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

Flask

  • Requires manual configuration of many common features like authentication, ORM, and admin panels
  • No built-in admin interface or scaffolding tools
  • Minimal built-in security features compared to full frameworks
