SDK

The Rius SDK is OpenTelemetry-native tracing for AI agents: non-blocking by design, privacy-aware at export time, and speaking the OpenTelemetry GenAI conventions.

Python is available today as glassflow-ai; a JS/TS SDK is planned. Because the SDK emits standard OpenTelemetry, any language can already send traces through interoperability without waiting for a native SDK.


pip install glassflow-ai


import glassflow
 
glassflow.init(api_key="glassflow_...", service_name="my-agent")
 
@glassflow.observe
def handle(query: str) -> str:
    ...
