Qrystal Uplink is a fully managed, cloud-based watchdog that automatically monitors your entire IoT fleet. It eliminates the infrastructure nightmare of provisioning servers, managing databases, writing custom backends, and developing custom SDKs for IoT monitoring.

Key features include real-time monitoring with configurable heartbeat intervals and instant notifications when devices go offline or miss check-ins. The platform offers easy integration via simple SDKs and REST APIs 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 routing to team members and integration with incident response workflows.

The platform operates through a straightforward 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.

Benefits include infrastructure freedom by handling all server provisioning, scaling, monitoring, and maintenance with zero DevOps overhead. This allows users to focus on IoT applications rather than infrastructure management.

The product targets IoT developers and organizations managing embedded fleets who need reliable device monitoring without building custom backends. It provides developer-friendly SDKs and supports various IoT platforms.
