Bolt.new
Generate, run, and deploy full-stack web apps directly in the browser using WebContainers, no local setup required. Token-metered pricing with unused tokens rolling over one month.
The verdict on Bolt.new: Developers who want to describe an app and get a working full-stack build in the browser Bolt.new is aimed at developers who want to skip local setup entirely and go from a description to a running full-stack app inside the browser. Pricing: Free (1M tokens) / $25/mo Pro (10M tokens) / $30/member Teams. Last reviewed: August 2026.
Best For
Developers who want to describe an app and get a working full-stack build in the browser
Standout Feature
A full in-browser Node.js runtime and terminal, so the AI can install packages and run the app, not just write code
TL;DR
Excellent for prototyping fast, token limits mean complex builds need real prompt iteration to get across the finish line.
Alternatives
Overview
Bolt.new is a browser-based AI development environment by StackBlitz where you describe what you want to build and receive a working, runnable full-stack application, all in the browser, with no local setup required. It combines an AI model (Claude or GPT-4) with a full in-browser Node.js runtime, file system, and terminal, so the AI can write code, install packages, run the app, observe errors, and fix them in a self-contained loop. The result is a genuinely interactive development environment where the AI iterates until the app works, not just a code generator that outputs a static file. Applications built in Bolt.new can be deployed directly to Netlify with one click.
Typical use cases: rapid MVP prototyping, building small internal tools, creating demo applications for pitches, and learning new frameworks by watching the AI build example applications. The free tier provides limited monthly usage. Paid plans start at $20/month for more AI interactions and higher compute. Bolt.new competes directly with Lovable and Replit Agent for the 'full-stack app from a description' use case.
Our Take
The in-browser Node.js runtime is what makes this real: the agent installs packages and runs the app, not just writes files you configure yourself. The practical ceiling is the token meter. Complex builds can stall mid-way, which means careful prompt iteration becomes part of the work. Strong choice for prototyping something quickly; plan for iteration budget if the spec is large.
