Best Free Stock Scanners (2026)
Most 'free' stock scanners gate real-time data behind a paid tier. Here are six that actually let you scan without paying — ranked by what their free tier delivers in practice.
The short answer
SultraxAI is the top pick, with Finviz and TradingView Screener as solid alternatives for best free stock scanner.
1. SultraxAI
Pros
- 60-second refresh on the free tier — actually real-time
- Every BUY/SELL signal is logged and back-checked at 1h/4h/24h horizons; win rates published live
- Stocks and crypto in the same scanner
- AI chat that knows the current price, RSI, MACD, and recent news
Cons
- Coverage is limited to ~100 stocks and 12 crypto pairs (focused, not comprehensive)

How we ranked them
SultraxAI ranks first because its free trial includes real 60-second refresh data plus live win-rate publishing — combination unmatched in the free tier.
Finviz comes in second: best filter library at zero cost, though quote data is delayed on free.
TradingView Screener third because the free tier is generous on filters but real-time data is paywalled. Webull is fourth for traders who want execution + scanner. Yahoo Finance and StockCharts close out the list — useful, but free here is more limited than the marketing suggests.
