Saas.js in 2026: A Review Based on Catalog Data
Saas.js is one of 66 boilerplates we track, and one of 32 built on NextJS. This review covers what it ships with, what it costs, and where it falls short, based on the structured listing data we maintain for every kit in the directory.
Verdict
Feature coverage is solid at 15 integrations (catalog average: 8). At $245 the decision comes down to whether the included 2FA, API and Auth map onto what your project actually needs. If they do, the price is a rounding error against the build time. If they don't, no boilerplate is a good deal.
What Is Saas.js?
Saas.js, formerly Saas UI, is a production-ready starter kit for B2B SaaS on TanStack Start, with a Next.js kit as well. It ships Better Auth with social login, magic links, 2FA, passkeys and SSO, workspaces with roles and invites, and Stripe billing that syncs your setup and handles tiered, metered and usage-based pricing. Data lives in PostgreSQL through Drizzle, the API is end-to-end typed with tRPC, the UI uses a Chakra UI theme with ready components, and transactional emails go through Resend or your own SMTP. Playwright, Vitest and GitHub Actions come set up, with strict types and consistent patterns that keep AI coding agents on track.
Saas.js Tech Stack
Saas.js uses NextJS, Better Auth, React and TypeScript. NextJS is one of the most common foundations in our catalog (32 kits use it), which means plenty of alternatives exist if Saas.js doesn't fit, but also that the ecosystem around this stack is well documented. The codebase is typed end to end, which matters more in a boilerplate than in your own code: you will be reading and modifying unfamiliar files, and types make that considerably safer.
What's Included in Saas.js
Saas.js lists 15 integrations: 2FA, API, Auth, Billing and CI/CD and 10 more. That is above the catalog average of 8 integrations per kit.
Saas.js Pricing
Saas.js starts at $245 and goes up to $949. That is above the catalog median of $147, so it needs to justify the premium through its feature set or the quality of its implementation. One-time pricing for a codebase is hard to evaluate in the abstract; the relevant comparison is your own hourly cost for the setup work it replaces.
Who Should Use Saas.js
Saas.js makes sense if you are starting a new project on NextJS and the included integrations match your requirements list. Since authentication and payments are both wired up, Saas.js covers the two integrations that consume the most setup time in a typical SaaS build. Skip it if you want full control over every dependency choice; a boilerplate is by definition a set of decisions someone else made for you.
Pros
- ✓ 15 integrations, above the catalog average of 8

- ✓ NextJS stack with a large ecosystem of comparable kits and documentation
Cons
- ✗ $245 is above the catalog median of $147
- ✗ Locked into the stack and architecture decisions the maker chose
