KrakenD API Gateway (.5k)

Serves over 70K requests per second on a single instance with low memory consumption (under 50MB with high traffic), as highlighted in the README, ensuring cost-effective scaling.

Operates as a stateless gateway enabling true linear scalability in clusters without coordination, per the README's emphasis on independent node operation for no single point of failure.

Includes zero-trust policy, OAuth, JWT, CORS, HSTS, and multi-layer rate limiting with circuit breaker, providing robust security out-of-the-box.

Supports Go plugins, Lua scripts, Martian, and Google CEL spec for custom functionality, allowing deep customization and integration with existing tools.
