PromptFloe and Bolt.new both turn a text prompt into a working web app in minutes. The real difference shows up on your second week - when you're iterating on a real project and watching the bill.
Bolt.new is one of the fastest ways to get from a prompt to a running app, and its browser-based environment is genuinely good for rapid prototyping. The catch is its token-based pricing: tokens are consumed as the AI reads and re-syncs your project files, so the more your codebase grows, the faster you burn through them - and your monthly cost gets hard to predict.
PromptFloe takes the opposite approach: a flat, predictable monthly price, and a generation pipeline built so that iterating on one part of your app doesn't silently break imports somewhere else. If predictable cost and reliable iteration matter more to you than a built-in IDE, PromptFloe is the better fit. If you want a browser IDE and don't mind variable billing, Bolt is a strong choice.
| Feature | PromptFloe | Bolt.new |
|---|---|---|
| Pricing model | Flat monthly | Token-based (usage-metered) |
| Entry paid price | $10/mo (Basic) | $20/mo (Pro) |
| Free tier | None (entry at $10) | 1M tokens/month |
| Cost predictability | ✓ Fixed | ✗ Scales with project size |
| Token rollover | N/A - flat pricing | ✓ Unused tokens roll over |
| Iteration cost | ✓ No additional cost | ✗ Each re-prompt consumes tokens |
| Best for | Predictable budgets, reliable iteration | Fast prototyping in browser IDE |
Bolt's token model means your cost rises with project complexity and with every debug cycle. Users consistently report that tokens "disappear quickly" as a project gets larger, and that budgeting on bigger builds is difficult.
PromptFloe charges a flat monthly fee ($10-$50). You know your bill at the start of the month, and it doesn't change because your app got bigger or because the AI had to make several attempts at a fix. For students and indie developers on a fixed budget, that predictability is often the deciding factor.
The most expensive moments in any AI builder are the ones where the tool breaks something and you have to spend more (more tokens, more prompts) getting it back. PromptFloe's iteration design specifically targets the cross-file import-contract problem - where editing one component leaves another file referencing something that no longer exists.
With Bolt's token model, the cost of those repair loops is real: every re-prompt on a larger codebase consumes more tokens. The faster and more reliably you reach a working state, the less you spend.
Tokens are tied to your subscription. Bolt's Pro plan ($20/mo) includes 13M tokens/month. Additional tokens cannot be purchased; you upgrade plans. May 2026 price was $25, now $20.
Yes. Edit an app as many times as you want without additional cost. PromptFloe uses diff-based patching so edits preserve your code context and don't require full regeneration.
You can't build until the next billing cycle. PromptFloe lets you buy 100K-token packs at ₹49 ($0.60 USD) - no interruption, no forced upgrade.
Both platforms allow downgrade. PromptFloe takes effect immediately at cycle end. Bolt allows mid-cycle downgrade with proportional credit adjustment.
