Aaly vs Bolt
Bolt (bolt.new, from StackBlitz) builds and runs full-stack web apps from a prompt, in the browser. Bolt Cloud added a managed database, auth, file storage, edge functions and hosting, so a Bolt app no longer has to leave the tool to go live. Usage is metered in tokens: the free plan carries 1M tokens a month with a 300K daily limit, and Pro at $25 a month starts at 10M tokens, with unused tokens rolling over for up to two months in total.
Choose Bolt instead if
- ·You want the app running in the browser seconds after the prompt, with no local setup at all. Bolt is unusually good at that and Aaly does not try to be.
- ·You want the frontend and the backend from one tool, and one bill.
- ·You are iterating on look and feel, where most of the work is UI and the data model is barely moving.
- ·You do not already pay for a coding agent, so bundled AI is a saving rather than a duplicate cost.
Where Aaly differs
- →Token metering means the price of a change tracks how much of your project the model has to read. Bolt's own FAQ notes that most token usage comes from syncing your project's file system to the AI. Aaly meters none of that, because Aaly is not the thing running the model.
- →A Bolt backend is generated code plus Bolt Cloud's services. An Aaly backend is a definition, so a schema change updates the contract rather than rewriting files that then need reviewing.
- →They compose. A Bolt frontend calling an Aaly REST API is a reasonable split: the tool that is best at producing a UI does that, and the backend stops being something the AI regenerates.
| Bolt | Aaly | |
|---|---|---|
| What it produces | The whole app, running in-browser | The backend only |
| Who writes it | Bolt's own AI, included | The coding agent you already pay for |
| AI usage meter | Tokens (1M free, 10M+ on Pro) | None. Aaly does not sell AI |
| What burns the meter | Largely syncing your files to the model | Nothing: no model runs here |
| Backend | Generated code plus Bolt Cloud | Served from a definition, no code |
| Multi-tenancy | Something you model yourself | On in every project by default |
| Billed on | Tokens consumed | Requests, projects, tenants |
The difference that compounds
No AI credits, because Aaly doesn't sell AI.
Bolt 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.
