# grpc-go vs temporal

grpc-go and temporal share 6 technologies: Google, golang.org/x/oauth2, OpenTelemetry, 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
- [temporalio/temporal](https://seerepo.com/r/temporalio/temporal): Temporal service

## What they share and what sets them apart

- In common: Google, golang.org/x/oauth2, OpenTelemetry, go.opentelemetry.io/otel/sdk/metric, Prometheus, go.opentelemetry.io/otel/sdk
- Only in grpc-go: go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/metric, go.opentelemetry.io/otel/exporters/prometheus
- Only in temporal: Gorilla, Postgres, MySQL, SQLite, AWS S3, tablewriter, github.com/aws/aws-sdk-go-v2/credentials, github.com/go-jose/go-jose/v4, go.opentelemetry.io/otel, github.com/aws/aws-sdk-go-v2, go.uber.org/zap, github.com/aws/aws-sdk-go-v2/config, go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc, github.com/felixge/httpsnoop, github.com/prometheus/client_model, go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc, go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc

## Side by side

| | grpc-go | temporal |
|---|---|---|
| Size | 335,203 lines written, 475 code files | 952,127 lines written, 1,359 code files |
| Who writes it | 0.2% of its commits signed by AI. With Gemini CLI and Claude Code | 2.9% of its commits signed by AI. With Claude Code, Cursor, and GitHub Copilot |
| Activity | Last push November 4, 2026, 5,441 commits, 23,104 stars | Last push November 4, 2026, 10,123 commits, 24,182 stars |
| Tests | 480 test files. 78.9% of its code files have a test that imports them | 1,385 test files. 85.7% 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.
