KioskGrid vs Libki

KioskGrid has no write-up on Specifiction yet; its figures are above.

Libki manages time-limited access, reservations, and sessions on networked computers, with a focus on public-access settings such as libraries and school computer labs. Administrators use a web interface to manage users and session time, message or ban users, and see which client computers are available or occupied. Users can take computers on a first-come-first-served basis, reserve them, or use both approaches. The client shows remaining session time and allows early logoff; it can also be set to log off the operating system or reboot when a session ends. Libki supports SIP2 and LDAP single sign-on. SIP2 settings can restrict access using patron status, fees, age groups, or other configured fields, and the manual covers Koha and Evergreen hold notifications. Print management is available for controlled clients or files uploaded to the server. The server is self-hosted; Debian Linux, Ubuntu Server, or Docker are recommended, and Docker requires a separate database server. Clients run on Windows and Linux, though the maker provides a Windows installer and other operating systems require compiling from source. The system is free to download, install, and use. Administrators can configure data retention and deletion, but empty retention settings keep data indefinitely.
