Since my last tier list did so well I though I'd make a part 2. Just to preface this is my own personal opinions from data providers I have used, I am an undergraduate economics student at Cambridge looking to break into Quant Research next year no need to grill me in the comments below.
**London Strateigc Edge**: Tickdata for all US stocks and options+ economic data for all countries **FOR FREE** just a massive archive of data. Everyone gets an api key with 50gb of data usage +100 websocket connections. Unfortunately no level 3 data which makes sense as exchanges charge per user who views the data.
**Databento:** If you need **Level 3 data** this is your place to go, all US exchanges covered + EUREX unfortunately in the 200usd plan live web sockets for l3 data not included. free $125usd credit for signup too
**Alpaca:** $100 for access to all US Exchanges for stocks and options data, includes websocket connections for all stocks and options definitely the **best price option out of all the paid providers** for websocket connections.
**Massive:** Biggest archive of historical data for US exchanges 20+ years, offers **alternative data** like credit card reports. Extremely easy to download the data. Free plan is meh.
**FMP :** Access to different exchanges like LSE, EUREX and other niche providers but low quantity of historical tick data.
**Rithmic:** API service offered through brokers like AMP futures, best price for **level 3 futures data** but slightly more complex to setup straight out of the box.
**Yahoo Finance: Free historical data** for a wide range of assets but London strategic edge providers more detailed data.
**Tiingo: $30 USD for all US exchanges data**, unfortunately 30gb bandwidth limit.
**EODHD + Alpha vantage + Finnhub:** intuitive api to use but just use alpaca + FMP for the same data but a lot cheaper
