Zuplo vs KrakenD
As an alternative to KrakenD, developers choose Zuplo for full API lifecycle management — including a built-in developer portal, API key management, and monetization — all without self-hosting infrastructure or managing declarative JSON configuration files.
Why teams move away from KrakenD
Self-Hosted Only
KrakenD requires you to deploy, scale, and maintain your own infrastructure — there is no managed cloud offering
No Built-In Developer Portal
KrakenD has no developer portal for API documentation or self-serve API key management — you need separate tooling
Declarative Config Only
All gateway logic is defined in a single JSON configuration file with no support for custom code-based policies
Why choose Zuplo
Teams choose Zuplo over KrakenD when they need full API management without the operational overhead of self-hosting. Zuplo provides a built-in developer portal, API key management, programmable rate limiting, and API monetization out of the box — all deployed to 300+ edge locations globally without managing servers, containers, or configuration files.
Fully Managed Deployment
Fully managed edge deployment vs. KrakenD's self-hosted-only model requiring your own infrastructure.
Developer Portal
Built-in developer portal with self-serve API keys vs. no portal in KrakenD.
Programmable Policies
TypeScript-based programmable policies vs. KrakenD's declarative JSON config with Go plugins for custom logic.
API Key Management
Built-in API key management with self-serve portal vs. KrakenD's Enterprise-only API key auth with no key management UI.
API Monetization
Native API monetization with Stripe integration vs. no built-in monetization in KrakenD.
About KrakenD
KrakenD is an open-source, high-performance API gateway written in Go, designed for microservices architectures. Its stateless, database-free design enables linear horizontal scalability and high throughput. KrakenD processes all configuration from a single declarative JSON file at startup, making it fast and predictable. The project offers a free Community Edition and a commercial Enterprise Edition with additional features like API key authentication, tiered rate limiting, and Redis-backed global rate limits.
The Zuplo advantage
- Fully Managed Deployment
- Developer Portal
- Programmable Policies
- API Key Management
- API Monetization
Feature-by-feature comparison
| Feature | Zuplo | KrakenD |
|---|---|---|
| Fully Managed Deployment | Fully managed and serverless — deploys to 300+ edge data centers globally in under 20 seconds with no servers or containers to manage | Self-hosted only. You deploy, scale, and maintain KrakenD on your own infrastructure using Docker or Kubernetes |
| Developer Portal | Built-in developer portal auto-generated from OpenAPI specs with interactive API explorer, self-serve API key management, and custom branding | No developer portal. You need separate tooling like Swagger UI or a custom-built portal for API documentation |
| Programmable Policies | Write custom gateway logic in TypeScript with full access to the request and response lifecycle. Policies run natively on the edge | Declarative JSON configuration only. Custom logic requires Go plugins, Lua scripts, or Google CEL expressions |
| API Key Management | Built-in API key service with self-serve key creation, rotation, and revocation. Keys can store custom metadata for per-user policies | API key authentication is an Enterprise-only feature. No built-in key management portal — keys are defined in the gateway configuration file |
| API Monetization | API monetization with metering, usage-based billing, and plan management built into the gateway with Stripe and other billing integrations | No built-in monetization. Requires external billing integrations and custom development |
| Rate Limiting | Per-user, per-key, or per-IP rate limiting with TypeScript-based dynamic policies. Supports custom logic like tier-based limits using API key metadata | Multi-layer rate limiting at endpoint, backend, and service levels. Tiered rate limiting and Redis-backed global limits are Enterprise-only features |
| Authentication | Built-in API key management, JWT authentication, OpenID Connect, and support for multiple auth methods on a single route | Supports JWT validation (including tokens from OpenID Connect providers), OAuth2 client credentials, and mTLS. API key and basic auth are Enterprise-only features |
| Performance | Serverless edge deployment across 300+ global data centers for ultra-low latency worldwide. Auto-scales with no capacity planning | High-throughput Go architecture with stateless design for linear horizontal scalability. Benchmarks show strong single-node performance |
| API Aggregation | Route to multiple backends per endpoint with custom TypeScript logic for composing responses | Purpose-built for API aggregation. Parallel backend calls with response merging, filtering, and transformation are core features |
| GitOps Support | Gateway configuration stored in version-control-friendly files. GitHub integration creates preview environments per branch and syncs with CI/CD pipelines | Single JSON configuration file is version-control friendly. GitOps deployment requires custom CI/CD setup for rolling out config changes |
| OpenAPI Support | OpenAPI-native routing and configuration. Import specs to auto-generate routes, developer portal documentation, and request validation policies | OpenAPI import and export is an Enterprise-only feature. Community Edition does not integrate with OpenAPI specs |
| Protocol Support | HTTP/REST and WebSocket support with TypeScript handlers for custom protocol logic | Broad protocol support including REST, gRPC, GraphQL, WebSockets, SOAP, and message broker integrations like RabbitMQ and SQS |
Frequently Asked Questions
Common questions about Zuplo vs KrakenD.
Is Zuplo easier to set up than KrakenD?
Yes. KrakenD requires you to deploy and manage your own infrastructure — typically Docker containers or Kubernetes clusters — and configure the gateway through a JSON file. Zuplo is fully managed: you sign up, import an OpenAPI spec or create routes in the UI, and deploy to 300+ edge locations in seconds. There are no servers, containers, or config files to manage.
Does KrakenD have a developer portal?
No. KrakenD does not include a developer portal. If you need API documentation, an API explorer, or self-serve API key management for your consumers, you'll need to build or integrate separate tooling. Zuplo includes a developer portal in every plan, auto-generated from your OpenAPI spec with interactive documentation and self-serve API key management.
How does rate limiting compare between Zuplo and KrakenD?
KrakenD offers multi-layer rate limiting at the endpoint, backend, and service levels using token bucket algorithms. However, tiered rate limiting and Redis-backed global rate limits are Enterprise-only features. Zuplo provides programmable rate limiting with TypeScript, supporting dynamic per-user or per-tier limits using API key metadata — no external data stores required for distributed enforcement.
Is KrakenD really free?
KrakenD's Community Edition is free and open source, but it lacks features many teams need in production — including API key authentication, OpenAPI integration, tiered rate limiting, and basic auth. These are only available in the Enterprise Edition, which requires custom pricing. You also need to factor in the cost of hosting, scaling, and maintaining your own infrastructure.
Can Zuplo match KrakenD's performance?
KrakenD's Go-based architecture is optimized for high throughput on a single node. Zuplo takes a different approach: rather than maximizing single-node performance, it deploys your gateway to 300+ edge locations globally, so requests are handled close to your users with ultra-low latency. For most API use cases, Zuplo's edge architecture delivers better real-world performance than a centrally-hosted KrakenD instance.
Does Zuplo support API aggregation like KrakenD?
KrakenD excels at API aggregation — merging responses from multiple backends into a single endpoint is a core feature. Zuplo supports routing to multiple backends and composing responses with custom TypeScript logic, but KrakenD's declarative aggregation is more purpose-built for backend-for-frontend patterns. If API aggregation is your primary use case, KrakenD may be the better fit.
