Maybe a little more than half-baked, but I wrote https://thetortoise.io https://thetortoise.io It's a monte-carlo powered retirement simulator. I use it from time to time to do my own planning. I thought people would like it, but I think it's a little too complicated for most people. I think it's pretty neat though - the best part is that it lets you do what-ifs and compare different scenarios, so you can see how financing that addition to your house compares to paying cash, for example. I haven't worked on it in a while, but might circle back around to it in the next few months.
