OpenStreetMap
In the last month I developed two tools for inspecting osm data.
First tool is the Restriction Analyser. It checks (syntax and directions) of turn-based restrictions and visualize them on OSM.
Note: At the moment it can't handle restrictions with more or less than one via nodes.

Second tool is the OSM History Browser. It allows you to browse the history (like history in the wiki) of each node, way or relation and to see the difference between two versions of the object (like the diff in the wiki).
Note: you have to put in an id of the node way or relation.
Example: http://osm.virtuelle-loipe.de/history/?type=relation&ref=33333

Very useful! Your tool very nice to check turn-based restrictions. I am able to see the locally available restrictions and can see where restrictions are missing. Then I can add them or give hints to others.

Es wäre genial, wenn man mit dem Tool auch gleich Hinweise in Openstreetbugs eingeben könnte. Dann müsste man nicht extra einen zweiten Tab oder ein zweites Browserfenster für Openstreetbugs öffnen.

Great tool! Thank you very much. I've just discovered restriction relations and your tool has helped greatly. It's also nice to see the road signs rendered. Would be nice to have UK symbols for the UK ;-)
