"Creating easy to maintain and easy to consume API and event documentation that is always up to date has been one of the most consistent challenges of my career. EventCatalog has become the keystone tool to finally make it possible"
Adam Fanello, Strategic Cloud Software Architect, Rackspace Technology
Fair Use Policy
Our Starter plan is designed for small teams and startups. While there's no strict user limit, it's intended for:
- Teams documenting a single domain or small set of services
- Organizations with limited integration needs (0-1 integrations)
- Early-stage teams establishing documentation practices
We're proudly bootstrapped and focused on providing simple, transparent pricing — no per-user fees, no usage traps. Just tools that scale with your architecture, not your headcount.
If you're working across multiple teams or domains, adding multiple integrations, or scaling your event-driven architecture, we recommend our Scale plan for better scalability, federation capabilities, and included features.
