Best Free Web Investing Tools

FINVIZ

FINVIZ is a fast U.S. stock screener with heat maps, quote pages, news, insider activity, and watchlists. It turns a market overview into a stock list using fundamental and technical filters. The free version is delayed; Elite adds real-time data, intraday charts, alerts, exports, API access, and deeper ETF and portfolio tools.

Free access shows the workflow; paid and Advisor tiers add history, reports, alerts, integrations, and client portfolios. There is no public API.

OpenInsider

OpenInsider is a free SEC Form 4 screener for insider buying, selling, cluster buys, and transaction reports. It is useful for quick table-based research, but there is no formal support SLA, mobile app, or documented public API.

Perplexity Finance

Perplexity Finance combines cited AI answers with stocks, ETFs, funds, crypto, options, news, charts, screens, earnings documents, ownership, government-trading views, and a finance_search tool. Answers still need verification, and consumer plans are billed separately from the API.

Portfolio123

Portfolio123 combines stock and ETF screens, ranking systems, point-in-time backtests, portfolio tracking, broker links, DataMiner, and API access.

Quartr

Quartr provides earnings calls, live transcripts, filings, reports, decks, estimates, AI chat, and investor-relations data. The app is useful for free call and transcript access; Pro and API serve professional research, MCP, webhooks, and integrations.

Roic AI

Roic AI provides company financials, ratios, valuations, transcripts, news, stock screens, spreadsheet add-ins, a REST API, and an MCP server. Plans differ by request rate, history, price-data latency, and commercial-use rights.

SEC API (sec-api.io)

SEC API is a commercial EDGAR service with filing search, real-time feeds, XBRL-to-JSON conversion, section extraction, insider filings, 13F data, and other regulatory datasets. It is for production ingestion rather than building your own parser. The free tier is small and redistribution needs enterprise terms.

SEC EDGAR - Company Filings (Full‑Text Search & Search Filings)

SEC EDGAR is the free public source for company, fund, insider, ownership, prospectus, and XBRL filings submitted to the SEC. It has full-text search, latest filings, RSS, CIK lookup, public JSON APIs, archives, and bulk files. Most filings still need parsing before comparison or analysis.

SEC.gov (EDGAR)

SEC.gov EDGAR is the official free source for U.S. company, fund, insider, and 13F filings, with full-text search, RSS, bulk archives, and public JSON APIs. It is the validation source for filings research, not a polished commercial terminal.

Seeking Alpha

Seeking Alpha combines market news, contributor research, Quant Ratings, analyst ratings, portfolio alerts, screens, and earnings transcripts. It is useful for idea generation and monitoring. Premium and PRO add deeper research, AI summaries, full transcripts, factor grades, and portfolio tools.

Short Interest - FMM

Find My Moat Short Interest is a free, searchable tracker for U.S. stocks with short interest above 20%. It is a discovery table with plain-language context, not a trade signal, export feed, or API.

Simply Wall St

Simply Wall St provides visual company reports, fair value estimates, dividend analysis, portfolio checks, broker imports, and global stock ideas. It suits long-term investors who prefer guided research to raw tables.

Stock Analysis

Stock Analysis combines screeners, financial statements, calendars, news, charts, forecasts, watchlists, and portfolios on web and mobile. Paid plans add longer history, higher limits, exports, ETF holdings, broker sync, and analyst filters. The service does not provide brokerage execution, advice, or programmatic data access.

TIKR

TIKR is a browser equity-research terminal for global fundamentals, statements, estimates, valuation, transcripts, filings, and screens. It suits long-term stock research; paid plans add history, coverage, exports, and higher workflow limits.

TipRanks

TipRanks combines analyst ratings, targets, expert rankings, Smart Score, AI analysis, news sentiment, insider signals, hedge-fund activity, and portfolios. It is useful for comparing market views quickly, with Premium and Ultimate adding deeper expert, portfolio, export, and AI tools.

TradingView

TradingView combines charts, screeners, alerts, Pine Script, paper trading, and broker connections across many asset classes. Basic is free. Paid plans raise chart, indicator, alert, watchlist, history, and portfolio limits. Some real-time exchange data costs extra.

Uncle Stock

Uncle Stock screens more than 100,000 global stocks with financial metrics, valuation models, scores, historical tests, watchlists, and alerts. Gold adds CSV and JSON access, an MCP server, and limited portfolio tracking. It is not a broker or an intraday trading simulator.

Unusual Whales

Unusual Whales tracks options flow, dark pools, congressional trades, insider activity, market data, alerts, screeners, and social sentiment. It is built for active traders and alternative-data research, not a broker, portfolio ledger, or guarantee that unusual activity predicts returns.

13F Insight

13F Insight pulls institutional holdings, insider trades, and ownership filings into one research workspace. Its AI can answer questions with filing citations, but the filings arrive late and the generated summaries still need a check against the SEC documents.

Ahrefs

Ahrefs gives investors a way to check the web demand around digital businesses, publishers, marketplaces, SaaS companies, and consumer brands. It measures search traffic, keywords, backlinks, and AI visibility. Those numbers are estimates, not company filings or a portfolio system.

Alpha Spread

Alpha Spread combines DCF and relative-value estimates, stock reports, screens, alerts, analyst forecasts, watchlists, and a company-question assistant. Free use is metered weekly.

Alpha Vantage

Alpha Vantage is an API-first source for market and economic data. Developers, students, quants, and analysts can pull stocks, funds, FX, crypto, options, commodities, fundamentals, news, sentiment, and macro series with one key. The free quota is small, and commercial use needs separate licensing.

AlphaResearch

AlphaResearch puts filings, transcripts, press releases, estimates, news, insider trades, ownership, and fund holdings in one searchable workspace. It is aimed at document-heavy research. Global coverage and spreadsheet add-ins require Enterprise, and the premium trial asks for a card.

ApeWisdom

ApeWisdom tracks ticker mentions across Reddit, WallStreetBets-style forums, crypto communities, and 4chan /biz. It is useful for seeing where retail attention is moving. Mentions are noisy, so a leaderboard is not a view on value or price direction.

AUM 13F

AUM 13F is a low-cost filing research app for asset managers, institutional holdings, private funds, real-estate managers, and LP relationships. It brings together AUM, 13F holdings, EDGAR, IAPD, CAFR-sourced portfolios, source links, and alerts. The underlying filings are still delayed and incomplete.

Bank of England

The Bank of England site is the primary free source for UK monetary-policy decisions, MPC minutes, Monetary Policy Reports, rates, exchange rates, statistics, and yield-curve files. It is a reference source for macro research, not a trading app. Some series arrive as downloads rather than through a complete API.

Bank of Japan (BOJ)

The Bank of Japan site publishes Japan's monetary-policy releases, meeting calendar, statistics, charts, time-series downloads, and API access. It is useful for primary-source rates, FX, money stock, TANKAN, balance-of-payments, and central-bank data. It is not a security research or trading terminal.

Beanvest

Beanvest gives long-term investors a compact quality-investing framework. Its stock reports score moat, pricing power, predictability, financial strength, capital allocation, and management, then add fair-value labels and a quality screen. Coverage is selective, premium data is gated, and there is no free trial.

Berkshire Hathaway Archive (Memorex)

Berkshire Hathaway Archive by Memorex is a free searchable collection of Warren Buffett shareholder letters and Berkshire annual-meeting transcripts. Search it for the company's thinking on capital allocation, incentives, moats, management, insurance, and long-term investing. It covers one company, not the wider market.

BIS Data Portal

The Bank for International Settlements' free data portal covers banking, credit, debt, derivatives, liquidity, property prices, exchange rates, central banks, and payments. It includes charts, downloads, a release calendar, and an SDMX API.

BizToc

BizToc aggregates business and finance stories in a configurable grid and chronological Wire feed. It also provides a market snapshot, imagery view, search, RSS, and a RapidAPI feed. Users should open the original publisher before relying on a story.

Bloomberg (Europe)

Bloomberg Europe is the regional Bloomberg.com newsroom and app experience. It offers European and global business reporting, market snapshots, watchlists, alerts, TV, radio, podcasts, newsletters, and Businessweek. It is a media subscription, not Bloomberg Terminal, execution, or institutional data access.

Börsdata

Börsdata gives investors long-history Nordic fundamentals, ratios, screens, ownership, insider and short-selling data, technical charts, reports, watchlists, calendars, and spreadsheet or API access. It is strongest for Nordic equities. Global data, holdings, Excel or Sheets workflows, and the REST API depend on the plan.

Bridgewater Associates

Bridgewater's public site is a research library, not a self-serve way to invest with Bridgewater. It is useful for reading the firm's macro work on Pure Alpha, All Weather, risk parity, inflation, monetary policy, debt cycles, and systematic investing. The site does not open Bridgewater mandates to ordinary investors.

Business Quant

Business Quant covers U.S. company fundamentals, operating KPIs, segment data, analyst estimates, institutional ownership, and insider trades. It is useful when company-specific operating measures matter alongside standard financial statements. The free plan limits KPI history and API usage, while paid plans increase history and usage allowances.
