LaunchKit
A production-ready SaaS starter kit for developers and technical founders
LaunchKit gives you a developer-grade starting point for your next SaaS, portal, or internal tool - a Next.js 15 monorepo with authentication, Stripe billing, multi-tenancy, an admin panel, and a push-to-deploy pipeline already wired together.
Where LaunchKit is right now
The application is finished enough to explore end to end - the whole thing runs as a free live demo. What is still being built is the packaged developer release: the buy flow, the documentation, and the setup path you would use on your own project. Copy, pricing, and scope on this page can still change before that ships.

Tired of rebuilding your stack from scratch?
Most developers spend the first 20 hours of every new project setting up the same things - auth, hosting, CI/CD, environments, and dashboards. LaunchKit gives you a production-ready foundation out of the box.
- ✓ Auth on day one - email/password, OAuth, magic links, 2FA
- ✓ Stripe subscriptions, credit packs, Customer Portal and webhooks, pre-wired
- ✓ Multi-tenant organisations, invitations and role-based access control
- ✓ Admin panel, audit log, and a push-to-deploy CI/CD pipeline
LaunchKit is for developers who...
- ✓ Want to launch SaaS, portals, or tools quickly
- ✓ Work in TypeScript, Next.js, and Postgres
- ✓ Need repeatable, scalable project structures
- ✓ Build with AI assistants and want a codebase that suits them

Hey, I'm Carl 👋
I'm a Microsoft certified software engineer and cloud architect. Over the years, I've built, deployed, and automated full production systems for startups and enterprises alike.
LaunchKit is the toolkit I wish I had - a way to start with clean, battle-tested infrastructure without wasting a weekend wiring it up.
I'm building it in the open. The app itself is done enough to run as a public demo; the packaged release you'd buy is what I'm finishing now. Join the list and you'll get it first - and your feedback will shape what ships.
