Harbor Scale (formerly Telemetry Harbor)
Harbor Scale streams sensor and server metrics into managed Grafana dashboards. You point ESP32 boards, Linux hosts, or Docker containers at the Harbor API and get live charts without provisioning InfluxDB or writing YAML configs yourself.
DIY Grafana stacks take hours to wire up and cost real developer time each month. Harbor Scale advertises sub-60-second onboarding with pre-connected Grafana, batch ingestion up to 1,000 points per call on the Pro plan, and a Python SDK you can start with four lines of code. The free tier still includes managed Grafana access, which most cloud monitoring vendors charge extra for.
It targets makers shipping ESP32 or LoRaWAN hardware, DevOps teams tired of maintaining Telegraf configs, and anyone who wants Grafana visuals without running the backend. Plans run from a free 50K-point tier through $9 and $29 monthly tiers with longer retention and higher batch limits.
