As answered by people managing Mattermost and TriggerDeck.io.
TriggerDeck.io's answer:
TriggerDeck does not publicly disclose customer names at this stage.
TriggerDeck.io's answer:
Teams should choose TriggerDeck when they want a mobile-first Zabbix experience without giving a third-party backend access to their monitoring credentials. It is designed for fast triage on iPhone, supports multiple servers, and focuses on the workflows operators actually need on the go: active problems, details, hosts, items, charts, dashboards, and optional push notifications. The product is opinionated about security, clear data boundaries, and reducing friction between alert and action.
TriggerDeck.io's answer:
TriggerDeck is built around a strict trust model for Zabbix environments: the iPhone app connects directly to the customer’s Zabbix API. Using our integration service its able to deliver Push notifications from Zabbix directly to your iPhone. This gives teams secure mobile access to problems, hosts, items, charts, and dashboards without introducing a hosted read
TriggerDeck.io's answer:
TriggerDeck is built primarily with Swift 6, SwiftUI, Swift Charts, URLSession with async/await, SwiftData, and Keychain on iOS.
TriggerDeck.io's answer:
TriggerDeck is built for teams that run their own Zabbix-based monitoring environments. The primary audience includes IT operations teams, sysadmins, SREs, DevOps and platform engineers, NOC operators, and technical leads who need secure mobile visibility into infrastructure and incident state while away from their desks.
TriggerDeck.io's answer:
TriggerDeck was created to solve a specific gap in the Zabbix ecosystem: mobile access often becomes less trustworthy when it depends on a hosted proxy or external credential sharing. The product started from the idea that teams should be able to check monitoring data securely from an iPhone and get instant push delivery.
