Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bolt.new

  • The free plan is capped at 300K tokens a day and 1M tokens a month
  • Pro starts at 10M tokens a month for $25, so heavy sessions are metered rather than unlimited
  • Team seats are billed at $30 per member per month and tokens are not pooled across the team
  • Unused tokens roll over for one additional month only, so they expire after two

FastAPI

  • No built-in ORM, requires separate database libraries
  • Python-only, cannot build with other languages
  • Async/await learning curve for developers new to async programming
  • Production deployment requires separate ASGI server configuration
