Best Free Fund Analysis Tools for Investors

Koyfin

DetailsVisit site

Koyfin is a modern web and mobile financial terminal for investors, analysts, and advisors who want dashboards, charts, screeners, portfolios, news, alerts, transcripts, and market data without using a traditional desktop terminal. It is strongest for building custom research workspaces across equities, ETFs, funds, macro data, FX, commodities, crypto, yield curves, and advisor reporting. Free access is useful for trialing the workflow, while paid and Advisor tiers unlock more dashboards, screens, history, alerts, reporting, integrations, and client-portfolio features. It does not offer a public API.

Stock Rover

DetailsVisit site

Stock Rover is a web-based stock, ETF, fund, and portfolio research platform for investors who want 800+ financial metrics, 20 years of historical fundamentals, deep portfolio analytics, dividend tracking, automated DCF-driven intrinsic value and Margin of Safety tools, printable research reports, stock ratings, broker-linked portfolios, and alerts. It is strongest for North American fundamental research and portfolio management, not for trade execution or full strategy backtesting.

Office of Financial Research (U.S. Treasury)

DetailsVisit site

Office of Financial Research is a free U.S. Treasury source for official financial-stability monitors, stress indicators, short-term funding data, money-market fund transparency, bank systemic-risk views, and hedge-fund monitor datasets. It is useful for macro, risk, policy, and market-structure research where documented methodology and public JSON or CSV access matter more than a polished investing app. OFR data is generally monitor-specific and often end-of-day or lagged. It is not a real-time market-data feed, stock research terminal, broker, portfolio tracker, or broad trading dataset.

Snowball Analytics

DetailsVisit site

Snowball Analytics is an EU-based portfolio and dividend tracker for retail investors who want multi-asset tracking, broker import, dividend analytics, benchmarking, fund look-through, backtesting, and mobile access. It is useful for long-term portfolio monitoring, but it is not a broker, registered investment adviser, tax filing product, or professional performance-composite system.

Delta by eToro

DetailsVisit site

Delta by eToro is a multi-asset portfolio tracker for stocks, ETFs, funds, crypto, NFTs, forex, commodities, indices, brokers, exchanges, and wallets. Use it when you want one read-only portfolio view across accounts and asset classes rather than another place to trade.

FinancialData.Net

DetailsVisit site

FinancialData.Net is an API-first financial data platform for developers, analysts, spreadsheet users, and AI-agent builders who want broad market data, fundamentals, ownership, options, funds, ESG, calendars, news, Excel access, and MCP connectivity from one provider. It is strongest when breadth matters: stocks, ETFs, mutual funds, options, futures, crypto, forex, commodities, OTC securities, indices, filings-related datasets, and institutional/insider activity can sit behind one REST API. Serious use is paid, and compliance/security claims should be verified directly because the local profile does not include public audit reports.

FT Markets (Markets data - Financial Times)

DetailsVisit site

FT Markets is the Financial Times market-data portal for global equities, funds, ETFs, bonds, commodities, currencies, watchlists, portfolios, alerts, charts, and screeners. It is useful for readers who want credible market tools close to the FT news workflow rather than a standalone professional terminal. Free registration unlocks practical tracking tools, but deeper company data, director dealings, archive PDFs, and parts of the broader FT experience can require a subscription, and market data is delayed.
