Bolt

Bolt is an AI-powered builder and browser-based integrated development environment created by the StackBlitz team that turns written descriptions into running full-stack web applications. Users can create websites, apps, and prototypes by chatting with AI or editing code directly inside a familiar interface. The platform scaffolds projects, installs dependencies, and runs development servers inside a WebContainer without requiring extra accounts or complex setup.

• Converts written prompts into running full-stack web apps and prototypes directly inside the browser
• Automatically routes tasks to the appropriate AI model to balance quality and cost
• Performs automatic testing, refactoring, and iterating to reduce errors
• Manages large project contexts to handle complex codebases
• Provides built-in hosting with website analytics and custom domain support
• Includes user management, authentication, and SEO optimization features
• Supports importing projects from Figma and GitHub

Pros

• Eliminates environment setup friction by running a development server directly inside the browser using WebContainers
• Speeds up prototyping and campaign page creation for non-traditional developers like marketers and product managers
• Reduces manual error-fixing cycles through automated testing, refactoring, and iteration loops
• Combines infrastructure needs like hosting, databases, and authentication into a single interface

Cons

• Free tier is restricted by a daily token limit of 300K tokens and a 10MB file upload limit
• Unused tokens on paid tiers only roll over for one additional month and require an active subscription
• Token usage scales with project size due to file system syncing, meaning larger projects consume tokens faster per message
• Teams plan subscriptions bill per team member and individual token allotments are not shared across members

Bolt fits product managers, entrepreneurs, marketers, agencies, and students looking to go from an idea to a live product, prototype, or campaign page quickly through natural language. It suits teams and builders who want to avoid stitching together separate platforms for backend infrastructure, hosting, and databases. It is a poor fit for developers who prefer manual local configuration or projects requiring complete offline control without browser-based tooling.

Bolt follows a freemium model with a free tier and three paid plans. The Free tier costs $0 and includes public and private projects, a 300K daily token limit, a 1M monthly token limit, Bolt branding, a 10MB file upload limit, website hosting, and up to 333k web requests with unlimited databases. The Pro tier costs $25 per month billed monthly, removing daily token limits, starting at 10M tokens per month, removing Bolt branding, adding private sharing, a 100MB file upload limit, up to 1M web requests, token rollover, custom domain support, SEO boosting, database provider choices, and AI image editing. The Teams tier costs $30 per month and member billed monthly, adding centralized billing, team-level access management, granular admin controls, private NPM registries, and design system knowledge. The Enterprise plan offers custom pricing with advanced security, SSO, audit logs, a dedicat

Unlike traditional local IDEs that require manual setup of servers, dependency management, and separate hosting environments, Bolt consolidates the entire lifecycle into the browser via WebContainers. It differs from standard AI code assistants by automatically routing tasks across different models and integrating cloud infrastructure such as databases, hosting, and authentication directly into the workflow. Rather than just generating code snippets, it scaffolds complete projects, runs them live, and iteratively fixes errors in a single interface.
