Our take
The bottom line
Calcbench and OpenBB cover a lot of the same ground (3 shared categories, financials, APIs & data feeds, and sheets / excel add-ins), so for the basics you won't go far wrong with either. OpenBB simply does more: 12 categories to Calcbench's 8, including data visualizations, custom dashboards, and AI research, plus a mobile app. Calcbench counters by keeping things simpler.

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 Pricing, features, and availability may be incomplete or out of date.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.
