Bolt.new Review: The Most Complete Free Full-Stack Offer in AI App Building
This is a research-based review. We have not tested this tool hands-on; every fact below comes from the vendor’s published pricing/docs and independent reporting. Prices checked October 2026.
The short answer: Bolt.new gives you a full-stack app builder with database and hosting included on a genuinely usable free tier — 1M tokens a month, no credit card, private projects included. The catch is the token model: as your project grows, each prompt burns more tokens, so learn to work small and export early.
What Bolt.new is
Bolt.new, from StackBlitz, is a browser-based AI full-stack app builder. You prompt it, and it scaffolds frontend, backend, and database in one chat — and the app actually runs in your browser, thanks to StackBlitz’s WebContainers technology, with no local setup. One click deploys it to hosting.
It’s the 0-to-1 machine of this batch: the tool you reach for when you want to go from “what if there was an app that…” to a live URL in an afternoon.
Under the hood, the WebContainers runtime is what makes Bolt feel different from prompt-to-code generators. Because your app actually executes in the browser — with a real file system, real npm installs, and a real dev server — what you preview is what you get. There’s no “it worked in the demo but broke on deploy” gap, because the preview is the running app.
What’s actually free
| Feature | Free ($0, no credit card) |
|---|---|
| Tokens | 1M per month, 300K daily cap |
| Website hosting | Included (Bolt branding) |
| Database | Included |
| File uploads | 10MB |
| Project visibility | Public AND private |
| Custom domains | No |
Paid: Pro at $25/month (10M tokens/month, no daily cap, unused tokens roll over one month, custom domains, no branding). Important mechanics: Bolt meters tokens, not prompts — every message syncs your project’s files to the AI, so bigger projects burn more tokens per message. Builders report 500K–1M tokens per prompt on large projects, and free tokens expire (no rollover).
Key features
- Full-stack generation in one chat: frontend, backend, and database scaffolded together from a single prompt thread.
- In-browser runtime: the app runs live in your browser via WebContainers — zero setup, zero installs.
- Integrations: Supabase, Stripe, GitHub, Netlify, and Figma, plus npm package support.
- One-click deployment: prompt, preview, deploy — the loop is tight.
- Prompt history as documentation: because the whole build happens in a chat thread, your conversation doubles as a log of every decision — handy when you come back to a project weeks later.
Pros and cons
Strengths
- The most complete free full-stack offer here — database and hosting included at $0.
- Private projects even on the free tier, which neither Lovable nor Replit match.
- 1M monthly tokens is genuinely usable for real side projects.
- No credit card required to start.
Weaknesses
- The 300K daily cap can stop a productive session cold mid-afternoon.
- Token burn grows as your project grows — success literally gets more expensive.
- Free tokens expire with no rollover, so you can’t bank them.
- Optimized for the 0-to-1 phase; it’s a prototyping tool, not a scaling platform for real traffic.
Who it’s best for
Bolt.new is best for side projects, prototypes, and anyone learning full-stack concepts without wrestling with setup. Indie hackers and weekend builders get the most from it. If you want a more traditional IDE experience and to learn real code as you go, Replit is the better classroom; if you want backend-included simplicity over token mechanics, Lovable is the gentler ride.
FAQ
Is Bolt.new really free?
Yes — 1M tokens per month with a 300K daily cap, no credit card required, with hosting and a database included.
How far does 1M tokens go?
Plenty for small projects. But note the scaling mechanic: a large project can burn 500K–1M tokens per prompt, so keep projects small or move to paid before they sprawl.
Can I use a custom domain on the free plan?
No — custom domains require Pro at $25/month.
What happens to my code?
Export it via the GitHub integration — your code isn’t locked inside Bolt.
How do I avoid burning all my tokens?
Keep projects small and focused, batch your requests into fewer, bigger prompts instead of many tiny ones, and export to GitHub before the project sprawls. Every message re-syncs your project files to the AI, so discipline about scope is literally money.
Bottom line
Bolt.new’s free tier is the real deal: database, hosting, and private projects for $0 is unmatched in this batch. The token mechanics demand respect — work in small chunks, watch the daily cap, and export via GitHub before your project gets big enough to burn 1M tokens a prompt. Used that way, it’s the best free prototyping budget in AI app building right now.
If you outgrow the free tier, Pro at $25/month is a natural next step rather than a cliff: 10M tokens, no daily cap, and one month of rollover turn Bolt from a weekend toy into something you can build a side business on — custom domain and no branding included.
