Yes. OpenInsider has been a free SEC Form 4 tracker since 2011, with no account, no signup and no email gate. It pulls US insider transactions from EDGAR and renders them as a sortable HTML table, updated within hours of each filing. Tracefour is also fully free, with no paid tier. It shows the same EDGAR Form 4 data and adds European markets, US Congress trades and a visual map on top.

What is the best free alternative to OpenInsider?

Tracefour is the closest free alternative for anyone who wants more than a US-only table. It reads the same SEC Form 4 filings from the same EDGAR source, then adds four things OpenInsider does not have: United Kingdom, Sweden and Germany insider filings; US Congress STOCK Act trades; the Insider Map treemap; and a free account that tracks up to four tickers, four insiders and four members of Congress. For European filings specifically, Insider Screener is the widest paid option; Tracefour is the free one.

Does OpenInsider cover Congress stock trades?

No. OpenInsider is corporate-insider (SEC Form 4) data only, with no US Congress STOCK Act disclosures. Tracefour's /congress page plots House and Senate Periodic Transaction Reports on the same price chart as the matching Form 4 filings, and flags tickers where both a member of Congress and a corporate insider traded inside the same 60-day window.

Does OpenInsider cover UK or European insider trading?

No. OpenInsider is US-only. There is no FCA, BaFin or Finansinspektionen data. If you searched "openinsider uk", Tracefour's /uk page is the free equivalent: UK PDMR director dealings from the FCA National Storage Mechanism, refreshed hourly, with /se (Sweden) and /de (Germany) pages alongside.

Does OpenInsider have cluster-buy detection?

OpenInsider has a saved "Latest Cluster Buys" screener URL that lists companies with multiple recent insider purchases. Tracefour's /clusters page does the same job and adds a 0-100 conviction score, a fixed 60-day same-direction window, and a mini price chart with each filing plotted. It is a free alternative to OpenInsider's cluster-buys screen with more context per row.

OpenInsider vs Tracefour: which should I use?

Use OpenInsider when you want the fastest possible US-only table and already know exactly what you are looking for. Its minimalism and years of bookmarked screener URLs are genuinely hard to beat. Use Tracefour when you want European filings, Congress trades, a visual map, conviction-scored clusters, or a free account to track specific names. Plenty of people use both: OpenInsider for a quick US table, Tracefour for everything it does not cover.

Here's the straight, feature-by-feature version.

Where OpenInsider still wins

Speed and habit. There's no account and no chrome. You open the page and the latest US Form 4 filings are right there in a sortable table. Its table runs wider than ours in places (it shows shares owned and the percent change in each insider's holdings inline), and after a decade online, plenty of people have its screener URLs bookmarked and won't switch on a whim.

Where Tracefour goes further

Everything OpenInsider leaves out, and still free: UK, Swedish and German insider filings, US Congress trades, the Insider Map, conviction-scored clusters, consecutive-week streaks, and an account that remembers the names you follow.
