What Bolt.new does
Bolt.new is StackBlitz's browser-based AI tool that scaffolds, edits, and deploys full web applications from natural-language prompts, running entirely in-browser via WebContainers. Usage is metered in tokens with daily and monthly caps on the free tier and a rollover token pool on paid plans.
What you get: In-browser WebContainers runtime, Prompt-to-deploy, Token rollover, Custom domains.
Typical jobs: Rapid web prototyping; No-install client demos.
What users complain about: '30 mins in I was out of API credits. My prototype was burning API calls in ways I never imagined' (Hacker News (Show HN commenter))
Pricing and plan limits
Verified August 2026| Plan | Monthly | Annual (per mo) | Limits |
|---|---|---|---|
| Free | Free | n/a | 300K tokens/day, 1M tokens/month, up to 333k web requests, 10MB file uploads |
| Pro | $25 | n/a | No daily cap; starts at 10M tokens/month, unused tokens roll over; up to 1M web requests; up to 28% discount on annual billing |
| Teams | $30 | n/a | Per member/month; all Pro features plus shared team pool |
| Enterprise | not disclosed | n/a | Custom |
Where it wins
- Runs entirely in-browser (WebContainers) with no local setup needed to go from prompt to a running app
- Unused monthly tokens roll over on the Pro plan instead of resetting to zero
Where it falls short
- Free tier's daily/monthly token caps are consumed fast on anything beyond a trivial prototype -- one builder reported running out of credits 30 minutes in
- Users report it can move fast initially but stall or produce unworkable output once a project scales past a simple prototype
