QualCoder is free, open source software for qualitative data analysis. You can code text, images, audio and video, write journal notes and memos. Categorise codes in a tree-like hierarchical categorisation scheme. Coding for audio and video requires the VLC media player. VLC must be installed for QualCoder to work with audio and video data. Coder comparison reports can be generated for text coding. A graph displaying codes and categories can be generated to visualise the coding hierarchy. Most reports can be exported at html, open document text (ODT) or as plain text files.

  • Limited Documentation
    While the software is actively developed, users might find the available documentation and resources insufficient for troubleshooting complex issues.
  • Performance Issues
    Handling large datasets can lead to performance slowdowns, which might impact the overall efficiency of the analysis process.
  • No Commercial Support
    Being a free and open-source project, it lacks the dedicated customer support that commercial tools might offer, which can be a challenge for some users.
  • Compatibility with Other Tools
    Integration with other software might be limited compared to proprietary qualitative analysis tools that offer built-in compatibility with a wider range of platforms.

5 Ultimate Python Libraries for Image Processing
Pillow is an image processing library for Python derived from the PIL or the Python Imaging Library. Although it is not as powerful and fast as openCV it can be used for simple image manipulation works like cropping, resizing, rotating and greyscaling the image. Another benefit is that it can be used without NumPy and Matplotlib.

QualCoder Reviews

  1. Leon van der Neut
    Effective no non-sense software

    I used Qualcoder to code 100 hours of public hearings transcripts and I found it a very pleasant experience. The workflow is intuitive and quick. Even though some transcripts went over 150.000 characters, I was using about 50 codes, and have transcripts with over 100 different coded segments, the program remained stable. Using the | character in the search field allows for the use of multiple keywords at once, which was very effective. The report function allows you to produce overviews of interview segments per code and various kinds of statistical analysis, which can be integrated with R-Studio. Many thanks to Dr. Colin Curtain for the development and software support.

    ๐Ÿ‘ Pros:    Active community|Completely free and open source|Very stable|Intuitive workflow|Integration with r-studio
    ๐Ÿ‘Ž Cons:    .pdf coding requires turning pages in file
  2. The best open source alternative to paid CAQDAS

    QualCoder is one of the best CAQDAS I have used not just because it is free and open source but also because of the functionalities and constant improvements.

    ๐Ÿ Competitors: ATLAS.ti, NVivo
    ๐Ÿ‘ Pros:    Developer is responsive to feedback/requests and makes improvements|Easy to use|Advanced features
  3. Really good alternative to paid CAQDAS

    I really like using QualCoder 3.0 for its ease of use and intuitive interface.

    ๐Ÿ‘ Pros:    Easy to use|Intuitive|Easy merge of projects
    ๐Ÿ‘Ž Cons:    Only two hierarchies allowed for codes
