What makes it different
Designed for SaaS that pivots—modular architecture with stable contracts so changing pricing, billing providers, or infrastructure requires config changes, not rewrites
One-time purchase with lifetime usage rights; you own the code forever with no runtime licensing checks
Built by founder with 15 years of SaaS experience, including Billing Tech Lead at Loom through Atlassian acquisition
Powers the website you're reading—not a packaged side project; every abstraction earned its place the hard way
Guarantees instead of conventions: runtime enforcement prevents data leaks and permission errors by design, not developer discipline
Domain engines own invariants, not vocabulary: reusable logic without tight coupling to specific business requirements
Self-hostable vertical on pure SQLite with no platform dependency
