The 16 tools, reviewed
#1 Zuplo
Edge-native API gateway configured as code · United States · zuplo.com
Edge deployment Config as code Transparent pricing
Zuplo's whole design argument is that a gateway should deploy like an application: routes and policies live in a config file, changes go through a normal pull request and CI pipeline, and the result runs on edge infrastructure with no server for the team to patch.
- Pricing: Usage-based. Free plan covers 100,000 requests a month. Free plan: free plan.
- Best for: Small engineering teams shipping API-first products
- Strengths: OpenAPI-driven gateway config; Git-based deployment; Developer portal.
Where it falls short
The company is young and its governance catalog is thinner than larger enterprises expect from an API management purchase.
Wrong for
A large enterprise managing hundreds of APIs across many teams with formal governance requirements needs a deeper catalog than Zuplo currently offers, and pays extra for its audit logs and access controls.

#2 Tyk
Open-source gateway with GraphQL federation, self-host or cloud · United Kingdom · tyk.io
Open-source gateway GraphQL federation Self-hosted first
Tyk built its reputation on shipping a real, unrestricted open-source gateway rather than a crippled trial version of the commercial product, and that continues to be its strongest argument.
- Pricing: Open source + paid tiers. Tyk Gateway is free and open source to self-host. Free plan: open source.
- Best for: Teams standardizing on self-hosted infrastructure
- Strengths: API gateway; GraphQL federation; Developer portal.
Where it falls short
The admin interface is less polished than newer, design-forward competitors, and some configuration still happens through raw JSON rather than a guided flow.
Wrong for
A team with no engineer willing to own gateway operations, and no interest in GraphQL, will find simpler managed options elsewhere.

#3 Sensedia
API management specialized in open banking and open finance · Brazil · sensedia.com
Open finance specialist Latin America focus ISO 27001 certified
Sensedia's most defensible advantage is not a general gateway feature but a specific one: it has built and maintained first-class support for Brazil's open finance mandate, including the consent-management and mutual-TLS auth flows the regime requires, well ahead of most competitors that treat regulated finance as a custom implementation project rather than a shipped product feature.
- Pricing: Quote only. Quote-only enterprise contracts, sold through a direct sales and implementation engagement rather than self-serve signup. Free plan: none.
- Best for: Financial institutions in Latin America
- Strengths: API gateway; Open banking/open finance connectors; Developer portal.
Where it falls short
Brand recognition and community size outside Latin America are limited, documentation and support are strongest in Portuguese and Spanish-speaking markets, and a company outside financial services or outside the region gets little benefit from Sensedia's core specialization.
Wrong for
A company outside Latin American financial services, with no open banking obligation, will find broader, better-known gateways a more natural fit.

#4 Gravitee.io
Open-source API gateway, governance and developer portal · United States · gravitee.io
Open-source core API governance Developer portal
Gravitee earns the top spot because it does not force a choice between running an open-source gateway and having a usable governance layer on top of it.
- Pricing: Open source + paid tiers. Open-source Community Edition is free to self-host. Free plan: open source.
- Best for: Teams running many internal and partner APIs
- Strengths: API gateway; Policy studio; Developer portal.
Where it falls short
Advanced policies, the AI gateway mode and multi-region control plane deployment are held back for the Enterprise tier, and only the entry Planet tier has a published price ($2,500 a month for a single production gateway).
Wrong for
A team that wants a single managed SaaS gateway with no self-hosting option at all should look elsewhere, since Gravitee's strongest economics come from running the open-source core yourself.

#5 Kong
Dominant open-source gateway with a large plugin ecosystem · United States · konghq.com
Largest install base Kubernetes-native Deep plugin ecosystem
Kong Gateway is the API gateway most platform engineers have already run at some job, and that familiarity, combined with the largest plugin catalog in this category, makes it the safe default for a team standardizing on Kubernetes.
- Pricing: Open source + paid tiers. Kong Gateway is free and open source. Free plan: open source.
- Best for: Platform teams already running Kubernetes
- Strengths: API gateway; Kubernetes Ingress Controller; Konnect control plane.
Where it falls short
The line between what is free in Kong Gateway and what requires an Enterprise license is not always obvious until a team hits it mid-project, and several of the most useful plugins (advanced rate limiting, some auth methods) are commercial-only.
Wrong for
A small team with no Kubernetes footprint and no appetite for plugin sprawl will find Kong more machinery than the job needs.

#6 Postman
API platform for design, testing and governance, with gateway features · United States · postman.com
Design-first Huge existing user base Governance add-on
Postman's enormous existing footprint in API design and testing gives it a natural path into governance: because so many teams already write and share their OpenAPI specs inside Postman, adding linting rules, a spec catalog and gateway integrations meets developers where they already work rather than asking them to adopt a second tool.
- Pricing: Per user / month. Free plan for a single user. Free plan: free plan.
- Best for: Teams already standardized on Postman for API design
- Strengths: API design and documentation; Collection-based testing; API governance rules.
Where it falls short
The gateway and runtime traffic-management features are less mature than purpose-built gateways, and teams needing serious rate limiting, transformation or multi-region routing at production scale will find the runtime layer underpowered.
Wrong for
A team whose primary need is production traffic management, not design and testing, should pick a runtime-first gateway.
Visit Postman →
#7 Azure API Management
Microsoft's API gateway and management layer inside Azure · United States · azure.microsoft.com
Azure-native Hybrid gateway Entra ID integration
Azure API Management is the reasonable default for an enterprise that already runs its infrastructure on Azure, because it inherits identity, networking and monitoring from the rest of the platform instead of requiring a separate integration project.
- Pricing: Usage-based. Classic (Developer, Basic, Standard, Premium) and v2 tiers billed per unit per month, plus a Consumption tier billed per call with the first million operations a month included. Free plan: free trial.
- Best for: Enterprises already standardized on Azure
- Strengths: Managed and self-hosted gateway; Developer portal; Azure Entra ID integration.
Where it falls short
The XML-based policy pipeline has a real learning curve compared with newer products built around OpenAPI and code-first config, and the console can feel like it was designed for an Azure administrator rather than an API developer.
Wrong for
A multi-cloud company with no particular Azure commitment gets little benefit from the deep platform integration that is this product's main selling point.

#8 AWS API Gateway
Serverless-native API gateway for AWS workloads · United States · aws.amazon.com
Serverless-native Lowest cost at low volume AWS-only
AWS API Gateway is the obvious choice for a team already building on Lambda and other AWS services, because it wires into IAM, CloudWatch and the rest of the AWS control plane without a separate account or integration step, and its per-call pricing is genuinely inexpensive at moderate volume.
- Pricing: Usage-based. Pay-as-you-go per million calls, from $1.00 for HTTP APIs and $3.50 for REST APIs. Free plan: free trial.
- Best for: AWS-native teams building on Lambda
- Strengths: REST and HTTP API gateway; WebSocket API support; Lambda and AWS service integration.
Where it falls short
The built-in developer portal covers only REST APIs in a single region, so HTTP and WebSocket APIs, cross-region catalogs and broader API governance have to be built or bought separately, which raises the real cost of a full management setup above the advertised per-call price.
Wrong for
A company publishing HTTP or WebSocket APIs, or APIs spread across regions, to external partners will find the REST-only, single-region portal too narrow.

#9 Google Apigee
Enterprise API platform with monetization and deep analytics · United States · cloud.google.com
Deep analytics API monetization Enterprise-scale
Apigee's origins as a standalone API analytics company show in how much more detail it exposes about API consumption than most competitors: cohort analysis of developers, revenue reporting for monetized APIs, and traffic anomaly detection are genuinely deeper here than elsewhere in this list. Google acquired the product specifically to compete at the top of the enterprise market, and it shows in the roadmap around AI-assisted spec design and multi-region hybrid deployment for companies not fully committed to Google Cloud.
- Pricing: Usage-based. Pay-as-you-go billing per million API calls ($20 for Standard and $100 for Extensible proxies at the lowest band) plus a per-region environment fee from $365 a month. Free plan: free trial.
- Best for: Large enterprises monetizing APIs as a product
- Strengths: API gateway (hybrid or cloud); Developer portal; API monetization and billing.
Where it falls short
The pricing and packaging are dense enough that most buyers need a sales conversation to understand what a real deployment will cost, monetization and hybrid deployment are not available on pay-as-you-go, and the platform's monetization and analytics depth is wasted on a company that is not actually selling API access as a product.
Wrong for
A team that just needs auth, rate limiting and a developer portal, without monetization or deep analytics, is paying for capability it will not use.
Visit Google Apigee →
#10 MuleSoft Anypoint Platform
Enterprise integration platform with API management built in · United States · mulesoft.com
Full integration suite Salesforce-owned Enterprise contracts
MuleSoft's API Manager is genuinely capable, but it is sold and used as part of a much larger integration platform rather than as a standalone gateway purchase, which is exactly the point for an enterprise that is buying Anypoint to connect Salesforce, SAP, mainframes and everything in between and wants API governance folded into that same contract.
- Pricing: Quote only. Quote-only annual contracts, typically bundling API management with the platform's broader integration and connector licensing. Free plan: free trial.
- Best for: Large enterprises doing broad systems integration
- Strengths: API Manager; Anypoint Design Center; Pre-built connectors.
Where it falls short
Buying API management here effectively means buying the integration platform around it, which is a heavier and more expensive commitment than a company only wanting a gateway should take on.
Wrong for
A company that only needs a gateway and developer portal, with no broader integration platform requirement, is buying far more product than the job calls for.

#11 IBM API Connect
Enterprise API gateway with hybrid and mainframe integration · United States · ibm.com
Hybrid deployment Mainframe integration Long track record
IBM API Connect has been in this market long enough to have built genuinely deep hybrid deployment options, including the ability to front mainframe and legacy IBM middleware transactions with a modern REST or GraphQL interface, which is a real and specific capability few competitors bother to maintain.
- Pricing: Quote only. Sold as pay-as-you-go SaaS on AWS, annual SaaS subscriptions (Standard, Premium, Reserved Instance) and self-managed software. Free plan: free trial.
- Best for: Enterprises with existing IBM middleware
- Strengths: API gateway (cloud, on-prem or hybrid); Developer portal; API Manager console.
Where it falls short
The console and configuration model show their age next to gateways built in the last five years, licensing is opaque without a direct sales conversation, and smaller teams report a longer time to a first working API than with lighter competitors.
Wrong for
A company with no existing IBM footprint and no mainframe integration need will find lighter, faster-to-deploy products a better match.
Visit IBM API Connect →
#12 SAP API Management
API gateway inside SAP Business Technology Platform · Germany · sap.com
SAP BTP-native S/4HANA integration Consumption billing
SAP API Management is really a module of SAP Integration Suite, and it is a sensible default for a company that already runs S/4HANA and BTP, since it ships pre-built connectors to SAP's own APIs and bills through a BTP contract a customer already has.
- Pricing: Usage-based. Consumption-based pricing through SAP BTP credits, billed per API call volume against a company's existing BTP contract. Free plan: free trial.
- Best for: Enterprises running SAP BTP and S/4HANA
- Strengths: API gateway (part of Integration Suite); Developer portal; Pre-built SAP API connectors.
Where it falls short
Outside the SAP ecosystem this is a weak general-purpose gateway.
Wrong for
A company with no SAP footprint should not consider this product.
Visit SAP API Management →
#13 WSO2
Open-source API management with strong on-premises support · Sri Lanka · wso2.com
Open-source stack On-premises option Now PE-owned
WSO2 built its business on shipping a complete, genuinely open-source API management stack years before that was a common strategy, and the product still shows that discipline: governance, identity and gateway components are designed to work together rather than bolted on after an acquisition.
- Pricing: Open source + paid tiers. WSO2 API Manager is free and open source to self-host. Free plan: open source.
- Best for: Regulated enterprises needing on-premises deployment
- Strengths: API gateway; Developer portal; API governance and lifecycle.
Where it falls short
The developer experience and documentation trail newer, venture-backed competitors, and the interface across the stack's several components feels less unified than a product built from one codebase.
Wrong for
A small team wanting the fastest path to a first live API, with no regulatory requirement to self-host, will find the setup heavier than Zuplo or Tyk Cloud for no corresponding benefit.

#14 Axway Amplify
Legacy-integration-focused API management, part of listed 74Software · France · axway.com
Legacy integration Part of 74Software Enterprise contracts
Axway grew out of a 2011 spinoff from Sopra Group and has spent the years since specializing in exactly the kind of integration work newer, cloud-native gateways avoid: fronting mainframes, managed file transfer and older B2B protocols with a modern API layer.
- Pricing: Quote only. Quote-only enterprise licensing, typically structured as an annual contract sized to deployment volume. Free plan: none.
- Best for: Enterprises modernizing legacy and mainframe systems
- Strengths: API gateway; Developer portal (API Central); Managed file transfer integration.
Where it falls short
The product suite feels assembled from several product lines built at different times rather than one coherent platform, and the console is noticeably less modern than newer entrants in this list. Licensing is opaque without a sales conversation, and the company's growth has been slow relative to the venture-backed vendors it competes against, which shows in a smaller pace of new feature releases.
Wrong for
A company with no legacy or mainframe integration need, building purely cloud-native APIs, gets no benefit from Axway's core specialization and will find faster, cheaper options elsewhere in this list.
Visit Axway Amplify →
#15 Akana
Enterprise API lifecycle management under Perforce · United States · perforce.com
API lifecycle governance Perforce-owned Enterprise licensing
Akana has a long history in API lifecycle governance, the formal process of designing, reviewing, versioning and retiring APIs on a defined schedule, and that discipline is still its strongest feature for an enterprise that needs an audit trail on every API decision rather than a fast-moving startup workflow.
- Pricing: Quote only. Quote-only enterprise licensing, sold as part of Perforce's broader DevOps and API lifecycle product line. Free plan: free trial.
- Best for: Enterprises wanting formal API lifecycle governance
- Strengths: API gateway; Developer portal; API lifecycle governance.
Where it falls short
Product development has slowed visibly since the acquisition, with fewer independent releases than the actively developed open-source and venture-backed products in this list, and the interface has not kept pace with newer competitors.
Wrong for
A team wanting an actively evolving product with a fast release cadence, or any self-serve entry point, will be better served by Gravitee, Tyk or Zuplo than by a product now positioned as one line item in a larger Perforce contract.
Visit Akana →
#16 API7
Commercial platform built on the open-source Apache APISIX gateway · Singapore · api7.ai
Apache APISIX steward High-performance gateway Open source
Apache APISIX, the open-source project API7 stewards, has a genuine performance reputation, built on NGINX and etcd for low-latency routing, and has grown into a top-level Apache Software Foundation project with adoption well beyond API7's own customer base, including multi-protocol support for gRPC, MQTT and WebSocket traffic that most gateways in this list do not handle natively.
- Pricing: Open source + paid tiers. Apache APISIX is free and open source under Apache 2.0. Free plan: open source.
- Best for: Teams already running Apache APISIX
- Strengths: API gateway (Apache APISIX); AI gateway plugins; Developer portal.
Where it falls short
API7 Cloud's commercial track record and support presence are thinner than the long-established gateway vendors above it, documentation for the managed product lags the open-source project's own docs, and enterprise buyers with strict vendor-diligence requirements may need to do more legwork evaluating the company than with better-known incumbents.
Wrong for
An enterprise that needs an established support organization with a long regional track record and formal SLAs will find the surrounding commercial layer newer than the underlying open-source gateway.

Questions and answers
What is the best API management software in 2026?
Zuplo ranks first of 16, best for small engineering teams shipping API-first products. Tyk is second (teams standardizing on self-hosted infrastructure) and Sensedia third (financial institutions in Latin America). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Do we need a dedicated API gateway, or can our cloud provider's built-in option cover it?
If every API you run lives on one cloud and stays there, the built-in gateway (Azure API Management, AWS API Gateway or Google Apigee) removes a vendor relationship and bills alongside the rest of your cloud spend, which is a reasonable starting point.
What is the difference between an API gateway and full API management?
A gateway is the runtime component that sits in the traffic path enforcing auth, rate limits and routing; API management is the broader product, which adds a control plane for defining those policies, a developer portal for publishing documentation and issuing keys, and analytics on usage.
Should the API gateway also handle service-to-service traffic inside our own systems?
Usually not with the same product.
How hard is it to migrate an existing set of APIs onto a new gateway?
It depends almost entirely on how the current routing, auth and rate-limit rules are documented.
Is open source enough, or do we need the commercial version?
Open-source cores from Kong, Tyk, Gravitee, WSO2 and API7 handle routing, auth and rate limiting competently and are a defensible choice for a team with the engineering capacity to run and patch them.
How should we think about rate limiting for partner-facing APIs specifically?
Partner and public APIs need tiered limits keyed to the consumer, not a single global ceiling, because a misbehaving integration should degrade gracefully for that one partner rather than throttle every consumer at once.
Do these platforms handle API versioning well?
Most support versioning through path or header-based routing, letting v1 and v2 of an endpoint run side by side while consumers migrate on their own schedule, and the better developer portals show which version each documented endpoint belongs to.
What does an AI gateway add that a regular API gateway does not?
An AI gateway, now offered as an add-on or built-in mode by several vendors in this list, applies the same rate-limiting and auth concepts to calls made to large language model providers, plus token-based cost metering, prompt or response logging for audit purposes, and semantic caching to cut repeat-query costs.
Can a small team realistically run a self-hosted gateway, or is that only for large platform teams?
A single platform engineer can run a self-hosted open-source gateway for a modest number of APIs, particularly with the container images and Helm charts most of these projects publish, but it is an ongoing operational responsibility: patching, capacity planning and on-call for a component now sitting in front of every API call.
How do open banking or open finance rules affect which vendor to pick?
Regulated markets running open banking or open finance mandates, including Brazil's framework, typically require specific consent-management flows, mutual TLS or FAPI-compliant auth, and audit logging beyond what a generic gateway ships by default.
