Ran through the Bolt.new tutorial workflow properly, here is what the integrated environment actually feels like

The live preview running alongside the generation is the part that changes how iteration feels. You are not generating and then switching to check what was produced. The preview updates as the generation happens which means you can redirect mid-generation if the direction is wrong rather than waiting for a complete output to evaluate.

GitHub integration being built into the workflow rather than being an afterthought is the professional detail that matters for anything intended to be maintained and extended. Getting generated code into version control from the first commit rather than treating it as something to set up later changes the project's future maintainability.

The Supabase backend connectivity making persistent state achievable directly from the builder is what separates a working prototype from a deployed application with real data. The ROAS calculator example in the tutorial shows this concretely with live calculations against inputs that persist across sessions.

Instant deployment to Netlify meaning the path from first generation to public URL is a single step is the demonstration speed capability that changes what is achievable in a single working session with a client.

What is the most complex thing you have built in Bolt without hitting a wall that required manual code to resolve?
