What API management do
API management platforms sit between API consumers and backend services. They provide a gateway that enforces authentication, rate limits and routing, a developer portal for onboarding, and analytics and governance. Many now add AI and MCP gateways for LLM and agent traffic.
Who uses them: Platform and DevOps teams running many APIs, Enterprises exposing APIs to partners, SaaS companies productising APIs, Teams governing AI and agent traffic, Developers building on unified email or calendar APIs (the two high-volume lineup entries).
Price range: Entry points range from free to 25 USD a month plus usage (Kong Plus), about 50 to 150 USD a month for Azure Developer and Basic, about 365 to 3,431 USD a month per environment for Apigee pay as you go, and 2,000 USD a month billed annually for MuleSoft. Enterprise tiers at all five are quote-based.
What to check before you buy
Pricing model and entry cost. Kong Plus starts at 25 USD a month plus usage, Azure Consumption is pay per call, Apigee's lowest environment is about 365 USD a month, MuleSoft starts at 2,000 USD a month billed annually, Tyk is quote only.
. Apigee, Azure APIM and MuleSoft are tied to their vendor platforms.
Deployment flexibility. Hybrid and self-hosted gateways exist at Kong, Tyk, Apigee (Enterprise), Azure (Developer, Premium) and MuleSoft.
Developer portal. Portal limits differ: Kong Plus max 2, Azure has none on Consumption, Apigee and Tyk include portals in paid tiers.
AI and MCP governance. All five now market MCP or AI gateway features; check what is GA and which plan includes it.
How we test API management
The test for this category: Put the same 3 APIs behind each gateway; setup, rate limiting, analytics, latency added.
Each tool is used to build the same small reference app or integration from the docs (for example a to-do API with auth, a site search over 10,000 products, a scraper for 1,000 pages). AI coding assistants get the same 20 coding tasks in a sample repository.
Each tool is tested on a paid plan, and its review shows the plan, the price and the test dates. The overall score is the average of the five parts on the right, rounded to the nearest half star. See the full method for developer platforms and APIs tools.

Frequently asked questions
What is API management?
Tools that run a gateway in front of APIs for security, rate limits and routing, plus a developer portal, analytics and governance.
What is the difference between an API gateway and API management?
A gateway handles runtime traffic; API management adds portal, analytics, lifecycle and monetization around it.
How much does API management cost?
Apigee environments run about 365 to 3,431 USD a month.
Do API management tools support AI agents and MCP?
Kong, Apigee, Azure APIM, MuleSoft and Tyk all list MCP or AI gateway features as of 2026.

I've never been impressed by software simply because it looks modern. I'm far more interested in what happens when you actually start using the platform.
