Freemap is a custom Mapnik-based OSM renderer which aims to provide output from OSM data with particular emphasis on countryside users and walkers. Due to resource limitations it's currently restricted to certain parts of England and Wales only (generally central southern England; Oxford/Cotswolds/Northamptonshire/Warwickshire; Staffordshire/Derbyshire/Cheshire; north Wales and Lancashire/Cumbria), though it could potentially be used anywhere. OSM data is rendered using custom Mapnik rules (to distinguish between official and permissive rights of way, for example) and overlaid on NASA SRTM contours.

It's not just an OSM renderer though. Users can add countryside-specific data on top of the maps, such as walking routes and annotations including location of blocked paths, nice views and even photos, through a link up with Geograph.

Future plans include development of a mobile client (J2ME based, for Nokia N95 and potentially GPS-enabled iPhones in the future)
