Where each one falls short

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

Bazel

  • Steep learning curve for developers unfamiliar with build systems
  • Initial setup complexity; requires BUILD files and Bazel configuration
  • Verbose error messages can be difficult to debug for new users
  • Smaller community and fewer third-party integrations vs enterprise tools

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
