Where Replit falls short

Replit is Browser-based IDE with an AI agent that builds full apps. The trade-offs we hear from teams who switch:

  • App-flavored, not marketing-flavored — templates skew toward demos and games
  • Hosting locked to *.replit.app unless you pay up
  • UI is a code IDE — overwhelming for non-developers
