gogen
Please consider supporting this project by making a donation via PayPal.
gogen is a production-oriented collection of modular, reusable Go packages for building services and infrastructure code.
It solves a common problem in backend teams: repeatedly re-implementing the same foundational components (configuration loading, retries, health checks, logging, metrics, AWS integration, validation, caching, and more) across multiple repositories.
Instead of assembling and maintaining ad-hoc helpers per project, you can adopt tested packages with consistent patterns.

Why gogen
gogen is a good fit for Go teams that want:
- A consistent utility layer across services
- Reusable packages rather than project-specific scripts
- A modular import model without framework lock-in
- A practical example service to accelerate onboarding
- A Makefile-driven workflow for test/build/scaffolding
It also includes a generator path:
make project CONFIG=project.cfg
This scaffolds a new web service from the provided configuration.
Feature Highlights
-
Broad package coverage for day-to-day service needs
Why it matters: reduce dependency sprawl and avoid rewriting boilerplate utilities. -
Production-focused building blocks (HTTP, retries, observability, data stores, AWS)
Why it matters: ship services faster with less glue code. -
Consistent conventions across packages
Why it matters: easier code reviews, simpler maintenance, and predictable APIs. -
Testing-first repository culture
Why it matters: safer refactoring and more reliable behavior over time. -
Built-in project scaffolding and runnable example service
Why it matters: faster project bootstrap and clearer implementation reference.
Benefits Summary
- Faster development cycles for new services
- Less duplicated utility code across repositories
- Better consistency in operational concerns (logging, metrics, health, tracing)
- Cleaner architecture through package-level composition
- Easier onboarding for engineers joining an existing Go platform
