We believe building software should feel like describing an idea, not writing code.
We are the team behind Mutter Labs — an AI app builder that turns a plain-English description into a real, running full-stack application.
We started Mutter Labs because we kept watching the same thing happen: someone has a genuinely good idea for an app — a booking system, a small CRM, a tool for their team — and then it just never gets built. Not because the idea was bad, but because turning it into working software takes weeks most people don't have and skills most people never needed to learn.
So we built Raina, our AI, to close that gap. You describe what you want in plain English — even just "hi, I want to rent out cars" is enough to start — and Raina designs the data model, builds the screens, wires up the logic, and hands you back a real application running live in your browser. No servers to configure, no local setup, nothing to install.
We think of Mutter Labs as a collaborator, not a code generator you talk to once. After the first build, you keep describing changes in plain language — "add a dark mode toggle," "add a late fee for overdue bookings" — and Raina remembers the whole conversation, even if you close the tab and come back another day.
Fast by default
Apps run instantly in a real Node runtime inside your browser tab — there's no server to wait on.
Built responsibly
We cap usage per person and moderate what gets built, so the platform stays fast, fair, and safe for everyone.
Made for ideas, not just code
We designed Mutter Labs for people with an idea worth building, whether or not they've ever written a line of code.
Have an idea? Let's build it.
Describe your app in plain English and Raina will have a working version ready in minutes.
