# grpc-go vs go-micro

grpc-go and go-micro share 3 technologies: OpenTelemetry, 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
- [micro/go-micro](https://seerepo.com/r/micro/go-micro): A framework for agents, tools and services

## What they share and what sets them apart

- In common: OpenTelemetry, Prometheus, go.opentelemetry.io/otel/sdk
- Only in grpc-go: Google, golang.org/x/oauth2, go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/metric, go.opentelemetry.io/otel/exporters/prometheus, go.opentelemetry.io/otel/sdk/metric
- Only in go-micro: net/http, go-redis, go-sqlite3, pgx, pq, NATS.io, github.com/nats-io/nats-server/v2, Postgres, RabbitMQ, Redis, github.com/patrickmn/go-cache, etcd, MySQL, SQLite, charm.land/glamour/v2, github.com/golang-jwt/jwt/v5, LangChain, Pydantic, go.opentelemetry.io/otel, go.uber.org/zap, github.com/prometheus/client_model

## Side by side

| | grpc-go | go-micro |
|---|---|---|
| Size | 335,203 lines written, 475 code files | 138,184 lines written, 500 code files |
| Who writes it | 0.2% of its commits signed by AI. With Gemini CLI and Claude Code | 20.5% of its commits signed by AI. With Codex, Claude Code, and GitHub Copilot |
| Activity | Last push November 4, 2026, 5,441 commits, 23,104 stars | Last push October 29, 2026, 4,427 commits, 23,083 stars |
| Tests | 480 test files. 78.9% of its code files have a test that imports them | 286 test files. 62.8% 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.
