Rackbin: Simplest possible Rack postbin

Requestb.in is great, except it limits requests to 10,240 bytes, you can't choose your URL path, and it can't handle non-ASCII, non-UTF8 POST requests. This postbin, or "requestbin", is easy to install and customize, has no limits, uses any URL path and accepts all encodings. Just open your bin's URL and wait for the requests!

Getting Started

• Sign up for a Heroku account
• Download the Heroku Toolbelt
• Deploy to Heroku

git clone https://github.com/jpmckinney/rackbin.git
cd rackbin
heroku apps:create
heroku addons:add pusher:sandbox
git push heroku master

• Open your bin's URL and wait for requests

heroku open

• POST requests to your bin's URL

Features

• You can POST and listen for requests at any URL path. For example, /foo displays only POST requests to /foo, making it easy to isolate requests. You must have the bin's page open in your browser before POST requests are sent.
• /rack is a special path that displays HTTP headers as environment variables (and displays only POST requests to /rack). Useful if you are testing webhooks to be consumed by Rack apps.
• Rackbin is less than 200 lines of code, all in config.ru, making it easy to tailor to your needs.
• If you must send non-ASCII, non-UTF-8 POST requests, send your request to the appropriate, case-sensitive path below (otherwise, Rackbin will silently fail). Unlike other paths, you must refresh the bin's page after POST requests are sent. You may need to change your browser's encoding.

Why?

• Some services change their output format depending on the URL. Mailgun, for example, will only deliver raw MIME messages to URLs ending with mime. With Rackbin, you can easily route your requests to e.g. /post_mime.
• Other postbins don't handle non-ASCII, non-UTF8 POST requests gracefully (or at all).

In most cases, you are probably better served by Requestb.in.

Caveats

• Rackbin uses Pusher, which sends messages in 10kB chunks. Sending a large POST (>1MB) is therefore not recommended. (Pusher is used to avoid database maintenance. Rackbin stores no data.)
• URL paths should contain only upper- and lowercase letters, numbers and the following punctuation _ - = @ , . ;. The / path separator is converted to _. All other characters are ignored. As such, /foo! displays the same POSTs as /foo.
• /requests is the default bin, therefore / displays the same POSTs as /requests.
