## 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

## WallStreetZen

**US stock research site with the Zen Ratings A–F composite, computed DCF fair values and analyst accuracy tracking; free plan for life.**

**Kimler için:** Part-time US investors who want an opinionated rating plus a computed fair value at a low price — not global coverage or power tools.

Artıları:
- Zen Ratings composite (115 factors, 7 component grades) is free on virtually every US-listed stock
- Computes its own DCF fair value per stock — it does not stop at analyst price targets
- Measures and ranks analysts by historical accuracy; follow up to 200 of them
- Cheap entry: $1 two-week trial, about $234 per year, 90-day money-back guarantee

Eksileri:
- US-listed stocks only, stocks only (no ETF screening), and web only — no mobile app
- Users have caught glaring ownership-data glitches (institutional ownership above 100%)
- Heavy gating: most columns show “Unlock” until you pay, and add-on newsletters reach $997 per year
- Marketing overstates reach — “thousands more globally” copy against a product that screens four US venues
