arc42 is an open-source template for documenting and communicating software architecture, structured into twelve well-defined sections. It is technology- and process-agnostic, available in multiple formats (AsciiDoc, Markdown, Word) and 12 languages.
Use cases
- document software architecture
- structure architecture documentation for a team
- communicate system design to stakeholders
- create architecture docs in AsciiDoc or Markdown
- prepare for iSAQB architecture certification
- standardize architecture documentation across projects
When to choose
- you need a proven, pragmatic structure for architecture documentation
- your team wants low-effort docs that stay up to date
- you want a technology- and process-agnostic template usable in agile or formal settings
When to avoid
- you need tooling that auto-generates documentation from code
- you require a strict formal notation like UML-only documentation
- your organization mandates a different documentation standard such as C4 or ISO 42010 templates
