SaaS Boilerplate
If you've built more than one SaaS, you've rebuilt the same plumbing each time. A boilerplate packages it so you skip straight to the part that's unique to your product.
The first saas boilerplate are being listed. Explore the full marketplace in the meantime.

“Starter kit”, “boilerplate” and “complete SaaS” are not interchangeable. Select the closest outcome to get the appropriate evaluation path.
Recommended path
Start with an owned-code foundation when you want to choose the product logic, data model and interface yourself.
A listing should be judged against observable delivery evidence, not a feature-count headline. Missing evidence must remain “not documented” rather than being inferred.
| Gate | Minimum verifiable evidence |
|---|---|
| Reproducible build | Pinned runtime and package manager; clean install, typecheck and production build pass. |
| Configuration | Complete environment-variable example with secrets excluded and required services identified. |
| Database | Versioned schema and migrations, seed strategy and tenant-isolation model where applicable. |
| Authentication | Sign-up, sign-in, sign-out, recovery, callback and protected-route states tested. |
| Billing | Checkout, webhook signature, idempotency, failed payment, cancellation and entitlement behavior documented. |
| Quality | Critical flows tested; loading, empty, error, mobile, keyboard and reduced-motion states reviewed. |
| Operations | Deployment, logs, backups, upgrades, license, changelog and handover path documented. |
| Acquisition | Canonical metadata, sitemap, structured data, analytics events and consent requirements explicit. |
Compare candidates in the same environment: clean install, identical Node version, typecheck, production build, authentication and billing smoke tests, Lighthouse profile, dependency audit and documented setup time. Assetzaar will not publish a cross-kit benchmark until at least three current kits have been tested with that protocol and the raw conditions are disclosed.
Most quality boilerplates ship the same core building blocks:
Pick by stack fit and how much you'll customize. ShipFast is a fast single B2C kit; Makerkit and supastarter suit B2B teams that need multi-tenancy. A marketplace like Assetzaar lets you compare maintained options — and add landing pages or agent skills later — under one account.
| Option | Best for | Notes |
|---|---|---|
| ShipFast | One opinionated B2C kit, fast | Single Next.js kit; no multi-tenancy or admin panel. |
| Makerkit | B2B teams | Plugin architecture; free tier plus one-time Pro. |
| supastarter | Feature-dense B2B | Deep multi-tenancy with RLS; one-time tiers. |
| Assetzaar | Comparing kits + more product types | Marketplace: live previews, clear licenses, also agent skills & landing pages. |

FAQ
A SaaS boilerplate is a starter codebase with the common foundations of a software-as-a-service product already built — authentication, subscription billing, a database layer and usually a dashboard — so you begin from a working app instead of an empty project.
Usually yes if it's maintained and matches your stack — it removes weeks of wiring auth, billing and a dashboard. Verify the code is clean and the license covers your use before buying.
