CI/CD Tools — GitHub Actions & GitLab CI
Four browser-based CI/CD utilities: format and structurally validate GitHub Actions workflows and GitLab CI YAML. For general YAML formatting see beautify YAML.
- Beautify GitHub Actions and GitLab CI YAML for readable reviews.
- Catch structural workflow errors before you push.
- Pair with Dockerfile and Compose checks in the same session.
Format GitHub Actions
Beautify GitHub Actions workflow YAML with 2-space indent (comments not preserved).
Validate GitHub Actions
Structural checks for on, jobs and steps — not full actionlint.
Format GitLab CI
Format .gitlab-ci.yml with 2-space indent (js-yaml round-trip).
Validate GitLab CI
Structural checks for stages, jobs and script/trigger — not a GitLab runner.

Broken YAML, missing `on` or `jobs`, empty steps: structurally validate workflows before you push — and keep actionlint in CI.
Validate Docker Compose and `.env` Files Online
