Fentner Business Spotlight

Installmap placed first of eleven website technology lookup tools in our comparison. This review goes through its detection, its two crawls and what an analyst can cite from it at no cost.

  • Detection — 294 fingerprints in 18 categories; a match means the code loads, not that the tool is paid for
  • Named lists — six groups rendered in a headless browser, including the Fortune 500 and YC
  • Wider sample — 8,291 company sites counted from 30,000 selected, with seventeen failure reasons
  • Recall gap — plain fetch found 36.7% of rendered installs on Inc 5000 domains
  • Minimum base — n/a below 20 crawled sites per cell
  • Price — free to read and cite
