Mint

Possibly the most comprehensive budgeting website, Mint aggregates and links all of your accounts (checking, savings, credit cards, insurance, investments, student loans and even retirement accounts), lets you set up monthly budgets, create goals (like saving for a down payment on a house or paying off that credit card), and even looks for ways to save you more money by analyzing your credit card APR and what you spend the most money on.
Manilla

Always forgetting when that bill is due? Manilla is the answer. It links utilities and other bills so you never miss a due date, and you can even add magazine subscriptions, loyalty reward programs and deal vouchers, like those from Groupon or Livingsocial.
PayDivvy

If you've lent some money to a friend and don’t want to make things awkward, send them a reminder with this nifty tool. PayDivvy allows you to pay or collect money from friends and family and split group expenses (like those vacations or a big meal). It’s harder to ignore when it’s in black and white, no?
MyCabbage

Never going to use that skydiving package for two you bought on a whim? Go to MyCabbage to sell it—fast! You can place deals up for sale, and also look for deals that expired before you could nab them. (And next time, save yourself the headache by not buying anything you won’t absolutely use!)
