Show HN: Wush Action – SSH into GitHub Actions

SSH into GitHub Actions using wush. Debug workflows as if they were running on your machine.

1. Add coder/wush-action to a GitHub Actions workflow:

2. Install wush on your local machine:

3. Copy the authentication key from GitHub Actions logs:

4. Run wush ssh, and paste the key.

5. You're in!

• Linux (x86_64 and arm64)
• Windows (x86_64 and arm64)
• macOS (x86_64 and arm64)

Wush establishes a WireGuard tunnel between your local machine and a GitHub Actions runner - traffic is E2E-encrypted. It doesn't require you to trust any 3rd party authentication or relay servers, instead using x25519 keys to authenticate connections.

For more information, see wush's README and source code.

To run coder/wush-action regardless of whether a job succeeds or fails, consider using ${{ !cancelled() }} instead of ${{ always() }}:

always() is immune to cancellation, so you won't be able to stop wush by cancelling the workflow. Instead, you'll need to SSH into GitHub Actions and kill the wush process manually.
