Alternatives to KrakenD
High-performance, stateless open-source API gateway.
KrakenD ranks #6 of 8 in API gateways, with an Alt Score of 86. It is licensed under Apache-2.0, open source with paid hosting from Free and available on Linux and Web. 13 of 13 checklist rows are verified against a public source.
KrakenD is a high-performance, stateless open-source API gateway that aggregates and transforms backend services through declarative configuration.
Platform and backend engineering teams building microservices or Backend-for-Frontend architectures who need a stateless, high-performance API gateway they run themselves — from startups running the free Community Edition to regulated enterprises (banking, government, e-commerce) that need SLA-backed support, RBAC/security policies, and audited GitOps deployments on the paid Enterprise Edition.
A single Go binary / Docker image that acts as an API gateway and Backend-for-Frontend: it aggregates, transforms, and filters calls to REST, gRPC, GraphQL, SOAP, Kafka, RabbitMQ, and Lambda backends, and adds JWT/OAuth2 authentication, rate limiting, circuit breaking, and OpenTelemetry-based observability, all driven by a declarative JSON/YAML configuration file. The Enterprise Edition adds 30+ extras such as a Security Policies engine (CEL-based RBAC/ABAC), Redis-backed stateful rate limiting, an AI Gateway (LLM routing, MCP server), and 24/7 SLA support.
You write (or auto-generate with the browser-based Designer) a krakend.json configuration describing endpoints and the backends they aggregate, then run the krakend binary or container, which loads that config at startup with no external database or coordination needed. Because it is stateless and immutable, you version the config in Git and roll it out via CI/CD (GitOps); there is no managed/hosted KrakenD service, so you deploy the binary yourself on Linux, Docker, or Kubernetes.
