How to build a SaaS MVP without a developer

The hardest part of a SaaS MVP used to be finding someone to build it. A technical cofounder, a freelancer, an agency - each one is expensive, slow, or both, and none of them are guaranteed to ship. AI agents change that equation. Here is what building an MVP without a developer actually looks like.

Start with the smallest real version

An MVP is not a smaller version of everything you dream about, it is the one flow that proves people want it. A way to sign up, the single thing your product does, and a way to tell that it worked. Describe that in plain language and let the agents build it. Resist adding the rest until the core is real and online. If you are new to this, building a web app with AI walks through the basic loop.

Build, test, and ship it

You describe the flow, the agents write the code, and a separate agent runs the app to confirm the sign-up and the core action actually work before it reaches you. When it holds up, you publish to a public URL and put it in front of a few real people. No terminal, and the code sits in your own GitHub repo, so a developer can take over later if you raise money or outgrow it.

The point of an MVP is speed to a real answer. Doing it without a developer used to mean not doing it at all. Now it means describing the smallest version that matters and watching it come to life.
