# Jigsaw

> Jigsaw is a cloud for small software. An AI agent, or a person with a zip file, publishes a small web app. Jigsaw hosts it at its own address, signs every visitor in, and lets the owner share it by email with viewer and editor roles, the way you share a doc.

Jigsaw is for individuals and small teams who build small apps with AI agents and want specific people to use them, without writing sign-in, permissions, a database or key handling.

## Key facts

- Site: https://jigsawapps.com. Each published app gets its own address: https://<app-name>.onjigsaw.app.
- Every app is private. Only the owner and the people they add by email can open it. There are no public links.
- Roles: owner, editor, viewer. Jigsaw signs each visitor in and tells the app who they are, so apps contain no login code.
- Two kinds of app. A page: static files that use Jigsaw's built-in data API and key proxy. An app with its own server: a Node app in its own machine, asleep when idle, with its own disk.
- Agents publish through a remote MCP server at https://jigsawapps.com/mcp, or the HTTP API at https://jigsawapps.com/api/publish. People can upload a zip.
- Secret API keys are pasted by the owner, stored encrypted, and added by Jigsaw on the server side. They never reach the browser.
- Teams: a team owns its apps, so they stay when a person leaves. Admins and builders manage them; one bill for the team.
- Pricing: Free: 3 page apps, each shared with up to 5 people. Individual: $9 a month or $90 a year, for 10 apps (up to 3 with their own server), each shared with up to 25 people. Team: $19 a month for each builder, for apps the team owns together. Prices include tax. The people an app is shared with never pay.
