I believe the most complete solution is a full unix environment with shell piping the image stream. so i make https://bash.rocks https://bash.rocks, which is a web frontend backed by a unix environment. Snippets: 1. Resizing with imagemagick: https://bash.rocks/Gxlg31/3 https://bash.rocks/Gxlg31/3 2. Resizing and convert to webp: https://bash.rocks/7J1jgB/1 https://bash.rocks/7J1jgB/1 After creating the snippet, you could either use GET https://bash.rocks/0Be95B https://bash.rocks/0Be95B (query parameters become environment variable) or POST https://bash.rocks/jJggWJ https://bash.rocks/jJggWJ (request body become stdin). It's not hard to roll your backend like this for private usage (simply exec from node). I'm also working on an open source release.
