* '''Keep Right'''{{VisAnchor|Keep Right}} <p>[[Keep Right]] ([http://keepright.at/ keepright.at]) shows a large number of automatically detected potential errors on a map or in list form. It has a system for reporting false positives and for labelling a bug as fixed. It has rules to automatically detect the following error types: non-closed areas, dead-ended one-ways, almost junctions, deprecated tags, missing tags, bridges/tunnels without layer (careful - not always an error), motorways without ref, places of worship without religion, POIs without name, ways without nodes, floating islands, un-tagged railway crossings, wrongly-used railway crossing tag, objects with {{key|FIXME}} tags, and relations without type. ''Keep Right'' shows tens of thousands of errors, including many that have little impact (e.g. a stream intersecting a highway: technically a bridge is needed here, but existing renders assume the stream is in a culvert).</p><!--

** This tool also generates half-transparent coloured layers showing administrative areas by admin_level, as well as other "political" areas (used in France for mapping electoral subdivisions, as well as intercommunal structures of cooperation that do not fit the hierarchy of admin levels, but used as well in other countries for similar non hierarchical administrative, judiciary and electoral boundaries). These coloured layers allow searching easily for missing/broken/incomplete/unclosed boundaries as well as overlapping/duplicate boundaries of the same type, or boundaries that are not tagged correctly to be found by querying the OSM database with simple filters (for example missing tag "boundary=administrative", missing or incorrect value in "admin_level=*").
