# caddy vs grpc-go

caddy and grpc-go share 4 technologies: Prometheus, OpenTelemetry, go.opentelemetry.io/otel/trace, and go.opentelemetry.io/otel/sdk/metric. Both are written in Go.

- [caddyserver/caddy](https://seerepo.com/r/caddyserver/caddy): Fast and extensible multi-platform HTTP/1-2-3 web server with automatic HTTPS
- [grpc/grpc-go](https://seerepo.com/r/grpc/grpc-go): The Go language implementation of gRPC. HTTP/2 based RPC

## What they share and what sets them apart

- In common: Prometheus, OpenTelemetry, go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/metric
- Only in caddy: chi, etcd, github.com/yuin/goldmark, go.uber.org/zap, go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp, go.opentelemetry.io/otel, github.com/prometheus/client_model, go.opentelemetry.io/contrib/bridges/prometheus
- Only in grpc-go: Google, golang.org/x/oauth2, go.opentelemetry.io/otel/metric, go.opentelemetry.io/otel/exporters/prometheus, go.opentelemetry.io/otel/sdk

| Who writes it | 0.9% of its commits signed by AI. With Claude Code, GitHub Copilot, Gemini CLI, and Amp | 0.2% of its commits signed by AI. With Gemini CLI and Claude Code |
| Activity | Last push November 4, 2026, 2,817 commits, 78,770 stars | Last push November 4, 2026, 5,441 commits, 23,104 stars |
| Tests | 193 test files. 65.6% of its code files have a test that imports them | 480 test files. 78.9% 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.
