SEC Form 4 and institutional filing tracker
The best SECForm4.com alternatives
SECForm4.com alternatives are searched for reasons that have nothing to do with the data, which is good and mostly free. It is a desktop site built for reading tables, with no app, and its premium tier does not publish a price, so anyone weighing an upgrade has nothing to weigh. What people usually want next is the same insider filings somewhere they will actually see them.
7 options below, including ours: the ones closest to what SECForm4.com is actually for, ordered by how close — not ranked best to worst. The right pick depends on whether your problem is choosing stocks, following them, or tracking a portfolio. We compare 37 tools in all.
7 alternatives to SECForm4.com
AI stock tracker
Our appStockPlus
A daily AI market briefing, a real-time watchlist with a 0–100 Pulse Score, price alerts, and congressional and insider trade feeds.
- Best for
- Keeping up in two minutes a day
- Free tier
- Yes
- Paid from
- $2.99/mo Pro
Congress and insider trade tracking app
StockInsider
An App Store congress-and-insider tracker that bundles congressional disclosures, 13F holdings and Form 4 filings with AI features on top, sold through in-app purchases.
- Best for
- Volume of smart-money surfaces in one app. Congressional trades, 13F institutional holdings, corporate Form 4 filings, an AI "Policy Pulse" feed of tariff and sanction events, a Bull and Bear case view, 35 backtested strategies and an AI screener all sit in the same product. Nothing here matches that count, and the App Store rating is a genuine 4.6 from 76 ratings.
- Free tier
- Yes, free to download with in-app purchases
- Paid from
- In-app purchases $12.99–$16.99/mo, a Pro Monthly at $24.99/mo, and $99.99–$199.99 annually, as of August 2026
Political-trading intelligence dashboard
TraderCongress
A web dashboard that puts congressional trades next to government contracts, lobbying reports, federal spending, Form 4 filings and dark-pool signals.
- Best for
- Joining datasets that usually live apart. Congressional disclosures on their own tell you what a member bought. TraderCongress puts 109,800+ of those beside 13,200+ government contract awards and 20,000+ lobbying reports, which is the combination that makes a trade interesting rather than just visible. StockPlus does not carry contracts or lobbying data at all.
- Free tier
- Yes, congress trades and contracts on a 60-day delay, 3 watchlist slots
- Paid from
- Pro at $99.99/yr, shown as $8.33/mo, against a stated list price of $49/mo, as of August 2026
Options flow and smart-money analytics platform
InsiderFinance
A trading analytics platform built on real-time options order flow and dark-pool prints, with congressional and insider trade tracking alongside.
- Best for
- Order flow, and speed. Real-time options flow, dark-pool prints and intermarket sweep detection are the product, and they are datasets StockPlus does not carry at all. If you trade options intraday and want to see where size is going as it goes, this is a different category of tool and it is aimed at you, not at us.
- Free tier
- Yes, a free options-flow dashboard limited to the 15 most recent trades on a 30-minute delay, plus a free newsletter
- Paid from
- $75/mo, $195 per quarter, or $660/yr, as of August 2026, with the same features on every tier
Social investing app
Blossom
A social investing app where members link real portfolios and publish what they actually hold, wrapped around dividend and ETF tracking and a learning feed.
- Best for
- Community, and the transparency behind it. Blossom members publish real portfolios rather than opinions, which is a genuinely different thing from an analyst rating — Apple named it a Top 25 App of 2025, and it carries 4.8 stars across 2.9K ratings with over 500,000 investors. StockPlus has no social layer at all and is not trying to build one.
- Free tier
- Yes — free to use, with in-app purchases
- Paid from
- PRO $8.99/mo or $59.99/yr; Pro Plus $19.99/mo or $119.99/yr, as of August 2026
Research and analytics terminal
Koyfin
A web research terminal aimed at serious investors and financial advisors — charting, dashboards, financials, estimates and portfolio analytics in one workspace.
- Best for
- Depth of research workspace. Ten years of financials and estimates, ETF holdings, custom formulas and financial templates, macro dashboards, and advisor tooling with client reporting and custodian integration. It is a genuine Bloomberg-alternative workflow for people who do this professionally, and StockPlus does not attempt any of it.
- Free tier
- Yes — 2 watchlists, 2 screens and 2 custom dashboards, with 2Y financials
- Paid from
- Plus $39/mo, Premium $79/mo, Advisor Core $209/mo, with an annual plan stated to save up to 30%, as of August 2026
Multi-market insider transaction screener
Insider Screener
A screener for insider transactions across 16 markets, taken from national regulators and exchanges rather than from SEC EDGAR alone.
- Best for
- Geography, and it is not close. 16 markets: the US and Canada, Germany, France, Spain, Italy, Switzerland, the UK, Belgium, the Netherlands, Sweden, Finland, Denmark and Greece, plus India and Australia in beta, all normalised into one schema. If you hold European or Indian equities, StockPlus cannot show you insider filings on them and Insider Screener can.
- Free tier
- Latest trades and basic screeners are browsable; watchlists, exports and alerts sit behind a plan
- Paid from
- Three tiers, Plus, Pro and Premium, monthly or annual with three months free on annual and a 14-day money-back guarantee. The figures render client-side and were not present in the page source on 27 August 2026, so no price is quoted here

Questions people ask
What is the best SECForm4.com alternative with a mobile app?
StockPlus carries insider filings and 13F holdings on iOS and Android, with the feed on the free tier and Pro at $2.99/mo. StockInsider covers Form 4 and 13F too, through in-app purchases from $12.99/mo. Neither goes as deep on 13D and 13G filings.
Is there a free alternative for insider trading data?
Yes, and there should be, because Form 4 filings are public on SEC EDGAR. OpenInsider and Finviz both publish insider transactions free, and StockPlus includes an insider feed in its free tier. You should not pay much for data the SEC gives away.
Which alternative covers insider filings outside the US?
Insider Screener is the one built for that, covering 16 markets across the Americas, Europe and Asia-Pacific from local regulators and exchanges. SECForm4.com, StockPlus and most US tools are EDGAR-only.
