with 209 entries, followed by Applications (111) and Benchmarks & research (109) — the ecosystem so far is mostly agent infrastructure and SDKs rather than polished end-user apps.

Do entries do more than just link a repo?

Yes — every entry names the concrete decision Jev makes in that project and links to the strongest public evidence, so you can judge real implementations rather than project claims.

Is the catalog available in other languages?

Yes — the README ships in six languages: English, Simplified Chinese, Japanese, Korean, Spanish, and Brazilian Portuguese.

Is Awesome Jev an official TypeSafe AI project?

No — it is independent and community-maintained, with no affiliation to or endorsement from TypeSafe AI; it catalogs what the community builds around their model.

What are similar projects?

awesome-jev-live, awesome-jev, awesome-jev-projects, awesome-jev, awesome-mcp-servers, awesome-jev, awesome-remote-mcp-servers, public-api-lists

Which topics is it in?

typesafe, decision-making, community-driven, jev, astro, directory, static-site, computer-use, catalog, i18n, multilingual, awesome
