OpenCode Launches OpenTunnel: Remotely Use AI Tools on Your Computer from Your Phone

Beating AI News Flash: OpenCode co-founder Dax Raad has launched OpenTunnel, an open-source tunneling tool. It can generate public HTTPS links for websites, APIs, or OpenCode services running on a computer. For example, if you run OpenCode on your home computer, you can remotely connect from your phone when you're out and continue managing AI coding tasks, without needing to configure a public IP or router port forwarding.

This feature is similar to Tailscale Funnel, as both can expose local services to the public internet, and visitors do not need to join a private network. Both also support end-to-end encryption, with traffic decrypted only when it reaches the local machine, so relay servers cannot read the contents of normal communications.

OpenTunnel also provides an SDK, allowing developers to directly add public access functionality to their own applications. OpenCode has already completed integration and plans to launch the remote pairing feature in the official version on October 9. At that time, users will be able to connect to OpenCode running on their computer from phones and other devices via a one-time link or QR code.

However, a public link is not the same as a private connection. Anyone can try to access a public URL, and sensitive services still need to set up authentication. The community also pointed out that the operator controls the domain and certificate issuance authority, and could theoretically issue additional certificates. Dax acknowledged that users still need to trust the operator, and said users can deploy the relay service themselves.
