Private Viewer: Ai + Sandbox
Best Sandbox Workspace mobile
Free · Designed for iPad. Not verified for macOS.
Privacy by Architecture
No accounts to create. No analytics running in the background. No cloud sync unless you choose it. Your files stay on your device — iOS sandbox or macOS app container — period.
Offline Rendering Engine
Renders React, JSX, TypeScript, HTML, and CSS without a build server. Babel transpiles at runtime. CDN scripts are cached locally for airplane-mode development.
Code Editor + Versioning
Native editor with syntax highlighting and auto-completion. Git-style save points let you snapshot, diff, and restore — no git required.
3D Model Viewer
Open .usdz, .glb, .gltf, .obj, and .dae files natively on iOS. Rotate, zoom, inspect — no third-party app needed.
Persistent Remote Sessions
Magnum Brain Tuning tier includes tmux-backed SSH sessions to your Mac orchestrator. Sessions survive network disconnects, sleep, and app restarts. Send a task from your phone and get notified when it's done.
