Jev on GitHub: official repos and top projects

No. Jev is closed and used through TypeSafe's API, so its weights and training code are not published. What is on GitHub is the tooling around it: TypeSafe's SDKs, an agent skill, evaluation code and examples (table above), and a large number of independent projects.

• What is Jev?
• How to use Jev

These are the most-starred independent projects that use Jev, with the description each repository gives itself. They are not affiliated with TypeSafe unless stated, and listing them is not an endorsement.

• browser-use/jev-ultrafast (22,991 stars): a web agent described as the fastest and cheapest, from the browser-use project.
• jev-chat/jev-chat-jarvis (7,782 stars): a chat assistant that reads a conversation, judges intent and risk, and drafts replies you send yourself, with versions for Android, Windows, macOS and iOS.
• tamaratran/fast-jev-compaction (7,644 stars): a Claude Code plugin that replaces the compaction summary with Jev decisions about which tool calls and results to keep.
• jarrodwatts/jev-trader (3,002 stars): one AI trade decision per Monad block on the Kuru MON-USDC market.
• dzhng/jevgrep (2,715 stars): a command-line tool for coding agents that finds code by asking what it does.
• realZachi/pg-jev (1,174 stars): a PostgreSQL extension for asking your tables questions in plain language.
• kerpopule/hermes-jev-skills (1,122 stars): Jev-powered routing, memory and compaction for Hermes agents, also usable with Claude Code and Codex.
• AgriciDaniel/jev-seo (643 stars): a live SEO audit of any site from its homepage URL, judged by Jev.
• fazlerocks/jevmail (99 stars): open-source Gmail triage that sorts mail into five categories, read-only and run locally.

• Built with Jev: community projects

Several people keep curated lists. They are independent, they change daily, and their own descriptions are the best summary:

• yibie/awesome-jev (2,354 stars): a curated list of public projects, integrations and discussions built on Jev.
• heyjunpenn/awesome-jev (964 stars): describes itself as a verified catalogue of 981 open-source projects built with Jev.
• AbdelStark/awesome-typesafe-jev (592 stars): a field guide with SDKs, live demos, agent tools and independent evaluations.

Yes, and several are popular. Laya (33,032 stars, Apache-2.0) is the most-starred, followed by SemIf (4,829 stars, MIT), Nokia Applied Research's AnyJev (1,277 stars, Apache-2.0), Strands Decider (643 stars, Apache-2.0) and Featherless's simple-jev (606 stars, Apache-2.0). They answer the same kinds of question, but they are different models, and none has been shown to match Jev on the same data.

• Jev vs Laya
• Jev vs open models

Stars are a sign of attention, not of quality or safety. A few checks take a minute:

• Licence. Look for MIT or Apache-2.0 if you want to reuse the code. A repository with no licence has no permission to reuse.
• Last update. Many projects appeared in the first weeks after launch and were not touched again.
• Which Jev version it uses. Jev 1.14 arrived on 14 October, and an older project may assume 1.13.
• What it does with your key. Read the code that handles your API key before you run it, and keep the key out of anything that runs in a browser.

• Can you use Jev for free?
• How to use Jev in Claude Code, Codex and OpenCode

Our read: if you want to build with Jev, start with TypeSafe's own SDK and skill, then read one or two community projects close to your use case, and use the lists to browse the rest. The number of projects shows how quickly developers adopted Jev, but the useful ones are the few that are maintained and well documented.
