Bolt
Create stunning apps & websites by chatting with AI.
Bolt.new is a browser-based AI development agent that allows users to prompt, run, and deploy full-stack web applications. It utilizes advanced coding agents to handle complex project contexts, automated refactoring, and error reduction. The platform integrates essential backend infrastructure, including databases, hosting, and authentication, enabling builders to move from a chat interface to a live production environment without manual configuration.

Bolt at a glance
Overall Score
Bolt.new is StackBlitz's browser-based AI app builder, and it runs on WebContainers technology that spins up a full Node.js environment right inside Chromium. That means you can build, preview, install npm packages, wire up a database like Supabase, and deploy to Netlify without ever touching a local dev setup.
Where it shines: taking a plain-text prompt to a working full-stack MVP in minutes. Where it struggles is anything past that early stage: once a project grows past roughly a thousand lines of code, reliability drops off fast, and the AI starts burning through tokens rewriting whole files instead of making small, precise edits.
Pros
- Zero local setup, terminal commands and a live Node.js server run right in the browser
- Generates a genuinely full stack in one pass: front end, backend logic, routing, and database schema across frameworks like React, Next.js, and Supabase
- Built-in error detection reads the terminal output and attempts automatic fixes when something breaks
- One-click deployment straight to live hosting on Netlify
- First-time experience is genuinely smooth, closer to chatting with an AI than wrestling with an IDE
Cons
- Token consumption is opaque and aggressive, the AI often rewrites entire files for small fixes instead of precise diffs
- Reliability drops sharply on larger codebases, with context loss, hallucination loops, and previously fixed bugs reappearing
- The free daily token quota is thin enough that it can be used up in one or two multi-file prompts
- No formal GDPR, SOC 2, or HIPAA compliance, so it's not a fit for anything handling sensitive data
- Customer support is one of the most heavily criticized parts of the platform, with slow or unresolved billing and token disputes
Bolt.new is genuinely impressive at what it's built for: getting a working 0-to-1 prototype live in minutes without setting up a single thing locally. If you're validating an idea or building a quick demo, the speed here is hard to match, and having a real Node.js environment in the browser instead of a sandboxed toy makes a real difference.
