OpenCode launches OpenTunnel: Mobile devices can now remotely use AI tools stored on personal computers.

Beating AI Express News: OpenCode co-founder Dax Raad has launched OpenTunnel, an open-source internal network penetration tool that generates public HTTPS links for websites, APIs, or OpenCode services running on a local computer. For example, users can run OpenCode on their home PC and remotely connect via a mobile device when away to continue managing AI programming tasks, without needing to configure a public IP or router port forwarding. This functionality is similar to Tailscale Funnel, both enabling local services to be exposed to the public internet without requiring visitors to join a private network. Both tools also support end-to-end encryption: traffic is not decrypted until it reaches the local device, so intermediate servers cannot read normal communication content. OpenTunnel also provides an SDK, allowing developers to integrate public network access features directly into their own applications. OpenCode has completed integration with OpenTunnel and plans to launch the remote pairing feature in its official version on October 9. At that time, users will be able to connect to OpenCode running on their computer via a mobile device using a one-time link or QR code. However, public links are not private connections—anyone can attempt to access the public URL, so sensitive services still require authentication. The community also notes that the operator holds domain and certificate issuance privileges, meaning they could theoretically issue additional certificates. Dax acknowledged that users still need to trust the operator, adding that users can deploy their own intermediate servers.
