Skip weeks of testing and setup. Go straight to your idea.
A booking app with team accounts and payments
We scaffold your apps. You keep building on your computer.
Every line is yours.
Built by the maintainer of battle-tested open-source infrastructure
You can building with a single command, the template is completely free.
One command scaffolds Backend, Frontend, Admin panel, a desktop build, a mobile app, and a browser extension. Code, CI, and local infrastructure already wired. Open source.
Get features like authentication, organizations, billing, teams, notifications and many more. Every line is yours to keep.
Same mental model as shadcn.
Hand your agent the MCP server and let it build the whole thing on its own.
One shared foundation. Already connected.
Not a developer? You can still build the whole thing.
The rules keep your agent inside conventions a professional team would recognize. The day you hand this to a real developer, they open a normal repo with types, tests, and lint rules. Nothing to untangle, nothing to rewrite.
Colors, radius, and type live in one token file. Every screen, chart, and email reads from it, so a rebrand is one commit.
Try it outEvery string is a typed Paraglide message, so a missing translation fails the build instead of shipping blank. Drop in a locale file and the app follows.
Everything goes live on your own host, with the URLs, secrets, and migrations already wired between the services. No dashboards, no YAML.

Every screen below ships in the repo. Auth, billing, teams, dashboards and settings, wired and yours to edit.
Every card is days or weeks of work you skip. UI, APIs, and admin panels, wired together and tested.
Pick the one that sounds like you.

The template is tuned so coding agents stay on the rails, land correct code faster, and burn fewer tokens doing it.
One ruleset. Every tool reads it.

Copilot

Rolldown, oxlint, and Lightning CSS, all written in Rust. Builds, lints, and typechecks land before you look away.
Then we stack features on top
Your agent reads the layout and the conventions before it writes a line. Correct code on the first try, not the third.

Rules for every corner of the stack
Backend routes flow straight into the frontend SDK. Rename a field and every broken call turns red in your editor, not in production.
const user = await sdk.users.getProfil()
Property 'getProfil' does not exist.
Did you mean 'getProfile'? Backend renamed it 4s ago.
