FastSaaS Review (2026)
We keep structured data on 66 starter kits. Below is how FastSaaS measures up on features, pricing, and stack, including the cases where a different kit would serve you better.
Verdict
On raw coverage FastSaaS does well: 10 integrations against a catalog average of 8, putting it among the top kit for FastAPI by that measure. At $92 the decision comes down to whether the included Admin Panel, Auth and Billing 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. The main caveat remains the missing Components.
What Is FastSaaS?
FastSaaS is a Python SaaS boilerplate built on FastAPI and PostgreSQL. It includes email and Google OAuth sign-in, Stripe subscriptions, multi-tenant teams, user management and an admin panel. Docker setups, CI/CD pipelines and Sentry error tracking are ready to go, so you can deploy a production backend without wiring the basics yourself.
FastSaaS Tech Stack
FastSaaS uses FastAPI, Python, PostgreSQL and Docker. Only 2 kits in our catalog use FastAPI, so your options in this stack are comparatively limited.
What's Included in FastSaaS
FastSaaS lists 10 integrations: Admin Panel, Auth, Billing, CI/CD and Deployment and 5 more. That is above the catalog average of 8 integrations per kit. Worth knowing before you buy: Components is commonly included in comparable kits but not listed for FastSaaS. If you need it, budget the integration time yourself or look at the alternatives page.
FastSaaS Pricing
FastSaaS starts at $92 and goes up to $463. That sits below the catalog median of $149. 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 FastSaaS
The honest answer depends on what you are building. FastSaaS makes sense if you are starting a new project on FastAPI and the included integrations match your requirements list. Since authentication and payments are both wired up, FastSaaS covers the two integrations that consume the most setup time in a typical SaaS build. Skip it if Components is hard requirements for you; comparable kits include it already.
