## Finviz

**Free US stock screener with signature market heatmaps; Elite adds real-time data, alerts and export.**

**Kimler için:** US-market stock pickers and traders who want the fastest free scan-and-shortlist workflow on the web — and are fine typing a ticker universe that ends at the US border.

Artıları:
- Arguably the widest genuinely free stock screener — all fundamental and technical filters usable without an account
- Signature market visualizations: S&P 500 heatmaps, sector/industry/country groups, insider-trading tracker
- Elite is cheap for what it bundles: real-time quotes, unlimited alerts, full export with API, ETF holdings data
- Vendor-curated signal screens plus up to 200 saved presets make daily scanning fast

Eksileri:
- US equities only (NASDAQ/NYSE/AMEX) — the vendor's own FAQ says no international expansion is planned
- Free tier is ad-heavy, and export is entirely Elite-gated — the free plan cannot export a single row
- No mobile app at all, and no language besides English
- The Elite backtester was removed (~2023) — third-party reviews that still praise it are stale

## Koyfin

**Institutional-grade market data and global screening on Capital IQ and Morningstar feeds, at retail prices.**

**Kimler için:** Data-hungry global investors and finance professionals who want Capital IQ-grade fundamentals, estimates and macro in one affordable terminal — and who work inside the platform rather than exporting from it.

Artıları:
- Institutional data sources (S&P Capital IQ, Morningstar) with genuinely global coverage at retail prices
- Deep screening: 5,900+ criteria and separate equity, ETF, mutual-fund and SMA screeners with templates
- Full-spectrum alerts — price, technical, valuation-level and news — delivered to desktop, email and push
- One of the best-rated mobile apps in the category (4.9★ on iOS), actively updated

Eksileri:
- No API at all, by the vendor's own admission — and that is a data-licensing constraint, not a roadmap gap
- Export is hollowed out: financials, valuation, estimates and growth columns cannot leave the platform
- Custom formulas work only as watchlist columns — you cannot screen on them
- Key workflows (model portfolios, more formulas, full history) climb quickly into the $79+/month tiers
