Kong Inc. Review: Overview, Features, Pricing & Alternatives in 2025

APIs shouldn’t drain your time and sanity.

If you’re evaluating API management platforms, you know just how messy API sprawl, security risks, and unreliable services can get—especially as your architecture grows or your team moves toward microservices.

But here’s the everyday reality: Managing all those APIs with homegrown tools means constant fire-fighting and missed deadlines. You’re tired of being stuck in the weeds fixing issues instead of building value.

Kong Inc. offers a serious upgrade here, with integrated tools for API gateway management, API lifecycle workflows, microservices connectivity, and robust testing—all in one extensible platform. Their approach lets you unify, secure, and scale your APIs while staying developer-friendly and future-proof.

In this review, I’ll break down how Kong Inc. helps you regain API control—from their core features and new AI Gateway, to deployment options, real-world pricing, and competitive alternatives.

Throughout this Kong Inc. review, you’ll see clear breakdowns of strengths, gaps, and exactly what to expect if you’re thinking about a free trial or demo.

You’ll get the features you need to make a smart decision without any guesswork.

Let’s get started.

Kong Inc. Overview

Kong Inc. has been a key player in API infrastructure since 2009. From their San Francisco base, they focus on helping you connect, secure, and scale your digital services.

What I’ve noticed is they strongly target mid-market and enterprise organizations that are serious about their API strategy. Their specialty is providing a universal connectivity layer, a fantastic fit for businesses modernizing their architecture and adopting complex, distributed systems.

Their acquisition of Insomnia and new AI Gateway show a clear innovation path. Through this Kong Inc. review, you can see how these moves simplify modern developer workflows from start to finish.

Unlike tools deeply embedded with one cloud provider, Kong is proudly platform-agnostic. I find their key strength is helping you avoid vendor lock-in, a major advantage for any business that runs a multi-cloud or hybrid IT strategy.

They work with major enterprises like GSK and Nasdaq, which gives me real confidence. This shows their platform is trusted to handle demanding, mission-critical API traffic and sophisticated security requirements at scale.

I believe their current strategic focus is centered on delivering a unified management plane with Kong Konnect. For your team, this means gaining consistent, centralized control over your increasingly complex microservices and API products.

Now, let’s examine their core capabilities.

Kong Inc. Features

Worried about managing complex API ecosystems?

Kong Inc. features offer an integrated suite for managing, securing, and scaling your APIs and microservices. Here are the five main Kong Inc. features that address critical API challenges.

1. Kong Gateway

Dealing with unmanaged API traffic?

Without a central entry point, securing and routing API requests can become chaotic. This leads to vulnerabilities and poor performance.

Kong Gateway acts as your API traffic controller, handling routing, load balancing, and security through powerful plugins. From my testing, its extensibility with various authentication and rate-limiting features truly stands out for protecting your APIs. This core feature supports multiple protocols, making it incredibly versatile.

This means you gain robust control over your API interactions, enhancing both security and reliability.

2. Kong Konnect

Struggling with fragmented API management?

Managing APIs across different environments can be a disjointed, frustrating experience. This often leads to inconsistency and operational overhead.

Kong Konnect provides a unified console to oversee your entire API lifecycle, from gateways to service meshes. What I love about this approach is how it centralizes management, offering a service catalog and developer portals for streamlined access. It supports both cloud and hybrid deployments.

You can finally achieve consistent API governance and empower developers with easy access to your services.

3. Kong Mesh

Is microservice communication a security nightmare?

Connecting microservices securely and reliably in distributed environments is a huge headache. This often results in complex, error-prone configurations.

Kong Mesh, built on Kuma, simplifies microservice management by offering zero-trust security, traffic reliability, and global observability. Here’s what I found: it provides built-in mTLS and advanced traffic control that significantly enhances inter-service communication. This feature supports both Kubernetes and VMs.

The result is your team gets unparalleled control over service connectivity, ensuring secure and resilient applications.

4. Kong Insomnia

Tired of cumbersome API design and testing?

Inefficient API design and testing workflows can seriously bottleneck your development cycle. This often leads to delays and quality issues.

Kong Insomnia provides an all-in-one platform for designing, testing, mocking, and debugging HTTP-based APIs. This is where Kong Inc. shines; its ability to create API mocks before backend completion truly accelerates development. This feature also includes robust automation and collaboration tools.

So you can accelerate your API development and ensure high-quality APIs from the get-go.

5. Kong AI Gateway

Building AI services feel like a complex puzzle?

Integrating and managing generative AI capabilities within your existing infrastructure can be daunting. This often leads to slow deployment and limited control.

The Kong AI Gateway is designed to simplify building and deploying generative AI services, supporting multi-LLM implementations. From my evaluation, it aims to provide advanced AI prompt engineering and observability, making AI integration manageable. This feature supports no-code AI use cases.

This means you can quickly leverage AI in your applications with enhanced security and performance.

You’ll actually appreciate how these Kong Inc. features work together to create a comprehensive API and microservices management platform rather than separate tools.

Best Kong Inc. Alternatives

Seeking the best API management solution?

The best Kong Inc. alternatives include several strong options, each better suited for different business situations and priorities regarding cloud strategy, integration needs, and budget.

1. Microsoft Azure API Management

Already invested heavily in the Azure ecosystem?

Azure API Management excels when your infrastructure is deeply embedded in Microsoft Azure, offering a fully managed service that simplifies operational overhead. From my competitive analysis, Azure is ideal for Azure-centric organizations prioritizing seamless cloud integration over multi-cloud flexibility or open-source control.

Choose this alternative if your primary focus is a fully managed, cost-predictable solution within Azure.

2. Amazon API Gateway

Building serverless applications primarily on AWS?

Amazon API Gateway is a great fit if your operations are predominantly on AWS and you aim for a serverless API architecture, benefiting from native integrations. What I found comparing options is that AWS API Gateway is highly cost-effective for high volumes within the AWS ecosystem, supporting a pay-as-you-go model.

Consider this alternative when your architecture is AWS-first and you seek extreme scalability for API calls.

3. MuleSoft (Salesforce)

Requiring a broad enterprise integration platform?

MuleSoft is the better choice if your organization needs a comprehensive iPaaS alongside API management, especially for complex enterprise integrations. From my analysis, MuleSoft offers a unified platform for integration and APIs, though it typically represents a higher investment than a pure API gateway.

Choose MuleSoft when extensive application and data integration is as critical as API management.

4. WSO2 API Manager

Prioritizing an open-source, self-managed solution?

WSO2 API Manager is ideal if you possess the internal resources to manage an open-source platform and desire comprehensive API lifecycle features out-of-the-box. Alternative-wise, WSO2 provides a free, feature-rich open-source option for those willing to handle its deployment and ongoing management.

Consider WSO2 if a free, full-featured open-source solution with self-management capabilities aligns with your strategy.

The best Kong Inc. alternatives depend heavily on your existing cloud infrastructure and integration requirements, so evaluate based on your strategic priorities.
