JudtBeta

ChatGPT has sites. Your agent can have it too.

Judt is where agents build, publish and run Apps and websites, from the first file to a live address. Your agent does the work through our API. We run everything under it.

    Make an applicant tracker for Acme: a form for candidates and a board for the team.

No App yetWaiting

The App appears here

Every App, batteries included.

Each App has its own infrastructure so you can accomplish big things. Your agent controls it all over MCP or API.

export default {fetch(req, env)}acme-hiring.judt.dev
  1. Addressacme-hiring.judt.dev, or your own domain
  2. CodeYour pages, API routes and agent code
  3. DatabaseSQLite, migrated on each deploy
  4. StorageFiles, uploads and images
  5. Durable ObjectsState, live connections and alarms
  6. Schedules and queuesCron jobs, background work and workflows

Made for agents to use.

Judt is fully headless, designed to be used by agents. Sure, you can use the dashboard too, but we don't expect you to.

One API for every step

Create, write, preview, publish and restore an earlier version. Connect with MCP or the API, and soon the CLI.

PublishLive at acme-hiring.judt.dev
POST /api/apps/{id}/deployments
200 OK
{
  "id": "dep_8Hq2…",
  "status": "succeeded",
  "published_at": "2026-10-28T09:22:41Z"
}

Errors it can fix

If something fails, your agent gets the context to fix it. Or it can query logs to see and fix issues.

The preview didn’t buildCould not resolve “hono/jsx” from src/index.tsx

POST /api/apps/{id}/preview
422 Unprocessable Content
{
  "error": {
    "code": "preview_failed",
    "message": "The App's dev server failed to build or start",
    "detail": "Could not resolve \"hono/jsx\"…"
  }
}

Logs from every run

Requests, console output and crashes, from the preview and the live App.

Skills baked in
Skills that are ready to go
Secure hosting
We run your App on our own infrastructure, with TLS and DDoS protection.
Your model or ours
Bring your own agent and tokens, or hand the whole task to ours.

Start from a working App.

A template gives your agent an App that already runs. It spends its tokens on what makes your App different, not on sign-in pages and database setup.

Fewer tokens
Changing a working App costs less than writing one from an empty folder.
Best practices built in

Each one is an App like any other, with its own code, database, Secrets and address. Your agent builds it with the same API.
