Fair usage policy
Our Approach to Fair Pricing🔒 What is the Fair Use Policy?
EventCatalog is an open source project built to be a self-hosted, transparent, and developer-first tool — clear plan limits, no unexpected overages, no vendor lock-in. To keep things simple, sustainable, and fair for everyone, we apply a fair use policy to some of our pricing tiers.
💡 Why Fair Use?
Rather than enforce strict technical limits, we trust teams to choose the plan that best reflects the scale and value they're getting from EventCatalog. We use team size, company stage, and governance needs as guidelines to help determine which tier is appropriate.
- ✅ Keep EventCatalog simple to deploy and operate
- ✅ Avoid turning every catalog reader into a billable seat
- ✅ Ensure small teams can access powerful tooling affordably
- ✅ Encourage larger companies to contribute fairly to our sustainability
👥 What counts as a catalog user?
A catalog user is someone who regularly accesses your EventCatalog instance to read, create, manage, or collaborate on documentation.
Editor seats are different. They are for the people who maintain catalog content with EventCatalog Editor.
We define fair use based on typical team sizes:
- Starter: Up to 20 catalog users, under €1M ARR
- Scale: Up to 50 catalog users, under €5M ARR
- Enterprise: 50+ catalog users, regulated environments, or advanced needs
🤝 What if we grow beyond our plan?
That's a good thing! 🎉 If your usage consistently exceeds the fair use limits of your plan, we'll reach out to discuss an appropriate upgrade. We won't cut you off or block features — we just ask that you help support the project in proportion to the value you're getting.
