Oh, hi! I'm Ray, the stingray who lives inside Fabricator.
Building a Rayfin app usually means juggling CLIs, Copilot, git and a browser… whoa. The room is spinning.
Fabricator puts it all in one window.
Name your app, then describe what you want, in plain English. Fabricator's agent writes the code… and I cheer!
Deploy it, and I'll swim it over to Microsoft Fabric. Hey, that's me! Fins crossed.
And Rayfin gives your app the backend it needs, automatically: database, APIs, auth, storage, functions and hosting. Scalable, governed, and inside your organization's boundary. You didn't lift a fin.
Your app runs live, right next to the chat. See something to change? Point at it in Design, and ask.
After every successful chat turn, Fabricator redeploys your app. It's live! Then share it with people in your organization.
The Advisor grades your app's health. Blueprint maps how it all connects. And if something breaks, I'll dig through the logs with you.
It runs on the GitHub Copilot account you already have. Download Fabricator, and come say hi!
Psst… a group of stingrays is called a fever. I'm not making that up.
How it works
The build loop stays in one desktop window: chat, preview, deploy, then keep improving.
Describe it
Tell Fabricator what to change. Fabricator’s agent, powered by GitHub Copilot, edits the project and shows its work log, diffs and decisions as it goes.
