For rapid prototyping, I use Lovable, which acts as a "GPT-engineer," building full-stack web apps (integrated with Supabase and GitHub) from simple natural language prompts. When I need a fully autonomous software engineer, I turn to Devin, which can plan and execute end-to-end engineering tasks, fix bugs, and even learn new technologies on the fly. Finally, Warp serves as my command center; its Agent Mode turns the terminal into an intelligent partner, letting me debug errors and run complex workflows using natural language directly in the command line.
