About JevDirectory.org
JevDirectory.org is an independent, community-run directory of the Jev ecosystem — TypeSafe AI's System One decision model. It collects the repos, SDKs, cookbooks, tools, patterns, and guides worth a developer's time, and adds original guides to designing with Jev.
It is free to browse and not affiliated with TypeSafe AI. Jev and System One are TypeSafe AI trademarks; official entries are marked as such and link back to TypeSafe.

How entries are chosen
Every entry is hand-picked against the same bar, whether it comes from TypeSafe or the community.
- Public and working — no paywalls, sign-up walls, or dead links.
- Concrete — about Jev and the System One API, not generic LLM content.
- Useful today — something a developer can learn from or use right now.
- Distinct — the description says what makes it different from a near neighbour.
- Documented — repos state their licence, and docs are in English or summarised in it.
Spam, affiliate links, and thin AI-generated content are rejected. Each entry carries a description, and most carry a verified deep dive: highlights, caveats, a quickstart snippet, and the date the link was last checked.
Independence
Paid placements and sponsorships are clearly labelled and never change what gets listed or how it ranks. The directory takes no payment for inclusion.
Corrections and authorship
