Texmaker is a free and open-source LaTeX editor with an integrated PDF viewer compatible with Linux, macOS, and Windows.

Written entirely as a Qt app, it features many tools needed to develop documents with LaTeX.

The editor includes full Unicode support, inline spell checking, auto-completion, code folding and rectangular block selection.

Texmaker includes wizards for the following tasks: Some of the LaTeX tags and mathematical symbols can be inserted in one click and users can define an unlimited number of snippets with keyboard triggers.

Texmaker automatically locates errors and warnings detected in the log file after a compilation.
