How InsiderPulse compares
The honest version, including what the alternatives do better. All of these tools read the same public filings — what differs is coverage, speed, and what each is willing to claim about the data.
| What | InsiderPulse | The field |
|---|---|---|
| Live SEC Form 4 feed | Streams from EDGAR within minutes, parsed and scored; grants and routine vesting separated from real open-market buys | OpenInsider screens Form 4s well; congressional trackers mostly don't cover insiders at all |
| Congressional trades | US House STOCK Act filings, dated, with filed ranges and links to every source PDF | Capitol Trades and Quiver cover Congress broadly — it's their core focus |
| Investor portfolios (13F) | 147 tracked managers with complete books — every position, weights and quarter-over-quarter changes | Most trackers show top holdings or headline changes only |
| Track records | Every current insider buyer scored on their own past filings, benchmarked against the S&P 500 | Rarely offered — most tools show the trade, not whether the trader has ever been right |
| The honesty stance | We ran the backtest: insider signals lag the S&P on their own, and the site says so. No alpha claims, everything dated to its filing | Varies — much of the category markets 'follow them to profits' framing the data doesn't support |
When OpenInsider is the right pick
You want a free, no-frills Form 4 screener with custom filters and don't need congressional trades, portfolios, track records or alerts. It has been the reference free screener for years, and if raw tables are all you need, use it — it costs nothing.
When Capitol Trades or Quiver is the right pick
You care only about Congress. Both cover congressional trading as their core product, and Capitol Trades is free. InsiderPulse covers the House STOCK Act feed too, but our depth is in combining it with the live insider tape and institutional books on one screen.
When Unusual Whales is the right pick
You trade options and want flow data. That is their center of gravity, and we don't compete on it. If your question is "what are insiders, institutions and Congress actually filing, dated and verifiable" rather than "what is the options tape doing", that's ours.
When InsiderPulse is the right pick
You want the whole disclosure picture in one place — the live Form 4 tape, congressional trades, full 13F books, planned sales before they happen, and insiders scored on their own record — from a product that tells you what the data cannot do as plainly as what it can. Free tier included; Pro is $45/mo.
Try the free tier and judge it yourself
The live tape, cluster signals and the most-bought board are free — no card, no trial clock. If it isn't obviously better for your question, use one of the tools above with our blessing.
