Hosting wsrv.nl on your own server

The image service is free for use to anyone, and we offer it as-is, it's just basic image resizing, available to anyone, easy to use. We try to keep everyone as happy as we can.

If you're however interested in running the source code yourself, and use the service internally, the source code is hosted here:

https://github.com/weserv/images

The entire codebase has been written in C++ as an nginx module since API 5. Earlier versions used different technologies:

• API 4 was built with LuaJIT and OpenResty.
• API 3 was built with PHP.
