Koyfin overview
Koyfin is a financial data and analytics platform positioned as a serious-investor alternative to Bloomberg Terminal at a fraction of the cost. The product covers stocks, ETFs, mutual funds, bonds, FX, commodities and global macro data, with a deep dashboard-driven workflow built for buy-side analysts and individual investors who want institutional-grade tooling.
The core experience is built around customizable dashboards: each user builds their own combination of price charts, financials, fund flows, earnings calendars, news streams and ratio tables. Beyond the dashboards, the platform covers analyst estimates, peer comparisons, screening, watchlists and portfolio tracking. Coverage is global — international equities, sovereign bonds, FX pairs and macro indicators all live in the same workspace.
What Koyfin doesn't have: alternative-data signals (no social audience tracking, no web traffic, no hiring activity), no AI scoring layer, no signal-based alerts. It's a data terminal — excellent at consolidating traditional financial data into one workspace, but it doesn't try to be an alt-data platform.
Pricing: Koyfin Free is genuinely useful for casual users; Plus ($39/mo billed annually), Pro ($79/mo billed annually) and Pro+ ($149/mo billed annually) unlock more data depth, real-time pricing and advanced features. Pricing has gone up since launch as the institutional-grade reputation has grown.

Koyfin vs AltIndex: the comparison
Koyfin and AltIndex serve different jobs in the research workflow. Koyfin is the data terminal — where you go when you need to pull global financials, compare peers, build a multi-asset dashboard or check macro charts in one place. AltIndex is the alternative-data layer — where you go to check what the underlying alt-data signals (social audience, web traffic, hiring, sentiment, AI Score) are doing on a stock you're researching.
A serious fundamental investor who wants Bloomberg-level data depth on a retail budget gets that from Koyfin. An investor who wants alternative-data signal coverage across social platforms, web traffic, hiring and the AI Score gets that from AltIndex.
The two are complementary. Many investors use both — Koyfin for the financial-data terminal view, AltIndex for the alt-data signal view. If you're building a serious research workflow and only choosing one, Koyfin if you want depth on financials and global macro; AltIndex if you want depth on alternative-data signals.
What AltIndex has that Koyfin doesn't: alternative-data signals across 8 social platforms + web traffic + hiring + news mentions, the AI Score combining them into a daily 0–100 number, signal-breakout alerts (Koyfin's alerts are price-based), and Congressional + insider trade feeds. Where Koyfin wins: institutional-grade financial data depth, global multi-asset coverage, and dashboard customizability.
