Internet of Things
The cloud-based watchdog for IoT.
Stop building custom backends to track IoT uptime. Qrystal Uplink is a cloud-based watchdog for ESP32 & embedded fleets. We use "fail-closed" logic: if your device goes silent (crash, power loss, freeze), we alert you instantly via Email (as well as Slack, Telegram, etc. in the future). Replace weeks of infrastructure work with 5 minutes of integration: • Officially maintained platform SDKs. • One line of code. • No servers to manage. Focus on your firmware. Let us handle the plumbing.
Qrystal Uplink is a Internet of Things company. It launched on Product Hunt on Jan 18, 2026, with 14 upvotes.
