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
- Licensed under the MIT License per fastapi.tiangolo.com; as open source software it has no paid tier or vendor price to compare
- FastAPI depends entirely on Starlette for its web layer and Pydantic for validation, per its own documentation, so it is not a standalone framework and inherits both dependencies' constraints
