Sample Applications

Check out our PostageApp GitHub page for a full list of our plugins and example apps.

Create your own plugin!

We'd love if you could contribute a plugin for a language/framework you use. Bonus points if it's on GitHub and can be easily forked and contributed to. More bonus points if your plugin sends `User-Agent` string as part of the request to identify itself. For example, the PostageApp Ruby gem sends: PostageApp-RubyGem 1.0.0 (Ruby 1.8.7, Rails 2.3.5) as its User-Agent.
