Application Programming Interfaces (APIs) are fundamental to the modern digital economy, acting as vital connections that drive enterprise innovation, enable smooth integration, and enhance customer experiences. However, traditional API management often falls short in scalability, governance, and security, hindering comprehensive digital transformation. Therefore, choosing an API management platform is a strategic decision for enterprises undergoing modernization, with long-term implications for performance, compliance, and cost-efficiency. This paper addresses this crucial need by providing a thorough comparative analysis of ten leading API management platforms: Google Apigee X, MuleSoft API Management, Boomi API Management, SAP BTP API Management, Oracle API Management, IBM API Connect, Axway Amplify, Kong Konnect, Microsoft Azure API Management, and Amazon API Gateway. Our evaluation framework rigorously assesses key areas such as deployment flexibility, security and governance, developer experience, advanced analytics, lifecycle management, and total cost of ownership. The analysis reveals significant differences among the offerings, highlighting a clear contrast between cloud-native, ecosystem-dependent solutions from hyperscale providers and independent, multi-cloud platforms designed for hybrid deployments, sophisticated governance, and monetization strategies. This study synthesizes information from extensive vendor documentation, current analyst reports, and market data to offer practical, evidence-based guidance to enterprise architects and technology leaders, helping them select an API management solution that precisely aligns with their strategic modernization goals.
