## Why Cronozen?
You shouldn't have to build multi-tenancy, auth, billing, and audit trails from scratch every time.
Row-level data isolation across 200+ tables. Scoped database queries. Center-based access control. Works from day one.
SHA-256 hash chains seal every decision. Tamper-evident, audit-ready, exportable as JSON-LD. No other SaaS platform has this.
Custom domains, branding, landing pages via CloudFlare Workers. Your customer sees their brand — powered by your infrastructure.
Workflow engine, pgvector embeddings, 5-level governance guards. AI decisions are recorded, reviewed, and provable.
How Cronozen differs from traditional SaaS stacks and why it matters for regulated industries.
