As answered by people managing HackerRank and Jonot.
Jonot's answer:
Jonot combines easy, hardware-independent deployment with reliable queue management for real-world service locations. Businesses can use their existing tablets, computers and displays instead of purchasing proprietary equipment, while customers join by QR code, web link or self-service kiosk without downloading an app or creating an account.
Unlike many cloud-only systems, Jonot can continue calling tickets over the local network during internet disruptions. It also brings together multilingual customer journeys, custom branding, live lobby displays, feedback collection and integrations in one straightforward platform with transparent pricing.
