NyckelBot

NyckelBot is the crawler behind Nyckel, a property-search workbench for Stockholm. It reads public listing pages on real-estate broker websites so home buyers can search every home for sale in one place. Every listing links back to the broker's own page.

How it behaves

  • Identifies itself as NyckelBot/<version> (+https://nyckel.site/bot; jim@instabox.se).
  • Reads and honours robots.txt; disallowed paths are never fetched.
  • At most one request per second per site, on a single connection.
  • Uses conditional requests so unchanged pages are not downloaded again.
  • Stops for six hours on any 403, 429 or block page, and alerts us.
  • Only public listing pages: no logins, no forms, no personal data beyond what the listing shows.

To opt out

Add User-agent: NyckelBot followed by Disallow: / to your robots.txt. We re-read it before every crawl and stop on the next pass. You can also email jim@instabox.se and we will stop within one business day.
