InsiderWatch vs OpenInsider
Looking for a OpenInsider alternative, or deciding between the two? Here is what each one is, what it costs, and what it does that the other does not.
| InsiderWatch | OpenInsider | |
|---|---|---|
| What it is | Research workspace: company pages, insider, Congress and fund disclosures with original source links, AI analysis, alerts and AI connections | Free SEC Form 4 screener: tables of insider buys and sells, updated as filings post |
| Price | $15 a month, 7-day free trial | Free; no paid tier or account found on the site |
| Coverage | SEC Form 4 insider buys and sells, 13D/13G activist stakes, 13F books of about 20 named funds, House STOCK Act trades, DoD contract awards, FDA decisions and advisory-committee documents, FTC/DOJ enforcement, Federal Reserve, Federal Register, lobbying, White House and Truth Social, market wires and per-ticker news | Form 4 insider trades only: latest filings, cluster buys, officer and CEO/CFO purchases, top buys and sales by day, week and month, a screener and charts |
| Alerts delivered to you | Email and Telegram, usually within minutes (routine insider buys can be held up to 45 minutes in a digest) | None: no email, push or other notification found on the site |

What OpenInsider has that we do not
- Free, instant access to every Form 4 as it files, with screens and filters you can set yourself
- Historical tables by day, week and month, and a cluster-buy view
What we have that OpenInsider does not
- Context around each filing: price chart, financials, earnings dates and related disclosures on one company page, with AI analysis that links to the original source
- Alerts: the buy that matters usually reaches your inbox and Telegram within minutes (routine buys can be held up to 45 minutes in a digest), instead of you checking a table
- A deterministic quality gate on insider alerts (open-market only, $50,000 floor, cluster and first-buy-in-years context)
- Coverage well beyond Form 4: activist stakes, fund books, Congress, FDA, DoD, enforcement and policy
Our Read
Which One Should You Use?
OpenInsider is the reference free Form 4 screener and we use the same SEC feed it does. If you are happy to check a table a few times a day, it costs nothing and does the job. InsiderWatch is for the person who wants the filing in context: the same feed filtered to the buys that clear a bar, placed next to the company's price, financials and ownership, linked back to the original filing, with an alert when it lands. It also watches a lot that OpenInsider does not: activists, funds, Congress and the government feeds.

Fair Questions
Is there an OpenInsider alternative that sends alerts?
InsiderWatch does: insider buys that clear a deterministic quality bar are emailed and sent to Telegram, usually within minutes, and land in a research workspace with their context, at $15 a month. The free Form 4 feed on our insider buying page stays open to everyone.
