finviz VS pysonDB

https://github.com/mariostoev/finviz may be helpful to you

Try https://www.tiingo.com/ pretty cheap data. You might be able to also scrape https://finviz.com/screener.ashx?v=161&ft=2&o=pe and store the data and compare. Useful python package I have previously used. https://github.com/mariostoev/finviz

FinViz Wrapper for Python: https://github.com/mariostoev/finviz

Unofficial finviz

Anytime someone asks this question this unofficial finviz API python wrapper comes up. I would like to point out that all he is doing in this code is scraping finviz. So if you have a screener you like you could do the same

You can use one of the free stock screeners, here's an API for finviz for example: https://github.com/mariostoev/finviz

I use finvizapi to filter on tickers I want (by exchange, market_cap, price), save to a CSV, then loop through each ticker to request data from different data vendors (polygon, tiingo, yfinance, quandl)

https://github.com/mariostoev/finviz allows you to pull finviz's insider data

Have a tl:dr how it differs / improves on pysonDB?

Choice of database depends on your needs and network requirements. If you just want timestamp and a tag ID connected to it I’d recommend pysonDB a simple JSON-based database. If you need to be able to access data outside of the network I’d recommend you to use Googles Firebase with firestore / real-time DB (any should be fine) which would allow you to subscribe to real-time updates. If you want a fancy website connected to this I’d recommend using firebase as it allows for free hosting
