IBM API Connect vs WSO2 API Manager
API management head-to-head for ERP teams: evidenced capabilities, published pricing, and which ERPs each actually integrates with.
| Starting price | Tiered SaaS subscription plus custom on-premises and hybrid licensing | Open source (free, self-hosted) or usage-based subscription tiers (Basic, Pro, Enterprise) |
| Deployment | Cloud, On-premise, Hybrid | Cloud, On-premise, Hybrid |
| Company size | — | Mid-market, Enterprise |

| Vendor | IBM | WSO2 |
Our take
Where IBM API Connect leads
- Stronger evidenced coverage on 9 of the 23 capabilities where they differ (led by app registration & subscriptions and request/response transformation).
Where WSO2 API Manager leads
- Stronger evidenced coverage on 14 of the 23 capabilities where they differ (led by ai token quotas & cost attribution and semantic caching for ai requests).
Where they differ
The 23 capabilities (of 47 in the API management taxonomy) where the evidence separates them, biggest gaps first. “Not evidenced” means our research found no public documentation of this capability — the vendor may still offer it. Confirm on a demo.
