    Our take

    The bottom line

    OpenInsider and ORTEX cover a lot of the same ground (3 shared categories, insider data, screeners, and data visualizations), so for the basics you won't go far wrong with either. ORTEX simply does more: 16 categories to OpenInsider's 3, including short interest, quant, and index rebalancing, plus a mobile app. OpenInsider counters by being completely free.

    Curation & Accuracy

    This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).

    Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
