Windsurf
Windsurf is the world's first agentic IDE featuring Cascade, an AI agent that combines deep codebase understanding with real-time awareness of your actions to enable autonomous, collaborative coding workflows.

Bolt.new integrates cutting-edge AI models with an in-browser development environment powered by StackBlitz's revolutionary WebContainers technology. WebContainers is a micro-operating system designed to run Node.js applications directly inside the browser, providing a complete and isolated development environment without virtual machines or cloud servers. This architecture results in faster load times, reduced resource usage, and enhanced security compared to traditional cloud-hosted AI agents. The platform gives AI models unprecedented control over the entire development environment, including the filesystem, Node server, package manager, terminal, and browser console. This means AI can handle the complete application lifecycle – from initial scaffolding through debugging to final deployment. Bolt.new allows you to describe what you want in natural language, and the AI builds it for you using modern frontend tools and frameworks. Built by the creators of StackBlitz, Bolt.new has achieved remarkable growth, reaching $4M ARR in just 4 weeks and growing to 2 million registered users. The platform supports most popular JavaScript frameworks and libraries, and every project includes a free bolt.host subdomain with one-click deployment options to Netlify, Vercel, and Cloudflare. The open-source codebase is available on GitHub for developers interested in building their own AI-powered development tools. Bolt.new is particularly powerful for rapid prototyping, MVP development, and creating functional web applications without extensive coding knowledge. It excels at frontend development and full-stack JavaScript applications, making it ideal for founders, designers, and developers who need to move fast.
