About YOURLSback to top

What is YOURLS

YOURLS stands for Your Own URL Shortener. It is a small set of PHP scripts that will allow you to run your own URL shortening service (a la TinyURL or bitly).

Running your own URL shortener is fun, geeky and useful: you own your data and don't depend on third party services. It's also a great way to add branding to your short URLs, instead of using the same public URL shortener everyone uses.

YOURLS Features

  • Free and Open Source software.
  • Private (your links only) or Public (everybody can create short links, fine for an intranet)
  • Sequential or custom URL keyword
  • Handy bookmarklets to easily shorten and share links
  • Awesome stats: historical click reports, referrers tracking, visitors geo-location
  • Neat Ajaxed interface
  • Terrific Plugin architecture to easily implement new features
  • Cool developer API
  • Full jsonp support
  • Friendly installer
  • Sample files to create your own public interface and more

Advanced settings

File includes/load-yourls.php contains a few more undocumented but self explanatory and commented settings. Add them to your own config.php if you know what you're doing.

    • the url to shorten
    • optional keyword and title for custom short URLs
    • output format: either "jsonp", "json", "xml" or "simple"

Pluginsback to top

Plugins?

Plugins are additional PHP scripts that extend the functionalities or features of YOURLS. The core of YOURLS is designed to be as light as possible and avoid bloat (implementing functions not everybody needs) and to allow for easy customization.

Using the plugin architecture, you can add new features to YOURLS without having to modify core files. This way, your changes won't be lost when you upgrade your YOURLS installation and you can easily activate and deactivate a plugin from the admin interface.

There's a growing number of plugins available: check the Plugin list.

Documentation

Several sample plugins are included in the archive. Read the source and learn the concept. It's easy and fun!

Server requirements

  1. A server with mod_rewrite enabled
  2. At least PHP 5.2
  3. At least MYSQL 4.1
  4. Note: YOURLS can also run on Nginx and Cherokee

Server recommendations

Limitations

  • Maximum length of custom keyword is 200 characters
  • That makes about 8 sexdecillions of centillions of available URLs (seriously. That's a 355 digits number).

Difference Between Base 36 And Base 62 Encoding

  • Base 36 encoding uses 0123456789abcdefghijklmnopqrstuvwxyz for short URLs
  • Base 62 encoding uses 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
  • Stick to one setting, don't change after you've created links as it will change all your short URLs!
  • Base 36 is the default and should be picked if you're not sure.

Getting a short domain name for your YOURLS install

  • Unless you plan on making it public and as popular as bit.ly, any shared hosting will be fine. Ozh runs all his YOURLS instance on Dreamhost and it works just great.
  • Domainr is a fun search tool that might inspire and help you
  • Aim for exotic top level domains (.in, .im, .li ...), they're often cheap and a lot are still available. Gandi is a pretty comprehensive registrar, for instance.

YOURLS needs its own .htaccess

  • You cannot install YOURLS and, say, WordPress, in the same directory. Both need to handle URLs differently and need their own .htaccess file.
  • If you want to install YOURLS on the same domain than your blog, give it its own (short) subdirectory, such as yourblog.com/s/ (for "short") or yourblog.com/x/ (for "exit")

If YOURLS generates 404 for your short URLs

  • Make sure mod_rewrite is enabled with your Apache server
  • Make sure your .htaccess file looks like this one
  • Eventually, check your server Apache configuration allows use of .htaccess (AllowOverride All directive, ask your server admin)

There is no index page at the root of the install

  • Indeed. It's intented. It's up to the user to make what they need. Some will redirect the root to a different place, some make a public interface for anyone to shorten links, some make a portfolio. You make it.
  • If you want to make a public interface and run your own little bitly.com, there's a sample file provided as an example: sample-public-front-page.txt. This implies important issues to deal with: spam, performance and security. Read Public Shortening for important information.

Uppercase letters in short URLs are eaten up, eg "OmgOzh" becomes "mgzh" !

  • Indeed. It's intented if you selected Base 36 (see above). Letters that don't belong to the character set, eg @#! or ABC, are removed.
  • If you want to force lowercase, you'll need a plugin.

Feedback, feature requests and bug reporting

  3. Read all the wiki documents.
  4. Search in all the issues, open and closed.
