Shiny Code vs RendrLab

Shiny Code connects to your dev machine over SSH and invokes Claude Code there, so you can kick off tasks, review diffs, and approve tool calls from anywhere — no special setup required. Just your Mac or Linux box, Claude Code, and an iPhone. Your code stays on your machine. Your AI stays productive. And you stay in the loop, whether you're at your desk or away from it.

Rendr is a simple, offline viewer for the React and web files you already keep on your device. Open a folder of your .jsx, .tsx, and .html files through the Files app, and Rendr renders each one in a clean, full-screen preview using a built-in React + web runtime. There is no build step, no setup, and no servers. Everything happens on your device. WORKS WITH YOUR OWN FILES Rendr reads files from a folder you choose through the Files app. It has no catalog and no store, and it downloads nothing; it only shows the files that are already on your device. • Pick any folder and Rendr lists the .jsx, .tsx, and .html files and subfolders inside it • Nested folders are supported, with a tappable breadcrumb so you always know where you are • Search within a folder and across your whole tree • Sort by name or date modified • Smart automatic icons from folder names (plus a custom icon and color for any item) • Pull to refresh to pick up new files • Add files to Rendr from other apps via the share sheet • Universal: iPhone and iPad, with a split view on iPad FULLY OFFLINE AND PRIVATE Files are rendered in a sandboxed runtime that is blocked from all network access. Nothing is uploaded, nothing is downloaded, and nothing phones home. Rendr collects no data: no accounts, no analytics, no tracking. The folder you choose is read only on your device, and the app saves just a secure bookmark and your display preferences locally. GOOD TO KNOW • Rendr is offline by design. Files that try to load remote data or call the network won't fetch anything. Rendr is for previewing self-contained files you already have, not for browsing the web. • It runs a fixed, built-in React + TypeScript + web runtime. Self-contained files render best; files that depend on external packages may not render in full. • Rendr renders your files; it doesn't edit them. Rendr is a focused, private way to preview the React and web files you already keep on your device.
