The Indy Project is a Open Source group. The Indy Project maintains several active Open Source projects which have evolved from the original Internet Direct (Indy) project. 

Indy.Sockets is an open source blocking socket library that supports clients, servers, TCP, UDP, raw sockets, as well as over 100 higher level protocols such as SMTP, POP3, NNTP, HTTP, and many more. Indy.Sockets is available for C#, C++, Delphi, Visual Basic.NET, any .NET language, and Kylix. The Indy.Sockets FCL build is a managed assembly and is compatible with the Microsoft .NET framework, and Mono. 

Indy.Docs is a volunteer effort to maintain and improve documentation for the Internet Direct (Indy.Sockets) component suite. 

Participation in the Indy Documentation project is open to anyone with a little time, and a little knowledge of the Indy component suite. While programming knowledge is useful, it is not required. This makes the Indy Documentation project a great way for anyone to contribute to the success of Indy, and to have their work read by an ever-increasing number of Indy users. 

Bubelen is a system for building and maintaining bubbles. A bubble is a piece of code for testing, developing, profiling, debugging, and stress testing. Bubbles are similar to boxes which are used in box testing (sometimes also referred to as unit testing), however bubbles are not designed with the only goal being testing. 

Indy.Data is a new project that provides a very unique data access layer in C# for ADO.NET. 

Indy Soap is a Open Source Library for implementing Web Services using Borland environments. IndySoap is not tied to Indy sockets for transport services, though Indy based transport services are included.
