Deploying Speed Test by OpenSpeedTest

Introduction

OpenSpeedTest is a free, open-source HTML5 network speed test application that runs entirely in your browser without requiring Flash, Java, or any plugins. Unlike commercial speed test services, OpenSpeedTest gives you complete control over your testing infrastructure and ensures your speed test data remains private.

Built with pure HTML5 and JavaScript, OpenSpeedTest measures download speed, upload speed, ping latency, and jitter with accuracy comparable to commercial alternatives. The lightweight nature of the application makes it perfect for self-hosting scenarios.

Key highlights of OpenSpeedTest:

Pure HTML5: No plugins, Flash, or Java required
Privacy-Focused: No data collection or tracking
Accurate Results: Tests up to 10 Gbps connections accurately
Mobile Friendly: Works on any device with a modern browser
No Ads: Clean interface without advertisements
Lightweight: Minimal resource requirements
Customizable: Modify test parameters and appearance
Docker Ready: Official Docker image available
Cross-Platform: Works on any operating system
Open Source: MIT licensed for maximum flexibility

This guide walks through deploying OpenSpeedTest on Klutch.sh using Docker for a private, self-hosted speed testing solution.

Why Deploy OpenSpeedTest on Klutch.sh

Deploying OpenSpeedTest on Klutch.sh provides several advantages:

HTTPS by Default: Secure connections with automatic SSL certificates.

Custom Domains: Use your own domain for branded speed tests.

GitHub Integration: Version control your configuration and deploy updates automatically.

No Third-Party Data: Your speed test results stay private.

Internal Testing: Test speeds between your infrastructure and clients.

Always Available: Speed test service runs 24/7 without maintenance.

Low Resource Usage: Lightweight application needs minimal resources.

Prerequisites

Before deploying OpenSpeedTest on Klutch.sh, ensure you have:

A Klutch.sh account
A GitHub account with a repository for your configuration
Basic familiarity with Docker
(Optional) A custom domain for your speed test

Deploying OpenSpeedTest on Klutch.sh

Create a GitHub Repository

Create a new GitHub repository for your OpenSpeedTest deployment.

Create Your Dockerfile

Create a Dockerfile in your repository:

FROM openspeedtest/latest:latest

# The base image includes everything needed
# OpenSpeedTest runs on port 3000 by default

# Optional: Set custom environment variables
ENV TITLE="My Speed Test"
ENV SUBTITLE="Powered by OpenSpeedTest"

EXPOSE 3000

HEALTHCHECK --interval=30s --timeout=10s --start-period=10s --retries=3 \
  CMD curl -f http://localhost:3000/ || exit 1

Push Your Repository to GitHub

Commit and push your Dockerfile.

Create a New Project on Klutch.sh

Navigate to the Klutch.sh dashboard and create a new project named “speedtest” or similar.

Create a New App

Within your project, create a new app and connect your GitHub repository.

Configure HTTP Traffic

In the deployment settings:

Select HTTP as the traffic type
Set the internal port to 3000

Deploy Your Application

Click Deploy to build and start OpenSpeedTest.

Access Your Speed Test

Once deployment completes, access your speed test at https://your-app-name.klutch.sh.

Using OpenSpeedTest

Running a Speed Test

Navigate to your OpenSpeedTest URL
Click Start to begin the test
Wait for download, upload, ping, and jitter measurements
Review your results

Understanding Results

Metric	Description
Download	Data transfer speed from server to client (Mbps)
Upload	Data transfer speed from client to server (Mbps)
Ping	Round-trip time for packets (milliseconds)
Jitter	Variation in ping times (milliseconds)

Test Parameters

OpenSpeedTest automatically adjusts test parameters based on connection speed:

Low-speed connections: Smaller test file sizes
High-speed connections: Larger test file sizes
Automatic multi-threading for faster connections

Customization

Branding

Customize the appearance with environment variables:

Variable	Description
`TITLE`	Main title displayed on the page
`SUBTITLE`	Subtitle text

Advanced Configuration

For more customization, modify the HTML/CSS/JS files directly by extending the Docker image:

FROM openspeedtest/latest:latest

# Copy custom styling
COPY custom.css /usr/share/nginx/html/css/custom.css

# Copy custom logo
COPY logo.png /usr/share/nginx/html/images/logo.png

Use Cases

ISP Speed Verification

Test actual speeds versus advertised speeds
Document speed issues for support tickets
Track speed changes over time

Internal Network Testing

Test speeds between office locations
Verify VPN performance
Benchmark new network equipment

Customer-Facing Speed Test

Provide customers with your own branded speed test
Test connectivity to your services
Support troubleshooting

Server Performance

Test upload/download speeds to your hosting
Verify CDN performance
Benchmark different cloud regions

Performance Considerations

Accurate Results

For most accurate results:

Run multiple tests at different times
Close other applications during tests
Use wired connections when possible
Consider server location relative to users

Server Capacity

OpenSpeedTest is very lightweight
A single instance can handle many simultaneous tests
Scale resources if serving many concurrent users

Troubleshooting

Test Won’t Start

Clear browser cache and cookies
Try a different browser
Check that JavaScript is enabled

Inaccurate Results

Verify no other applications are using bandwidth
Check for VPN or proxy interference
Test at different times of day

Page Not Loading

Verify deployment is running
Check Klutch.sh logs for errors
Confirm port configuration is correct
