The best SaaS boilerplates for Claude Code
There is no single best one; there is a best one for how you work. Makerkit gives an agent the most tools, Supastarter the most frameworks, ShipFast the lowest price, and Jetpack the only machine-checkable definition of done an agent can run unattended. If you want the agent to finish without you watching, that last property is the one that decides it.
What actually makes a boilerplate agent-ready?
One property: whether the agent can tell that it finished. Rules files and MCP tools help an agent start; only a definition of done a machine can check lets it stop. Everything else — more tools, more docs, more examples — makes the agent faster at guessing.
That distinction is why “agent-ready” and “agent-adapted” are worth separating. An adapted kit hands your agent a longer instruction file. A ready one hands it a test it can run.
Which one should I pick?
Jetpack — best when you want the agent to finish without you watching
The only one of the four with a machine-checkable definition of done per feature. The agent scaffolds, migrates, tests and fixes until `pnpm accept <feature>` is green, then stops. Metered AI billing, cost caps and RAG are already wired and tested.
Makerkit — best when you want the widest tooling surface
Ships far more MCP tools than we do, a real documentation site, and mature multi-tenancy from the first commit. If your agent's problem is that it lacks tools rather than that it lacks a finish line, this is the stronger pick.
Supastarter — best when you need more than Next.js
Covers Nuxt and TanStack Start as well as Next, and five payment providers. Setup is Docker Compose and an hour or two rather than one command, which is a fair trade for the breadth.
ShipFast — best when price is the deciding factor
The cheapest and simplest of the four, and the fastest route to a landing page with Stripe checkout if you intend to write the application code yourself. It ships no tests, and states that purchases cannot be refunded.
How do I check a kit's claim myself?
Clone it, give your agent one feature to add, and walk away. Come back and ask what proves it works. If the answer is a passing command you can run yourself, the claim holds; if it is a summary the agent wrote about its own work, it does not.
