Kiosk vs Kiosk Pro

Kiosk is a free, open-source PDF reader for web, desktop, mobile, and browser extensions. It renders PDFs and offers full-text search with highlighted results, page thumbnails, zoom, and light, dark, and night display modes. Its Chrome extension adds highlighting, underlining, strikethrough, drawing, shapes, and text annotations. The project says PDFs stay on the device, with no telemetry, cloud processing, or account requirement. Android works offline after installation, and the extension release notes also state that offline use is supported. The web app can run locally or be deployed through GitHub Pages as a self-hosted instance. Desktop apps can open PDFs directly and associate Kiosk with PDF files; the extension can intercept PDFs opened in Chrome. The extension supports Chrome 88+, Edge 88+, and Brave, but not Firefox or Safari. The project is released under the MIT License. Its Android release is an early alpha, and the macOS app is ad-hoc signed but not notarized, so Gatekeeper may warn on first launch.

Kiosk Pro is a kiosk browser app for iPhone and iPad that presents interactive web content, PDFs, and video while limiting internet access. It runs on iOS and iPadOS 12.5.6 or later and uses the WebKit browser engine. Kiosk Pro Lite adds a no-code site builder and dashboard for creating and controlling kiosk pages. Basic and higher editions can keep content on the iPad for offline access. URL allowlisting, session reset, and digital signage support are included. Optional Remote Management Server services provide device health reports, usage statistics, alerts, remote content and settings updates, and role-based accounts. Enterprise adds Zapier integration plus JavaScript API connections for thermal printers, external displays, and barcode or QR scanners. Plans include Lite at $5 a month, Basic at $24.99 per device once, Plus at $49.99 per device once, and Enterprise at $99.99 per device once.
