## GuruFocus

**Value-investing research platform with a deep screener, guru 13F tracking and 30 years of financials; priced per market region.**

**Kimler için:** Value investors who research deeply, want guru tracking and long financial history, and mostly work one market region.

Artıları:
- Thirty years of financial history standard (forty marketed), with delisted stocks on the top tier
- Screener combines fundamental, technical and custom-expression filters with real backtesting to 2006
- Guru and insider tracking at scale: 13F portfolios of 8,000+ institutions, funds and politician trades
- Documented valuation stack: GF Value, GF Score, two DCF variants and the Graham Number

Eksileri:
- Every market region is a separate subscription ($369–549 per year each) — multi-market investors pay multiples
- The free account is a research teaser: screener results are masked beyond the first rows
- Rigid billing (non-refundable, cancellation via support ticket) and weak charting — a review quoted on their own pricing page recommends charting elsewhere

## 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
