View Version Guide →Veetr was created by Jan Linhart, a principal software developer at Acquia who has been working on the open-source marketing automation platform Mautic, and before that on Joomla! CMS. Jan's decade-long commitment to open source stems from a deep belief that collaborative development creates better software for everyone.
The project has its roots in the heart of Europe, in beautiful Prague, Czech Republic. The name "Veetr" comes from the Czech word for wind—"vítr"—where the "í" is pronounced phonetically the same as "ee" in English, perfectly capturing the essence of this wind-monitoring sailing dashboard.
As an avid sailor, Jan spends his spring, summer, and autumn weekends at the Orlík Dam, one of the largest reservoirs in the Czech Republic. There, he competes in local regattas with friends and family aboard their Micro class sailboat—a popular small racing dinghy known for its exciting sailing characteristics and competitive one-design racing.
Like the wind that fills our sails, knowledge should flow freely. Every line of code, circuit diagram, and 3D model in Veetr is open source because Jan believes that's the future—a future where technology serves everyone, not just those who can afford proprietary solutions.
Whether you're a weekend racer at your local yacht club, a blue-water cruiser crossing oceans, or an electronics enthusiast who loves building things, Veetr welcomes you to join our growing community of sailing technologists.
