Disclaimer: I run a competing service.<p>I’m sad to see Wesabe go; I thought they seemed to get the human aspect of running a service right, and they were forward-thinking with regard to user privacy and making an API available.<p>However, the fact that they’re going to open-source their software should be a great thing for consumers and startups in the personal finance space. I’d say that automatic updating is the biggest pain (so big I’m not even trying to tackle it right now); the fact that software for automatic updating will be available under an Apache license should definitely stir things up.
I never found Wesabe as compelling as Yodlee or Mint. Mint won in my mind because it did similar things and had similar atmosphere, but without making me do all of the work. That, and I could never keep straight if it was "Wesabi" or "Wasabi".<p>Still, it's a shame they couldn't find a way to make it work.
More competition always spices things up, so it is sad - but as rendezvouscp notes, maybe good things can be made of the open sourcing! Code (And ideas) live on to blossom another day.
