NetBeans began in 1997 as Xelfi, a student project under the guidance of the Faculty of Mathematics and Physics at Charles University in Prague. A company was later formed around the project and produced commercial versions of the NetBeans IDE until it was bought by Sun Microsystems in 1999. Sun open-sourced the NetBeans IDE in June of the following year.
