Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API requires Python-specific patterns, TypeScript SDK is community-maintained
v0.1 to v0.2 migration required rewriting chain definitions
Niche framework with a smaller ecosystem compared to more mainstream Python frameworks like Django or Flask
Concurrency benefits are limited by the Global Interpreter Lock (GIL) in CPython, which can bottleneck multi-threaded performance
