Jigsaw
Jigsaw is a cloud for small software. When your agent has built a small web app, say "publish this to Jigsaw" and it goes live at its own address. Then you choose who can use it, the way you share a doc: type in each person's email address and make them a viewer or an editor. Send them the link; the first time they open it they sign in with that email, and they are in. What Jigsaw takes care of: - Hosting, at an address of the app's own. - Sign-in for every visitor. The app contains no login code. - Roles: owner, editor and viewer. - Shared data, through a built-in data API, so everyone with access sees the same lists. - Secret API keys. The owner pastes them into Jigsaw and they never reach the browser. - Apps that need their own server. Each runs in its own machine and sleeps when idle. Every app is private. Only the owner and the people they add by email can open it. There are no public links. Tools: Publish an app, Get an upload link (for agents that can run shell commands), List apps. Publish a small app. Share it like a doc.
