Aaly vs Lovable
Lovable turns a prompt into a working full-stack web app, then lets you keep editing it by chatting. Frontend, database, auth and hosting all come from the one tool, with Supabase as the backend underneath. Work is paid for in credits, which Lovable's own pricing page calls units it uses to measure and pay for usage across your workspace, covering building apps, running deployed apps and AI features from a single balance.
Choose Lovable instead if
- ·You want one tool that produces the whole product, frontend included. Aaly has no UI builder, no design step, and does not host your app.
- ·You do not have a coding agent and do not want one. Lovable includes the AI; Aaly assumes you bring your own.
- ·You want prompt to live URL without opening a terminal. That is genuinely what Lovable is for, and Aaly plus an agent is more setup.
- ·The app is a prototype or an internal one-off, where a backend outliving the prototype is not the point.
Where Aaly differs
- →Aaly sells no AI, so nothing you do to your data model is metered by us. You connect the agent you already pay for, and the cost of changing the schema does not move.
- →Lovable's backend is Supabase, so multi-tenant isolation is row-level security that you or the AI has to write correctly on every table. Aaly applies tenant scoping below the API, with no policy to author. The Supabase comparison covers that argument in full.
- →The two compose. Lovable can call an external REST API, so building the interface there and pointing it at an Aaly backend is a real option rather than a rhetorical one.
| Lovable | Aaly | |
|---|---|---|
| What it produces | The whole app: UI, backend, hosting | The backend only |
| Who writes it | Lovable's own AI, included | The coding agent you already pay for |
| AI usage meter | Credits, from one shared balance | None. Aaly does not sell AI |
| Backend underneath | Supabase | Aaly's own definition-driven API |
| Multi-tenancy | RLS policies, per table | A project flag, enforced every request |
| Billed on | Credits consumed | Requests, projects, tenants |
| Cost of the tenth change | More credits than the first | Unmetered by Aaly |
The difference that compounds
No AI credits, because Aaly doesn't sell AI.
Lovable includes the AI, which is genuinely convenient, and prices it the way every tool in this category has to: by metering how much model work you consume. That meter sits on the one activity a product never stops doing, which is changing.
Aaly runs no model on your behalf. You connect the coding agent you already pay for, it writes a definition through MCP, and Aaly serves the API from it. There is no credit balance, no token count and no effort tier, because there is nothing here to meter.
What each one meters
Lovable
Credits, from one balance covering builds, deploys and AI features
Bolt
Tokens, most of them spent syncing your files to the model
Replit
Effort-based, then pay-as-you-go once the included amount is spent
Emergent
Credits, priced per AI action, more for bigger changes
What Aaly meters
Requests and events
What your app and your agents actually call. A fixed ceiling per band, so traffic alone cannot grow the bill.
Projects and tenants
How many backends you run, and how many customers are in them.
Not AI usage. Not seats.
Rewriting your whole data model ten times moves none of these numbers.
To be clear about what this does and does not mean: your coding agent still costs whatever it costs, and it may have its own usage limits. That does not change. What changes is that Aaly adds no second, AI-metered subscription on top of it just to have a backend.
