Known weaknesses

   Primary language is Go, but official SDKs are only for Python and community-maintained for TypeScript

2. 02

   Performance issues under heavy load

   Docker deployment experiences latency spikes with more than 10 concurrent requests

3. 03

   Small community leading to limited support and contributions

   GitHub issues have slow response times, few contributors
