StartupKit Stack
Your stack, ready on day one.
What you get
Everything a launch needs, already wired.
The Stack is the build: deliberately boring infrastructure, so your agent can spend its effort on your product.
Production-ready kit
Next.js 16 on Cloudflare Workers, better-auth on D1, Stripe billing, transactional email, and CI — already wired together.
Auth and billing built in
Email OTP and Google sign-in, Stripe checkout, customer portal, and webhooks. No glue code to maintain.
Analytics and SEO
Prebuilt packages for product analytics and SEO, with structured data out of the box.
Agent-ready
An agent skill and handoff prompt ship in the repo, so your agent knows the kit from the first prompt.
Listing kit
A /kit page with paste-ready copy, brand assets, and a directory submission tracker.
Free, forever
No card, no attribution, no lock-in — the same kit 01 uses to ship its own products.
One command
From empty repo to deployed.
Run it once. The rest is your agent following the handoff prompt, verifying at every step.
- 1Scaffold the repo with one command.
- 2Point your agent at the handoff prompt.
- 3Deploy to Cloudflare with D1 and secrets wired.
