Bolt.new
About
Bolt.new is an AI app builder made by StackBlitz, a company founded in 2017 that created WebContainers, a technology that runs full development environments inside the browser. Bolt.new launched in October 2024 and grew rapidly as one of the leading prompt-to-app tools.
Users describe an app in plain language and Bolt writes the code, installs packages, runs the app and shows a live preview, all in the browser. It suits founders, developers and agencies who want to prototype or ship web apps quickly, with options to export code and deploy.
As of October 2026, Bolt has a Free plan with 1 million tokens a month and a daily cap, Pro at $25 a month starting at 10 million tokens with no daily limit and token rollover, Teams at $30 per member per month and Enterprise pricing. Costs scale with tokens, which grow as a project gets larger.
Features and integrations
-
Prompt-to-App Generation: Describe what you want and Bolt generates a working full-stack web app with a live preview.
-
In-Browser Development: Code runs inside the browser using WebContainers, so there is no local setup.
-
Plan and Discussion Modes: Talk through the approach before making code changes, which helps save tokens.
-
Built-In Hosting and Databases: Publish apps and add databases and authentication without leaving Bolt.
-
Code Export and GitHub: Download the code or connect GitHub to continue development elsewhere.
-
Custom Domains: Paid plans let users connect their own domain and remove Bolt branding.
Pros and cons
Pros
- Fast from idea to app: Working prototypes can be built and shared in minutes.
- Runs fully in the browser: No installation is required to build, run and preview apps.
- Generous free tier: The free plan includes enough tokens to test small projects.
- Code is portable: Projects can be exported or synced so developers can take over.
Cons
- Token costs grow with project size: Larger codebases use more tokens per change, so bills can rise quickly.
- Debugging can loop: The AI sometimes repeats failed fixes, wasting tokens.
- Best for web apps: Bolt is focused on web projects and is less suited to native mobile or complex backend systems.
