Build dashboards for any device. Instantly.

Stream telemetry, plot sensor data, and monitor systems in real time. No custom frontend code or locked-in formats. Works with serial, MQTT, Bluetooth LE, or network sources.

Serial Studio is an open-core, cross-platform telemetry dashboard and real-time data visualization tool. It supports input from serial ports, Bluetooth Low Energy (BLE), MQTT, and TCP/UDP sockets, allowing data acquisition from embedded devices, external software, and networked services.

Serial Studio runs on Windows, macOS, and Linux. It is suited for telemetry monitoring, sensor data analysis, and real-time debugging in educational, hobbyist, and professional environments.

Making the Network Visible.

sFlow® is an industry standard technology for monitoring high speed switched networks. It gives complete visibility into the use of networks enabling performance optimization, accounting/billing for usage, and defense against security threats.

IP accounting iconoclasm.

pmacct is a small set of multi-purpose passive network monitoring tools. It can account, classify, aggregate, replicate and export forwarding-plane data, ie. IPv4 and IPv6 traffic; collect and correlate control-plane data via BGP and BMP; collect and correlate RPKI data; collect infrastructure data via Streaming Telemetry. Each component works both as a standalone daemon and as a thread of execution for correlation purposes (ie. enrich NetFlow with BGP data).
