KhagaLink

A fast telemetry dashboard and CSV visualizer for embedded systems.

Built for ESP32, STM32, and custom hardware, KhagaLink pairs a React frontend with a Rust backend for smooth serial communication, live telemetry, and large CSV analysis without UI lag.

Maintained by a solo developer. If KhagaLink saves you time or replaces a pile of scripts, a ⭐ helps a lot.

Why it exists

Web tools are fine until the serial stream gets noisy.

KhagaLink stays responsive by moving parsing and heavy lifting into Rust, with an offline-first desktop workflow that holds up in the lab, field, or launchpad.
