Bolt (Bolt.new / StackBlitz)

What Bolt (Bolt.new / StackBlitz) actually is

• An in-browser development environment on StackBlitz WebContainers, so nothing installs locally
• Generates a complete codebase (front-end, back-end, a database such as Supabase) from text prompts
• Since 2026 it routes automatically to a fitting model per task, with agent choice Standard for everyone and Max on Pro only
• Token cost scales with project size: 'Most of your token usage comes from Bolt reading, understanding, and syncing your project files, so larger projects use more tokens per message' (support.bolt.new)
• A .bolt/ignore file keeps files out of the AI context, but only on the v1 Agent. v1 projects convert automatically to Bolt Agent on 3 August 2026
• Hosting and deploy straight out of the tool, with custom domains and AI image editing from the Pro tier

Limits and catches

• The loudest recurring complaint is token burn. Reviewers on Product Hunt estimate up to half their tokens go into repairing Bolt's own mistakes
• The daily cap of 300,000 tokens on Free often runs out before a first build finishes
• AI-generated authentication code looks right but regularly carries subtle bugs, and debugging those costs a lot of extra tokens. Users report hours of debugging on a basic email signup
• When Bolt gets stuck on a problem it repeats failing attempts that each cost tokens without progress
• Reviewers do not consider it reliable enough yet for non-technical founders who want to ship a production app with no developer involved

What does Bolt (Bolt.new / StackBlitz) cost?

Yes, functional but tight: $0 per month, 1 million tokens per month capped at 300,000 tokens per day, with no time limit. Bolt branding stays visible on hosted sites and file uploads are capped at 10MB. Fine for learning or an occasional try, and by several reviewer accounts not enough for a real MVP.
