Bolt.new is an AI-powered web application builder that generates, edits, and deploys full-stack applications directly in the browser using simple text prompts and StackBlitz's WebContainer runtime, eliminating the need for local development environments.
AI-powered web application builder that generates full-stack apps from text descriptions with instant browser deployment.
Bolt.new is a browser-based AI development platform created by StackBlitz that allows users to generate, edit, run, and deploy complete full-stack web applications using natural language prompts. Built on StackBlitz's WebContainer technology—a WebAssembly-based Node.js runtime that executes entirely in the browser—Bolt.new eliminates the traditional friction of local development setup, dependency management, and environment configuration.
The platform operates through an agentic AI workflow: users describe what they want to build in plain English, and Bolt's AI agent autonomously scaffolds the project, creates and edits files across the codebase, installs npm packages, runs build commands, interprets error output, and self-corrects through iterative reasoning loops. This approach mirrors how a junior developer would work through a task, but at significantly faster speed.
Bolt.new supports modern JavaScript and TypeScript frameworks including React, Next.js, Astro, Remix, Vite, and Svelte, generating idiomatic code rather than proprietary syntax. First-party integrations with Supabase (authentication, Postgres database), Stripe (payments), and Expo (cross-platform mobile) enable users to build genuinely functional product prototypes—not just static mockups.
Deployment is streamlined through one-click publishing to Netlify, with automatic build configuration and optional custom domain support on paid plans. Projects can also be exported to GitHub at any time, preserving full code ownership and enabling continued development in local IDEs like VS Code or Cursor.
The platform uses a token-based pricing model starting with a free tier that provides a daily token allowance for experimentation. The Pro plan at $20/month includes 10 million monthly tokens with unused token rollover, private projects, and priority AI model access. Higher tiers (Pro 50, Pro 100, Pro 200) scale token allowances for power users, while Teams and Enterprise plans add collaborative workspaces, SSO, centralized billing, and dedicated support.
As of early 2026, Bolt.new has served over 10 million users and processes approximately 2 million prompts per day, making it one of the most widely adopted AI-powered development platforms. The platform has seen particular traction among non-technical founders building MVPs, freelancers delivering client websites, and enterprise teams rapidly prototyping internal tools.

Bolt.new transforms web development through AI-powered full-stack generation directly in the browser. At $20/month Pro pricing, it provides 10M monthly tokens with rollover for private projects and custom domains. The platform excels at rapid prototyping and MVP development, where its agentic AI workflow can produce functional applications in minutes. With over 10 million users as of 2026 and first-party integrations for Supabase, Stripe, and Netlify deployment, Bolt.new delivers genuine end-to-end capability. However, it remains limited to the JavaScript/TypeScript ecosystem and struggles with large codebases exceeding 50 files. Best suited for startups, freelancers, and non-technical founders who need to ship fast rather than teams maintaining complex production systems.
StackBlitz's proprietary in-browser Node.js runtime executes the entire dev environment client-side, eliminating the need for cloud VMs or local installs while delivering near-native performance. The WebAssembly-based runtime supports npm package installation, build tooling, and dev server execution entirely within the browser tab.
The AI agent autonomously creates and edits multiple files, installs npm packages, runs build commands, reads error logs, and self-corrects through a multi-step reasoning loop. This agentic workflow handles complete feature implementation from a single natural language prompt, iterating until the build succeeds and the output matches the user's intent.
Every change instantly reflects in a live in-browser preview, and users can click on UI elements or describe bugs in natural language to direct the agent's next edit.
Generated apps can be deployed to a public production URL on Netlify with a single click, with build configuration handled automatically.
First-party integrations for authentication, Postgres, payments, and cross-platform mobile (via Expo) enable genuinely functional product prototypes with real backend services and payment processing out of the box.
Projects can be pushed to a user-owned GitHub repository at any time, preserving full code ownership and enabling continued development in any local IDE.
Built-in diff visualization and version rollback let users review every AI-generated change and revert if a regression is introduced.

Weekly insights on the latest AI tools, features, and trends delivered to your inbox.
In 2026 Bolt.new has expanded its agentic capabilities with deeper multi-file reasoning, an improved error-recovery loop that reduces token waste during debugging, and the introduction of Expo integration for cross-platform mobile app generation. The platform surpassed 10 million registered users in early 2026 and now processes approximately 2 million prompts per day. Additional updates include diff-view and rollback functionality for reviewing AI-generated changes, enhanced Supabase integration with direct database schema editing, and new team collaboration features with shared workspaces and pooled token allowances on the Teams plan.
