NGINX
NGINX is a high-performance open-source web server, reverse proxy, and API gateway widely used for load balancing, SSL termination, caching, and traffic management for APIs and microservices. Originally written by Igor Sysoev and released under the 2-clause BSD license, NGINX powers a significant portion of the world's web traffic. Enterprise support and commercial features are available from F5, Inc.
NGINX publishes 28 APIs on the APIs.io network, including Connections API, General Info API, HTTP API, and 25 more. Tagged areas include API Gateway, Caching, Cloud Native, Load Balancer, and Open Source.
The NGINX catalog on APIs.io includes 2 JSON-LD contexts and 2 Spectral governance rulesets.
NGINX’s developer surface includes documentation, getting-started guide, engineering blog, changelog, support, YouTube channel, Stack Overflow tag, and 18 more developer resources.
