Caddy is a lightweight, general-purpose web server for Windows, Mac, Linux, BSD, and Android. It is a capable alternative to other popular and easy to use web servers.
The most notable features are HTTP/2, Virtual Hosts, TLS + SNI, and easy configuration with a Caddyfile. Usually, you have one Caddyfile per site. Most directives for the Caddyfile invoke a layer of middleware which can be used in your own Go programs.
Menu
Getting Caddy
Caddy binaries have no dependencies and are available for nearly every platform.
Running from Source
Note: You will need Go 1.4 or newer
$ go get github.com/mholt/caddycdinto your website's directory- Run
caddy(assumes$GOPATH/binis in your$PATH)
If you're tinkering, you can also use go run main.go.
By default, Caddy serves the current directory at localhost:2015. You can place a Caddyfile to configure Caddy for serving your site.
Caddy accepts some flags from the command line. Run caddy -h to view the help for flags. You can also pipe a Caddyfile into the caddy command.
Running as root: We advise against this; use setcap instead, like so: setcap cap_net_bind_service=+ep ./caddy This will allow you to listen on ports below 1024 (like 80 and 443).
Docker Container
Caddy is available as a Docker container from any of these sources:
3rd-party libraries
Although Caddy's binaries are completely static, Caddy relies on some excellent libraries. Godoc.org shows the packages that each Caddy package imports.
Quick Start
The website has full documentation but this will get you started in about 30 seconds:
Place a file named "Caddyfile" with your site. Paste this into it and save:
localhost
gzip
browse
ext .html
websocket /echo cat
log ../access.log
header /api Access-Control-Allow-Origin *
Run caddy from that directory, and it will automatically use that Caddyfile to configure itself.
That simple file enables compression, allows directory browsing (for folders without an index file), serves clean URLs, hosts an echo server for WebSocket connections at /echo, logs accesses to access.log, and adds the coveted Access-Control-Allow-Origin: * header for all responses from some API.
Wow! Caddy can do a lot with just a few lines.
Defining multiple sites
You can run multiple sites from the same Caddyfile, too:
http://mysite.com,
http://www.mysite.com {
redir https://mysite.com
}
https://mysite.com {
tls mysite.crt mysite.key
# ...
}
Note that the secure host will automatically be served with HTTP/2 if the client supports it.
For more documentation, please view the website. You may also be interested in the developer guide on this project's GitHub wiki.

This project would not be what it is without your help. Please see the contributing guidelines if you haven't already.
Thanks for making Caddy -- and the Web -- better!
Special thanks to 
for hosting the Caddy project.
About the project
Caddy was born out of the need for a "batteries-included" web server that runs anywhere and doesn't have to take its configuration with it. Caddy took inspiration from spark, nginx, lighttpd, Websocketd, and Vagrant, and provides a pleasant mixture of features from each of them.
