Magic Quadrant for API Management
How does Gartner define the API Management market in 2025?
Gartner defines the application programming interface (API) management market as the market for software to manage, govern and secure APIs. APIs modernize IT architectures. They provide context, tools and resources to generative and agentic AI programs and provide access to systems, services, partners and data services. API management tools enable organizations to plan, deploy, secure, operate, version control and retire APIs, regardless of their size, region or industry.

What product features are required to be included in this year's evaluation?
- API portal: Provides a self-service interface for API consumers to discover and try APIs. An API catalog is necessary for the registration of APIs.
- API gateway: Provides, or integrates with, gateways for runtime management, security, policy enforcement, throttling, operational control and usage monitoring for APIs.
- Policy management: Provides style enforcement, API mediation, usage limits, throttling and security configurations.
- Governance: Manages API versions, access control, publication and operation.
What are the common features of top products in the API Management space?
- API design: These capabilities deliver a meaningful developer experience and tools to design APIs and enable API usage for existing systems.
- API testing: Provides a range of testing capabilities, from basic mock testing to advanced functional, performance and security testing of APIs.
- Monitoring and analytics: Ability to produce, collect and report operational metrics and meaningful statistics for API consumption.
- Security: Ability to protect APIs from malicious activity and integrate with existing security infrastructure; enforce identity and access management rules; enforce design time and operational security.
- AI gateway support: Provide security, mediation and traffic management for AI access to enterprise data and resources.
- AI protocol support: Support implementations of emerging protocols like the Model Context Protocol (MCP) and Agent2Agent (A2A).
- AI-enabled productivity: Aimed at improving developer experience, productivity and operational rigor (when generating API specifications, documenting APIs, obtaining usage analytics or optimizing traffic, for example).
- Gateway federation: The ability to manage multiple instances and form factors of gateways, including third-party API gateways.
- API mediation: Features to implement composite services, service mediation, and protocol mapping and translation.
- Service mesh: Ability to integrate with or mediate traffic to and from service mesh solutions.
- Monetization: The ability to implement pricing models, billing strategies, chargeback methods as well as to commercialize and market API products.
Scope Exclusions
- Products specific to one industry only
- Products limited to adjacent markets (such as iPaaS or application security)
- Vendors with less than $50 million revenue from API management ($6 million for open-source vendors)

FAQs
Q: What does this research cover?
A: This research evaluates 17 vendors in the API management market, assessing their ability to execute and completeness of vision. It covers vendors offering software to manage, govern and secure APIs, with mandatory features including API portal, API gateway, policy management, and governance. The research analyzes vendors' capabilities across mandatory and common features including API design, testing, monitoring, security, AI gateway support, gateway federation, service mesh, and monetization.
Q: Who should use this research?
A: Software engineering leaders should use this research to identify their organization's API management use cases, evaluate technical and sourcing requirements, and find the right vendors to shortlist. The research is particularly valuable for organizations looking to: develop AI capabilities and improve productivity through agentic AI; build foundational capabilities addressing legacy and modernization initiatives; advance digital strategies and commercialize APIs; build modern cloud-native architectures; and level up API governance and security across diverse multicloud, multivendor environments.
Q: What are the mandatory features of vendors included in this market?
A: To be included in this Magic Quadrant, vendors must provide: (1) API portal - a self-service interface for API consumers to discover and try APIs with an API catalog for registration; (2) API gateway - provides or integrates with gateways for runtime management, security, policy enforcement, throttling, operational control and usage monitoring; (3) Policy management - provides style enforcement, API mediation, usage limits, throttling and security configurations; and (4) Governance - manages API versions, access control, publication and operation.
Q: What are some reasons for not being included in this report?
A:
- Offering not generally available as of June 2024
- Offering specific to one industry or limited to adjacent market only
- Revenue below threshold ($50M for commercial, $6M for open-source)
- More than 90% of revenue from single geographic region
- Fewer than 150 paying customers
- Does not provide all mandatory features (API portal, API gateway, policy management, governance)
Q: What differentiates Ability to Execute vs. Completeness of Vision?
A: Ability to Execute evaluates how well vendors currently deliver their API management solutions, focusing on product capabilities, sales performance, customer experience, operational excellence, and market responsiveness. It measures execution in the present state with emphasis on product/service quality (High weighting) and various medium-weighted operational factors. Completeness of Vision assesses vendors' strategic direction and future potential, evaluating their understanding of market trends, product strategy, innovation capabilities, and business approach. It emphasizes strategic elements like Market Understanding, Product Strategy, and Innovation (all High weighting) while considering how vendors plan to address future API management needs including AI, agentic architectures, and evolving security requirements. Essentially, Ability to Execute is about 'doing' while Completeness of Vision is about 'planning and innovating' for the future.
