About SaaS Apps
Building a SaaS product without a budget is realistic today, but it requires stitching together the right free tools instead of one all in one platform. These guides cover the specific combination that works: an AI builder for the interface, Supabase for the backend, and Vercel for hosting, plus the errors people hit connecting them.
The $0 stack that actually holds up
Lovable, Supabase, and Vercel together cover interface, backend, and hosting on free tiers that scale with real usage, which is why this combination shows up across most of these guides.
Where the free tier runs out
Free tiers are generous but not unlimited. These guides flag the specific limits, like database size or function invocations, that matter once you have real users, so you are not surprised later.
Can I really build a SaaS product for free?
Yes, for an early stage product. Lovable, Supabase, and Vercel all offer free tiers sufficient for a first version with real users, covered across these guides.
What is the biggest mistake people make building their first SaaS app?
Building the interface first and treating the database and authentication as an afterthought, which usually means redoing core parts of the app later.
