reflex-otel Changelog

v0.2.0 (2026-10-08)

Breaking Changes

  • Require Python 3.11 or newer; Python 3.10 is no longer supported.
  • Require reflex-base 0.10 or newer.

v0.1.0 (2026-09-11)

Features

  • Add the reflex-otel package: an OpenTelemetry instrumentor that turns on the framework's built-in trace points and metrics (one span per event handler run, chained events parented under the enqueuing span, frontend traceparent propagation, event/state/websocket metrics, compile spans) and wraps the ASGI app in the OpenTelemetry ASGI middleware. OtelPlugin(endpoint=...) adds browser tracing (a traceparent on sampled events and uploads, web vitals, React render timing) to the compiled frontend; without an endpoint nothing is exported. Failed browser exports (for example a collector without CORS) are reported through the app's frontend_exception_handler. (#6227)

Documentation

  • Correct the environment-variable setup example to select HTTP/protobuf for the installed OTLP HTTP exporter. (#7086)
