Steer Grok Build
from your phone.

Build Remote Agent is the mobile remote for your local Grok Build sessions. Install the free open-source desktop agent on Windows, macOS, or Linux. Pair once. Inject commands. Stream output. Phone and PC never connect directly.

After the new Grok Build interface and API launch on 16 July 2026, remote control of local Grok Build workflows became practical in a way that was not possible before. This app is that remote — not a SpaceX or xAI product.

How it works

Mobile app and gbr-agent both talk to a durable HTTPS mailbox. Phone and PC never open sockets to each other — works on locked-down and corporate networks. Built for Grok Build after the mid‑July 2026 interface / API availability.
