Every Site on HTTPS
Caddy is a general-purpose HTTP/2 web server that serves HTTPS by default.
Download · Documentation · Community
Caddy is fast, easy to use, and makes you more productive.
Available for Windows, Mac, Linux, BSD, Solaris, and Android.
Menu
Features
- Easy configuration with the Caddyfile
- Automatic HTTPS on by default (via Let's Encrypt)
- HTTP/2 by default
- Virtual hosting so multiple sites just work
- Experimental QUIC support for those that like speed
- TLS session ticket key rotation for more secure connections
- Extensible with plugins because a convenient web server is a helpful one
- Runs anywhere with no external dependencies (not even libc)
There's way more, too! See all features built into Caddy. On top of all those, Caddy does even more with plugins: choose which plugins you want at download.
Install
Caddy binaries have no dependencies and are available for every platform. Get Caddy any one of these ways:
- Download page allows you to customize your build in the browser
- Latest release for pre-built, vanilla binaries
- go get to build from source:
go get github.com/mholt/caddy/caddy(requires Go 1.8 or newer)
Then make sure the caddy binary is in your PATH.
Quick Start
To serve static files from the current working directory, run:
caddy
Caddy's default port is 2015, so open your browser to http://localhost:2015.
Go from 0 to HTTPS in 5 seconds
If the caddy binary has permission to bind to low ports and your domain name's DNS records point to the machine you're on:
caddy -host example.com
This command serves static files from the current directory over HTTPS. Certificates are automatically obtained and renewed for you!
Customizing your site
To customize how your site is served, create a file named Caddyfile by your site and paste this into it:
localhost
push
browse
websocket /echo cat
ext .html
log /var/log/access.log
proxy /api 127.0.0.1:7005
header /api Access-Control-Allow-Origin *
When you run caddy in that directory, it will automatically find and use that Caddyfile.
This simple file enables server push (via Link headers), allows directory browsing (for folders without an index file), hosts a WebSocket echo server at /echo, serves clean URLs, logs requests to an access log, proxies all API requests to a backend on port 7005, and adds the coveted Access-Control-Allow-Origin: * header for all responses from the API.
Wow! Caddy can do a lot with just a few lines.
Doing more with Caddy
To host multiple sites and do more with the Caddyfile, please see the Caddyfile tutorial.
Sites with qualifying hostnames are served over HTTPS by default.
Caddy has a command line interface. Run caddy -h to view basic help or see the CLI documentation for details.
Running in Production
Caddy is production-ready if you find it to be a good fit for your site and workflow.
Running as root: We advise against this. You can still listen on ports < 1024 on Linux using setcap like so: sudo setcap cap_net_bind_service=+ep ./caddy
The Caddy project does not officially maintain any system-specific integrations nor suggest how to administer your own system. But your download file includes unofficial resources contributed by the community that you may find helpful for running Caddy in production.
How you choose to run Caddy is up to you. Many users are satisfied with nohup caddy &. Others use screen. Users who need Caddy to come back up after reboots either do so in the script that caused the reboot, add a command to an init script, or configure a service with their OS.
If you have questions or concerns about Caddy' underlying crypto implementations, consult Go's crypto packages, starting with their documentation, then issues, then the code itself; as Caddy uses mainly those libraries.

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.
The name "Caddy": The name of the software is "Caddy", not "Caddy Server" or "CaddyServer". Please call it "Caddy" or, if you wish to clarify, "the Caddy web server". See brand guidelines.
