Supported Tracer Implementations
Zipkin supports OpenTracing in various languages via community contributions. There is an experimental bridge from Brave (Zipkin Java) instrumentation to OpenTracing and a Go implementation zipkin-go-opentracing. Some of Jaeger's client libraries (see below) can be configured to be compatible with Zipkin backend and wire format.
Appdash (background reading) is a lightweight, Golang-based distributed tracing system, originally developed and since open-sourced by sourcegraph. There is an OpenTracing-compatible
Tracer implementation that uses Appdash as a backend.

Hawkular APM supports OpenTracing-Java and has plans to support other platforms in the near future.
Instana provides an APM solution supporting OpenTracing in Java, Node.js and Go. The Instana OpenTracing tracers are interoperable with the other Instana out of the box tracers for Java, Scala, NodeJs, PHP and Ruby.
