Best Insider Trading Trackers
Community-ranked insider trading trackers ordered by net upvotes with starred picks breaking close calls.
This curated list focuses on insider buying and selling workflows: Forms 3, 4, and 5, Form 4 alerts, officer and director transactions, 13D/G ownership changes, insider screens, exports, and APIs. We include 13F and filing platforms only when insider or ownership monitoring is a meaningful strength. Use SEC filing search tools for general EDGAR search, filing redlines, exhibit search, and table extraction.

CapEdge is a free SEC filings, transcripts, IPO, ownership, ETF exposure, and short-interest research platform from Finsight for US equity-capital-markets work. It is strongest for investors who want a registered, no-cost workflow around EDGAR search, filing diffs, filing alerts, XBRL financial charts, holdings, and IPO calendars without paying for a filings terminal.

FinancialReports is a public-company filings database, filings API, and hosted MCP server for analysts, AI-agent builders, and data teams that need fast document ingestion, Markdown extraction, watchlist alerts, webhooks, and filing Q&A across global markets. It is strongest when the workflow starts with filings rather than price charts: company documents, insider trades, IPO references, filing feeds, and programmatic document access are the center of the product. The web index is free to browse, while serious API, MCP, webhook, redistribution, and production workflows are contact-sales.

DATAROMA is a free, focused tracker for superinvestor 13F portfolios, recent portfolio changes, and insider buying activity. Use it for value-investing idea discovery and manager-following workflows, then verify timing, filings, and fundamentals before acting.

OpenInsider is a free, utilitarian SEC Form 4 insider-trading screener for investors who want to monitor insider buying, insider selling, cluster buys, and transaction reports without paying for a data terminal. It is useful for fast first-pass insider activity research, but the interface is table-heavy and there is no formal paid support, SLA, mobile app, or documented public API.

HedgeFollow is a web research platform for tracking hedge funds, institutional holders, insider trades, ETF activity, ownership flows, stock pages, fund pages, and portfolio-builder workflows from SEC filings. It is strongest when investors want a fast, visual way to follow 13F, 13D/13G, and Form 4 activity without paying for a larger terminal. The major caveat is timing: 13F holdings are structurally delayed by the SEC reporting process, so the data is useful for research and pattern recognition, not live portfolio mirroring.

Stockcircle is a web app for following disclosed investor portfolios, guru transactions, insider trades, U.S. Congress trades, ETF holdings, valuation pages, screeners, alerts, and Pro-only AI earnings-call summaries. It is strongest for retail investors who want idea generation from reported holdings and public transaction disclosures without manually combing through filings. Pro unlocks fuller history, full screener access, instant notifications, stock picks, ad-free use, and AI summaries. The data is useful but inherently incomplete because SEC reporting rules do not require every holding or smaller transaction to be disclosed.

WhaleWisdom is a 13F, institutional ownership, insider, and hedge-fund holdings platform for investors who track filer activity, fund portfolios, watchlists, backtests, exports, and API workflows. It is useful for holdings research, but 13F data is delayed and the deeper history/API workflow is paid.

Financial Datasets is a developer-focused financial data API and official MCP server for teams building AI agents, stock screeners, portfolio tools, research apps, and quantitative workflows. It is strongest when you need simple programmatic access to U.S. equity fundamentals, prices, SEC filings, insider trades, institutional ownership, news, crypto prices, and screener endpoints without assembling many separate data vendors. The tradeoff is scope and licensing: coverage is centered on U.S. public companies, there is no permanent free tier, and redistribution is gated to Scale or Enterprise.

SecForm4.com is a U.S. insider trading and ownership monitoring site for Form 4, Forms 3 and 5, 13D/13G, and 13F filings from EDGAR. It fits users searching for SecForm4, insider trading trackers, Form 4 activity, and 13D/13G monitoring, with free public access and advanced ownership views for power users. The right use case is monitoring SEC filing signals before checking transaction context, issuer fundamentals, and current ownership. It is not a broker, global insider-disclosure database, portfolio tracker, public API, or standalone buy/sell signal.

13F Insight is an SEC-filings intelligence platform for investors who want to track institutional 13F holdings, Form 4 insider trades, 13D/G ownership, watchlists, smart-money alerts, and AI answers grounded in filing citations. It is strongest for hedge-fund and institutional-ownership research, but 13F filings are delayed by design and AI summaries should be checked against the underlying SEC documents.

InsideArbitrage is a paid event-driven investing research platform for merger arbitrage, insider transactions, spinoffs, buybacks, CVRs, tender offers, activist campaigns, and other special situations. It combines screens, trackers, calendars, deal updates, newsletters, and portfolio/watchlist workflows for investors who actively follow corporate events. It is not a broad fundamentals terminal, broker, portfolio accounting system, or public market-data API.

Insider Monitor is a free U.S. insider-trading reference site for tracking SEC Forms 3, 4, and 5 across insider purchases, sales, officer cluster buys, and top insider-buying lists. It is useful as a quick, no-login way to spot recent Form 4 activity and then jump back to the original SEC filing. Because insiders can report trades after the transaction date and the site does not advertise alerts, exports, or an API, it should be treated as a lightweight research prompt rather than a complete monitoring system.

Insider Screener is a global insider-trading research platform for investors who want to screen, track, export, and alert on director and insider transactions across multiple markets. It is more structured than a simple Form 4 list because it standardizes activity across jurisdictions, supports saved screens and tracked stocks on paid plans, and offers a separate REST API for insider transaction data. Use it as an insider-activity signal layer, not as a complete investment thesis, broker, portfolio accounting system, or unrestricted bulk-data feed.

InsiderScore, now part of VerityData, is an institutional research and data product for insider transactions, buybacks, management changes, institutional holdings, Form 144, 10b5-1 disclosures, and related event feeds. It is built for professional research teams that need cleansed and contextualized event data, not a self-serve retail app, broker, or raw free SEC filing viewer.

Tracefour is a free insider-trade heatmap for investors who want to scan U.S. insider filings, selected European director-dealing disclosures, and U.S. Congress trades in one browser view. It is useful when OpenInsider's U.S.-only Form 4 scope is too narrow, but it should be treated as a discovery layer rather than an institutional data feed because public pages do not publish an API, export workflow, commercial SLA, or data-license terms.

SEC API is a commercial SEC/EDGAR API suite for developers, quants, compliance teams, and AI products that need fast filing search, real-time feeds, XBRL-to-JSON conversion, section extraction, insider filings, 13F data, and other structured regulatory datasets. It is strongest when you want production-ready normalized SEC data instead of building your own EDGAR ingestion stack, but the free tier is only a small starter allowance and redistribution requires enterprise terms.

BamSEC is a web-based SEC filings and transcripts research platform for investors and analysts who need faster EDGAR workflows. It is strongest for document search, filing redlines, table extraction, transcripts, insider and institutional ownership, watchlists, alerts, highlights, and source-link sharing, with most professional workflows gated behind Pro or Enterprise.
