An application for launching HTML5 Network Speed Test Server. You can test download & upload speed from any device within your network with a web browser that is IE10 or new. How to use OpenSpeedTest Network Speed Test Server? You need two devices in between your WiFi router. Run OpenSpeedTest Server App on one device and connect directly to your router, if it's a wireless device, put it within 1.5 meters. Navigate to the URL shown in OpenSpeedTest Server App from the second device. Now you can test download and upload speed from other devices on your network to the device with OpenSpeedTest-Server. Important Info : - Use the Fastest Device Available with you for Server. - Use 5Ghz WiFi Band for Maximum Performance. - Do not minimize this Application or run in background. When you run a speed test. Are you experiencing slow internet usage? Endless buffering? Probably due to a congested wifi channel. You may need to change your WiFi router location or adjust your router settings. OpenSpeedTest-Server is here to help you to improve your internet experience. Test Your WiFi (Wireless) or Ethernet Connection (Wired Connection) and Fix your local network before pointing fingers towards your ISP for a slow and sluggish internet experience. Introducing HTML5 Network Speed Test Server for iOS. For Headless/large-scale deployments, Docker image and Source Code are available. Why do you need to Create Your Own SpeedTest Server? You can run OpenSpeedTest Server in your Home Lab, Office Server or Cloud Server. So that you or employees who work from home can run a speed test to your office and make sure they can run everything smoothly. Choosing between ISP1 & ISP2. Sometimes your ISP2 is Faster than ISP1 when you test your speed on popular speed test sites. But when you connect to your Home/Office/Cloud, that slower connection may perform better. The only way to find out is to run a speed test against your infrastructure. Troubleshooting network issues. It is common even when your Internet connection is working fine, but some of the devices in your network may experience trouble getting decent connectivity to the internet. The issue might be the wrong VLAN ID or Faulty Switch. If you run a Local network speed test, you can find and fix these issues easily. Before you add a repeater. Most repeaters will reduce your network speed by 50%, so if you put it far away, it will perform worse, and if you put it too close, you will not get enough coverage if you run a Local Network speed test. Depending on the application requirements, you can decide exactly where you need to put your repeater. Browsing experience. Many useful browser extensions are out there that we all know and love. But some of them are really slowing you down for a few seconds per page you visit. You may see good performance when you test your network performance via File Transfer or Command-line utilities, but you may experience poor performance when browsing the internet. This is due to a bad browser configuration that includes unwanted extensions installed. From my experience, only keep the one you are going to use every single day. Extensions that you may use once in a while should be removed or disabled for maximum performance. If you see poor performance, try OpenSpeedTest from Private Window or Incognito Window. This tool can be used to check the browser performance and impact of Extensions on your browsing experience. No client-side software or plugin is required. You can run a network speed test from any device with a web browser that is IE10 or newer.

iPerfman measures network performance between your device and a compatible iperf3 server. Run TCP or UDP tests on iPhone, iPad and Mac. The free version allows three tests per day; Pro unlocks unlimited tests and advanced controls. Measure and investigate: - Test upload, download or both directions, with separate results for each direction. - Follow throughput in live charts. View UDP jitter and packet loss, TCP retransmissions, and round-trip time when those measurements are available. - Save completed tests with their configuration and interval results, then rerun a test or review its history. - Choose an IPv4/IPv6 interface when running a server, or listen on all interfaces. Unlock Pro with a monthly or yearly subscription, or a one-time Lifetime purchase. Pro adds unlimited daily tests, advanced iperf3 parameters, comparison of saved results, and full report export. The yearly subscription includes a seven-day free trial for eligible customers. Existing Lifetime purchases remain valid. iPerfman uses iperf3 3.21 through IperfSwift. A compatible server or second device is required for a network test; this is not an internet speed-test service. The Apple TV app uses a separate interface and has a different feature set.

Verdict
The clearest difference is in-app purchases: OpenSpeedTest at none against iPerfman's 2. OpenSpeedTest also leads on ratings volume (13 vs 4) and iOS requirement (12.0 vs 15.0). iPerfman's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (75% vs 57%). On price, rating, ads and device support there is nothing between them.

Both are free to download. iPerfman sells 2 one-off in-app purchases. OpenSpeedTest asks for nothing beyond the download.
OpenSpeedTest holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 13 and 4 respectively. Written reviews complicate that: 57% of OpenSpeedTest's written reviews are positive against 75% of iPerfman's, so the app with the better star average is not the one people write more warmly about.
OpenSpeedTest ships an update every 3 months, iPerfman every 3 weeks. The most recent releases landed on October 15, 2026 and October 24, 2026 respectively.
