The short version. Finviz is the fastest way to filter the market and it is free. Stock Rover is slower, deeper and starts at $80 a year. Most investors who use both screen in Finviz and study in Stock Rover.
How they compare
Speed against depth
Finviz returns a screen almost instantly across a clean set of common filters, and the heat map is the best free market visual anywhere. Stock Rover screens across roughly 700 metrics with far more logical flexibility, including custom formulas, and it is correspondingly slower to set up.
What happens after the screen
This is where they separate. Finviz gives you a list and a chart, and the workflow largely ends there. Stock Rover keeps going into ten years of financials, peer comparison, fair value estimates and portfolio analytics, so the screen is a starting point rather than the output.
Portfolio analytics
Stock Rover connects to your brokerage and analyses what you already own: allocation, correlation, dividend income, future income projection and rebalancing. Finviz does not attempt this. If you want to understand your portfolio rather than just find new names, only one of these is in the conversation.
Price
Finviz is genuinely useful free, with Elite adding real-time data and backtesting. Stock Rover is free at entry, then $80, $180 or $280 a year. Running free Finviz alongside a paid Stock Rover tier is a common and sensible combination.
Who each one is for
Choose Finviz if you want to filter the market in seconds, read a heat map, and pay nothing.
Choose Stock Rover if you want deep screening, ten years of financials and analytics on the portfolio you already hold.
The third option: build the thesis yourself
Most people comparing Finviz and Stock Rover are really asking a question neither answers: how do I know whether this company is worth owning?
The problem they share. A screen produces a list of tickers. Neither tool tells you which of them is a business worth owning, and a list you cannot evaluate is where most investors quietly give up on individual stocks. That gap shows up at exactly the wrong moment. When a holding falls 30%, you cannot tell a broken business from a temporary drawdown, because you never built the model the thesis rested on.
Stock Simplifier vs Finviz
Finviz is the best free screener available and it stops exactly where the hard part begins. It narrows 8,000 stocks to 20 in seconds and offers nothing to help you work out which of those 20 is a good business.
Stock Simplifier picks up at that handover. Take a shortlist from any screener and it walks you through the business, the moat, management, growth and valuation for each name.
The two are complements rather than substitutes. Screening finds candidates; analysis decides between them, and most workflows stall precisely at that gap.
Stock Simplifier vs Stock Rover
Stock Rover hands you around 700 metrics and no opinion about any of them. That is deliberate and it is genuinely powerful, provided you already know which numbers matter for this company at this stage of its life.
Stock Simplifier runs on the same class of institutional data and adds the layer Stock Rover leaves out: what the numbers mean here, why this metric matters for this type of business, and what the combination implies.
It is also the difference between a spreadsheet and a written thesis. One is a workspace; the other is a conclusion you can revisit and check.
What Stock Simplifier actually does
A guided wizard walks you through seven steps for any stock: the business model, its lifecycle phase, the moat, management, growth, risk and valuation. Real data from Fiscal.ai populates each step, the framework adapts to the type of company, and each concept is explained where it appears. You review, score and decide.
Where it falls short. It will not hand you a stock pick. It covers US-listed stocks only. There is no community, no earnings call transcripts and no portfolio tracker. If any of those is why you subscribe today, keep what you have and add this alongside it.
