These changes span work from the last ~4 months in an effort to make Caddy more extensible, reduce the coupling between its components, and lay a more robust foundation of code going forward into 1.0. A bunch of new features have been added, too, with even higher future potential. The most significant design change is an overall inversion of dependencies. Instead of the caddy package knowing about the server and the notion of middleware and config, the caddy package exposes an interface that other components plug into. This does introduce more indirection when reading the code, but every piece is very modular and pluggable. Even the HTTP server is pluggable. The caddy package has been moved to the top level, and main has been pushed into a subfolder called caddy. The actual logic of the main file has been pushed even further into caddy/caddymain/run.go so that custom builds of Caddy can be 'go get'able. The HTTPS logic was surgically separated into two parts to divide the TLS-specific code and the HTTPS-specific code. The caddytls package can now be used by any type of server that needs TLS, not just HTTP. I also added the ability to customize nearly every aspect of TLS at the site level rather than all sites sharing the same TLS configuration. Not all of this flexibility is exposed in the Caddyfile yet, but it may be in the future. Caddy can also generate self-signed certificates in memory for the convenience of a developer working on localhost who wants HTTPS. And Caddy now supports the DNS challenge, assuming at least one DNS provider is plugged in. Dozens, if not hundreds, of other minor changes swept through the code base as I literally started from an empty main function, copying over functions or files as needed, then adjusting them to fit in the new design. Most tests have been restored and adapted to the new API, but more work is needed there. A lot of what was "impossible" before is now possible, or can be made possible with minimal disruption of the code. For example, it's fairly easy to make plugins hook into another part of the code via callbacks. Plugins can do more than just be directives; we now have plugins that customize how the Caddyfile is loaded (useful when you need to get your configuration from a remote store). Site addresses no longer need be just a host and port. They can have a path, allowing you to scope a configuration to a specific path. There is no inheretance, however; each site configuration is distinct. Thanks to amazing work by Lucas Clemente, this commit adds experimental QUIC support. Turn it on using the -quic flag; your browser may have to be configured to enable it. Almost everything is here, but you will notice that most of the middle- ware are missing. After those are transferred over, we'll be ready for beta tests. I'm very excited to get this out. Thanks for everyone's help and patience these last few months. I hope you like it!! |

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. (@caddyserver on Twitter)
The most notable features are HTTP/2, Let's Encrypt support, Virtual Hosts, TLS + SNI, and easy configuration with a Caddyfile. In development, you usually put one Caddyfile with each site. In production, Caddy serves HTTPS by default and manages all cryptographic assets for you.
Menu
Getting Caddy
Caddy binaries have no dependencies and are available for nearly every platform.
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 a WebSocket echo server at
/echo, logs requests 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:
site1.com {
# ...
}
site2.com, sub.site2.com {
# ...
}
Note that all these sites will automatically be served over HTTPS using Let's Encrypt as the CA. Caddy will manage the certificates (including renewals) for you. You don't even have to think about it.
For more documentation, please view the website. You may also be interested in the [developer guide] (https://github.com/mholt/caddy/wiki) on this project's GitHub wiki.
Running from Source
Note: You will need Go 1.6 or newer (required for transparent automatic HTTP/2 support and to take advantage of performance improvements in the TLS and crypto libraries).
$ 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 ./build.bash && ./ecaddy.
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 or see the CLI documentation.
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 < 1024 like 80 and 443.
Docker Container
Caddy is available as a Docker container from any of these sources:
3rd-party dependencies
Although Caddy's binaries are completely static, Caddy relies on some excellent libraries. Godoc.org shows the packages that each Caddy package imports.

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, which provides a pleasant mixture of features from each of them.
