My Recommendations

Designers who want their Figma designs to become real apps: Bolt.new - the workflow is smooth

Non-coders who want granular control: Lovable.dev - being able to select and modify specific parts is brilliant

Complete beginners who want to build business apps: Davia - those business integrations are game-changing

Developers who want proper documentation: Tempo Labs - those auto-generated PRDs are actually useful

Anyone tired of AI development frustrations: Combini - they really thought about the pain points

Minimalists: Base44 - bare bones but flexible

The vibe coding space is moving incredibly fast. What I love most is that each tool is solving different problems rather than just copying each other. Whether you're a complete beginner or a seasoned developer, there's probably something here that'll change how you think about building software.

The real question isn't which tool is "best" - it's which one matches your vibe.
