Our take
The bottom line
QuickFS and The Fly Pro cover a lot of the same ground (3 shared categories, financials, data visualizations, and APIs & data feeds), so for the basics you won't go far wrong with either. The Fly Pro simply does more: 13 categories to QuickFS's 4, including screeners, stock comparison, and watchlist. QuickFS counters by keeping things simpler.

Where each one shines
What QuickFS and The Fly Pro each do best.What QuickFS does best
- Official homepage says QuickFS will not relaunch and that the founder introduced FastFS.org to a data vendor that could support a successor with major QuickFS-like features.
- Legacy product offered 20-year history for 200+ standardized metrics and statements across 40,000+ international stocks.
- Legacy Excel add-in used =QFS("ticker","metric","period") to pull data directly into models; Microsoft AppSource listings may still exist but require a QuickFS account and should not be treated as an active standalone service.
- Legacy API and exports covered fundamentals, market data, company metadata, CSV/Excel exports, and bulk downloads; current official homepage does not advertise active API access.
- Ticker format with country suffix (e.g., AAPL:US) and global coverage across U.S., Canada, Europe, Australia, and more were legacy capabilities.
What The Fly Pro does best
- Build company dashboards and financial charts.
- Screen stocks and ETFs with fundamental and performance filters.
- Research more than 10,000 business metrics and KPIs on Premium and higher plans.
- Review 10 years of financial data on Free and Premium or up to 30 years on Ultimate.
- Compare company operating metrics and financial data.

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 Pricing, features, and availability may be incomplete or out of date.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