AWS API Gateway vs. Tyk

AWS API Gateway eliminates infrastructure management entirely. You configure APIs through the AWS console or CLI, and AWS handles scaling, patching, and availability. The trade-off is significant: no plugin system, no developer portal, limited protocol support, and all custom logic must be implemented through Lambda functions — adding cold-start latency and per-invocation costs.

Tyk provides a full API management platform that you self-host. It includes a developer portal, API analytics, monetization, and versioning out of the box. However, Tyk requires Redis and MongoDB/PostgreSQL for operation, adding operational complexity. Performance is moderate at ~6,900 RPS — sufficient for many workloads but limiting for high-throughput scenarios.

Apache APISIX offers the operational simplicity of a lightweight deployment (NGINX + etcd, no heavy database) with richer API management capabilities than AWS and higher performance than Tyk. Configuration syncs in milliseconds through etcd watch, each node runs statelessly, and 100+ plugins are available without an enterprise paywall.

AWS API Gateway has a default limit of 10,000 requests per second per region. Lambda-backed APIs add cold-start delays of 100ms to 1 second. While limits can be increased through support requests, the managed proxy layer always introduces baseline latency that self-hosted gateways avoid.

Tyk handles approximately 6,900 requests per second with an introduced latency of about 8.6 milliseconds at the 95th percentile. Its Go-based architecture is memory-efficient but delivers lower throughput than NGINX-based gateways. Scaling requires additional gateway instances connected to shared Redis and database infrastructure.

Apache APISIX achieves 23,000 QPS per core with 0.2ms average latency — approximately 3x Tyk's throughput and far exceeding AWS API Gateway's default limits. In published benchmarks, APISIX consistently delivers the highest throughput among open-source API gateways, with configuration updates propagating in milliseconds through etcd watch.

AWS API Gateway provides basic API management: request routing, throttling, and stage-based deployment (dev/staging/prod). But it lacks a developer portal, API analytics beyond CloudWatch metrics, request/response transformation capabilities, and API monetization. Teams needing full lifecycle management must combine AWS API Gateway with additional AWS services and custom development.

Tyk is the strongest in this category among the three, offering a complete API management platform: built-in developer portal with customizable branding, API analytics and usage tracking, API monetization, GraphQL support including Federation, and API versioning. This makes Tyk a compelling choice for teams that prioritize API lifecycle management over raw performance.

Apache APISIX provides rich API management through API7 Enterprise: developer portal with documentation and monetization, advanced rate limiting, canary releases, traffic splitting, and request transformation. Combined with 3x Tyk's throughput and 100+ open-source plugins, APISIX delivers API management depth without sacrificing performance.

AWS API Gateway charges $1.00 per million REST API calls with no volume discounts. At 100 million daily API calls, the gateway alone costs ~$3,000/month — before Lambda execution costs, data transfer, and CloudWatch logging. Organizations with high-throughput APIs frequently find AWS API Gateway is their largest single AWS line item.

Tyk offers a free Community Edition with limited features. The Pro tier adds the developer portal, analytics, and multi-data-center support. Enterprise pricing is custom and typically includes per- gateway-instance licensing. Infrastructure costs (compute, Redis, database) are additional. The total cost of ownership can be significant for large deployments.

API7 Enterprise uses CPU-core-based pricing, meaning costs scale predictably with your infrastructure rather than per API call. The open-source APISIX includes all 100+ plugins without an enterprise paywall, so organizations avoid the hidden cost of upgrading tiers to unlock security, observability, or rate-limiting features. This makes APISIX the most cost-effective option at virtually any scale.

AWS API Gateway creates the deepest lock-in. API configurations, Lambda authorizers, IAM policies, and VTL mapping templates are all AWS-specific. Migrating to any other gateway requires rewriting every integration point. There is no open-source component and no portability path.

Tyk's open-source gateway is licensed under MPL 2.0 (Mozilla Public License), which is more restrictive than Apache 2.0 — it requires modifications to Tyk source code to be published under the same license. The developer portal and advanced analytics require commercial licensing from Tyk Technologies. The project is primarily developed by Tyk Technologies, a single commercial entity.

Apache APISIX has the lowest vendor lock-in risk. Licensed under Apache 2.0 and governed by the Apache Software Foundation, no single company controls the project. All 100+ plugins and the complete codebase are open source. API7.ai is the commercial company behind APISIX, offering API7 Enterprise with professional support while preserving full infrastructure portability and community governance.
