About

TethrX

Features
Read full description

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.

About

Static Server

Turn your iPhone into a pocket-sized Web runtime environment. This app is more than a local-network file server — it is a mobile server that can run full-featured Web tools. The boundaries of modern Web technology have expanded dramatically: many fully-featured tool applications can ultimately be packaged as a set of local files. This app provides exactly such a runtime, letting you load and run these projects directly on your phone — whether you are coding, preparing lessons, planning, or organizing your thoughts, you can put it to use on your phone anytime. Import a compressed package and start a local HTTP service with one tap, and you can load complete build output or ready-made tools directly on your mobile device. Runtime capabilities: • A standard HTTP runtime that fully supports page routing, WebAssembly, IndexedDB local storage, and single-page applications (SPA). • Compatible with the vast majority of Web software that can be compiled into static assets, moving your results into your phone as-is. Compatibility: • Supports the dist, build, out, and static build output directories of mainstream frameworks such as Vue, React, Vite, and Next. • Compatible with the vast majority of WASM applications, such as JupyterLite, letting you use a browser-based Python runtime directly on your phone. • Supports various Web tools such as open-source whiteboards, mind maps, and drawing editors. Convenience and privacy: • Drag-and-drop upload of packages over the local network, no cable needed, no reliance on any cloud server. • All data is stored on the device, usable offline, and your files and code never leave your device. Who it is for: • Developers: verify how build output actually runs on mobile and catch compatibility issues that only surface on phones. • Programming beginners: no need to set up a complex development environment — import an offline coding environment and start learning anytime, anywhere. • Personal users: put ready-made Web tools such as open-source whiteboards, mind maps, and drawing notes into your phone for studying, lesson prep, planning, and organizing thoughts — no coding required to enjoy the convenience of having them ready at hand on mobile. • Teams: on the same local network, other devices can access the Web tools running on your phone. Demo on the spot without carrying a laptop. Whether you are showing a product prototype to a colleague on the high-speed train, running an offline coding environment in class, or using a whiteboard to sort out the flow of a lesson, as long as you have your phone, your Web tools are ready to run anytime. It is more than a simple web viewer — it is a mobile server that runs full-featured Web tools, where coding environments, canvas editors, and all kinds of interactive tools can run locally on your phone.
