Loved by builders worldwide

From indie hackers to funded startups — everyone ships faster.

Shipped our MVP in 4 days. The auth + Stripe setup alone saved us two weeks of integration hell.

Every boilerplate I tried felt like a compromise. This one doesn't. TypeScript strict, clean architecture, zero cruft.

The AI streaming hooks are genuinely useful. Switch between OpenAI and Anthropic with one line change.

We've built 6 internal tools on this. The admin dashboard alone is worth 10x the price.

Docs are actually good. That alone puts it ahead of every competitor I've tried in the past year.

Went from zero to paying customers in 11 days. The billing portal worked perfectly out of the box.

I use this as the base for every client project. Cut my setup time from a week to under an hour.

Framer Motion animations are tasteful and fast — not the usual janky scroll effects you see everywhere.

Customized the design system in 30 minutes. CSS variables are a joy to work with.

Finally a SaaS kit that doesn't treat multi-tenancy as an afterthought. Our team management works flawlessly.
