There are a number of free finance tracking sites out there like mint.com, wesabe.com etc.. .
I've tried all of them and all seem to miss the mark in one way or another. I'm interested in creating my own website, or possibly just a stand alone windows program for tracking my finances in ASP.NET or C#.NET.
I'm assuming the answer is no, but is there any way that a personal developer can download transactions from financial websites like these? I know once you login to most financial sites you can download a CSV or Quicken file. Yet I really like how I can log-in to my Mint.com account and update all my accounts with one click.
Popular applications (like Quicken) and most major US banks support Open Financial Exchange (OFX). If a bank can connect to Quicken, it probably supports OFX (though not guaranteed).
