## 🎯 Why EventCatalog?
**vs. Generic Documentation Tools**
- ✅ Purpose-built for distributed systems and event-driven architectures
- ✅ AI-powered discovery and semantic search
- ✅ Schema governance with breaking change detection
**vs. Vendor-Specific Tools**
- ✅ Platform-agnostic (works with any broker/platform)
- ✅ Vendor-neutral (avoid lock-in)
- ✅ Open source with commercial support
**vs. Service Catalogs**
- ✅ 5 minutes to value vs 6+ months implementation
- ✅ Event-driven architecture depth, not generic breadth
- ✅ Runtime discovery from traffic analysis
