The open-source operating system for animal health.
The Yosemite Crew PIMS - the unified dashboard a veterinary practice runs on.
Yosemite Crew is a free, fully customizable Practice Management System (PMS) for veterinary care, bringing pet owners, veterinary clinics, and developers into one ecosystem. It is a product of DuneXploration UG (haftungsbeschränkt) and aligns with SOC 2 (Type I report available), ISO 27001:2022, and GDPR.
This wiki is the structured knowledge base for building, extending, and operating Yosemite Crew: architecture, per-subsystem walkthroughs, the decisions behind the code (ADRs), every active design plan, and the roadmap. It complements — and does not replace — the canonical sources:
- Code and canonical docs live in the main repository. Where a wiki page and the repo disagree, the repo wins.
- DeepWiki is an auto-generated, ask-anything companion indexed from the code — use it for code-level Q&A; use this wiki for curated, decision-level and cross-cutting context.
