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

HTMX

  • Best suited for server-rendered architectures, not pure client-side SPAs
  • Limited client-side state management capabilities compared to frameworks
  • Smaller ecosystem with fewer third-party libraries and tools
  • Learning curve for developers from JavaScript framework backgrounds
