Bolt.new

Overview

Bolt.new from StackBlitz uses WebContainers to run a real Node.js environment inside the browser. The agent generates a full-stack app, runs it, lets you edit live, and deploys to Netlify in one click. Same building-block idea as Lovable, different angle: closer to the metal, more flexible stack choices.

Best for

Best for
Engineers who want flexibility in stack choice and exportability

Use cases

• Building a quick proof of concept across any modern JS stack
• Generating apps you actually want to download and run locally later
• One-shot prototypes for client pitches
• Teaching full-stack development with zero setup

Notes

Why it matters

Bolt and Lovable bracket the prompt-to-app market. Lovable optimises for opinionated React + Supabase. Bolt optimises for stack flexibility and exportability.

How teams use it in production

Engineers reach for Bolt when they want a real codebase they can leave the platform with. Non-engineers usually drift to Lovable for the opinionated defaults.

What to watch

WebContainers is a genuinely novel runtime. The more the ecosystem fills in (a real database, persistent storage, edge functions) the harder it gets to leave.
