Full-stack app generation in the browser. Prompt, edit, run, and deploy without ever spinning up a local dev environment.

Bolt.new
Added 17 May 2026
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.
Pros
- Real Node runtime in the browser means no install friction
- Generated apps are standard projects you can download and continue
- Strong support across modern JS frameworks
- One-click Netlify deploy means a live URL in minutes
Cons
- Less opinionated than Lovable, more decisions for the user
- Token-heavy generation, costs add up on iteration
- WebContainer limits make some libraries awkward
