Supabase added W3C Trace Context propagation to supabase-js, allowing client trace IDs to flow into API Gateway and Edge Function logs.
When enabled, the SDK attaches traceparent, tracestate, and baggage headers to Supabase requests, enabling end-to-end request tracing from browser to backend logs.
The feature is also available in Swift, Flutter, and Python SDKs.
