Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
PHP
- Distributed under the Modified BSD License, also called the PHP License version 4, per php.net/license/; there is no paid tier or vendor price to compare
- PHP 8.2 lost active support on 31 Dec 2024 and enters full end of life on 31 Dec 2026, with only security fixes since, per php.net/supported-versions.php (Aug 2026)
