Overview
OpenSpeedTest is a browser-based network performance test implemented with static HTML, CSS, JavaScript and standard web APIs. It can be hosted on an internal web server to measure download speed, upload speed, latency and jitter without installing a client application. Results still depend on browser behavior, server capacity, Wi-Fi conditions and the path between the test device and server.Best for
Home users, support teams and network administrators who need a browser-accessible speed test on a controlled server or local network.Pricing and availability
The software is available under an open-source license. Infrastructure, app-store distribution, hosted services and professional support may still create costs.Platforms and integrations
Available through: web, windows, macos, linux, ios, android.The static application can be served by a standard web server and accessed from modern desktop, mobile and embedded browsers. Container and server packages are available through project channels.
Privacy and security
A private deployment reduces reliance on a third-party test site, but logs, reverse-proxy settings and public exposure remain the operator's responsibility. Do not treat a single browser test as proof of ISP or application performance.Key strengths
- No client installation required
- Static browser application with simple hosting
- Useful for internal and self-hosted network testing
Key limitations
- Measurements depend on the browser and test server
- A local test does not measure the full internet path
- High-speed links require adequate server and network capacity
