Tech leaders have raved about AI’s potential to transform all types of work, and the clearest example so far is happening on their home turf, where a group of rapidly growing startups is offering AI tools to speed up code writing and debugging.

Lovable and Replit have also emerged as “vibe coding” leaders, helping users with varying levels of expertise make apps and websites simply by typing prompts.
