Weft QDA – a free, open-source tool for qualitative data analysis Using Weft QDA Getting started and getting help History and Future Thanks A few QDA Links Weft QDA – the development of a rudimentary CAQDAS appplication

Weft QDA

Weft QDA is (or was) an easy-to-use, free and open-source tool for the analysis of textual data such as interview transcripts, fieldnotes and other documents. An excerpt from my MSc dissertation explains the thinking behind the software in more detail.

The software isn’t being maintained or updated, but the most recent version is available for interest. This version includes some standard CAQDAS features: (Follow the links to see screenshots)

  • Import plain-text documents from text files or PDF
  • Character-level coding using categories organised in a tree structure
  • Retrieval of coded text and ‘coding-on’
  • Simple coding statistics
  • Fast free-text search
  • Combine coding and searches using boolean queries AND, OR, AND NOT
  • ‘Code Review ’ to evaluate coding patterns across multiple documents
  • Export to HTML and CSV formats

Using Weft QDA

The currrent version is 1.0.1. which was released in April 2006. IMPORTANT. this software is offered without any warranty or support. Some people may still find it interesting or even useful, but:

  • it is not for major projects like a PhD thesis.
  • Version 1.0.1 does contain bugs that can occasion the loss of data in your analysis, or make the project file unreadable, so
  • If you use Weft QDA in earnest, you should regularly make a back-up of your project (the .qdp file).
  • (Jun 2014) Since Weft QDA was developed, free (but not open source) versions of some commercial software have emerged (e.g. QDA Miner Lite ).

For Windows

Weft QDA 1.0.1 was developed for Windows XP, but may work on newer versions. Windows users should download this installer which contains everything you need to use Weft. It’s available to download via Softpedia’s Weft QDA page .

Save the installer somewhere on your hard disk, then double-click the saved icon to run the installer. Follow the on-screen instructions.

Using 1.0.1 on Linux

Unfortunately, Weft QDA 1.0.1 depends on such old versions of system libraries (e.g. GTK) that it is very difficult or impossible to run Weft QDA 1.0.1 on a modern Linux distro. The source was hosted on RubyForge, but the site no longer exists. There is historic information on installation options and prerequisites .

The best way to run Weft QDA on Linux is to use WINE. C Lejeune offers further information on Weft QDA on (Debian) Linux .

Getting started and getting help

The Weft QDA Manual is the best place to start learning how to use the software. This manual is also available as a PDF for printing or on-screen viewing. Documentation in a variety of formats is included in the downloadable packages for off-line browsing.

There is also a spanish translation of the manual. courtesy of M. Cecilia Martínez.

Getting Help

I’m afraid there is no support for using Weft QDA; the mailing list previously on Rubyforge is no longer operational. Please don’t email me directly with requests for help using Weft QDA; I’m afraid I won’t reply.

History and Future

Weft QDA was originally written out of curiosity whilst completing a Masters in Social Research Methods at the University of Surrey in 2004. I was annoyed by over-priced and over-complex commercial CAQDAS. The software was tidied up and documented, and then first released in 2005.

Development / Abandonment

I did a lot of work towards a version 2.0 of Weft QDA, and got as far as a basic alpha release. Version 2.0 was going to add support for multilingual text, photos, audio and video documents, along with other new features and interface improvements, and was going to work well on OS X and modern Linux distros. However, I haven’t done any serious development on Weft QDA since early 2009, and it’s unlikely I’ll resume at any time soon. I’m just interested in thinking about and doing other things at the moment.

The project has thus been orphaned for several years. If you have a serious interest in reviving it, I do still have the source code somewhere. Weft QDA was written in the Ruby programming language, using WxRuby for the user interface and SQLite for the file storage.


Thank you to those who’ve tried the application, and especially to all those who’ve tried it and responded with their suggestions, views and kind words of thanks. Thanks to Rubyforge, who did for a long time hosted the project, including providing the downloads. Thanks also to the other open-source projects upon which it depended.
