Used by Java programmers for code exploration, navigation, design visualization and communication, development monitoring, this Eclipse plugin is a highly configurable UML class diagram generator. Its unique properties are:
1. It solves the problem of reverse engineered UML class diagrams containing too much information to be of any practical use by only showing Java elements belonging to user-defined categories one at a time. For example, testing, persistence, user interface, or any other specifyable category.
2. It is refactoring friendly. A class will not disappear from a diagram if it is renamed or moved to another package.
3. It gives precedence to Java as the modeling language above UML. For example, exceptions, Javadoc and Java modifiers are shown. Even Eclipse errors and warnings are shown.

JOSIT (Java Observation Simulation Inspection Toolkit) is an open Application Programmer's Interface for instrumenting applications written in the Java programming language. JOSIT seamlessly integrates with any Java application written using Sun Microsystem's standard library of Java graphical objects. JOSIT observes user actions, inspects the state of objects and scripts graphical events. Tools written in other programming languages may communicate with JOSIT via sockets.

The Persevere project is an open source set of tools for persistence and distributed computing using intuitive standards-based JSON interfaces of HTTP REST, JSON-RPC, JSONPath, and HTTP Channels. The core of the Persevere project is the Persevere Server.

STAN encourages developers in visualizing their design, understanding code, measuring quality and reporting design flaws. STAN supports a set of carefully selected metrics, suitable to cover the most important aspects of structural quality. Special focus has been set on visual dependency analysis, a key to structure analysis. STAN provides its own perspective, showing various dependency graphs, ranking metric violations, generating HTML reports, etc.

The first pure play provider of open source data integration software, Talend offers open, innovative and powerful data integration solutions, used primarily for integration between operational systems, ETL, and migration by organizations of all sizes.

.NetSpec is a small test extension framework for the Visual Studio Testing Framework. Its main goals are:
* Allow users to write tests in an RSpec like syntax more in terms with Behaviour Driven Developement (BDD)
* Make tests easier to read
* Integrate with TFS team build and Visual Studio test view

Eclipse and EMF template-based system for source-code generation from UML models. Acceleo is easy to use. It provides "off the shelf" generators (JEE, .Net, Php...) and template editors for Eclipse.

AceRP is a web-based system tailored for the needs of professional software, game development companies and other large and SMEs willing to manage global teams and go beyond the limitations of typical outsourcing model.

AcornDB is a high performance, small footprint, transactional object oriented database written entirely in Java. It stores data in the application's native format, so no runtime data translation is required. AcornDB supports full ACID transactions and recovery. It provides an easy-to-use interface like query-by-example, object query API, automatic class schema recognition allowing programmers to store and retrieve information quickly, simply and reliably.

Adminer (formerly phpMinAdmin) is a full-featured MySQL management tool written in PHP. Conversely to phpMyAdmin, it consist of a single file ready to deploy to the target server.
