Build Remote Agent vs TethrX

Build Remote Agent puts your local coding CLI and terminal sessions on the screens you already use. Install the open-source desktop agent (gbr-agent) on Windows, macOS, or Linux. Pair with a short code or camera QR. Swipe between named sessions, inject commands (type or voice), and read colorized terminal output. Your device and PC never connect directly; traffic uses ordinary HTTPS to the product relay. No VPN. No open ports between devices. WHAT YOU GET • Paid app — $13.00 USD one-time (no subscription) • Open-source desktop agent (download from the product website) • Pair with an 8-character code (expires in 10 minutes) or QR • Named sessions from folders, git repos, or local session files • Full-screen chat-style inject UI (sidebar session list on larger displays) • Offline command queue • Voice inject and ANSI color terminal transcript • Optional companion on Apple Watch where available HOW IT WORKS 1.

TethrX is a native, private, independent remote for Grok Build, SpaceXAI's terminal coding agent. Your phone is only a control plane, Grok, its tools, and your code stay on your own machine. TethrX connects to a small open-source bridge you run on your computer. • Watch Grok work in real time — thoughts, commands, file edits, and their output. • Approve or reject every tool call — from the app, or straight from a push notification on your lock screen. • Plan mode — Grok drafts a plan; you review and approve it before it builds. • Review what changed — per-file diffs, commit or discard from your phone. • Queue follow-ups, branch sessions, schedule recurring tasks, dictate messages. • No accounts, no tracking, no third-party servers. Your phone talks only to your bridge, direct, over Tailscale, with certificate-pinned HTTPS. Requires your own Grok Build install (SuperGrok / SuperGrok Heavy / X Premium+) and the TethrX bridge running on your computer (npx tethrx-bridge). Setup takes a couple of minutes. TethrX is an independent client and is not affiliated with, endorsed by, or sponsored by SpaceXAI. "Grok" and "Grok Build" are trademarks of their respective owner.
