Our performance testing tools for web applications allow users to test load and stress their online applications from a Linux server. The tools include a web application performance simulator, a web application stress tester, a networking performance tester, and a multi-vendor compatibility testing tool that can take a number of different tests and execute them through multiple browsers. It also includes a file organizer for storage of scripts and simulated data.
As a web developer, online performance testing is a tricky thing. You can use native UI performance tools in your browser to see how fast the page loads, which is great. However, you can’t always control things like users, browsers, and network settings. When you automate your tests, it will be able to consume a real amount of data from a real user’s computer.
Tsung
Tsung is a non-Java-based open source tool to test the performance. It was previously known as IDX-Tsunami. It was launched by Nicolas Niclausse in 2001. It provides a complete testing solution with the help of protocols like web sockets, databases and authentication systems.

Locust
Locust is a Python-based framework which allows you to write scripts in Python language. This tool is very simple to use and you can monitor swarming process from web UI. It is targeted for web applications and web-based services. Using this framework you can test all sorts of performance tests. It has a different approach which is based on events and g-event co-routine. It stimulates many users and executes complex scenarios.
Features of Locust
- Web-based UI which is user-friendly
- Cross-platform
- Creation of test scenarios using Python language
- Scalable
- Easy API testing
- Web-based load monitoring
- Code based scripts
- Power assertion ability
Tauras
Tauras provide an automation friendly framework. You can involve in testing like functional testing and performance testing. You can write the tests in YAML which is readable, edible and simple approach to describe your tests in simple text file. Your team can also describe the tests in YAML or JSON file. It gives you relief from heavy client specific recorders and scripting tools.
Features of Tauras
- Provides abstraction layer
- Fits into your CI or CD pipeline
- Uses YAML which easy to perform code reviews
- Allows more members to contribute in testing
LoadComplete
Easy and affordable performance testing tool. LoadComplete enables you to create and execute realistic load tests for websites and web apps. It automates creating realistic load tests by recording user interactions and simulating these actions with hundreds of virtual users either from your local computers or from the cloud.
LoadComplete helps you check your web server’s performance under a massive load, determine its robustness and estimate its scalability. It also provides detailed metrics and reports that help you gain in-depth insights into infrastructure performance, application behavior, and end-user experience.
System requirements: This tool works on 64-bit operating systems such as Windows XP Professional and Windows 7 or later.
WAPT
Performance Testing tool for websites and intranet applications: WAPT refers to the Web Application Performance tool. These are the scales or analyzing tools for measuring the performance and output of any web application or web related interfaces.
These tools help us to measure the performance of any web services, web applications or any other web interfaces. With this tool, you have the advantage of testing the web application performance under different environments and different load conditions.
WAPT provides detailed information about virtual users and their output to its users during load testing. This is considered to be the most cost-effective tool for analyzing the performance of web services.
The WAPT tool can test the web application on its compatibility with the browser and operating system. It is also used for testing the compatibility with the windows application in certain cases.
WAPT System Requirement: Windows OS is required for this testing tool.
Loadster
Loadster is a desktop-based advanced HTTP load testing tool. The web browser can be used to record the scripts which are easy to use and record. Using the GUI you can modify the basic script with dynamic variables to validate the response.
With control over network bandwidth, you can simulate a large virtual user base for your application stress tests.
After the test, an executed HTML report is generated for analysis. This tool is the best way to identify the performance bottlenecks in your application.
Loadster System Requirements: Windows 7/Vista/XP
k6
k6 is a modern open-source load testing tool that provides an outstanding developer experience to test the performance of APIs and websites. It is a feature-rich and easy to use CLI tool with test cases written in ES5.1 JavaScript and support for HTTP/1.1, HTTP/2, and WebSocket protocols.
“Like Unit testing, for Performance” – is the motto of k6. It provides native Pass/Fail behavior for easy automation and integration into CI pipelines. Additionally, the community has built a browser recorder and converters (JMeter, Postman, Swagger/OpenAPI) to facilitate the test creation process.
k6 runs on Windows, Linux, and Mac OS.
Bees with Machine Guns 
Developed by the Chicago Tribune, this is probably the coolest-sounding performance testing tools on this list.
Bees with Machine Guns describes itself as a utility for arming (creating) many bees (micro Amazon EC2instances) to attack (load test) targets (web applications).
This tool can easily help you load test a site that needs to handle high traffic.
Leverage Amazon EC2
It currently has 6k stars on GitHub.
For enterprise-wide performance testing tools, LoadRunner tends to be one of the most common but many of these open-source tools can get you most of the functionality you need. Also, most of these tools protocols can be used for both performance testing web application and performance testing web services.
Fortio
Fortio is a cool load testing library, command-line tool, advanced echo server and web UI in go (golang).
This tool allows to specify a set query-per-second load and record latency histograms and other useful stats.
Pros
- It’s fast
- Small footprint (3Mb docker image, minimal dependencies)
- Reusable
- Embeddable go library
- Can tecord latency histograms and other useful stats.
It currently has 1.8k stars on GitHub.
Conclusion
With our online tools, businesses can choose to pre-test their application’s performance before you launch, or after your application is live. Slayers also offers tools for businesses who have already launched their application to test the performance at any time. You can even set up automated tests so you know if performance changes need to be made.
