GitHub Actions Workflow Builder

The GitHub Actions Workflow Builder is a free browser-based tool that helps you create GitHub Actions workflow YAML files through a visual form instead of writing YAML from scratch. Select triggers (push, pull_request, schedule, workflow_dispatch), define jobs with runner environments, and add steps using common actions or custom run commands. The tool generates valid workflow YAML that you can copy directly into your .github/workflows/ directory.

The builder supports all major workflow features: multiple trigger types with branch and path filtering, matrix strategy configuration for testing across multiple versions or operating systems, environment variables at the workflow, job, and step levels, conditional execution with if expressions, job dependencies via needs, and secret references using the ${{ secrets.NAME }} syntax. A library of common actions is built in, including actions/checkout, actions/setup-node, actions/setup-python, actions/cache, docker/build-push-action, and more, each pre-populated with sensible defaults.

If you need to format or validate your YAML, try the YAML Formatter for indentation and syntax checking. For building Docker run commands, the Docker Run Command Builder provides a similar visual experience. And if you work with Kubernetes manifests, the K8s Pod Spec Builder can help build deployment YAML visually.

All processing runs entirely in your browser. No workflow configurations, secrets references, or repository information is ever sent to any server. This tool is safe to use with real project configurations and production workflow settings.

1. Enter a Workflow Name at the top of the form (e.g., "CI", "Deploy", "Release").
2. Configure Triggers by selecting event types (push, pull_request, schedule, etc.) and optionally filtering by branches or paths.
3. Add Global Environment Variables if your workflow needs shared env vars across all jobs.
4. Define a Job by setting the job ID, display name, and runner environment (ubuntu-latest, macos-latest, etc.).
5. Add Steps to each job: choose "Use Action" to select from common actions with pre-filled inputs, or "Run Command" to write shell commands directly.
6. Optionally enable Matrix Strategy to test across multiple versions (e.g., Node.js 18, 20, 22) or operating systems.
7. Review the Generated YAML in the right panel, then click Copy or press Ctrl+Shift+C to copy it, or click Download to save as a .yml file.
