wrkflw
WRKFLW is a command-line tool that lets you validate and run GitHub Actions workflows on your local machine before pushing to GitHub. It supports multiple execution modes (Docker, Podman, or no containers) and includes a terminal UI for interactive workflow management.

What wrkflw is
A Rust-based CLI that parses and executes GitHub Actions YAML, supporting job dependencies, matrix builds, composite actions, reusable workflows, expression evaluation, and multiple runtime backends. Includes workflow validation with CI/CD-friendly exit codes and trigger-aware filtering based on file diffs.

Best use cases
Implementation considerations
- Requires Docker, Podman, or host OS to run workflows; emulation and secure-emulation modes exist but may not cover all shell/language scenarios.
- Job dependencies are resolved correctly, but `concurrency:` groups are parsed but not enforced.
- Expression evaluator supports common functions but functionality gaps may exist for edge cases.
- Private repos in `uses:` statements require authentication workarounds outside the tool.
- Watch mode requires git to detect changed files; you can also supply `--changed-files` explicitly.
When to avoid it — and what to weigh
- You require Windows or macOS runner simulation — Tool silently maps Windows/macOS runners to container images; `${{ runner.os }}` reflects host OS, not the declared `runs-on`.
- You need service container support — `services:` blocks are parsed but never started, so workflows depending on MySQL, Redis, or other services will fail.
- You use private repos for remote reusable workflows — Remote `uses:` are cloned unauthenticated over HTTPS, so private repositories cannot be accessed.
- You need GitHub encrypted secrets or fine-grained permissions — These are not yet supported; only basic secret management via env, file, or external vaults (AWS, Azure, GCP, Vault) is available.
License & commercial use

Secure-emulation mode sandboxes host processes with filesystem/network restrictions, avoiding full container overhead for untrusted workflows. Supports AES-256-GCM encryption for stored secrets. Masking of secrets in logs is mentioned. No details on vulnerability disclosure policy or security audit history; usual open-source practices apply. Users should review code before executing arbitrary workflows.
Alternatives to consider
act (nektos/act)
Docker-first local GitHub Actions runner; more mature and widely adopted. Lacks TUI, watch mode, and some advanced features like secure-emulation.
github-runner (official GitHub Actions Runner)
Official runner for self-hosted deployments. Not designed for local dev; focuses on on-premise CI infrastructure rather than laptop testing.
WorkflowCI (GitHub UI)
Native GitHub UI for workflow authoring and debugging. Requires pushing commits; no local-first iteration or watch mode.
