What it is

LibreSpeed is a self-hosted, open-source speed test application built in JavaScript with XMLHttpRequest and Web Workers, measuring download, upload, ping, jitter, and optional IP/ISP geolocation. It replaces proprietary speed test tools with a lightweight, browser-native implementation deployable on PHP, Node, or multiple backends without requiring Flash, Java, or WebSockets. Monolithic single-deployment structure: frontend/ contains HTML, CSS, and JavaScript UI assets; backend/ holds PHP scripts for data collection and geolocation (country_asn.mmdb, geoip2.phar); root-level speedtest.js and workers (speedtest_worker.js, stability_worker.js) drive the core test logic. Two index files…

Start here

Open these first:

• speedtest.js — Main entry point and orchestrator for speed test execution; coordinates download, upload, ping, and jitter measurements.
• speedtest_worker.js — Web Worker implementation that runs bandwidth tests off the main thread to prevent UI blocking.
• frontend/index.html — Primary UI entry point that loads the modern speed test interface and initializes the test framework.
• backend/garbage.php — Server-side endpoint that generates test data streams for download/upload bandwidth measurement.
• config.json — Central configuration file that defines test parameters, server locations, and behavioral settings.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/librespeed/speedtest.git
cd speedtest
npm install
npm run validate  # Format check and linting

Then serve the repository root via a web server (e.g., php -S localhost:8000 for PHP, or a static server for the frontend). Verify package.json requires Node >=14.0.0.

Daily commands:

Development with npm: npm run test:e2e or npm run test:e2e:headed (Playwright). Validation: npm run validate (format check + eslint). Formatting: npm run format to auto-fix style. Docker: `npm ru…

…shortened for this brief.

Key cautions & unknowns

• LGPL-3.0 is copyleft — check downstream compatibility
• Scorecard: default branch unprotected (0/10)
• Database optional but configurable: results/ folder stores schema files; if enabled, database URL and credentials must be set (no evidence of env var schema in repository_data—verify results/ directory). **GeoIP…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
