00/The founder's codebase

Ship your next SaaS
in a day, not a month.

Auth, payments, database, file storage, and admin panel pre-configured. Batman ships them already wired together — so you start on the part nobody else can build.

The Batman admin dashboard: an overview page with user and activity counts, onboarding and notification rates, recent users, recent notifications, a user-locations map and quick links.

01/See it running

Watch it go from nothing to a running app.

02/What's included

Everything you'd otherwise spend a month building.

01 / 08

Admin dashboard

Users, analytics, products, blog, notifications, feedback — one control panel for the whole app.

Browse and manage users, read analytics, edit products and blog posts, and work through feedback and notifications from a single place. It runs on the same auth and database layer as the rest of the app, so there is no second system to keep in sync.

Core of the boilerplate

06/FAQ

Questions people actually ask.

The full monorepo: a Next.js app with authentication, an admin dashboard, payments, file storage, a blog, notifications, and a guided setup wizard. Plus a license key for npx create-bb, which always pulls the latest release.

No. One payment, lifetime access, including future updates. Nothing recurring, nothing to cancel.

Yes — one license covers up to 3 projects, for yourself or for clients. You just can't resell the boilerplate itself.

You need to be comfortable running terminal commands. The Setup Wizard handles configuration through a UI, so there are no config files to hand-edit.

Choose Pay in ETB and check out with Telebirr, M-Pesa or CBE Birr through Jami. You get the same license key as card buyers.

Reply to your purchase email. You keep your license key, so you can re-download or upgrade at any time.
