Contributing to the Tunnelblick Project

Tunnelblick is Free Software and is developed and maintained entirely by volunteers. We would love to have your help, too!

Although you can donate money, there are many other ways you can contribute to the Tunnelblick project:

  • Our biggest need is for people to test and report problems with Tunnelblick or suggest improvements.

  • We also need help translating Tunnelblick, especially for languages which are not yet completely translated (see Translation Status).

  • If you are an experienced Tunnelblick or OpenVPN user or a networking expert, you can help by answering questions in the Tunnelblick Discussion Group.

  • If you are have skills in programming or image creation and manipulation, you can help us develop Tunnelblick.

  • You can tell us how you use Tunnelblick.

Testing and Reporting Problems or Suggesting Improvements

Our goal is to make Tunnelblick bug free and easy to use, but we need help doing that. Any Tunnelblick user can help with this!

We prefer that you report problems and suggest improvements on the Tunnelblick Discussion Group, but you can use GitHub Issues or contact the developers directly if you consider it more appropriate. Please read this before you send in a problem report. Although it is primarily aimed at problems connecting a VPN, the diagnostic information it helps you gather is useful when investigating other problems, too.

Improving Translations

Tunnelblick is available in more than thirty languages but not all languages have complete translations. If you are familiar with one of our incompletely-translated languages we really need your help, but we also would love to get help verifying and improving our existing translations in all of our languages. See Localizing and Translating Tunnelblick for details.

Answering questions on the Tunnelblick Discussion Group

The developers try to answer questions raised on the Tunnelblick Discussion Group, but if you can answer a question, please do so and free us up to work on improving Tunnelblick.

Helping Develop Tunnelblick

If you are an experienced Mac application developer or network expert, or are experienced in image creation and manipulation, you can help us develop Tunnelblick. Contact the developers to offer your services.

Telling Us How You Use Tunnelblick
