Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Cloudflare Workers support is limited and requires specific configuration and manual workarounds for tracing and WebSockets.

   The SDK requires nodejs_compat to be enabled, traces must be manually flushed, and outbound WebSocket connections must use a fetch-based upgrade rather than the global constructor.

2. 02

   Tracing is disabled by default in browser environments and may be inaccurate in v8 isolates.

   The core SDK disables tracing by default when bundled for browser use, and tracing does not work in v8 isolates which have not been extensively tested.

3. 03

   Realtime SDK is incompatible with Azure OpenAI Realtime due to unsupported fields and ignored initial configuration.

   The SDK emits OpenAI-specific fields that Azure rejects, and initial agent configuration is ignored during WebRTC session creation until the data channel opens, preventing clean configuration application.

4. 04

   React Native support requires developers to provide their own native WebRTC transport and manage permissions and audio routing.

   The built-in WebRTC implementation is browser-only, forcing React Native apps to use external libraries like react-native-webrtc and handle transport lifecycle and permissions themselves.
