One door for small software.
Put an app online with one command, or let Claude Code, Codex or Cursor do it. It stays private behind sign-in, you share it by email, and every request is checked at our edge before your app sees it.
Point it at the folder your app is in. It works out how to build and run it, then gives it a private web address. No setup files, and no servers to look after.
$ jiayang deploy northwind/hello --create a Worker because it has index.js Version 1 (4e1f0c9a7b32) is live. https://hello--northwind.jiayang-apps.cloud
Add people by email and the app shows up in their list. Remove someone and they lose access within a minute, even in tabs they already have open.
$ jiayang share northwind/hello lena@northwind.dev lena@northwind.dev can now use northwind/hello as a viewer.
Nobody reaches your app without passing us first. We check who they are, then hand your app a signed pass with their name on it, good for 60 seconds.
Your app checks our signature on every pass. We strip anything a visitor adds to pose as someone else.
If a setting is missing or a check can’t finish, the answer is no. We never guess.
Keys for other services stay with us. We add them to your app’s outgoing requests.
No other workspace can reach your data, secrets or logs. We test that on every change.
Every request let in or refused is logged, and every change with who made it. Watch it live or look back later.
Claude Code, Codex and Cursor can put the app they wrote online through jiayang mcp, check it answers, share it and set its secrets. The agent works with your permissions, and what it does shows in the audit log under your name.
Set it up in Claude Code, Codex or Cursor.
One line in your app tells it who is signed in. Our libraries for Node, Python, Go and Rust check the pass for you.
import { requireUser } from "@jiayang-cloud/sdk"; export default { async fetch(request, env) { const user = await requireUser(request, env); return new Response(`hello ${user.email}`); }, };
Every Worker app gets a database of its own, with a SQL console in the dashboard. No other app can reach it.
Upload a folder or a .zip in the dashboard. No terminal needed.
Try a version at its own address, behind the same sign-in, then make it live.
We call a path on your app on a cron schedule, signed like any visit.
Deploy an MCP server, and Claude or Cursor connect as the people you share it with.
Your identity provider signs people in, and SCIM adds and removes them. An Enterprise feature, included on Business for early customers for a limited time.
Bring an app from Vercel, Netlify, Replit, Lovable, Bolt or v0 with its variables, keys and scheduled jobs.
Each deploy is checked for keys left in the code and packages with known vulnerabilities, on every plan.
