This page contains information about the most recent builds (development and stable branches) of the Alpha Text Editor.

Alpha is a multi-modal, programmable text editor that has become famous especially for its extraordinary capabilities for editing TeX and LaTeX documents, Web pages in HTML, or source files for many programming languages.

Take a quick guided tour by visiting the Screenshots Gallery to get an idea of what Alpha can do.

The stable releases are usually announced on the Alpha-devel list (you can subscribe here ).


All the development effort is now dedicated to the AlphaCocoa project which is a rewrite from scratch of Alpha. It is written in Objective C and based on the Mac OS X Cocoa framework. This is an Open Source project hosted on SourceForge.

It is now fully functional and reliable.

Releases are available in the Download Area of the project at SourceForge.

Older versions

AlphaX is the previous version of Alpha which used to run on Mac Classic (pre OS X) and later on Mac OS X (10.4 or greater). AlphaX is now retiring. It was based on the now deprecated Carbon framework and there is no guarantee that it runs on the latest versions of OS X. It is not maintained any longer but is kept available to people still running on systems older than 10.9 (aka Mavericks).

The last official release of AlphaX was version 8.2.3. Download the disk image here:

AlphaX-8.2.3.dmg (16.8M)

Once it is downloaded, double-click on the icon of the disk image. A window containing the application will open. Then drag the AlphaX application to the Applications folder (or anywhere you like on your machine).

Under Mac OS X 10.9 (Mavericks), you need at least version 8.2.2 of AlphaX.


You may see the following message when launching this new version for the first time under Mavericks : "AlphaX can't be opened because it is from an unidentified developer". This is due to the fact that AlphaX is not (yet) a signed application. Here are instructions to bypass the Security & Privacy System preference which is responsible for this message: how-to-open-applications-from-unidentified-developers (instructions are given for Mountain Lion but they apply just the same to Mavericks).


Here is a compiled binary of the Tclapplescript extension version 2.1 which can be used in AlphaX on Yosemite systems (Mac OS X 10.10). Download and unzip the archive, then copy it inside the AlphaX application bundle in

This fixes the issue reported with the version 1.0 where loading the extension resulted in an error message "Error: Error opening component".
