I'm using Leaflet for the maps of my website. So far I was using maps of Mapbox (they're cool), but they obviously charge for them for website with 100,000+ maps per month.
I'm trying to find a provider of tiles which no charge for their tiles. Initially, I do it with OpenCycleMap, and substituted
1) Does OpenCycleMap provide free tiles with no restriction of maps per month?
2) Does anybody know any other free provider?
