Feature-by-feature
Where HoldingsIntel gives you more
HoldingsIntel treats every insider buy as evidence to corroborate. Its Alignment view finds stocks where Form 4 buying and accumulation by the 551 largest institutional managers land in the same quarter, then weighs both against activist and congressional filings. OpenInsider provides more granular standalone Form 4 filtering; HoldingsIntel answers the more useful investment question: who else agrees?

OpenInsider
Free
OpenInsider's public Form 4 screener is free to use.
An insider buy is one witness
A CEO writing a personal check for company stock is testimony worth hearing — insiders know things. But one witness can be wrong, early, or simply rebalancing. The buys that deserve the most attention are corroborated ones: the same quarter the CFO bought, disciplined funds were adding, or an activist crossed 5%. OpenInsider gives you the first witness in full detail — the others file different forms, outside its scope. HoldingsIntel's Alignment view runs the corroboration automatically — every stock where Form 4 buying and institutional accumulation landed together — and the per-stock verdict adds activist and congressional filings to the record.
The narrow exception
Choose OpenInsider only when its strengths matter more
OpenInsider may fit when a free, highly filterable Form 4 screener is the entire requirement. HoldingsIntel is the better choice when an insider buy needs independent corroboration.
Bottom line
For serious holdings research, choose HoldingsIntel
Choose HoldingsIntel to corroborate insider buys against institutional accumulation, activist stakes, and congressional trades in web, REST API, or MCP workflows.

Questions investors ask
Can HoldingsIntel replace OpenInsider as an insider-trading screener?
HoldingsIntel does not reproduce every OpenInsider filter or prebuilt view. It covers the same Form 4 filings for a different job: putting each buy next to the institutional, activist, and congressional record on the same stock.
What is HoldingsIntel's Alignment view, and does OpenInsider offer anything like it?
Alignment surfaces stocks where insider buying and institutional accumulation landed in the same quarter — two independent groups with disclosure obligations moving the same direction. OpenInsider doesn't attempt it, because it would need the 13F dataset, which sits outside a Form 4 screener's scope. It is the main thing you'd come here for that a free insider tool can't do.
OpenInsider is free — what am I paying HoldingsIntel for?
The corroboration layer, not the insider data. Form 4 filings are public and free everywhere, including here. The paid tiers ($19–49/mo) buy the 13F engine around them: conviction ratings on 551 managers' positions, the Alignment view, multi-quarter history, and the four-source verdict per stock.
