API Management: Feature Set Comparison


Previously, we talked with founder of Varnish, Per Buer about the advancements Varnish has made over the past couple years and how they continue to grow in the market of open source caching. But one topic that came up was how Varnish’s API Engine compares to the likes of legacy API Engines such as Tibco Mashery, Apigee, Kong and Tyk. Buer related how Varnish manages to stack up to these when it comes to performance, but that they may contain richer feature sets. Given the assertion, we decided to follow up with a side by side comparison of the four API Engines to shed light on the competition in the API market.

The World of APIs

Tibco Mashery

Last year in August TIBCO Software, which specialized in analytics, integration and event processing, announced that they acquired Mashery, an API management company. The goal of the acquisition, as told by the company’s press release, was to expand TIBCO’s API management solutions “to help enterprises transform into digital businesses, integrate more channels for new services and experiences, and empower developers to accelerate innovation.”

Mashery already had a strong track record in the world of API Management, being named the leader in Application Services Governance Magic Quadrant by Gartner. Now with TIBCO, they continue to expand on their API engine with an extensive feature set.

  • API Portal: Allows you to create a customizable portal for enrolling and supporting partners
    • Provisioning tactics that lets you issue live keys or require activation by a moderator for security
    • Mashery I/O Docs lets developers execute calls directly from API documents. It also shows them how many calls they’re making, the methods they’re using, and so on
  • API Security: PCI-Compliant for data security, HITRUST CSF Certified to handle health information, SSAE 16 SOC 2 Type 1 compliant
    • Also have OAuth 2.0 accelerator for secure access to sensitive user data and SSL support
  • API Analytics: Helps to identify key trends and behaviors that impact business, while gaining a deeper understanding of API traffic, performance and growth.
    • Helps make reports more user friendly, transporting raw data into more visible insights
    • Provides you with the information to scale your API Management infrastructure, uncover new business outlets and so on.
  • API Traffic: Offers three types of infrastructure
    • Cloud: global PoPs, dynamic scaling and monitoring features, fast time to market, focus on core competency
    • Local: Fully integrated central dashboard for API policies, management and reporting. Removes network latency, internal traffic situation, with on-premise security and control.
    • Hybrid: Contains a single integrated Web dashboard for access policy configuration, partner administration and reporting. Ultimate flexibility, “single pane of glass” control, right tools for various use cases
  • API Packager: Helps give management teams the power to negotiate custom API access, reduce work for IT, and provides fine-tune resources.
    • With the packager no coding is required, allowing for business-side product creation with lifecycle management and response filters.


At the top of the list for most API management needs, is Apigee who has been recognized by Gartner for both “ability to execute” and “completeness of vision.“  They handle billions of API calls with almost 100% availability, with features as follows:

  • Apigee Edge: API management platform to help you build and scale your network with security, comprehensive analytics and apps.

There seems to be two separate spectrums here with the feature sets–fully integrated support or freedom with open source. TIBCO Mashery and Apigee are by far larger, with a more extensive list of features, but this comes at a higher cost compared to open source alternative like Kong and Tyk. Depending on your company and you specific API needs, certain feature might draw you in more so than others, but know that there are several options out there, more than we can profile, so there’s always an alternative to fit your needs.
