About

RendrLab

Features
Read full description

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.
