# kubo vs jaeger

kubo and jaeger share 8 technologies: net/http, go.opentelemetry.io/otel/trace, go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp, go.uber.org/zap, Prometheus, go.opentelemetry.io/otel/exporters/prometheus, go.opentelemetry.io/otel/sdk, and go.opentelemetry.io/otel/sdk/metric. Both are written in Go.

- [ipfs/kubo](https://seerepo.com/r/ipfs/kubo): IPFS implementation in Go: a daemon that stores and serves content-addressed data, with a CLI, HTTP Gateway, and RPC API
- [jaegertracing/jaeger](https://seerepo.com/r/jaegertracing/jaeger): CNCF Jaeger, a Distributed Tracing Platform

- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
