CRSP covers prices and returns; Valuein covers SEC fundamentals.
CRSP (the Center for Research in Security Prices, now offered through Morningstar Indexes) is the academic reference for US stock prices, returns and corporate actions on active and inactive securities. It is a market-data product, not a fundamentals product, so the two are complements more than rivals. Valuein provides point-in-time SEC fundamentals.
The short version, including where CRSP is the better pick.
CRSP and Valuein answer different questions. CRSP's public page describes daily and monthly market data and corporate actions for more than 36,000 active and inactive securities. Valuein supplies the SEC-filed fundamentals that CRSP's public page does not describe.
What you get: Standardized SEC fundamentals, ratios, filings.
CRSP is the academic standard for security prices and returns, with history of over 100 years per its product page; Valuein is not a price database for research-grade returns
Quants who already have a price source and need point-in-time fundamentals to pair with it.

Install the SDK and read a company with no token and no card: the free sample runs the same code your plan will. Add a key later and nothing else changes.
from valuein_sdk import ValueinClient with ValueinClient() as client: # What a ticker or CIK resolves to. A CIK also reaches delisted companies. print(client.resolve(["AAPL", 320193])) # One company's rows from a table, with the point-in-time filter applied. facts = client.read_table( "fact", tickers="AAPL", columns=["standard_concept", "period_end", "fiscal_period", "numeric_value"], limit=10, ) print(facts) # Named SQL templates. Pass parameters as keyword arguments. print(client.list_templates()[:5]) df = client.run_template("fundamentals_by_ticker", ticker="AAPL") print(df.head()) # Links to the SEC filings behind the numbers. links = client.filing_links("AAPL", form_types=["10-K"], limit=3) print(links[["form_type", "filing_date", "document_url"]]) # Restatement Radar: figures a later filing changed (every plan). changed = client.restatements(ticker="AAPL", limit=5) print(changed[["standard_concept", "period_end", "first_value", "current_value", "disclosure_class"]])No. CRSP is market data (prices, returns, corporate actions). Valuein is SEC fundamentals. Many quants use both: CRSP-style prices for returns and Valuein for point-in-time fundamentals.
For a factor backtest you typically need prices and fundamentals. Valuein supplies the fundamentals side with filing timestamps, so you can join them to whichever price source you license.
