B64 is a URL redirection service powered by nothing except vanilla JavaScript. You can intelligently redirect people based on their platform. (Developers: Your data is put in a JSON array and encoded as base64! That base64 is placed after the URL to create the link. No server needed!)
ArrayCat is a free tool for converting a list of data into an array. For example, you can convert CSV file into PHP array. Or, into a JavaScript array. Or even into an SQL insertion thingie, which is technically not an array.
