# compose vs hydra

compose and hydra share 7 technologies: github.com/moby/moby/client, github.com/sirupsen/logrus, OpenTelemetry, go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/exporters/otlp/otlptrace, go.opentelemetry.io/otel/sdk, and go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. Both are written in Go.

- [docker/compose](https://seerepo.com/r/docker/compose): Define and run multi-container applications with Docker
- [ory/hydra](https://seerepo.com/r/ory/hydra): Internet-scale OpenID Certified™ OpenID Connect and OAuth2.1 provider that integrates with your user management through headless APIs. Solve OIDC/OAuth2 user cases over night. Consume as a service on Ory Network or self-host. Trusted by OpenAI and many others for scale and security. Written in Go.

- 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.
