Plans & Pricing

Model

Standard AI model with 1M token context budget.

Usage Limits

1M tokens/month; 300K daily cap; Bolt branding on deployments; no custom domains.

Use Cases

Coding

7.5

WebContainers provide a real Node.js environment visible in the browser, giving developers more code control than pure no-code builders while requiring no local installation.

Design

7.0

Generates functional UIs but design quality is below Lovable for polished consumer-facing interfaces; stronger for functional prototypes than visual-first products.

Overview

Bolt.new is a browser-based AI application builder by StackBlitz, powered by WebContainers technology that runs a full Node.js development environment in the browser without server infrastructure. Users describe an application in natural language and receive a complete project — visible code, live preview, and editable files — without installing anything locally. Plans: Free (1M tokens/month, 300K daily cap), Pro ($25/month, 10M tokens/month, token rollover for one month), Teams ($30/user/month), and Enterprise (custom). Token consumption varies by project size — larger codebases sync more files to AI context, consuming tokens faster. Bolt reached $40M ARR in six months from launch. Primary limitation: no built-in database or authentication — these require external services like Supabase, adding setup complexity for non-technical users.

Key Features

  • WebContainers technology: runs a complete Node.js environment in the browser — no server required, no local installation, instant live preview of generated applications
  • Full code visibility: generated code is directly editable in the browser IDE, enabling developer intervention when AI output needs correction
  • Token rollover: unused Pro tokens carry over for one month, reducing waste for users with variable monthly usage patterns
  • Supabase integration: connects to Supabase for database and authentication without leaving the Bolt interface
  • Free tier: 1M tokens/month is the highest free allocation among browser-based AI app builders

Pros & Cons

Pros

  • Free tier at 1M tokens/month allows genuine prototyping before payment — the most generous free allocation among AI app builders
  • WebContainers provide a real development environment with editable code, not a locked output — developers can fix, extend, or export generated projects
  • Token rollover on Pro prevents waste for users with uneven monthly usage, unlike Lovable's daily credit reset
  • StackBlitz foundation ($105M funded) provides technical depth beyond most browser-based AI builders

Cons

  • No built-in database or authentication — Supabase integration helps but adds setup steps that create friction for non-technical users
  • Large projects consume tokens 5–10x faster because Bolt syncs the full codebase to AI context — actual capacity per project is much less than headline token count suggests
  • Free tier's 300K daily cap can block active builders before the monthly limit is reached
  • Generated code quality is not production-ready for complex applications; significant developer refinement is required beyond prototype stage

Who It's For

Best For

  • Developers who want a browser-based prototyping environment with full code access and the ability to edit AI-generated output directly
  • Founders and indie hackers who need to validate an idea with a working prototype before investing in a full engineering team
  • Hackathon participants who need fast prompt-to-deployed-app capability with no local setup overhead
  • Teams building simple internal tools or landing pages where Pro's 10M tokens and custom domains provide sufficient capacity

Not Ideal For

  • Non-technical users who need database and authentication without any setup — Lovable's built-in Supabase integration is more accessible for this use case
  • Production engineering teams who need complex backend logic, CI/CD, and deployment governance beyond Bolt's one-click model
  • Users building large codebases who will exhaust tokens faster than the headline count suggests due to full-context syncing
  • Teams who need IP indemnity for AI-generated code — no AI app builder in this category provides this protection

Audience Scores

Developers7.5

Full code visibility and edit access within the browser IDE gives developers the escape hatch to fix what AI generates incorrectly — a feature that pure no-code builders lack.

Startups8.0

Free tier with 1M tokens/month is the most generous in the AI app builder category, enabling founders to prototype and validate ideas before committing to a paid plan.

Small Business7.0

Pro at $25/month with 10M tokens and custom domains covers simple internal tools and landing pages, but no-database limitation requires external Supabase setup for data persistence.

Consider These Instead

When Not To Choose Bolt.new

Choose Lovable Pro ($25/month) if design quality and built-in Supabase database/authentication are priorities — Lovable's no-code approach is more accessible for non-technical founders. Choose Replit Core ($20/month) if you need a full IDE environment with database, deployment, and collaboration rather than a purely browser-based app builder.
