TeXstudio is a cross-platform open-source LaTeX editor. Its features include an interactive spelling checker, code folding, and syntax highlighting. It does not provide LaTeX itself—the user must choose a TeX distribution and install it first.

Originally called TexMakerX, TeXstudio was started as a fork of Texmaker that tried to extend it with additional features while keeping its look and feel.

TeXstudio was forked from TeXMaker in 2008 as TeXMakerX.^[3] Changes in the fork were mainly in the editing area with code folding, syntax highlight, text selection by column, and multiple text selections.^[4] The project was initially named TeXmakerX, starting off as a small set of extensions to TeXmaker with a possibility that the additions could be merged back into the original project.

The first release of TexMakerX was released in February 2009 on SourceForge.^[5] Collaborating on the SourceForge community web site reflected a preference different from the original TeXMaker development community, who maintain an independent hosting site.^[6]

In August 2010, concerns were raised about potential confusion between the newer TeXMakerX project on SourceForge, and the older TeXMaker project at xm1math.net.^[7] In June 2011, the project was renamed as TeXstudio.^[8]

The TeXstudio community acknowledges that "TeXstudio originates from Texmaker", but "significant changes in features and the code base have made it to a fully independent program".^[9]
