Bolt.new is an AI-powered development environment that allows you to prompt, build, and deploy full-stack web applications entirely within your browser.

What can I build with Bolt.new?

It is optimized for the JavaScript ecosystem, including React, Next.js, Vite, and mobile prototypes via Expo.

Bolt.new typically offers a tiered model where free users have limited token usage, while paid tiers allow for larger projects and more complex reasoning.

What are the primary limitations?

The main constraints are the lack of support for non-JS runtimes like Python or Go and the memory limits of the browser-based WebContainer.

Technical Analysis

Bolt.new leverages StackBlitz WebContainer technology to run Node.js directly in the browser's micro-VM. This enables a seamless 'agentic' workflow where the AI can create files, install dependencies, and run terminal commands without requiring a local environment. Its context-awareness is high because it manages the entire project lifecycle—from scaffolding to debugging—within a single unified state.

While the agentic mode is highly effective for 'vibe-coding' or rapid prototyping, it is inherently bound by browser resources. As projects grow in complexity, the token consumption increases significantly, and the browser sandbox may encounter memory or CPU throttling. Furthermore, because it relies on Node.js runtimes, developers cannot natively execute languages like Rust, Python, or Go within the internal environment.

Limitations & Considerations
