Front end, back end, and the Supabase dependency
It generates the interface, routing and state, and the backend pieces an application actually needs: a database, authentication, file storage.
It does that through Supabase rather than inventing its own layer, which is both a strength and a commitment. The strength is that you end up with a conventional, well-documented stack rather than a proprietary one, and everything you learn transfers. The commitment is that Supabase is a second service to configure, to understand, and eventually to pay for.
Anything involving data, users or uploads requires it. Budget for that from the start rather than discovering it when the prototype needs a login.
The generated security rules, which need a real review
This deserves its own section because it is where AI-generated applications most often fail, and the failure is not visible from the interface.
Supabase uses row-level security — database policies deciding which rows a given user may read or write. Get them right and the application is sound. Get them wrong and any authenticated user can read every other user’s data, while the application looks and behaves perfectly.
Generated policies are plausible and are not a substitute for someone checking them. Before real user data goes anywhere near it, have someone who understands RLS read the policies. If nobody on the project can, that is the moment to bring someone in, not after launch.
The same applies to what the front end can call directly and which keys are exposed to the browser. These are standard mistakes with standard fixes; the problem is that nothing prompts you to look.
Building from a design
Iteration is conversational, and it can also work from an image — supply a design and it builds toward it.
That is more useful than it sounds for the audience this tool serves. A founder with a Figma mockup or even a screenshot of something they like can get considerably closer to it here than by describing it in words, and design fidelity is the whole reason to pick Lovable over its competitor.
GitHub sync, and why it matters more than the generation
Projects sync to GitHub, so the code is genuinely yours and can move to a normal development workflow when the prototype outgrows the tool.
This is the most important feature for anyone whose project might succeed, and it is worth turning on immediately rather than eventually. With sync in place, Lovable is a fast starting point. Without it, it is a platform you are stuck on, and the difference only becomes visible at the moment you most need to move.
Credit mechanics, and the debugging trap
- A browser and an account. Credit-based pricing with a free allowance; sustained work needs a paid plan.
- A Supabase project for anything involving data, authentication or storage — a second service and eventually a second bill.
- Enough technical literacy to connect those services and understand what has been generated.
- Review capability, or access to someone with it, before the application handles real user data.
The credit pattern mirrors Bolt’s: generation is affordable, and fixing a generated problem is where credits disappear. Each correction round re-reads context, and a stubborn issue can cost more than the original build while leaving you with a half-working application you cannot abandon.
Where the ceiling is
Conversational iteration is fast up to a point and slow past it. Somewhere around the third or fourth interlocking feature, describing a change becomes harder than making it, and the tool starts undoing things you asked for earlier.
That is the signal to move to GitHub and a real editor. Recognising it early is the difference between a good experience and a frustrating one, and the tool will not tell you — it will keep trying.
Who gets real value
Founders needing something demonstrable for a pitch, a landing-page test or a first cohort of users, where credibility of appearance is part of the point.
Product managers and designers building something clickable without an engineering queue.
Developers scaffolding an internal tool that is standard CRUD over a database — real work, no interest in writing it again.
It is a weak fit for teams with an existing codebase, for non-JavaScript stacks, for unusual architectural requirements, and for anything handling sensitive data without review capacity.
What justifies the credits
- Output that looks finished — the strongest practical reason to choose it.
- A real backend with authentication and a database, not a mock.
- GitHub sync, so there is a genuine exit path.
- Design input, building toward an image you supply.
- A conventional stack that transfers to normal development.
- Hours instead of a week for a working prototype.
What to watch
- Credits drain fastest while debugging, exactly when you cannot stop.
- Supabase is effectively mandatory, adding a dependency and a bill.
- Generated security rules need a human review — the highest-consequence item on this page.
- Complexity has a ceiling past which conversation is slower than code.
- One stack. React and Supabase, or a different tool.
- Design polish can flatter weak foundations, which makes the review easier to skip.
Taking the project with you
With GitHub sync enabled, you leave with a working repository and a Supabase project you own. That is a genuinely clean exit and better than most platform tools offer.
Enable it on day one. The exit is only clean if you set it up before you need it.
Comparable builders
- Bolt.new — the direct competitor; faster to running, less polished, no mandatory backend service.
- Replit — hosts and runs everything, not restricted to JavaScript.
- v0 by Vercel — interfaces only, for a project you already have.
- Cursor IDE — where the project should move once it is real.
