It was originally sponsored by Taobao before 2011 and was mainly supported by Cloudflare from 2012 to 2016. Since 2017, it has been mainly supported by OpenResty Software Foundation and OpenResty Inc.

OpenResty is designed to build scalable web applications, web services, and dynamic web gateways. The OpenResty architecture is based on several nginx modules which have been extended in order to expand nginx into a web app server to handle large number of requests.{{cite web | last=Tourne | first=Matthieu | date=2012-12-08 | url=https://blog.cloudflare.com/pushing-nginx-to-its-limit-with-lua/ | title=Pushing Nginx to its limit with Lua | website=The Cloudflare Blog | publisher=Cloudflare | access-date=2022-02-05}} OpenResty aims to run Lua server-side applications completely in the Nginx server, leveraging its event model to do non-blocking I/O not only for client connections, but also with remote resources, such as databases.
