The route and the coastline

These come from open government data:

• King Charles III England Coast Path Route — Natural England
• National Trails (England) — Natural England
• Published stretch lengths, for sections not yet mapped — Natural England (gov.uk)
• Place-name coordinates for the chart's towns, harbours and headlands — OS Open Names, Ordnance Survey

All three are used under the Open Government Licence v3.0, which asks for this line:

There are no third-party map tiles. The chart is drawn from the route geometry itself, so nothing is fetched from a map provider as you use it.
