LibreSpeed is a self-hosted HTML5 network speed test tool used to measure download and upload speeds, ping, and jitter. It operates as a private server for measuring network performance without relying on third-party services.
The system functions as a multi-backend performance tool that executes network tests across different server environments and geographic locations. It supports both PHP and Node.js backends and acts as a network telemetry collector by recording connection metadata and performance metrics into a database for historical analysis and reporting.
The tool provides capabilities for network diagnostics, including measuring performance and tracking connection metadata such as internet service providers and IP addresses. It also enables multi-region network analysis by running tests from multiple locations to compare connectivity across different regions.
