Jev repos blowing up right now. I made a list of the repos people are using to build with jev. 👇

Jon Kraayenbrink posted the eleven Jev repositories climbing GitHub fastest: a generative UI framework, a browser agent, a Claude Code compaction plugin, a trading bot, a desktop controller, a code reviewer, a Mario player, two MCP servers, a Codex model router, and the awesome list that tracks the rest. Every one of them is on this site with its own page, so the list below goes to the write-ups rather than straight back to GitHub.

The eleven have one shape in common. Each replaced a question that had a fixed, enumerable answer — which element to click, which model to route to, which line to cut, which controller button to press — with a typed Jev call, and left the prose to a language model or to no model at all. That is why the list skews to plugins, routers and agents rather than to products: the work of the last week has been people finding the repeated decision inside a tool they already use and pulling it out.

Star counts are the honest caveat. The numbers on this page are read from the GitHub API on the date printed with them, and the fast movers here gained thousands in days, so they are a snapshot and not a ranking that holds. jev-ultrafast, fast-jev-compaction, jev-trader, jev-review, typesafe-mario, jev-mcp, typesafe-mcp and jev-codex-router were all created within days of the Jev launch; json-render and agent-desktop are older projects that added a Jev path.

Two names in the list are not builds in the same sense. json-render is Vercel Labs' generative UI framework, where the Jev composer sits behind an experimental flag rather than carrying the project. awesome-jev is a list, not a program — the companion index to this directory.

The 11 repositories, in the order the post names them

  1. 1. json-render

    18,675 stars · TypeScript

    Vercel Labs' generative UI framework: a model returns a JSON spec and your own components render it, with an experimental Jev composer behind a flag.

    vercel-labs/json-render
  2. 2. jev-ultrafast

    22,977 stars · Python

    Browser Use's browser agent with the step decision — which element to act on next — replaced by one Jev call.

    browser-use/jev-ultrafast
  3. 3. awesome-jev

    189 stars

    The companion list to this site: use cases, projects, SDKs, tools and learning resources, with pricing, limits and a quick start.

    kraayenjon/awesome-jev
  4. 4. fast-jev-compaction

    7,638 stars · TypeScript

    Claude Code context compaction that deletes the turns Jev scores as spent instead of summarising them.

    tamaratran/fast-jev-compaction
  5. 5. jev-trader

    2,997 stars · TypeScript

    A trading bot that takes one Jev decision per 300 ms block and places the order.

    jarrodwatts/jev-trader
  6. 6. agent-desktop

    1,795 stars · Rust

    Desktop control read from the accessibility tree rather than screenshots, with Jev picking the operation.

    lahfir/agent-desktop
  7. 7. jev-review

    686 stars · TypeScript

    A staged code-review workflow that scores a diff with Jev and shows the result on a local dashboard.

    devagrawal09/jev-review
  8. 8. typesafe-mario

    449 stars · Python

    Jev picks NES controller inputs from game telemetry, never from pixels.

    fhshaik/typesafe-mario
  9. 9. jev-mcp

    530 stars · JavaScript

    An MCP server that hands an agent Jev judgment tools: claim checks, screening and ranking.

    jkudish/jev-mcp
  10. An MCP connector in Go that gives any agent direct access to Jev.

    itsmostafa/typesafe-mcp
  11. 11. jev-codex-router

    274 stars · JavaScript

    Jev picks the model and the thinking effort for every Codex turn, before the turn runs.

56.2k stars across 10 of the 11, read from the GitHub API on Oct 15, 2026. These move daily — quote them with the date.
