Tachyon Guides

Practical guides for using Tachyon in development and CI/CD.

Webhook Testing

Test webhooks from Stripe, GitHub, and other services locally.

tcn share 3000
# → https://abc123.tunnel.dotsetlabs.com

Copy the tunnel URL to your provider: https://abc123.tunnel.dotsetlabs.com/api/webhooks/stripe

Tachyon captures incoming requests. Open the Inspector to see payloads.

Share your local environment with teammates.

tcn share 3000 --subdomain my-feature

By default, only your team members can access this URL.

tcn share 3000 --public

Create preview environments for pull requests.

Use the TACHYON_AUTH_TOKEN environment variable in your CI provider.

- name: Start app & create tunnel
  run: |
    npm start &
    sleep 5
    tcn share 3000 --subdomain pr-${{ github.event.pull_request.number }}

Use a script to post the URL https://pr-${{ github.event.pull_request.number }}.tunnel.dotsetlabs.com back to the PR as a comment.
