Acrelec vs Porteus Kiosk

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

Porteus Kiosk is a lightweight Linux operating system that limits a computer to browser use and opens a selected homepage at startup. The maker lists public terminals in schools, libraries, cafes, hotels, offices, and tourist centers, as well as digital signage, as uses. It runs on x86_64 PCs, requires at least 2 GB of RAM and 1 GB of storage, and does not support ARM devices such as Raspberry Pi. The hybrid ISO can be installed on writable media including USB drives, hard drives, SSD or eMMC devices, and SD or MMC cards. Browser history is not retained, passwords are not saved, and caches are cleared when the browser closes. Automatic updates are enabled by default; the maker describes a read-only image and startup checks that stop booting if component values differ from registered values. Porteus Kiosk Server can manage up to 1000 clients behind NAT, proxies, or firewalls, but cannot host client updates: clients update from the maker’s domain and need separate subscriptions. A 30-day free evaluation is available. Continued use requires a subscription, starting at €40 per PC per year, excluding VAT, for 1–10 PCs.
