This guide compares their **open-source gateway cores** and identifies where management, support, or hosted deployment has a separate commercial boundary. It does not compare enterprise contracts or claim a universal performance winner. If you are choosing among managed services and commercial platforms as well, use the broader [11-platform API gateway comparison](https://api7.ai/top-11-api-gateways-platforms-compared). For a primer on the gateway's role, start with [what an API gateway does](https://api7.ai/learning-center/api-gateway-guide/what-is-an-api-gateway). The product descriptions and licensing boundaries below were checked against vendor documentation on November 6, 2026. Features and packaging can change; verify the version and edition you intend to deploy. | Gateway core | Configuration and deployment choice | Open-source boundary | Evaluate it when | | ------------------------- | ---------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------- | | Apache APISIX | etcd-backed traditional or decoupled mode; standalone file-driven mode is also available | Apache APISIX is open source; API7 Enterprise support and management are separate | You need dynamic traffic policies and want to choose between a shared configuration store and a standalone configuration source. | | Kong Gateway OSS | PostgreSQL-backed traditional mode or DB-less declarative configuration | OSS gateway is distinct from Kong Gateway Enterprise and Konnect | You want Kong's gateway and plugin model and can choose a configuration mode that fits your plugins. | | Traefik Proxy | Dynamic configuration from providers such as Kubernetes, Docker, or files | Open-source proxy is distinct from wider commercial Traefik offerings | You want provider-driven service discovery and routing, particularly in container environments. | | KrakenD Community Edition | Declarative JSON configuration without a gateway database | Community Edition is distinct from KrakenD Enterprise | You need stateless API aggregation and response composition with a configuration-driven deployment. | | Tyk Gateway OSS | Self-hosted open-source gateway; management options depend on deployment | Dashboard and Developer Portal are separately licensed components | You need the open-source gateway and will explicitly assess whether paid management tooling is required. | These are selection starting points, not feature or throughput benchmarks. Check the specific release, plugins, operational topology, and licensing terms for your workload. Official references are linked in each profile below. ### Compare the Open-Source Cores by Capability | Capability to evaluate | Apache APISIX | Kong Gateway OSS | Traefik Proxy | KrakenD Community Edition | Tyk Gateway OSS | | ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Traffic model | Routes, upstreams, and configured plugins | Services, Routes, and configured plugins | Routers, services, and providers | Endpoints composed from backend services | API definitions, targets, and policies | | Access and rate limits | Configured [key-auth](https://apisix.apache.org/docs/apisix/plugins/key-auth/) and [limit-count](https://apisix.apache.org/docs/apisix/plugins/limit-count/) plugins are examples | [Key Auth](https://developer.konghq.com/plugins/key-auth/) and [Rate Limiting](https://developer.konghq.com/plugins/rate-limiting/) plugins are examples; check the selected topology | [BasicAuth](https://doc.traefik.io/traefik/master/reference/routing-configuration/http/middlewares/overview/) and [RateLimit](https://doc.traefik.io/traefik/reference/routing-configuration/http/middlewares/ratelimit/) are middleware examples, not a complete consumer-management system | [Community middleware](https://www.krakend.io/docs/overview/) includes OAuth2 authorization and rate limiting; confirm the required configuration | [Community Edition Gateway rate limits](https://tyk.io/docs/5.4/basic-config-and-security/control-limit-traffic/rate-limiting/) can be configured without assuming the paid Dashboard | | Metrics example | [Prometheus plugin](https://apisix.apache.org/docs/apisix/plugins/prometheus/) | [Prometheus plugin](https://developer.konghq.com/plugins/prometheus/) | Configurable [Prometheus or OpenTelemetry metrics](https://doc.traefik.io/traefik/reference/install-configuration/observability/metrics/) | [OpenTelemetry with a Prometheus exporter](https://www.krakend.io/docs/v2.10/telemetry/prometheus/); check the deployed release | [Tyk Pump](https://tyk.io/docs/4.3/tyk-stack/tyk-pump/other-data-stores/monitor-apis-prometheus/) can expose Prometheus metrics and is a separate component | This matrix identifies **where to verify a requirement**, not feature parity: an authentication method, telemetry exporter, or policy may depend on a specific release, plugin, external service, or commercial edition. Validate the exact feature in each vendor's linked documentation before shortlisting. ## Apache APISIX: Choose a Configuration Mode [Apache APISIX](https://apisix.apache.org/docs/apisix/architecture-design/apisix/) is built on NGINX and LuaJIT. Its core matches routes and selects upstreams; configured plugins can apply authentication, traffic control, observability, or transformations. Plugins do not automatically act on every request. Traditional and decoupled deployments use etcd for configuration. [Standalone file-driven mode](https://apisix.apache.org/docs/apisix/deployment-modes/) loads a full YAML or JSON configuration without etcd as the configuration center. Those modes have different update and operations paths, so saying APISIX *always* requires etcd would be inaccurate. Lua plugins run in-process, while external plugin runners support selected additional languages; the Wasm plugin runtime remains experimental in the [architecture documentation](https://apisix.apache.org/docs/apisix/architecture-design/apisix/). Choose APISIX when its routing and plugin model match your traffic requirements and you can operate the selected configuration mode. If you already run APISIX and need deployment, upgrade, or architecture assistance, [commercial support for existing APISIX deployments](https://api7.ai/apache-apisix-enterprise-support) is a separate decision from choosing the open-source gateway. ## Kong: Separate Gateway Modes From Konnect [Kong Gateway OSS](https://developer.konghq.com/gateway/upgrade/migrate-oss-to-ee/) supports traditional and DB-less deployments. A traditional deployment uses PostgreSQL; a DB-less gateway stores declarative configuration in memory and does not require a database. DB-less mode has limitations for plugins that require a database. Hybrid mode, which separates the control plane and data plane, is available with Kong Gateway Enterprise or Konnect, not the OSS core. Cassandra is not a current option: [Kong's upgrade guide](https://developer.konghq.com/gateway/upgrade/lts-upgrade-28-34/) says support was removed starting with Gateway 3.4. The [open-source gateway](https://github.com/Kong/kong/blob/master/LICENSE) and commercial Kong Gateway Enterprise or Konnect should not be treated as identical feature sets. Choose a topology and list the plugins you actually need before comparing operating effort or license costs. ## Traefik: Provider-Driven Routing [Traefik Proxy](https://doc.traefik.io/traefik/master/) is an open-source application proxy used with Kubernetes and other environments. Its [providers](https://doc.traefik.io/traefik/reference/install-configuration/providers/overview/) can supply routing configuration from Kubernetes resources, Docker labels, files, and other sources. File configuration is one option, not Traefik's only or defining configuration model. Traefik is worth evaluating when infrastructure-driven discovery and routing are central requirements. Before assuming equivalence with an API management platform, check the exact authentication, developer-portal, governance, and support features available in the edition you plan to use. ## KrakenD: Aggregation With Declarative Configuration [KrakenD Community Edition](https://www.krakend.io/open-source/) is an Apache-licensed, self-hosted gateway. Its [Community documentation](https://www.krakend.io/docs/overview/introduction/) emphasizes defining endpoints that aggregate and transform responses from backend services using declarative configuration. This can fit client-facing aggregation without introducing a gateway database. [KrakenD Enterprise](https://www.krakend.io/docs/enterprise/overview/introduction/) adds capabilities beyond Community Edition. Assess the edition needed for your authentication, telemetry, and operational requirements instead of assuming that every advertised KrakenD feature is available in the open-source build. ## Tyk: Gateway Versus Management Platform Tyk offers an open-source Gateway and a broader commercial API management platform. Its [deployment and licensing documentation](https://tyk.io/docs/deployment-options/tyk-hybrid/) separates the open-source Gateway and Pump from licensed components such as Dashboard and Developer Portal. Tyk Hybrid is a paid deployment option with a Tyk-hosted control plane, not a capability bundled with the stand-alone open-source Gateway. Evaluate Tyk Gateway for the traffic policies you need; evaluate the commercial platform separately if a graphical Dashboard, Developer Portal, managed control plane, or contractual support is required. Do not infer those capabilities from the Gateway's open-source license. ## How to Make the Choice 1. **Define the traffic boundary.** Is the main need API policy, container ingress, response aggregation, or full API lifecycle management? 2. **Choose a configuration source.** Compare etcd-backed and standalone APISIX, PostgreSQL-backed and DB-less Kong, provider-driven Traefik, and declarative KrakenD; document any operational dependencies. 3. **Check the edition.** Mark each required plugin, management UI, portal, analytics capability, and support commitment as included in the open-source core, a separate commercial feature, or not verified. 4. **Test one real workload.** Measure your own request mix, policy behavior, failure recovery, upgrade process, and observability. Vendor-level performance labels are not substitutes for a reproducible test. For a wider vendor shortlist that includes commercial deployment options, continue with the [11-platform API gateway comparison](https://api7.ai/top-11-api-gateways-platforms-compared). If Apache APISIX is already your chosen runtime, compare self-operation with [API7 Enterprise](https://api7.ai/api7-enterprise-vs-apisix) or get [support for an existing APISIX deployment](https://api7.ai/apache-apisix-enterprise-support).
