What Bolt.new does
Bolt.new is a browser-based AI builder that generates and edits JavaScript applications, with integrated preview, databases, hosting, domains, and GitHub workflows.
Bolt.new compresses the early product-development loop into one browser surface. A user describes a website, web application, or mobile application; the agent writes the project, installs compatible packages, and shows a runnable preview. Follow-up prompts modify the same files, while direct code access lets a developer inspect or correct the result. Built-in databases, authentication, hosting, domains, and GitHub integration extend that loop beyond a disposable mockup.
The Free plan includes one million monthly tokens with a 300,000-token daily ceiling, public and private projects, hosting, unlimited databases, and Bolt branding. Pro starts at $25 monthly for ten million tokens, removes the daily cap and badge, adds custom domains and private sharing, and raises hosting and upload limits. Teams starts at $30 per member monthly with centralized controls. Token use grows with project size because synchronizing the file system consumes much of each message, so concise prompts alone do not guarantee low cost.
Bolt is effective for prototypes and conventional JavaScript products, but generated software inherits ordinary engineering risk. Database migrations, authentication rules, secrets, third-party packages, payments, accessibility, and performance all require explicit review. GitHub provides a portable history outside Bolt and should be connected before consequential work. Bolt says project data is not used to train its models. Teams should nevertheless avoid unnecessary sensitive data, check integration permissions, test production builds, and monitor hosting limits before relying on a published application.
How Bolt.new works
Bolt converts a natural-language brief into a JavaScript project inside a browser development environment, synchronizes project files into model context, and applies iterative code changes while rendering a live preview. Integrated databases, GitHub, and Bolt Cloud can then persist, version, and publish the application.
Describe one product slice
Define the user, core journey, pages, visual system, data model, and acceptance criteria in natural language. Bolt uses that brief to select a JavaScript framework and create the initial project, so narrow, testable scope produces a more maintainable foundation.
Generate code in the browser runtime
The agent creates and edits files, installs compatible packages, and renders the application in a live preview. Each interaction resynchronizes relevant project files into model context, which explains why token consumption rises as the repository grows.
Add state, identity, and version history
Bolt can provision its database and authentication, connect eligible Supabase projects, store secrets, link GitHub, and configure domains or external services. Each integration needs explicit permissions, schema review, error handling, and an independent backup or rollback plan.
Test and publish the actual system
Review source and dependencies, run the production build, test authorization and database rules, and inspect accessibility, performance, mobile layouts, and failure states. Publish through Bolt Cloud or the GitHub-based route, then monitor token, request, bandwidth, and database limits.
How to set up Bolt.new
Define a narrow first release
Write the target user, primary workflow, required pages, data entities, visual constraints, and explicit exclusions before asking Bolt to build.
Choose account and token budget
Start Free for a small prototype or select Pro or Teams after estimating project size, iteration volume, hosting traffic, and collaboration needs.
Create and inspect the scaffold
Generate the first version, open Code View, review dependencies and file structure, and fix build errors before adding more features.
Connect durable services
Link GitHub for external history, then configure Bolt Database or eligible Supabase, authentication, secrets, and domains with least-privilege access.
Harden before publishing
Test production builds, permissions, error states, accessibility, mobile behavior, security, database changes, bandwidth, and rollback before using Bolt Cloud.
Bolt.new FAQs
Is Bolt.new free?
Yes. Free currently includes one million tokens monthly, a 300,000-token daily limit, hosting, public and private projects, and Bolt-branded published sites.
How much is Bolt Pro?
Pro starts at $25 per month for ten million monthly tokens. Higher token allocations and annual billing change the price; Teams starts at $30 per member monthly.
Why does a large Bolt project use more tokens?
Bolt says much usage comes from synchronizing the project's file system into AI context, so each message can become more expensive as the codebase grows.
Can Bolt projects use GitHub?
Yes. Bolt can create or import GitHub repositories, maintain commit history, and let users continue development or deploy through services outside Bolt.
Does Bolt train models on project data?
Bolt's documentation says project data is not used to train Claude or other models. Users should still protect secrets and review every connected service's terms.
