    Start apps from your browser and use local domains/https automatically

    Tip: if you don't enable local domains, hotel can still be used as a catalog of local servers.

    Hotel works great on any OS (OS X, Linux, Windows) and with all servers ❤️

    • Node (Express, Webpack)
    • PHP (Laravel, Symfony)
    • Ruby (Rails, Sinatra, Jekyll)
    • Python (Django)
    • Docker
    • Go
    • Apache, Nginx
    • ...

    v0.8.0 upgrade

    .localhost replaces .dev local domain and is the new default. See for context.

    If you're upgrading, please be sure to:

    1. Remove "tld": "dev" from your ~/.hotel/conf.json file
    2. Run hotel stop && hotel start
    3. Refresh your network settings


    If you are benefiting from hotel and would like to help keep them sustainable, you can support its development on Patreon.



    • Local domains - http://project.localhost
    • HTTPS via local self-signed SSL certificate - https://project.localhost
    • Wildcard subdomains - http://*.project.localhost
    • Works everywhere - OS X, Linux and Windows
    • Works with any server - Node, Ruby, PHP, ...
    • Proxy - Map local domains to remote servers
    • System-friendly - No messing with port 80, /etc/hosts, sudo or additional software
    • Fallback URL - http://localhost:2000/project
    • Servers are only started when you access them
    • Plays nice with other servers (Apache, Nginx, ...)
    • Random or fixed ports


    npm install -g hotel && hotel start

    Hotel requires Node to be installed, if you don't have it, you can simply install it using one of the following method:

    Quick start

    Local domains (optional)

    To use local .localhost domains, you need to configure your network or browser to use hotel's proxy auto-config file or you can skip this step for the moment and go directly to http://localhost:2000

    See instructions here.

    Add your servers

    # Add your server to hotel 
    ~/projects/one$ hotel add 'npm start'
    # Or start your server in the terminal as usual and get a temporary local domain 
    ~/projects/two$ hotel run 'npm start' 

    Visit localhost:2000 or http(s)://hotel.localhost.

    Alternatively you can directly go to


    Popular servers examples

    Using other servers? Here are some examples to get you started :)

    hotel add 'ember server'                               # Ember 
    hotel add 'jekyll serve --port $PORT'                  # Jekyll 
    hotel add 'rails server -p $PORT -b'         # Rails 
    hotel add 'python -m SimpleHTTPServer $PORT'           # static file server (Python) 
    hotel add 'php -S$PORT'                     # PHP 
    hotel add 'docker-compose up'                          # docker-compose 
    hotel add 'python runserver$PORT' # Django 
    # ... 

    On Windows use "%PORT%" instead of '$PORT'

    See a Docker example here..

    Proxy requests to remote servers

    Add your remote servers

    ~$ hotel add --name aliased-address
    ~$ hotel add --name aliased-domain 

    You can now access them using

    http://aliased-address.localhost # will proxy requests to 
    http://aliased-domain.localhost # will proxy requests to 

    CLI usage and options

    hotel add <cmd|url> [opts]
    hotel run <cmd> [opts]
    # Examples 
    hotel add 'nodemon app.js' --out dev.log  # Set output file (default: none) 
    hotel add 'nodemon app.js' --name name    # Set custom name (default: current dir name) 
    hotel add 'nodemon app.js' --port 3000    # Set a fixed port (default: random port) 
    hotel add 'nodemon app.js' --env PATH     # Store PATH environment variable in server config 
    hotel add --name app  # map local domain to URL 
    hotel run 'nodemon app.js'                # Run server and get a temporary local domain 
    # Other commands 
    hotel ls     # List servers 
    hotel rm     # Remove server 
    hotel start  # Start hotel daemon 
    hotel stop   # Stop hotel daemon 

    To get help

    hotel --help
    hotel --help <cmd>


    For hotel to work, your servers need to listen on the PORT environment variable. Here are some examples showing how you can do it from your code or the command-line:

    var port = process.env.PORT || 3000
    hotel add 'cmd -p $PORT'  # OS X, Linux 
    hotel add "cmd -p %PORT%" # Windows 

    Fallback URL

    If you're offline or can't configure your browser to use .localhost domains, you can always access your local servers by going to localhost:2000.

    Configurations, logs and self-signed SSL certificate

    You can find hotel related files in ~/.hotel :


    By default, hotel uses the following configuration values:

      "port": 2000,
      "host": '',
      // Timeout when proxying requests to local domains
      "timeout": 5000,
      // Change this if you want to use another tld than .localhost
      "tld": 'localhost', 
      // If you're behind a corporate proxy, replace this with your network proxy IP (example: "")
      "proxy": false

    To override a value, simply add it to ~/.hotel/conf.json and run hotel stop && hotel start

    Third-party tools


    Seting a fixed port

    hotel add --port 3000 'server-cmd $PORT' 

    Adding X-Forwarded-* headers to requests

    hotel add --xfwd 'server-cmd'

    Setting HTTP_PROXY env

    Use --http-proxy-env flag when adding your server or edit your server configuration in ~/.hotel/servers

    hotel add --http-proxy-env 'server-cmd'

    Proxying requests to a remote https server

    hotel add --change-origin ''

    When proxying to a https server, you may get an error because your .localhost domain doesn't match the host defined in the server certificate. With this flag, host header is changed to match the target URL.

    ENOSPC and EACCES errors

    If you're seeing one of these errors in ~/.hotel/daemon.log, this usually means that there's some permissions issues. hotel daemon should be started without sudo and ~/.hotel should belong to $USER.

    # to fix permissions 
    sudo chown -R $USER$HOME/.hotel

    Configuring a network proxy IP

    If you're behind a corporate proxy, replace "proxy" with your network proxy IP in ~/.hotel/conf.json. For example:

      "proxy": ""
