Best Free Stock Screeners in 2026 (Tested and Ranked)

Free stock screeners vary enormously in what they offer without a subscription. Some provide genuine filtering capability with extensive fundamental data. Others are effectively demos that hit paywalls at every meaningful step.

This ranking covers the best free options in 2026 for investors focused on fundamental and value-oriented analysis — including what each platform genuinely provides for free and where upgrades matter most.

1. Finviz (Free Tier)

Best free screener overall for filter breadth

Finviz's free tier is legitimately useful. It includes the full filter-based screener with 70+ criteria across fundamental ratios (P/E, P/B, P/S, EPS growth, debt/equity, ROE, ROA), technical indicators, and analyst ratings. Data is end-of-day (delayed), but the filtering capability is complete.

What the free tier lacks: real-time data, email alerts, backtesting, correlation analysis, and the advanced chart features that come with Elite ($299/year). For basic screening workflows that don't require real-time pricing, the free tier covers most needs.

What you get free: Full filter screener with 70+ criteria, end-of-day data, U.S. equities including small-caps and OTC, fundamental ratios, analyst ratings.

Limitation: No intrinsic value calculation. Finviz does not run DCF models or estimate fair value in any tier.

2. Equity Rank (Free Tier)

Best free tier for valuation-focused investors

Equity Rank's free tier gives access to the public screener showing top-ranked stocks by SAVE score, limited individual stock lookups with valuation data, and basic margin of safety information. The 7-day free trial of the full Pro plan is also available without a credit card — the most extensive free evaluation period among comparable platforms.

What the free tier shows is meaningful: SAVE scores, margin of safety direction, and basic valuation model outputs for top-ranked stocks. The limitation is depth — the full 15+ model breakdown, screener filters, and options tools require a Pro subscription.

What you get free: Top-ranked stocks by SAVE score, limited stock lookups with valuation data, 7-day full Pro trial (no credit card required).

Limitation: Full screener filtering (by margin of safety, sector, individual model), complete SAVE score breakdowns, and options data require Pro.

3. Yahoo Finance (Free)

Best free tool for broad market data

Yahoo Finance's screener is fully free and covers U.S. and international equities. Filters include P/E, P/B, EPS growth, market cap, sector, analyst ratings, and more. It also integrates earnings calendars, news, and analyst estimate history — making it a useful starting point for broad fundamental scanning.

The screener's strength is breadth and accessibility. Its limitation is analytical depth: no intrinsic value models, no composite scoring, no margin of safety calculation. Yahoo Finance is excellent for initial discovery and news tracking, but thin for systematic valuation research.

What you get free: Full screener with fundamental filters, U.S. + international coverage, earnings calendar, analyst estimates, news integration.

Limitation: No valuation modeling, no composite scoring, no margin of safety.

4. Koyfin (Free Tier)

Best free terminal-style tool

Koyfin's free tier is notably generous for a professional-grade platform. It includes basic financial data, charting, watchlist functionality, and limited access to the data terminal for exploring fundamentals. The Growth plan ($39/month) adds real-time data, advanced screener features, and analyst estimates depth.

For investors who want terminal-style access to financial data without paying Bloomberg prices, Koyfin's free tier is one of the better options. It won't replace a dedicated valuation screener, but it's a strong research complement.

What you get free: Basic financial charting, limited fundamental data, watchlists, simplified screener.

Limitation: Real-time data, full screener capability, advanced charting, and analyst estimates require paid plans.

5. WallStreetZen (Free Tier)

Best free tier for readable fundamental summaries

WallStreetZen limits free users to a set number of stock lookups per day, but what those lookups show is genuinely informative: color-coded fundamental ratings, the Zen Score, and plain-language explanations of each metric. For investors who want to quickly understand whether a stock's fundamentals are healthy, the free lookups are useful.

The DCF calculator and full screener require a paid subscription, and the daily lookup limit makes it impractical for screening large universes without paying.

What you get free: Limited stock lookups with visual fundamental summaries, Zen Score, plain-language explanations.

Limitation: Daily lookup cap, full screener and DCF tool require subscription.

---

6. Simply Wall St (Free Tier)

Best free tier for global equity health checks

Simply Wall St's free tier includes a limited number of individual stock analyses per month. The snowflake visualization and narrative analysis are available within that limit. For investors checking a small number of specific stocks — particularly international equities — the free tier provides meaningful output.

The screener and unlimited stock analysis require a paid subscription, but the free tier is useful for targeted individual stock checks.

What you get free: Limited monthly stock analyses with snowflake visualizations and narrative summaries. Global coverage.

Limitation: Monthly analysis cap, screener requires subscription.

Frequently Asked Questions

Is Finviz completely free? Finviz's free tier includes the full filter-based screener with end-of-day data and most fundamental filters. Real-time data, email alerts, correlation analysis, and backtesting require Elite ($299/year).

Does any free screener calculate intrinsic value? Most free screeners display fundamental ratios but do not calculate intrinsic value. Equity Rank's free tier and 7-day trial provide access to fair value estimates and margin of safety data, which is uncommon among free tools.

What is the best free stock screener for beginners? Yahoo Finance and Finviz are the most accessible starting points — both are fully free, widely used, and require no account to use basic features. WallStreetZen's plain-language explanations are particularly useful for investors learning fundamental analysis.

Is Yahoo Finance good enough for value investing research? Yahoo Finance is useful for initial discovery, news tracking, and basic fundamental data. For systematic value investing — with intrinsic value models, margin of safety filters, and earnings quality scoring — it lacks the specialized tooling that dedicated valuation platforms provide.

Do I need a paid screener? For casual market awareness, free screeners are generally sufficient. For systematic value investing — running multi-model valuations, filtering by margin of safety, and scoring earnings quality across a universe — the analytical depth of paid platforms provides enough incremental value to justify the cost.
