SpeedTest by OpenSpeedTest™ - Free & Open-Source HTML5 Network Performance Estimation Tool.

SpeedTest by OpenSpeedTest™ is a Free and Open-Source HTML5 Network Performance Estimation Tool Written in Vanilla Javascript and only uses built-in Web APIs like XMLHttpRequest (XHR), HTML, CSS, JS, & SVG. No Third-Party frameworks or libraries are Required. All we need is a static web server like NGINX. I started this project in 2011 and moved to OpenSpeedTest.com dedicated Project/Domain Name in 2013.

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.

Why OpenSpeedTest

Secure by Design.

OpenSpeedTest contains Only STATIC Files like HTML,CSS & JS.

So you don't need to worry about Security Updates or Hidden Exploits that may compromise your secure environments.

Lightweight, High Performance.

OpenSpeedTest is written in Vanilla JavaScript. No Third-Party frameworks or libraries were used. SpeedTest script file size is under 8kB gzip. The unexpected side effect of using Vanilla JavaScript is High Performance.

Run a speed test from Any Device.

• Accept, GET, POST, HEAD & OPTIONS, Response 200 OK.

• Accept, POST to Static Files, Response 200 OK.

• client_max_body_size, 35 Megabytes or more.

• Timeout greater than 60 seconds.

• Disable Access logs for Increasing server performance.

• Improve Time to First Byte (TTFB)

• Warning! If you run it behind a Reverse Proxy, you should increase the post-body content length to 35 megabytes.

• Supports HTTP2 & HTTP3.

• HTTP1.1 is recommended for achieving maximum performance.

• You Should Follow our Nginx Config.

Or, You can use OpenSpeedTest-Server.

OpenSpeedTest-Server is available for Windows, Mac, Linux, Android, iOS & Docker.

Fully Optimized and ready to use applications.

New features:

1. Stress Test. (Continuous Speed Test)

To enable the stress test. Pass Stress or S keyword as a URL parameter.

http://192.168.1.5?Stress=Low

After the STRESS or S keyword, you can specify the number of seconds you need to run the StressTest in seconds, or preset values such as Low, Medium, High, VeryHigh, Extreme, Day, and Year. Will run a speed test for 300,600,900,1800,3600,86400,31557600 seconds, respectively. Also, you can feed the first letter of each parameter and its values.

http://192.168.1.5?S=L

S=L is the same as passing Stress=low

Or you can specify the number of seconds eg:5000 directly without any preset keywords.

http://192.168.1.5?Stress=5000

2. Run a speed test automatically

Run a speed test automatically on page load.

http://192.168.1.5?Run

Run a speed test automatically after a few seconds.

http://192.168.1.5?Run=10 or http://192.168.1.5?R=10

You can pass multiple keywords, and it's not Case-Sensitive.

http://192.168.1.5?Run&Stress=300 OR http://192.168.1.5?R&S=300

This will start a speed test immediately and run for 300 seconds in each direction. That is 300 seconds for download and 300 seconds for upload.

3. Save results to a Database

Edit Index.html

var saveData = true;

var saveDataURL = "//yourDatabase.Server.com:4500/save?data=";

4. Add multiple servers. The app will choose one with the least latency automatically.

Edit Index.html

var openSpeedTestServerList = [

{"ServerName":"Home-Earth", "Download":"/downloading", "Upload":"/upload", "ServerIcon":"DefaultIcon"},

{"ServerName":"Home-Mars", "Download":"/downloading", "Upload":"/upload", "ServerIcon":"DefaultIcon"},

{"ServerName":"Home-Moon", "Download":"/downloading", "Upload":"/upload", "ServerIcon":"DefaultIcon"}

];

5. Disable or change Overhead Compensation factor.

http://192.168.1.5?clean

Overhead Compensation factor, This is browser based test, Many Unknowns. Currently 4%. That is within the margin of error.

You can pass Clean or C as a URL Parameter and reset Overhead Compensation factor to Zero or set any value between 0 and 4. 1 = 1% to 4 = 4%.

Clean will not accept values above 4, so Compensation is limited to maximum 4%.

6. Change the default limit of 6 parallel HTTP connections to the Server.

http://192.168.1.5?XHR=3 OR http://192.168.1.5?X=3

Allow the user to Change the default limit of 6 parallel HTTP connections to the Server. XHR will Accept values above 1 and max 32

pass XHR or X as a URL Parameter.

7. Select a different server to run a speed test.

http://192.168.1.5?Host=http://192.168.55.1:90 OR http://192.168.1.5?h=http://192.168.55.1:90

Pass Host or H as a URL Parameter.

HOST will Accept only valid HTTP URLs like http://192.168.1.10:3000 or https://yourHost.com.

8. Select and run one test at a time, DOWNLOAD, UPLOAD, or PING.

http://192.168.1.5?Test=Upload OR http://192.168.1.5?T=U

TEST Allow the user to select and run one test at a time, Download, Upload, or Ping.

Pass Test or T as a URL Parameter.

9. Set a PingTimeout dynamically by passing Out or O as a URL Parameter

http://192.168.1.5?Out=7000 OR http://192.168.1.5?O=7000

If Server not responded within 5 Seconds for any requests we send ('pingSamples' times)

We will show Network Error, You can change the limit here.

In milliseconds, if you need to set 6 seconds. Change the value to 6000.

10. Set the Number of ping samples by adding Ping or P as a URL Parameter

http://192.168.1.5?Ping=500 OR http://192.168.1.5?P=500

More samples = more accurate representation. Ping = 500 will send 501 requests to server to find the accurate ping value. Take a look at index.html, you can set a custom ping sample size, threads, upload data size etc.

Self-hosted (On-Premise) / (Docker Image/Source Code)

For Headless large-scale deployments.

You have two options here. If you need a custom deployment, use our source code along with a web server of your choice. I prefer Nginx, and you can find my Nginx Configuration here. Or you can use our docker image. You can deploy it on your LAN/WAN with or without an active internet connection.

This is docker implementation using nginxinc/nginx-unprivileged:stable-alpine. uses significantly fewer resources.

• NGINX Docker image that runs NGINX as a non root, unprivileged user.

Docker install instructions:

Install Docker and run the following command!

sudo docker run --restart=unless-stopped --name openspeedtest -d -p 3000:3000 -p 3001:3001 openspeedtest/latest

Or use docker-compose.yml

version: '3.3'
services:
    speedtest:
        restart: unless-stopped
        container_name: openspeedtest
        ports:
            - '3000:3000'
            - '3001:3001'
        image: openspeedtest/latest

• Warning! If you run it behind a Reverse Proxy, you should increase the post-body content length to 35 megabytes.

• Follow our Nginx Config.

Now open your browser and direct it to:

A: For HTTP use: http://YOUR-SERVER-IP:3000

B: For HTTPS use: https://YOUR-SERVER-IP:3001

Container-Port for http is 3000

If you need to run this image on a different port for HTTP, Eg: change to 80 = -p 80:3000

Container-Port for https is 3001

If you need to run this image on a different port for HTTPS, Eg: change to 443 = -p 443:3001

Setup Free LetsEncrypt SSL with Automatic Certificate Renewal

Requirements

• PUBLIC IPV4 and/or IPV6 address.
• A domain name that resolves to speed test server's IP address.
• Email ID

The following command will generate a Let's Encrypt certificate for your domain name and configure a cron job to automatically renew the certificate.

docker run -e ENABLE_LETSENCRYPT=True -e DOMAIN_NAME=speedtest.yourdomain.com -e USER_EMAIL=you@yourdomain.pro --restart=unless-stopped --name openspeedtest -d -p 80:3000 -p 443:3001 openspeedtest/latest

Or use docker-compose.yml

version: '3.3'
services:
    speedtest:
        environment:
            - ENABLE_LETSENCRYPT=True
            - DOMAIN_NAME=speedtest.yourdomain.com
            - USER_EMAIL=you@yourdomain.pro
        restart: unless-stopped
        container_name: openspeedtest
        ports:
            - '80:3000'
            - '443:3001'
        image: openspeedtest/latest

How to Use Your Own Secure Sockets Layer (SSL) Certificate, Self-Signed or Paid?

Requirements

• Folder with your Certificate, Self-Signed or Paid.

• Rename .cet file and .key file to nginx.crt & nginx.key

  The folder needs to contain:

• nginx.crt

• nginx.key

sudo docker run --restart=unless-stopped --name openspeedtest -d -p 3000:3000 -p 3001:3001 openspeedtest/latest

To mount a folder with your own SSL certificate to this Docker container, append the following line to the above command:

-v /${PATH-TO-YOUR-OWN-SSL-CERTIFICATE}:/etc/ssl/

I am adding a folder with nginx.crt and nginx.key from my desktop by using the following command.

sudo docker run -v /Users/vishnu/Desktop/docker/:/etc/ssl/ --restart=unless-stopped --name openspeedtest -d -p 3000:3000 -p 3001:3001 openspeedtest/latest

Or use docker-compose.yml

version: '3.3'
services:
    speedtest:
        volumes:
            - '/Users/vishnu/Desktop/docker/:/etc/ssl/'
        restart: unless-stopped
        container_name: openspeedtest
        ports:
            - '3000:3000'
            - '3001:3001'
        image: openspeedtest/latest

Advanced Configuration Options

• Container Port Configuration

To enable port changes, set the CHANGE_CONTAINER_PORTS environment variable to "True" and provide appropriate values for the following variables.

CHANGE_CONTAINER_PORTS=True

HTTP_PORT=3000

HTTPS_PORT=3001

• Set User

SET_USER=101

• Only Allow CORS Request from listed domains.

ALLOW_ONLY=domain1.com;domain2.com;domain3.com

• SET_SERVER_NAME Display the server name on the UI.

SET_SERVER_NAME=HOME-NAS

Docker images run better on Linux Platforms, including your NAS. But if you install docker on macOS or Windows, you may see poor performance. I asked this on Docker forums, and they told me macOS and Windows support is for Development purposes only. For Production, you need to use any Linux Platform.

The same Story goes for Windows NGINX. Nginx uses only one worker even if you specify n number of worker processes. They will show in Task Manager, but the system will only use one. I got this information directly from the Nginx website.

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 worst, 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 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 including unwanted extensions installed. From my experience, only keep the one you are going to use every single day. Extension 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.
