Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
PyJWT lacks built-in support for more complex JWT functionalities such as JWK sets, token refreshing, and audience validation without additional libraries.
The official documentation focuses mainly on API reference but lacks comprehensive guides or tutorials for real-world use cases.
PyJWT's performance in high-throughput environments may degrade due to its pure Python implementation, which is slower compared to C-based alternatives like PyCryptodomex or Cryptography.
While open-source, the project's update frequency and responsiveness to security issues can vary, potentially leaving users vulnerable if they do not actively track releases.
