Speedtest Tracker is a self-hosted internet performance tracking application that runs speedtest checks against Ookla's Speedtest service.
The main use case for Speedtest Tracker is to build a history of your internet's performance so that you can be informed when you're not receiving your ISP's advertised rates.
As far as I can tell https://github.com/henrywhitaker3/Speedtest-Tracker was abandoned. This is meant to be an actively maintained replacement with an improved UI and feature set.
Speedtest Tracker is containerized so you can run it anywhere you run your Docker containers. The install documentation will get you up and running with using Docker or Docker Composer along with choosing a database (MySQL/MariaDB or Postgresql).
FAQs and a full list of planned and completed features can be found in the documentation.
A robust API is planned for a later release but as of v0.11.8 a legacy endpoint /api/speedtest/latest which is used by home lab dashboards like Homepage and Organizr.
