Based on 2026 G2 verified review data across 2,500+ products.* API management software allows users to monitor, control, and monetize their application programming interfaces (APIs) in a secure development environment. These tools help administrators monitor connection consistency, traffic, errors, and security for their team’s published APIs. A company’s IT department uses this tool during the post-production phase of an API’s lifecycle, taking over from developers after successful [API design](https://www.g2.com/categories/api-design). From there, essentially all maintenance, monitoring, and management related to the API occurs within the API management product, including versioning, deprecation, and policy enforcement. Some [API marketplace](https://www.g2.com/categories/api-marketplace?source=search) solutions contain tools for managing APIs, but those tools are less focused on managing an API and are more focused on choosing external APIs to benefit an actual product. To qualify for inclusion in the API Management category, a product must: - Provide security, traffic, and functionality monitoring - Equip teams with operations and monetization tools ## Top API Management Tools at a Glance | # | Product | Rating | Best For | What Users Say | |---|---------|--------|----------|----------------| | 1 | [Postman](https://www.g2.com/products/postman/reviews) | 4.6/5.0 (1,748 reviews) | Multi-environment API lifecycle testing and collaboration | "[The easiest way I've found to work with APIs](https://www.g2.com/survey_responses/postman-review-13046207)" | | 2 | [Celigo](https://www.g2.com/products/celigo/reviews) | 4.6/5.0 (1,026 reviews) | NetSuite-anchored API and EDI flow automation | "[Seamless Integration with Exceptional Support](https://www.g2.com/survey_responses/celigo-review-1996577)" | | 3 | [MuleSoft Anypoint Platform](https://www.g2.com/products/mulesoft-anypoint-platform/reviews) | 4.5/5.0 (655 reviews) | API-led connectivity with reusable integration layers | "[Powerful DataWeave, Rich Connectors, and Strong API Governance with MuleSoft](https://www.g2.com/survey_responses/mulesoft-anypoint-platform-review-12850876)" | | 4 | [Workato](https://www.g2.com/products/workato/reviews) | 4.7/5.0 (748 reviews) | Low-code API orchestration across enterprise app ecosystems | "[Workato helps us building complex integrations at lightning speed.](https://www.g2.com/survey_responses/workato-review-10305521)" | | 5 | [Kong Konnect](https://www.g2.com/products/kong-inc-kong-konnect/reviews) | 4.4/5.0 (320 reviews) | Plugin-driven API gateway for microservices governance | "[From Product Creation to Future Market Dominance](https://www.g2.com/survey_responses/kong-konnect-review-9756107)" | | 6 | [Apidog](https://www.g2.com/products/apidog/reviews) | 4.8/5.0 (217 reviews) | Unified API design, testing, and documentation | "[All-in-One API Workflow That Saves Time and Keeps Everything in Sync](https://www.g2.com/survey_responses/apidog-review-12702549)" | | 7 | [Amazon API Gateway](https://www.g2.com/products/amazon-api-gateway/reviews) | 4.2/5.0 (128 reviews) | AWS-native serverless API routing and authorization | "[Fast, Secure Serverless APIs with Amazon API Gateway and AWS Integrations](https://www.g2.com/survey_responses/amazon-api-gateway-review-12933939)" | | 8 | [Apigee Edge](https://www.g2.com/products/apigee-edge/reviews) | 4.4/5.0 (23 reviews) | Policy-driven API proxy lifecycle and monetization | "[Enterprise-Ready API Management That Scales with Apigee Edge](https://www.g2.com/survey_responses/apigee-edge-review-12585252)" | | 9 | [Boomi](https://www.g2.com/products/boomi/reviews) | 4.4/5.0 (455 reviews) | Low-code API lifecycle and cross-system integration | "[Boomi’s Powerful Integrations and AI Automation Save Us Time and Effort](https://www.g2.com/survey_responses/boomi-review-12901875)" | | 10 | [SAP Integration Suite](https://www.g2.com/products/sap-integration-suite/reviews) | 4.3/5.0 (262 reviews) | SAP-native API governance and cross-system integration | "[Efficient SAP Ecosystem Connectivity with Outstanding API Management](https://www.g2.com/survey_responses/sap-integration-suite-review-12616504)" | ## G2 Grid® for API Management Tools ![G2 Grid® for API Management Tools plotting products by satisfaction and market presence](https://www.g2.com/categories/api-management/grids.png?focus%5B%5D=20238&focus%5B%5D=23331&focus%5B%5D=4208&focus%5B%5D=15884&focus%5B%5D=17294&focus%5B%5D=1316415&focus%5B%5D=20160&focus%5B%5D=13694) Highlighted products: Postman, Celigo, MuleSoft Anypoint Platform, Workato, Kong Konnect, Apidog, Amazon API Gateway, and Apigee Edge.

[Development Software](https://www.g2.com/categories/development) ## What Software Categories Are Similar to API Management Tools? - [iPaaS Software](https://www.g2.com/categories/ipaas) - [API Development Tools](https://www.g2.com/categories/api-development) - [API Platforms](https://www.g2.com/categories/api-platforms) --- ## How Do You Choose the Right API Management Tools? ### What You Should Know About API Management Software ### What are API management tools? [Application programming interfaces, or APIs](https://www.g2.com/articles/what-is-an-api), are sets of communication protocols, subroutines, and other tools that help programmers develop and integrate software. APIs can allow web services, applications, libraries, operating systems, and more to perform certain functions through abstraction, especially those concerned with communication and integration with other systems. This allows programmers to add further functionalities when building applications through the use of APIs without the need to understand the full extent of operations going on behind the scenes of a function. For example, developers can pull data from a communication API to integrate text or voice communication functionality in their applications. APIs are often used to successfully build microservices or collections of individual services that make up an application. Developers can arrange loosely connected microservices instead of building monolithic programs to create more efficient and lightweight applications. This creates an application structure by which each microservice needs only to store data if that data is relevant to its exact function. Then, it can pass off that data to another microservice within the application or pull data from another microservice using APIs. Of course, many companies and development teams build APIs for external developers. Upon publishing, these APIs can then be monetized and analyzed to benefit the API provider. API management platforms enable companies to maximize the value of their published APIs.  API management software picks up after API design software, which allows users to handle the preproduction and development of APIs on the backend, to enable developers to monitor, control, and monetize their APIs once they are created and published. In the same functional vein as other management solutions, API management platforms allow users to control which of their APIs are accessible, permit edits to APIs when they are needed, assess user analytics, and more. These software tools also provide an API gateway that handles any incoming API calls from users and returns relevant results to those users. In conjunction with API design software, API management solutions go beyond backend control to allow users to maintain full lifecycle API management. ### What are the common features of API management platforms? The following are some core features within API management software that can help users: **API editing:** API management platforms let developers oversee live APIs, give them editing tools when small changes need to be made, and provide the ability to delete any no longer needed APIs. This gives teams complete lifecycle API management and helps keep company strategies in sync by ensuring that current focuses are reflected by relevant APIs, uncluttered by redundancies or outdated interfaces. In many cases, user feedback and usage analytics are crucial for getting an API to the best possible state, meaning post-publishing editing capabilities are vital. **API monitoring:** API management tools constantly monitor a provider’s APIs, tracking metrics such as performance, functionality, user accessibility, traffic, and signs of security threats. For example, the software will monitor an API’s response time when called to perform a function, comparing it against benchmarks set by the API provider. The software monitors this response time as a constant average over time based on the many calls that can occur. Often, correlations between performance slips and possible causes, such as increased traffic, can be monitored to provide teams with the most relevant information regarding their APIs’ status.  **Data transformation:** Many API management platforms include functionality for translating complex datasets and backend systems into formats that applications can interpret. This ensures that clients’ API calls can be completed successfully and that the data they seek is returned to them in a useful state. With API management platforms handling this translation, the burden is shifted off developers’ shoulders when building each API. Developers don’t have to include scripting to handle this data translation, as they can get their APIs up and running more efficiently. **Documentation:** API management solutions allow teams to create documentation around their APIs, including action items, issue logs, etc. These software tools’ documentation functions work with monitoring tools to ensure that everyone understands what’s going on with their APIs. For example, if a published API dips below performance benchmarks, relevant team members will see that reflected in documentation and can take steps to remediate the issue. This keeps development teams informed and allows for quick turnarounds when potentially costly problems arise.  **Reporting and analytics:** API management tools offer reporting and analytics around each API’s usage. This helps developers see how their APIs are being used and with what frequency. API management software grants companies finer control over the value and data streams their published APIs generate. User analytics such as API traffic provide essential data that can help inform future product decisions, for example, and API management solutions give companies a toolset to perform comprehensive analysis. Via dashboards and custom metrics, development teams can keep tabs on API usage and even explore the demographic trends behind API calls.  **Automation:** API management platforms automate many processes and tasks necessary for effective and efficient API management. Monitoring, for example, occurs constantly and automatically to provide teams with real-time updates whenever an issue arises or other relevant information becomes available. Sometimes, teams can even set custom alert events based on certain API activities. API management tools can also automatically produce actionable documentation around API activity, such as traffic trends and errors, giving developers a starting point to act on new information or remediate problems. The automated functionality of API management software gives development teams peace of mind while freeing them to focus on other tasks. **Traffic control:** Many API management products go beyond traffic monitoring to grant teams full traffic control. This gives companies the tools necessary to keep their APIs more secure. For example, API management platforms can monitor for abnormal traffic spikes and then limit access to prevent overloads like [DDoS attacks](https://www.g2.com/articles/ddos-attack). This software also allows administrators to control API access to keep out suspicious visitors—this level of control grants API providers security and proactive tools to maintain smooth operations.  ### What are the benefits of API management software? **Convenience:** API management tools save users time and effort by simplifying and automating processes like monitoring, analytics, documentation, and more. These solutions bring a development team’s published APIs under one dashboard, allowing them to drill down, manage, and edit APIs as needed. Automation frees development teams to focus on other tasks without being bogged down in near-constant upkeep, relying instead on the monitoring and alerting capabilities provided by the software.  **Transparency:** These solutions allow users to monitor every aspect of their APIs. Between reports and analytics, documentation, and tagging, team members are aware of exactly what’s happening with their APIs at all times. Via dashboards, development teams gain a holistic view of the statuses, traffic, trends, and issues related to their APIs. Teams can then collaborate on action items using clear, consistent documentation tools. **Comprehensive management:** The automation, monitoring, and documentation functionalities employed by API management platforms add up to a comprehensive management strategy that can be quite difficult to replicate without this software. API managers help by constantly parsing API data to present teams with relevant information and mitigate opportunities for human error. **Value addition:** API management tools help companies that publish APIs to get the most value out of them. Enterprise-grade monetization tools lay the foundation for such value, allowing businesses to profit effectively when clients call their APIs. Actionable API usage metrics such as traffic trends, issue reporting, and more give teams crucial data, which can then be leveraged to inform product development and improvement. Some API management tools also include features that can help attract developers, like intuitive developer portals.    ### Who uses API management tools? **Developers:** A company’s API will typically be written and managed by its developers and development teams. Thus, developers will be the ones making the most of API management solutions. API management software offers full lifecycle control over managing APIs, so developers shouldn’t need to work outside the solution to oversee their published APIs. **Development managers:** Development managers can benefit from API management software's reporting and analytics features. These solutions offer insights that can help managers make more informed decisions, driving current and future projects toward greater success. ### Software related to API management solutions Related solutions that can be used together with API management platforms include: [API design software](https://www.g2.com/categories/api-design) **:** API design software allows users to plan, create, and change APIs in a secure development environment. These tools help handle API preproduction management by enabling developers to ideate, set design guidelines, and ultimately build APIs under one dashboard. Consequently, API management software allows users to handle post-production management. [API marketplace software](https://www.g2.com/categories/api-marketplace) **:** API marketplaces aggregate APIs and provide a place for application developers to upload, distribute, and monetize their APIs while also providing a space for consumers to discover and implement APIs for their products. These tools can work in tandem with API management software to create a full API monetization solution. [API security software](https://www.g2.com/categories/api-security) **:** API security software protects information traveling through a company’s network via APIs. Companies use API security technologies to develop an inventory of existing API connections and ensure their security. Unlike API management software, API security software can apply to both internal and external APIs. [Cloud communication platforms:](https://www.g2.com/categories/cloud-communication-platforms) Cloud communication platforms provide tools for mobile developers to connect their mobile apps to a phone’s SMS, voice, and verification features via APIs. Developers use these products to add communication capabilities such as text notifications, user-to-user chatting, and voice connectivity to their applications. Many companies that provide cloud communication platforms use API management software as a vital way to organize and maintain their communication APIs.  ### Challenges with API management software Software solutions can come with their own set of challenges.  **Security:** API management solutions must either include or be paired with security solutions to verify no security holes with API code, implementation, or use. Following API security protocols when implementing an API management solution is essential. Authorization checks must be used when necessary. **Other DevOps integrations:** API development must be considered part of a company’s other DevOps efforts. In line with this consideration, API management tools need to be able to integrate with whatever other DevOps software the company uses. It’s important to check if these integrations exist. If they don’t, companies must find a workaround or consider a different solution entirely. ### Which companies should buy API management software? **Software development companies:** Any software development company that offers access to custom-built APIs benefits from the use of API management software. The number of APIs a company oversees can grow quickly, so the ability to manage them all within a single dashboard ensures proper oversight and efficient monetization. API management tools help software development companies of all sizes by improving operational efficiency and organization.  ### How to choose the best API management tool #### Requirements Gathering (RFI/RFP) for API Management Software [G2.com](https://www.g2.com/) can assist buyers in finding the best API management software tool, whether a buyer is searching for API management tools for the first time or looking to replace legacy software. Generally, the most important considerations are price, feature set, and ease of integration. One of the main purposes of API management software is to make API management more convenient, so ensuring that the tool of choice integrates well with the company’s existing software stack is often essential. Using G2 reviews as a reference, buyers can determine the features that will best help them manage their APIs effectively, ensuring a pain-free integration with their existing tools.  After narrowing down a potential pool of products, teams can then apply further considerations for budget, security requirements, and more. Using this approach, buyers can confidently move forward in the buying process, referencing their checklist in conjunction with G2 scores to find the right solution for their needs. #### Compare API Management Software Products ##### **Create a long list** Buyers should consider the many API management solutions on the market. Some include API design functionality to provide users with a complete API lifecycle solution, while others exist separately from the preproduction process and instead integrate with other API design tools. Buyers should consider options like these to produce a long list of potentially viable products. ##### **Create a short list** Once a long list is created, buyers should employ a more granular approach to trim it down. Along with a matrix of must-have functionality and pricing, buyers can use G2 reviews to explore any potential advantages and disadvantages among the products they’re considering. With these factors in mind, buyers should narrow their search to three to five products. ##### **Conduct demos** All software products on a company’s short list need to be investigated firsthand via demos to ensure that real-time functionality matches on-paper expectations. During demos, buyers should make inquiries based on the requirements gathering they’ve done prior; for example, one might ask to be walked through an API management tool’s security features to ensure the company’s needs will be met.  #### Selection of API Management Software ##### **Choose a selection team** Companies of any size should try to involve the most relevant personas when beginning the API management software selection process. Large companies might have the resources to include individual team members to fill roles such as project manager, decision maker, system owner, and developer. Smaller companies can overlap roles to compensate for their relatively fewer employees.  ##### **Negotiation** Some vendors offer API management platforms that can do far more than what the buyer requires, such as API design or a hosted API marketplace. While some vendors may only offer an all-or-nothing package, buyers who want to optimize spending should try to negotiate a fairly priced package that includes only the functionalities that matter to them. For example, a product’s pricing page could show that the buyer’s must-have features are only included with an expensive all-in-one package, whereas a sales conversation may prove otherwise.  ##### **Final decision** To conclude the process, performing a trial run with a small pool of developers is essential. This will aid buyers in making sure that their chosen API management software integrates well with a developer’s workflow. If the API management tool is received well and utilized often, the buyer’s selection is probably the right one. If not, it may be time to try another product from the short list.
