Best SaaS starter for solo founders: boilerplate you own, or platform you call
Every "best SaaS starter" roundup compares boilerplates against each other. Here is when a fork-and-own kit is the right pick for a solo founder, and when a hosted SDK is.
In short
Boilerplates like ShipFast and MakerKit hand a solo founder code to own and maintain forever. A hosted SDK trades that ownership for zero ongoing integration upkeep. The right pick depends on whether solo means you want full control, or you never want to touch auth again.
Type "best SaaS starter for solo founders" into Google and every result compares the same handful of boilerplates against each other: ShipFast, MakerKit, Supastarter, TurboStarter. Different feature checkboxes, same starting assumption - a starter kit means a repo you fork. Nobody asks who keeps that repo's auth and billing integrations working eighteen months in, when there is still only one of you - the same buy-vs-build question that runs across every module a SaaS needs, just framed here as a whole starter kit instead of a single line item.
The one-paragraph answer
A boilerplate like MakerKit is still the right call if you want to own every line of code, plan to heavily customize or eventually flip the product, or are shipping something simple enough that you will never need per-tenant roles. A hosted SDK is the better call if "solo" specifically means you do not want a second job patching an auth library or a Stripe webhook every time one of them changes. BuildBase is built for that second answer. Auth, workspaces, RBAC and billing already run as a service, starting at $49 a month with a 7-day trial that does not ask for a card.
Where each fits
MakerKit, ShipFast and Supastarter are the boilerplate field. Buy one and you get a GitHub repo already wired to a database, an auth library and Stripe, plus, in MakerKit's case, B2B multi-tenancy in the kit itself: workspaces, email invitations and role-based access for products that need per-organization accounts. The code is yours outright.
So is every future decision about it. The day the auth library ships a breaking change, or Stripe deprecates a webhook version, that pull request has your name on it. There is no vendor behind the fork to write it for you.
BuildBase is the opposite trade. Twenty modules, including workspaces and role-based access, run as a hosted service behind one SDK. You never see the code that handles a Stripe webhook or a magic-link email, which means you also never patch it. What you give up is the boilerplate's biggest asset: if BuildBase disappeared tomorrow, your app would stop working. A forked repo has no such dependency on anyone.
| Feature | BuildBase | MakerKit |
|---|---|---|
| What it is | 20 modules on one hosted instance: auth, workspaces, RBAC, billing, workflows | A Next.js boilerplate repo you fork and deploy yourself |
| Code ownership | You call the SDK; BuildBase operates the service behind it | You own every file, including the auth and billing wiring |
| Ongoing maintenance | Integration patches and security updates are ours to ship | Yours - the next auth CVE or Stripe API bump is your pull request |
| Multi-tenancy and roles | Workspaces plus org- and workspace-level roles, built in | MakerKit ships workspaces, invitations and RBAC in every tier. Not universal across the category - check before you buy |
| Pricing | Launch $49/mo, no free plan, 7-day trial with no card required | One-time: $349 Pro or $649 Teams (up to 5 collaborators), lifetime updates |
| Infrastructure | Hosted by default, or self-hosted on the same SDK | Your infrastructure, your choice of provider from day one |
Where MakerKit wins
Three things a boilerplate genuinely does better, and none of them are close calls.
Full ownership. The repo is yours, including the auth and billing code most SDKs hide behind an API call. Read it, fork it, rip out the parts you do not need. Nothing we run sits in the path of your login screen, and nothing about your product depends on us staying in business.
No recurring platform fee. Past the one-time purchase, you are not paying a monthly charge for the wiring itself. You still pay Stripe, your database and your host directly, but there is no SDK subscription stacked on top of them.
Infrastructure freedom from day one. You pick the database, the host and the framework version. Nothing about the code assumes a specific vendor behind it, because there is no vendor behind it.
When the boilerplate is still the right call
Buy MakerKit, ShipFast or Supastarter if the code is close to the product itself and you want to keep making the decisions about how auth or billing actually work. Planning to sell the codebase later? Same call - a buyer wants a repo, not an account on someone else's platform. And if the product is a simple, single-user app with no organizations or team seats in its future, a lighter boilerplate is less machinery than workspaces and RBAC you will never touch.
None of that changes once revenue shows up. A boilerplate does not get more expensive to own as the product grows - it gets more expensive to maintain, and that cost is time, not a bigger invoice. What building auth yourself actually costs in hours puts a number on the maintenance side of that trade, and the full ShipFast comparison works through the exact one-time-versus-subscription arithmetic for one specific kit.
Which one to pick
Pick a boilerplate if ownership, resale value, or a genuinely simple product are the actual priorities - the field is real and MakerKit ships B2B workspaces and roles in the kit itself, so it is worth a look if you expect organizations later. Pick a hosted SDK if the honest answer to "what do you want to be doing in eighteen months" is your product, not a patched dependency tree.
A note on sourcing: MakerKit's prices and stack come from makerkit.dev and its pricing page, verified 6 September 2026 - $349 Pro and $649 Teams, one-time with lifetime updates, on Next.js, React Router and TanStack Start.
