Noticed a bug?


See for guidelines.

Areas where we'd love to see contributions:

  • adding tracing to more libraries and protocols
  • interesting reports generated with Hadoop from the trace data
  • extending collector to support more transports and storage systems
  • trace data visualizations in the web UI


We use SemVer style versioning.


Thanks to everyone below for making Zipkin happen!
