1. Acceptance of Terms

By accessing and using DevTunnel ("the Software"), you accept and agree to be bound by these Terms of Service. DevTunnel is open-source software distributed under the MIT License. If you do not agree to these terms, please do not use the Software.

2. Description of Service

DevTunnel is a self-hosted terminal forwarding tool that allows users to securely access their local terminal sessions from remote devices via Cloudflare Tunnel. The Software provides:

  • Terminal session forwarding over WebSocket connections
  • Port forwarding through Cloudflare Tunnel infrastructure
  • Passkey (WebAuthn) and passphrase-based authentication
  • Progressive Web App (PWA) capabilities for mobile access

3. Self-Hosted Nature

DevTunnel is designed to be self-hosted on your own infrastructure. You are solely responsible for the security, availability, and maintenance of your DevTunnel installation. We do not operate, host, or manage any DevTunnel instances on behalf of users.

4. Security Responsibilities

While DevTunnel includes security features such as Helmet.js headers, Content Security Policy, rate limiting, and JWT-based authentication, you are responsible for:

  • Configuring strong passphrases and JWT secrets
  • Keeping the Software and its dependencies up to date
  • Securing your Cloudflare Tunnel configuration
  • Managing access to your terminal sessions
  • Complying with applicable security best practices

No telemetry, analytics, or personal data is collected or transmitted to external services by the Software itself.
