Where each one shines
What QuickFS and Similarweb 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 Similarweb does best
- Analysis of website traffic, engagement, channels, keyword demand, referral sources, competitors, company profiles, technologies, and app intelligence where plan access allows.
- Free public tools for high-level samples such as traffic checks, app analytics, keyword tools, top websites or apps, and company or technology profiles.
- Similarweb API V5 in REST or Batch mode with API-key authentication, standardized responses, multi-metric requests, MCP and AI support, and one key across endpoint families.
- Subscriptions to daily or monthly release notifications through webhooks where API workflow access is available.
- Export support for data through no-code Data Exporter, scheduled email delivery, CSV downloads, dashboards, tables, Excel, PDF, PPT, and PNG formats depending on product access.

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 Pricing, features, and availability may be incomplete or out of date.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