LibreSpeedy

LibreSpeedy is an Android client for self-hosted LibreSpeed servers. It measures ping, jitter, download, and upload with a privacy-first design and a benchmark-tuned network engine.

This is a personal free-time project maintained by a single developer. There is no organisational backing and no guaranteed response SLA. Bug reports and contributions are welcome, but please set expectations accordingly.

Why LibreSpeedy Built specifically for LibreSpeed PHP backends. Separate IPv4 and IPv6 test paths. One-way state flow with predictable UI updates. High-throughput engine based on OkHttp (HTTP/1.1, tuned dispatcher/pool settings). No analytics, no tracking SDKs, and minimal permissions.

Feature Highlights Ping + jitter measurement. Download and upload throughput tests with live metric cards. Live bandwidth chart with adaptive y-axis scaling. Protocol-overhead adjusted throughput display (raw + calculated values in state/tests). Reachability checks for both IPv4 and IPv6 before test start. Automatic test stop and re-check when Android reports real network transitions. Public server list — browse and select from the official librespeed.org sponsored servers, sorted by ping; each server shows its country flag resolved offline from the bundled DB-IP Country Lite database. Your Current IPs card — shows the device's active IPv4/IPv6 addresses with a country flag and one-tap clipboard copy. In-app language switcher — 10 languages (EN, DE, ES, FR, PT, IT, RU, ZH, JA, TR), accessible from the About screen (Android 13+).
