# grpc-go vs jaeger

grpc-go and jaeger share 6 technologies: go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/metric, go.opentelemetry.io/otel/exporters/prometheus, go.opentelemetry.io/otel/sdk/metric, Prometheus, and go.opentelemetry.io/otel/sdk. Both are written in Go.

- [grpc/grpc-go](https://seerepo.com/r/grpc/grpc-go): The Go language implementation of gRPC. HTTP/2 based RPC
- [jaegertracing/jaeger](https://seerepo.com/r/jaegertracing/jaeger): CNCF Jaeger, a Distributed Tracing Platform

## What they share and what sets them apart

- In common: go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/metric, go.opentelemetry.io/otel/exporters/prometheus, go.opentelemetry.io/otel/sdk/metric, Prometheus, go.opentelemetry.io/otel/sdk
- Only in grpc-go: Google, golang.org/x/oauth2, OpenTelemetry
- Only in jaeger: net/http, MCP, otelgrpc, go.uber.org/zap, go.opentelemetry.io/otel, go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp, github.com/prometheus/client_model, go.opentelemetry.io/otel/exporters/otlp/otlptrace, go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc, github.com/prometheus/common

## Side by side

| | grpc-go | jaeger |
|---|---|---|
| Size | 335,203 lines written, 475 code files | 188,919 lines written, 548 code files |
| Who writes it | 0.2% of its commits signed by AI. With Gemini CLI and Claude Code | 7.2% of its commits signed by AI. With Claude Code, GitHub Copilot, and Cursor |
| Activity | Last push November 4, 2026, 5,441 commits, 23,104 stars | Last push November 4, 2026, 4,964 commits, 23,372 stars |
| Tests | 480 test files. 78.9% of its code files have a test that imports them | 680 test files. 83.4% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- 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.
