OpenCode co-founder Dax Raad has released OpenTunnel, an open-source tunneling tool that generates public HTTPS links for websites, APIs, or OpenCode services running on a computer.
Remote access for OpenCode running on a home computer
The tool is meant to let users keep OpenCode running on a machine at home and still connect to it from a phone while away, so they can continue managing AI coding tasks without setting up a public IP address or router port forwarding.
According to the description, the feature works in a similar way to Tailscale Funnel. Both can expose local services to the public internet, and visitors do not need to join a private network to access them.
Encryption model and developer support
OpenTunnel and Tailscale Funnel both support end-to-end encryption. Traffic is decrypted only after it reaches the local machine, so relay servers cannot read the contents of normal communications.
OpenTunnel also includes an SDK, allowing developers to add public access capabilities directly into their own applications. OpenCode has already completed the integration and plans to launch remote pairing in its production release on Oct. 9. Users will then be able to connect from a phone or other device to OpenCode running on a computer through a one-time link or a QR code.
Public links still require access controls
The announcement also makes clear that a public link is not the same as a private connection. Anyone can try to access a public URL, so sensitive services still need authentication.
Community members also pointed out that the operator controls the domain name and certificate issuance rights, which means it could theoretically issue another certificate. Dax said users still need to trust the operator, while adding that they can also deploy the relay service themselves.
