Fully Exam Kiosk vs OpenLock

Fully Exam Kiosk locks an Android device to a configured exam website during an online exam. Students can use the quiz site and its features, while the kiosk blocks access to other websites, apps, and device features; it also blocks app switching and screen capture. It supports learning management systems that work with Safe Exam Browser, including Moodle. Teachers can prepare configurations and distribute them as FEK files, permalinks, or QR codes, and can import Moodle Safe Exam Browser configuration files (.seb). Other exam websites can be used if their URL is kept secret, since students could otherwise open the site in another browser. The app can run on school-owned or student-owned devices. Safe kiosk mode may require show-on-top and usage-data access permissions. Kiosk mode can end through a configured quit link, a password-protected quit button, or a device reboot. The plan is free, with free access stated to last at least until the end of 2027. The maker notes that exam-site speed, bugs, and user experience are outside its control.

OpenLock is a free, open-source lockdown exam browser built natively for Linux. It aims to provide Safe Exam Browser-style controls, but the project states that it is not exam-ready because SEB key derivation is not byte-exact and the LMS handshake currently fails. It parses .seb files and sends Browser Exam Key and Config Key headers, although those keys do not yet match an LMS handshake. Kiosk mode uses fullscreen takeover through X11 or Wayland/Cage. A process guard monitors and terminates prohibited software such as screen recorders, virtual machines, and remote desktop tools. Input controls block shortcuts including Alt+Tab, Alt+F4, Ctrl+C, and PrintScreen, while browser hardening disables developer tools, downloads, right-click, console access, and drag-and-drop. Security measures include URL filtering, cgroups v2 isolation, VM/debugger/hypervisor detection, optional self-hash checks, and an off-the-record profile. Moodle, Canvas, and Blackboard adapters are listed but not validated live.
