Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Daphne is tightly integrated with ASGI and primarily supports Python, making it less accessible for developers working in other languages.
Configuring Daphne to work with non-ASGI frameworks requires significant manual configuration and understanding of ASGI internals.
The official documentation is sparse on advanced topics such as custom middleware, performance tuning, and debugging techniques.
Daphne's performance can degrade under heavy load or when handling a large number of concurrent connections without proper tuning.
