Deep Dive: Switching from Aurelius to CATMA
Trade-offs, installation & data architecture
What you trade away
It is a serious collaborative text-annotation system, but it lacks Aurelius's researcher-friendly interview repository, rapid synthesis workflow, and product-research reporting.
How to deploy CATMA
Use the free hosted web app, or run the CATMA Standalone Docker image with its bundled GitLab backend
What it takes to run
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
Where your data lives
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
Why fork CATMA instead of vibe-coding a Aurelius clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Aurelius, organize interview notes, code excerpts, and synthesize themes into findings. The hard boundary is research-specific tagging, collaboration, reporting, and import workflows, plus participant network, synthesis workflow, and collaboration.
