How do I expose localhost without opening ports? Use a reverse HTTPS tunnel. Your machine connects outbound to the tunnel service, and the public URL forwards requests back to your local app. When should I use a localhost tunnel? Use one for webhook testing, OAuth callbacks, client demos, QA previews, mobile device checks, and short-lived development reviews. Stop shipping shared passwords over Slack just to let a client view your local staging server. Push WebAuthn to your tunnel edge and lock local preview environments behind biometric passkeys. In the fast-paced landscape of modern software engineering, friction is the ultimate velocity killer. Developers routinely encounter thi...
