The best API management tools, tested and ranked

Azure API Management came first of seven with 4.5 out of 5, and scored a full 5 for features. It was the fastest to set up, at 67 minutes to a first working result, passed 27 of 30 gateway checks, got all 15 rate-limit rules right and added just 25 milliseconds of delay to the slowest 5% of requests. Its docs passed 9 of 10 checks. Our Azure review has the full results.

It's Microsoft's managed service for publishing and securing APIs, with a gateway and an open-source developer portal. Tiers run from pay-per-call Consumption, where the first 1 million operations are free, to multi-region Premium. It links closely with Entra ID, Key Vault and Azure Monitor, and its MCP governance has been generally available since November 2025.

The catches sit outside our test: it ties you to Azure, its rules are written in XML, and users on G2 say the bigger tiers are costly for small teams. It has 4.1 out of 5 on Gartner Peer Insights from 230 reviews (checked November 2026).

Kong came second with 3 out of 5. It took 115 minutes to a first working result, passed 18 of 30 gateway checks and got 11 of 15 rate-limit rules right, the best of the chasing pack. It added 78 milliseconds of delay to the slowest 5% of requests, lowest after Azure, and passed 4 of 5 export checks. But only 3 of 5 setup examples worked. Read our Kong review.

Kong is built on the open-source Kong Gateway. Its paid platform, Konnect, manages API, AI and event gateways that run in Kong's cloud or in your own Kubernetes or data centre. Plus is pay as you go from $25 a month plus usage, and Enterprise is quoted yearly.

Users praise its plugins and flexibility, rating Kong Gateway 4.5 out of 5 from 153 reviews on Gartner Peer Insights (checked November 2026), but mention docs gaps, a steep learning curve and cost.

MuleSoft came third with 3 out of 5, level with Kong. It reached a first working result in 110 minutes, quickest after Azure, and 4 of 5 setup examples worked. As a gateway it was average: 18 of 30 checks passed, 10 of 15 rate-limit rules worked and it added 92 milliseconds of delay at the slow end. Our MuleSoft review explains more.

MuleSoft, owned by Salesforce, is an integration platform first and an API management tool second. Its Anypoint tools connect apps, then govern traffic through API Manager and Omni Gateway, including Agent2Agent and MCP traffic. Pricing moved to packages paid in Mule Credits in 2026, from $2,000 a month, billed yearly.

Users rate it 4.6 out of 5 on Gartner Peer Insights from 394 reviews and 4.5 on G2 from 774 (both checked November 2026), mainly for its connectors. The usual complaints are cost and a steep learning curve.

Aurinko came fourth with 3 out of 5. It isn't an API gateway, so read its results with that in mind. It took 111 minutes to a first working result, passed 18 of 30 gateway checks, got 9 of 15 rate-limit rules right and added 86 milliseconds of delay at the slow end. Moving away would take 2 manual steps. Our Aurinko review has the details.

Aurinko sells one API that lets your app read and write users' email, calendars, contacts and tasks across Google, Microsoft and other providers, plus Bright Sync, ready-made logic to keep that data in step with a CRM. You pay per connected account, from $1 a month for each account under 1 GB of transfer.

We found no user ratings or security certifications on the pages we read, so ask for compliance details first.

Apigee came fifth with 2.5 out of 5, scoring 2.5 on every part. It took 119 minutes to a first working result, passed 18 of 30 gateway checks and set up only 9 of 15 rate-limit rules correctly. Its docs passed 6 of 10 checks, though it added a modest 90 milliseconds of delay at the slow end. More in our Apigee review.

Apigee is Google Cloud's API management platform, with security rules, analytics, a developer portal and an optional add-on for charging for your APIs. It runs as a Google-managed service or on your own Kubernetes on the Enterprise tiers, and can offer APIs as MCP tools for agents.

Price is the hurdle. Pay as you go is charged by the hour per active environment, from about $365 a month per region before calls, even when idle, and subscriptions have no public price. Users give it 4.5 out of 5 on Gartner Peer Insights from 318 reviews (checked November 2026).

Tyk came sixth with 2.5 out of 5. It passed 18 of 30 gateway checks, got 10 of 15 rate-limit rules right and added only 84 milliseconds of delay at the slow end. Getting started was the problem: 140 minutes to a first working result, joint-slowest, and its docs passed only 5 of 10 checks, so developer experience was its weakest part at 2. Our Tyk review has the full story.

Tyk's gateway is free and open source under MPL 2.0, self-hosted or on Tyk Cloud. The dashboard, developer portal and multi-data-centre sync need a paid license, sold only by quote. If a license lapses, existing APIs keep running, but you can't create or change them until you renew.

It lists ISO 27001 and SOC 2, the clearest security list among the gateways here. Users rate it 4.7 out of 5 on Gartner Peer Insights from 92 reviews and 4.6 on G2 from 40 (both checked November 2026).

Nylas came last with 2 out of 5, scoring 2 on every part. Like Aurinko, it isn't a gateway, and it struggled with our gateway tasks: 15 of 30 checks passed, only 7 of 15 rate-limit rules worked and it added 102 milliseconds of delay at the slow end, the most in the test. Our Nylas review explains more.

Nylas gives developers one API for users' email, calendars and contacts, plus a Scheduler, a meeting Notetaker and Agent Accounts. Its free plan includes full API access for 5 accounts with no card, which makes prototyping easy. Paid plans start with Essentials at $15 a month.

Users are split: 4.0 out of 5 on G2 from 60 reviews, but 2.2 on Trustpilot from 8 (both checked November 2026), with complaints about charges after cancelling.
