GitHub Actions Generator
Build a complete, valid GitHub Actions workflow visually — triggers with branch/path filters, multiple jobs with a build matrix and job dependencies, and steps assembled from a catalog of the real actions (checkout, setup-node, cache, deploy-pages, docker build-push…). The YAML renders live as you edit, and a linter catches the mistakes people actually ship: missing checkout, a deploy job without pages permissions, a hard-coded secret, or a needs reference to a job that doesn't exist.
About this ToolHow it works, benefits & use casesTap to collapse
Most GitHub Actions generators hand you one fixed template and leave the editing to you. This one is a real workflow builder: it models the workflow as triggers, jobs, a build matrix, and ordered steps, then emits valid YAML live as you edit. Choose your events (push, pull_request, workflow_dispatch, schedule, release) with branch and path filters, set repository permissions and a concurrency group, and declare workflow-level env vars. Add as many jobs as you need, give each a runner, an optional Node build matrix, and needs dependencies on other jobs, then assemble steps from a catalogue of the real actions — actions/checkout, setup-node, cache, upload-artifact, deploy-pages, docker build-push — or drop in custom run commands and custom uses steps, reordering them inline. A built-in linter flags the mistakes people actually ship, and the whole workflow is captured in a shareable URL so you can hand a teammate the exact pipeline.
How to Use
- 1Start from a preset (Node CI, Deploy to Pages, Publish to npm, Docker, Python CI) or build from scratch.
- 2Pick your triggers and add branch/path filters or a cron schedule; set permissions and concurrency.
- 3Add jobs — give each a runner, optionally enable a Node matrix, and set needs dependencies.
- 4Assemble each job’s steps from the catalogue (checkout, setup-node, cache, build, deploy…) or add custom run/uses steps, then reorder them.
- 5Watch the YAML render live, read the linter for problems, then copy or download workflow.yml into .github/workflows/.
Key Benefits
- A true builder — multiple jobs, a build matrix, and needs dependencies, not a single template
- Steps assembled from a catalogue of the real, current actions (checkout v4, setup-node v4, deploy-pages v4…)
- Live, valid YAML that re-renders instantly as you edit — including correct matrix and expression syntax
- A linter that catches missing checkout, deploy without pages permissions, hard-coded secrets, and bad needs references
- Triggers with branch/path filters and cron, configurable permissions, concurrency, and env
- Five presets covering CI, GitHub Pages, npm publish, Docker, and Python
- Shareable URL captures the entire workflow for handoff
Common Use Cases
- Standing up a Node CI pipeline that lints, tests, and builds across a version matrix
- Wiring a build → deploy job chain for GitHub Pages with the correct permissions
- Generating a Docker build-and-push workflow or an npm publish-on-release workflow
- Teaching the structure of a workflow — jobs, matrix, needs — by seeing the YAML update as you change the model
- Auditing a draft workflow for missing checkout, leaked secrets, or permission gaps before committing it

Workflow
Adds a concurrency group keyed on workflow + ref.
Triggers
Environment variables
No workflow-level env vars.
Jobs
runs-on becomes ${{ matrix.os }} across these versions.
A builder, not a template picker
Most generators hand you one fixed template. This one models the workflow — jobs, a build matrix, needs dependencies, and steps from a catalog of the actual actions — and emits the YAML live, so you can compose exactly the pipeline you want and still get valid output.
What the linter catches
- Build/test steps with no
actions/checkout— your code never lands on the runner. - A Deploy-Pages step without
pages: write/id-token: write. - A secret hard-coded in a
run:line instead of${{ secrets.* }}. - A
needs:pointing at a job that isn’t defined.

A gallery gives you a frozen file you then have to hand-edit. This tool keeps a live model of the workflow — you add and remove jobs, toggle a matrix, set job dependencies, and reorder steps — and regenerates the YAML on every change. You get the flexibility of writing it by hand with the safety of always-valid output and a linter watching your back.
Yes. The emitter produces standard GitHub Actions YAML with correct indentation, quoting (cron is quoted, matrix expressions like ${{ matrix.node-version }} are left as plain scalars), and block scalars for multi-line run commands. The step catalogue uses current action versions (actions/checkout@v4, actions/setup-node@v4, actions/deploy-pages@v4, docker/build-push-action@v6).
