Bringing Domain-Driven Design into your codebase.

Open source tools that make DDD architecture visible, versionable, and maintainable — right where your code lives.

Architecture documentation goes stale. Bounded context diagrams live in wikis nobody updates. Teams lose track of who owns what.

DomainLang solves this with a domain-specific language for DDD that treats architecture models as first-class citizens in your repository — reviewable in pull requests, validated by your IDE, and always in sync with reality.

• Developer experience — IDE support with syntax highlighting, completion, and validation
• Living documentation — Architecture that evolves with your codebase
• Automation-ready — Queryable models for consistency checks and artifact generation

This project is built in the open and welcomes contributors at all levels.

Built on the belief that architecture decisions deserve the same rigor as code.
