Caddy is a lightweight, general-purpose web server for Windows, Mac, Linux, BSD, and [Android](https://github.com/mholt/caddy/wiki/Running-Caddy-on-Android). It is a capable alternative to other popular and easy to use web servers.
|
|
|
|
The most notable features are HTTP/2, [Let's Encrypt](https://letsencrypt.org) support, Virtual Hosts, TLS + SNI, and easy configuration with a [Caddyfile](https://caddyserver.com/docs/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.

## Getting Caddy
|
|
|
|
Caddy binaries have no dependencies and are available for nearly every platform.
|
|
|
|
[Latest release](https://github.com/mholt/caddy/releases/latest)
|
|
|
|
|
|
|
|
## Quick Start
|
|
|
|
The website has [full documentation](https://caddyserver.com/docs) 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.
|
|
|
|

## Running from Source
|
|
|
|
Note: You will need **[Go 1.4](https://golang.org/dl)** or newer
|
|
|
|
1. `$ go get github.com/mholt/caddy`
|
|
2. `cd` into your website's directory
|
|
3. Run `caddy` (assumes `$GOPATH/bin` is in your `$PATH`)
|
|
|
|
If you're tinkering, you can also use `go run main.go`.
|
|
|
|
By default, Caddy serves the current directory at [localhost:2015](http://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 < 1024 like 80 and 443.
|
|
|
|
|
|
|
|
#### Docker Container
|
|
|
|
Caddy is available as a Docker container from any of these sources:
|
|
|
|
- [abiosoft/caddy](https://registry.hub.docker.com/u/abiosoft/caddy/)
|
|
- [darron/caddy](https://registry.hub.docker.com/u/darron/caddy/)
|
|
- [joshix/caddy](https://registry.hub.docker.com/u/joshix/caddy/)
|
|
- [jumanjiman/caddy](https://registry.hub.docker.com/u/jumanjiman/caddy/)
|
|
- [zenithar/nano-caddy](https://registry.hub.docker.com/u/zenithar/nano-caddy/)
|
|
|
|
|
|
|
|
#### 3rd-party dependencies
|
|
|
|
Although Caddy's binaries are completely static, Caddy relies on some excellent libraries. [Godoc.org](https://godoc.org/github.com/mholt/caddy) 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](https://github.com/rif/spark), nginx, lighttpd, Websocketd, and Vagrant, and provides a pleasant mixture of features from each of them.
