The record

Purpose: LibreSpeed is a very lightweight JavaScript speed test using XMLHttpRequest and Web Workers.
Measurements: The test measures download, upload, ping, and jitter.
Browser support: The project states that IE11, current Edge, Chrome, Firefox, Safari, and mobile browser versions are supported.
Optional telemetry: Telemetry and results sharing are optional features.
Multiple servers: LibreSpeed can automatically choose among multiple test points using the one with the lowest ping.
Stability test: A standalone stability test reports current, average, minimum, and maximum latency, jitter, failed-request percentage, threshold alerts, and CSV export.
External targets: The stability test can target the local backend, configured test points, or Google, Cloudflare, and Apple.
Database integrations: Optional result storage supports MariaDB, MySQL, Microsoft SQL Server, PostgreSQL, and SQLite.
Client options: The project provides an Android client template, a command-line client, and a .NET client library distributed through NuGet.
Backend options: Go and Rust implementations are available, while the Node.js implementation is partial and currently not recommended.
Docker: A Docker image is built weekly with updated ipinfo data and the latest PHP security patches, and the project recommends the latest image.
Privacy data: The official demo says telemetry may store test ID, time, results, IP address, ISP, approximate location, user agent, browser locale, and a test log.
Privacy disclosure: The official privacy policy says collected data is not disclosed to third parties and can be deleted when the test ID or IP address is provided.
