System Monitor component for ESP-IDF: heap and task statistics, plus a framed stream service (MonitorService) that serves them over USB / WebUSB / Web Serial
Heaptop is an htop-like memory monitor for ESP-IDF over the serial console: what is used and free per heap region and per task, health checks (free memory, fragmentation, stack margins, leak suspects, failed allocations), a clear command for fresh measurement windows, CPU stress for benchmarks, and a JSON Lines stream.
