This is a fantastic project. Thank you for releasing it!
Do you have a plan to expand with new features and are you looking for contribution?
Will the database be updated automatically?

#12Whalewisdom and gurufocus have similar offerings. Not sure if they are 100% free.
Yeah, I'll throw my SEC Filings site https://Last10K.com into the mix too that has a free feature on how a manager's portfolio changed by tagging which stocks are new / sold / increased / decreased from the previous to current quarter. Here's an example from the OP's "Popular" and "Top" filers:
Tiger Global: https://last10k.com/sec-filings/1167483
Ruane, Cunniff Goldfarb: https://last10k.com/sec-filings/1720792

#13Feedback is: by making this an npm thing, you reduce the pool of people that will use this. This should really be a lib that takes a folder of 13F forms and outputs a csv, or something like this. That's it. No need for webapps or whatever.
There's actually a couple of libraries that already do this, and this project can probably function like a libary if edited here and there.
The problem I found though is that you can't really just use the raw filings. The data is much more useful when the stocks are queried with third party APIs and organized along with things like recent price data. This project alone uses three APIs, and while you could include that in a library and force the developer to get three different API keys, it just works better as a service.
If a "library" is all you want though, the API is available with documentation. There's also 13.info, an open-source project that predates this one. Although it is still a service, it is more like a library and could probably be used like one.

#14I have learned something today, thank you for that! The pitch is clear and the fact that you put so much work in open sourcing it is really impressive.

#15This is a cool concept, great job on the project so far!

I plan to add a lot of features, and all suggestions are appreciated.
As for contribution, I am definitely looking for it. I have not been in the open-source field for long so I don't exactly know how to get it, but I would highly appreciate it if anyone could help.
Contribution would be especially helpful since I was still learning a lot of the technologies I used while I built this project, and the code is prone to newbie mistakes.

#18Impressive work. Just a small comment - It seems to not able to track the prices after bonus or a stock split.
If you can adjust the paid price for stock to account for that. Like for google i see the price: $1413.61

#19Dang, I saw the name and hoped it was a map-based app that showed you ownership of things around you (further intriguing me because I don't believe such data exists at a local scale anyway). Great project though! Opening up these sort of semi-encumbered datasets is what keeps humans well informed I'm from MI as well and always wondered about deeper datasets for watching money and influence change hands
There are a lot of GIS / mapping software that shows property ownership and their boundaries, useful for hunting. onX, for example, and I think you can purchase 'ownership layers' on stuff like Avenza.
I agree with what you're saying though, it would be cool to take something like those property owner layers and find the ultimate legal entity for stuff like LLCs owning land.
E, only semi-related: In the 'urban design' part of the internet I've seen really cool mapping that puts bar charts on top of a city's grid, with the bar charts being how much tax revenue the city generates. It's really stark to see skyscraper-sized bars in downtown cores and mostly flat all around where cities have zoned residential separate from commercial, or even where suburbs tax less than the core city.
