Case Study

Hello! My name is John Leider and I am the founder of Vuetify, LLC.I started my company to help developers, especially design inept and inexperienced ones, build beautiful web applications.

Vuetify puts a large emphasis on its free aspect. Locking extra features or functionality behind a paywall just feels bad. Open Source is about sharing and improving code through community support.

5. GanttProject ($36K/year)

Dmitry Barashev (from Prague, Czechia) started GanttProject over 9 years ago.

$3K / month
1 founders / 0 employees

Case Study

My name is Dmitry Barashev and I am the guy who is working on GanttProject, a popular free open-source project scheduling application for desktop operating systems. GanttProject may be thought of as a replacement for Microsoft Project for those who can’t afford to spend $1000 on a Gantt chart drawing software. It is used by small and medium-sized businesses in construction, mechanical engineering, media production, and other industries, as well as at colleges on project management classes.

GanttProject is free for any purpose, however, there is an option to pay-what-you-want and, to my big surprise, quite a few people choose this option. This, along with a few ad banners, generates about $3000-5000 monthly. Quite far from the Forbes list, but not bad for a pet project.

$13.1M / month

Today, the non-profit has stayed true to its open-source roots and is the fifth most visited website in the world.
