Bolt.new vs Windsurf
Bolt.new validates ideas fast. Windsurf builds production-quality code. They serve different product stages — prototype in Bolt, build properly in Windsurf.
Bolt.new and Windsurf sit at opposite ends of the AI coding spectrum. Bolt is a no-code builder — describe your app and get a working prototype in minutes without writing a single line. Windsurf is an AI-powered IDE for developers — you write code with AI assistance, maintaining full control over every decision. Comparing them reveals what you gain and lose at each end of the vibe coding spectrum.
Head-to-head comparison
Code Quality
WindsurfBolt.new
Functional but rough. Large files, loose TypeScript, minimal separation of concerns. The code works as a prototype but structure degrades as the app grows.
Windsurf
Well-structured multi-file projects with clean separation of concerns. Good TypeScript usage. Modular architecture that's maintainable long-term.
Security
WindsurfBolt.new
No security layer — no auth, no validation, sometimes hardcoded API keys. The prototype has zero protection by design.
Windsurf
Has security infrastructure but with subtle gaps — auth middleware with logical bypasses, queries that occasionally use string concatenation, error messages that leak internals.
Ease of Use
Bolt.newBolt.new
No coding required. Describe your app in plain English and get a working prototype in minutes. The lowest barrier to entry of any AI tool.
Windsurf
Requires development experience. It's a full IDE with AI assistance — powerful but aimed at professional developers.
Deployment
WindsurfBolt.new
Export from WebContainer and deploy to standard hosts. May need env var cleanup and configuration, but fundamentally portable.
Windsurf
Standard project output that deploys to any platform. Proper build configuration, environment variable handling, and deployment-ready architecture.
Scalability
WindsurfBolt.new
Prototypes aren't built to scale. No data layer, no caching, no backend optimization. Going to production means rebuilding, not just deploying.
Windsurf
Production-viable architecture from the start. May have N+1 query issues and missing indexes, but the foundation supports scaling with targeted fixes.
Speed of Prototyping
Bolt.newBolt.new
Fastest path from idea to working demo. Minutes, not hours. Instant preview in the browser. Unmatched for rapid validation.
Windsurf
Faster than manual coding but still hours to days for a complete app. You're building properly, which takes longer.
Code quality
Windsurf produces significantly better code — more structured, more maintainable, and closer to production-ready. Bolt wins on speed and accessibility. The gap between a Bolt prototype and production code is large: you'll need to add a backend, implement security, refactor the structure, and add error handling. A Windsurf project needs targeted fixes (auth gaps, query optimization) but the foundation is solid.
Security
Bolt has no security — it's a prototyping tool and doesn't pretend otherwise. Windsurf has security infrastructure with subtle gaps — auth that looks correct but has bypass routes, queries that are mostly parameterized but sometimes aren't. Windsurf's issues are more insidious because they pass casual inspection. Both need a security review, but the scope of work is very different.
Which should you choose?
Choose Bolt.new if...
Non-technical founders who need a working demo fast. Best for idea validation, investor demos, and figuring out what to build before investing in real development.
Bolt.new servicesChoose Windsurf if...
Developers building production applications. Best when code quality, maintainability, and security matter from the start.
Windsurf servicesThe bottom line
Use Bolt to validate your idea in an afternoon. Use Windsurf to build the real thing. They serve different stages of the product lifecycle, not different approaches to the same problem. If you vibe coded a prototype in Bolt and it's gaining traction, the next step is a proper build — and a code review to map exactly what needs to change. SpringCode reviews vibe coded apps from both tools and tells you exactly what stands between your prototype and production.

Frequently asked questions
Can I take my Bolt prototype and continue building in Windsurf?
You can export your Bolt project and open it in Windsurf, but you'll likely want to restructure significantly. Think of the Bolt output as a working spec — it shows what the app should do. Windsurf is where you build it properly with clean architecture and security.
I'm a developer — should I ever use Bolt?
Yes — for rapid prototyping and client demos. Bolt is the fastest way to show a stakeholder what an app could look like. Once the concept is validated, switch to Windsurf (or Cursor) for the production build. Don't try to turn a Bolt prototype into production code.
