Static file server written in Crystal.


alive is a fast, secure, efficient and easy to use static file server. It can both be used as a library and a CLI program. The purpose of alive is to make static website development faster and without a hassle. It follows the Unix philosophy, "do one thing and do it well". Out of the box, alive allows you to customize every option it has.

Reasons to use alive

  • Secure by default.
  • Both HTTP and HTTPS support.
  • Lightweight and well-documented code.
  • Easily portable and customizable.
  • Performant.

CLI usage

  1. Clone the repository like so: git clone
  2. Enter the directory: cd alive
  3. Build using: crystal build -o alive --release
  4. Run the program like so: ./alive
  5. This will start a static file server with all the default options set.
  6. You can of course customize how the server will behave using program arguments. It is optional, but you may want to look at what features it offers. To do that simply run ./alive -h or ./alive --help
  7. Here's an example of what the output would look like:
Usage: ./alive [arguments (optional)]
    -h, --help                       Displays helpful information.
    -d <path>, --directory=<path>    Set the directory path to serve files from. Default: .
    -a <address>, --address=<address>
                                     Address to listen on. Default: random (127.0.0.x)
    -p <port>, --port=<port>         Port to listen on. Default: random (1-65535)
    -t, --tls                        Enable TLS. Default: false
    -k <path>, --key=<path>          Set the private key path. Default: private.key
    -c <path>, --certificate=<path>  Set the certificate chain path. Default: certificate.crt
    -l, --directory-listing         Disable directory listing. Default: true

Library usage

  1. Add the dependency to your shard.yml:
        github: often/alive
  1. Run shards install
  2. That's it. You may now use it like so:
require "alive"

alive # Starts a static file server with all the default options set.
alive tls: true, key: "/path/to/private.key", certificate: "/path/to/certificate.crt" # Starts a static file server with TLS enabled.
alive directory_listing: false # Starts a static file server with directory listing disabled.
# and so on.


If it is a public website you are hosting with alive I recommend that you enable TLS. You can get a free TLS certificate from Let's Encrypt. You may also generate a self-signed TLS certificate if it is a local development server you are running. For additional security steps you might want to disable directory listing. After building you may want to setup an alias in your .bashrc for ease of access. I did it like so: alias alive="/path/to/alive"
