A modular and distributable performance harness for load testing application servers. Developed in java and designed in the same spirit as JUnit (www.junit.org).

LogiTest is a suite of applications to aid in the testing of web sites and web based applications. Applications in the suite include: LogiTest for functional and regression testing, LogiMonitor for real-time monitoring, and LogiLoad for load testing.

E-Mail monitoring, benchmarking and load testing tool with integrated web UI.

Metatest is an integration and load testing framework. It's designed to run different test engines, run tests in serial or parallel, retarget tests (e.g. test DEV, then test UAT), vary test load, support continuous integration, and more!

Renders and aggregates other web services into static HTML monitoring output. Also implements simple and dynamic testing of web based applications using mechanize. Includes Basic authentication, and ADFS authentication for web service testing. Custom authentications can be implemented very easily with python programming. Implements PhantomJS rendering for Javascript/HTML5 dynamic web pages. Requires python3

SoaBox lets you create a virtual version of your SOA environment. Clients (WS-Webservices,RESTful, JMS, HTTP, FTP, Filesystem, POJOs/Custom Code), servers (HTTP/Endpoints) and data (XML, SOAP, CSV, etc). It's written in Java and runs with JBoss 5.x and 6.x

The SoapUI download has moved to https://www.soapui.org/downloads/soapui/source-forge.html With more than 9 million downloads SoapUI is the de-facto standard for REST and SOAP API functional, security and performance testing.

Performance and load testing framework. We aim to create a testing tool for web applications that can simulate large numbers of concurrent users without mucking around with threads, and thus allow us to perform rate-based testing.

A community-developed, free, open source, microservices API automation and load testing framework built using JUnit core runners for Http REST, SOAP, Security, Database, Kafka and much more. Zerocode Open Source enables you to create, change, orchestrate and maintain your automated test cases declaratively with absolute ease. Zerocode makes it easy to create and maintain automated tests with absolute minimum overhead for REST,SOAP, Kafka Real Time Data Streams and much more. It has the best of best ideas and practices from the community to keep it super simple, and the adoption is rapidly growing among the developer/tester community. Zerocode is a modern lightweight, simple and extensible open-source framework for writing test intentions in simple JSON or YAML format that facilitates both declarative configuration and automation. Put simply, Zerocode alleviates pain and brings simplicity to modern API automation.

hammer is a Http load testing tool for Unix/Linux platforms. hammer reads scripts of XML that describe the load tests. hammer is implemented in C++ using Xerces-C and Commoncpp2.

jLlama is a desktop application to monitor servers over SSH. Any figure retrieved from the command line can be polled and graphed in real time. Out of the box, jLlama can graph CPU and Memory usage for Linux and Solaris servers.

The jload framework enables developers to create repeatable load test cases. The framework will then execute these cases and generate reports and graphs showing the execution times and characteristics.

A Java Web crawler: multi-threaded, scalable, with high performance, extensible and polite. It can be used to crawl and index any web or enterprise domain and is configurable through a XML configuration file.
