PenguiNet is no longer under development.

Thank you

We'd like to thank all past users of PenguiNet. We've taken the decision to stop development.

PenguiNet has always been a spare-time project. As the years passed, our available spare time has decreased. Simultaneously, PenguiNet's development environment (C++ Builder) has become increasingly obsolete. Resurrecting PenguiNet at this point would essentially be a complete rewrite and we have neither the time nor the motivation to do this.

Thank you to our thousands of users over the past 20 years!


The last version of PenguiNet can be downloaded above, along with a suitable keyfile, free of charge.

We may in future make the PenguiNet source code available under an Open Source licence. Doing so will depend on available time. We don't intend to sell the project.

PenguiNet includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit, cryptographic software written by Eric Young (, uses the ZLib compression library by Jean-loup Gailly and Mark Adler, the TinyXml parser, the SpTBXLib package by Robert Lee, and includes elements of the Silk icons set.
