OSM QA Tiles are now available as country extracts, updated daily! Country extracts are smaller sized and focused, making it easier for anyone to run their own local analysis. We have been using OSM QA Tiles along with TileReduce to examine OpenStreetMap coverage, understand cities through street names and improve sidewalk data.

The extracts are generated using our open source mbtiles utility that Vladimir and I put together. You can download the country extracts here. Hit me up on Twitter if you have any questions.
