875-node technology tree from primitives to advanced manufacturing. Modular knowledge packs for community development and resilience education.
rkOS (powered by ARK) maps the complete technology tree and provides optimal pathways for learning and building — whether you're bootstrapping a makerspace, teaching resilience education, running community workshops, or developing self-sufficiency skills.
While rk.app focuses on emergency response for individuals, rkOS is the foundational knowledge system for communities, educators, and builders.

rkOS grows through community contribution. Field-test procedures, validate tech nodes, adapt knowledge to your bioregion.
Write detailed implementation procedures for tech nodes. Share field-tested knowledge with the community. All contributions are reviewed and validated.
Test theoretical nodes in practice. Document what works, what doesn't, and context-specific adaptations. Help move nodes from theoretical to validated.
Adapt procedures for local contexts. Share resource substitutions, seasonal constraints, and cultural considerations for your bioregion.
Help make rkOS accessible globally. Translate procedures, tech tree documentation, and knowledge packs into other languages.
Teach optimal pathfinding through the tech tree. Understand dependencies and efficient development paths.
Plan tool acquisition and capability development. Navigate the manufacturing tree efficiently.
Study technological development paths. Understand why certain tech emerged when it did.
Plan self-sufficiency progression. Understand resource dependencies and seasonal constraints.
Create realistic post-collapse scenarios. Understand what's actually possible with limited resources.
Analyze technological dependencies. Plan resilient infrastructure with redundancy.
From primitive tools to semiconductors. Offline and complete.
