The Real Price of 'Free': Why Open-Source IDPs Cost Millions

While Backstage carries no license fee, operating it requires 2-3 full-time senior engineers annually—a hidden cost of $300,000-$450,000 before custom development begins. For a 200-developer organization, three-year deployment costs exceed $1.5 million, often exceeding commercial alternatives like Port and Cortex. This analysis reshapes how engineering leaders evaluate platform tooling: licensing fees represent only a fraction of true total cost of ownership.
