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.
