Heatmapy — Strava Heatmap for Mapy.com per Matej Cermak

Plan routes on Mapy.com with Strava's heat on top of the map.

• Global heatmap by sport: switch between Road, MTB, Gravel, Run and Trail Run.
• Your personal heatmap in blue on top of the global heat. Each layer turns on and off on its own, so the roads and trails you haven't done yet stand out.
• Follows the map live: the heat moves with every pan, zoom and rotation.
• Sync to Strava: save your planned Mapy.com route to your Strava account in one click, as a private, starred route. From there it syncs to your Garmin or Wahoo. Or download a plain GPX file (no account needed).
• On-map panel with opacity, a minimize button and keyboard shortcuts (A all, S sport, D global, F personal), plus fast tile caching.

You need to be logged in to Strava in Firefox. A Strava subscription is needed for the global heatmap above zoom 11, your personal heatmap and Sync to Strava. Route planning and the plain GPX download work on a free account.

Firefox asks for access to strava.com when you install. If you turn that off later, click the Heatmapy toolbar icon and use Grant access, because the heatmap can't load without it.

The extension only talks to Strava, using your existing login, and keeps its settings on your computer. Nothing is sent to the developer or anyone else.
