    658aug 2026

    Serious interview coding, memos and theme reports on your desktop, with serious desktop-software vibes.

    Windows installer/portable EXE or unsigned macOS DMG; Linux commonly runs the Python source or an Ubuntu release binary
    setup
    The first obstacle is platform packaging: Windows and macOS binaries are unsigned, while several Linux setups require Python source installation; VLC is also needed for audio/video coding

    CATMA

    open sourceGPL-3.0Local or hosted
    102jul 2026

    Collaborative text coding in a browser, built by academics and uninterested in your sales funnel.

    The catch vs Aurelius

    It is a serious collaborative text-annotation system, but it lacks Aurelius's researcher-friendly interview repository, rapid synthesis workflow, and product-research reporting.

    Use the free hosted web app, or run the CATMA Standalone Docker image with its bundled GitLab backend

    The hosted app is easy, but private/offline use means running a large Docker container with an embedded GitLab service and managing its volumes and updates
    your data
    The public service stores projects in CATMA's server-side GitLab repositories; standalone/self-hosted deployments keep CATMA and GitLab data in Docker volumes, with exports available as text, TEI-XML, CSV and Git repositories

    Taguette

    open sourceBSD-3-ClauseLocal or hosted
    88jan 2026

    Code interview excerpts and export themes without recreating an enterprise research repository.

    The catch vs Aurelius

    It handles highlights and themes well, but its text-focused scope lacks Aurelius's richer research repository, synthesis aids, and polished findings workflow.
