Open Source
Our contribution to the developer community
Arness -- our open-source toolkit for Claude Code -- takes projects from business idea through validated prototype to production deployment. The engineering practices refined across years of production delivery, MIT-licensed.
Not a side project. A public expression of how we think about building software: structured, auditable, repeatable. Released because the community deserves better tools.
Capabilities
- SPK Product discovery, stress testing, prototyping, and visual design
- COD Feature spec, implementation planning, execution, and code review
- INF Infrastructure audit, containerisation, CI/CD, and deployment
- ART Durable Markdown artifacts — traceable from idea to merged PR
- INT Zero-config setup — learns your stack, role, and conventions once
- MIT MIT-licensed, open for inspection, no vendor lock-in
