Qrystal Uplink is a fully managed, cloud-based watchdog that automatically monitors your entire IoT fleet. The platform eliminates the need for provisioning servers, managing databases, writing custom backends, and developing custom SDKs for IoT monitoring. Devices send heartbeat signals to the platform, and if they miss a check-in, users receive instant alerts.

The platform offers real-time monitoring with configurable heartbeat intervals and instant notifications when devices go offline or miss check-ins. It provides easy integration through simple SDKs and REST APIs that require no complex setup, with native support for ESP32 via ESP-IDF and Arduino, as well as other boards via MicroPython. Multi-channel alerting delivers notifications through email and upcoming channels like Telegram and Slack, allowing users to route notifications to the right team members.

Qrystal Uplink operates through a three-step process: devices are registered with unique tokens, they send regular heartbeat signals to the API with health status, and users receive instant notifications if devices miss heartbeats or report issues when anomalies are detected.

The platform provides infrastructure freedom by handling all server provisioning, scaling, monitoring, and maintenance, allowing users to focus on IoT applications rather than infrastructure. This enables global deployment with zero DevOps overhead.

The product targets IoT developers and organizations managing embedded device fleets who want to monitor device health without building custom monitoring infrastructure. It offers developer-friendly SDKs and is designed for integration into existing IoT infrastructure.
