I talked to Kasper Junge from Computerlove.Tech recently, and he made a point that has stuck with me.
If you’re a product manager building prototypes with AI, you should consider Claude Cowork instead of Lovable.
⚡ The argument in short
Lovable is cloud-based and locked to one specific stack. That works fine, until you hand the prototype over to IT, and the developers look at React, Supabase and the rest of the setup and ask: “What the hell is this?” It’s a long way from plug-and-play with your existing codebase.
Cowork (and Claude Code) runs locally and is stack-agnostic. That means you can go to a developer colleague and ask for an instruction file that tells the agent how you build software at your company. Suddenly your prototype looks like something that can actually live on in production: same programming language, same architecture, same conventions.
👉 Bonus: Cowork isn’t just for web apps. You can build desktop apps, Chrome extensions and small automation scripts in the same tool.
🎯 What does it mean for you?
If you build prototypes to get your hands on a problem and jam ideas with users: go with Lovable, it’s fast. But if the prototype needs to be reusable by the development team, start in Cowork with an instruction file made together with a developer. It saves you a conversion later.
