About

What Superslate is

Superslate is a source-owned SaaS foundation: a Bun + Hono API, a React 19 SPA, API contracts for full type safety from shared Zod schemas, Better Auth authentication, provider-neutral billing with Polar, Stripe, and Dodo adapters, and transactional email. You buy it once, clone it, and ship your own product from it. There is no subscription and no runtime dependency on us.

We specialize in making a codebase that gives coding agents explicit repository context and runnable checks. That capability ships as inspectable artifacts: scoped AGENTS.md architecture contracts, maintained golden-path guides for common changes, a machine-readable navigation contract, a six-tool local context server, and an outcome evaluation harness. The features are laid out on the home page, and the live demo runs the same image the scaffold produces.

Who it is for

We build for experienced TypeScript founders and small teams who already use coding agents and want to own a coherent, tested foundation instead of assembling and re-debugging auth, billing, email, and deployment themselves. One deliberate stack, one price, everything included. See pricing and the FAQ for what each tier covers.

Who builds it

Superslate is built and sold by Supercollective, a software studio in Bengaluru, India. Polar Software Inc. is the merchant of record for checkout, payment, and tax; the licence itself is between Supercollective and you, as set out in the license.
