Ketchup is a very small HTTP server implementation, currently 300 LoC (for the whole thing)! Ketchup is also made to be as modular and embeddable as possible, if you want a cabal-free Haskell app, just take those two/three files you need and put it in your project! Currently Ketchup comes with: Basic httpd functionality (IPV4 only for now) URL Routing with parameters (ie. /user/:name/) Static file handler (ie. static "." as route/handler) Basic Auth (please use it over a HTTPS reverse proxy) Dependencies The core parts of Ketchup are all depedency free, that includes Ketchup.Httpd and Ketchup.Utils (and to a certain extent, Ketchup.Chunked). The dependencies required are for the following modules: Ketchup.Static (uses mime-types) Ketchup.Auth (uses base64-bytestring)
