vsAmazon API Gateway vs WSO2 API Manager
API management head-to-head for ERP teams: evidenced capabilities, published pricing, and which ERPs each actually integrates with.
 Amazon API Gateway | ||
|---|---|---|
| Starting price | Pay-as-you-go, per API call plus data transfer | Open source (free, self-hosted) or usage-based subscription tiers (Basic, Pro, Enterprise) |
| Deployment | Cloud | Cloud, On-premise, Hybrid |
| Company size | — | Mid-market, Enterprise |
| Stated ERP integrations | SAP | None listed |
| Vendor | Amazon Web Services, Inc. | WSO2 |
Our take
Where Amazon API Gateway leads
- Stronger evidenced coverage on 12 of the 27 capabilities where they differ (led by custom / serverless authorizers and api key issuance & validation).
- Stated SAP integration the alternative doesn't list.
Where WSO2 API Manager leads
- Stronger evidenced coverage on 15 of the 27 capabilities where they differ (led by self-service developer portal and api catalog & discovery).
Where they differ
The 27 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.
