Instead of Kiosk
Kiosk alternatives
Kiosk focuses on reading PDFs across web, desktop, mobile, and browser extensions. It supports full-text search with highlighted results, thumbnails, zoom, and light, dark, and night modes; its Chrome extension adds annotation tools. Kiosk is free and open source, processes PDFs on the device, and requires neither telemetry nor an account. The Android app works offline after installation, and the web app can run locally or as a self-hosted GitHub Pages instance.

The main reasons to look elsewhere are platform caveats: the extension does not support Firefox or Safari, the Android release is an early alpha, and macOS may show a Gatekeeper warning. The products below handle webhooks and events rather than PDFs, so they suit a different job. Consider whether event receipt, routing, retries, or delivery matters more than Kiosk’s reading and annotation tools, and weigh each alternative’s destinations, deployment options, retention, and price before switching.
