Bolt.new

Bolt.new by StackBlitz is what happens when you take a browser-based Node.js runtime and wire it to Claude. You describe what you want to build — a SaaS dashboard, a booking form, a portfolio site — and Bolt scaffolds the project, installs npm dependencies and spins up a live preview, all inside a browser tab. No terminal, no local environment, no Git setup required. For non-developers, it's genuinely astonishing: you can go from a text description to a deployed Netlify URL in under ten minutes. For developers, it's a fast prototyping environment that skips the boilerplate grind entirely.

The honest limitation is token budget. Simple to medium apps work well. Once you start iterating on a complex project across many files, the context window fills up and the model starts making regressions — changing something in one file while breaking something in another. Bolt is best treated as a starting point: get the scaffold right, then pull it into a proper local environment for serious development. The one-click Netlify deploy is a real differentiator — no other browser-based coding tool makes shipping to production quite this frictionless.
