We'll help you roll it out across your organization
One flat price. Your whole organization.
Most developer portals charge per seat, so the bill grows every time another engineer reads your docs. EventCatalog doesn't. Here's what that means as your team grows:
| Team size | Per-seat developer portals | EventCatalog Scale |
|---|---|---|
| 25 engineers | $625–$1,000/month | $449/month |
| 50 engineers | $1,250–$2,000/month | $449/month |
| 100 engineers | $2,500–$4,000/month | $449/month |
Per-seat range based on published and reported list prices ($25–$40 per developer/month) for popular developer portals, July 2026.
Thinking about self-hosting Backstage instead? "Free" typically costs 3+ full-time engineers to build and maintain — around $450K/year in engineering time before your architecture is documented. EventCatalog is maintained for you: Scale is under $15 a day, and Enterprise includes onboarding, training, and support. Already on Backstage? EventCatalog integrates with it.
