OSM MultiToolz

Analyze OpenStreetMap changesets with quick links to various QA tools and a personal OSM watchlist.

OSM Multi Toolz is a powerful Chrome extension for OpenStreetMap contributors and data enthusiasts. Quickly analyze changesets and mapper activity directly from your browser with comprehensive tools and instant access to OSM services. Advanced Changeset Analysis: - Automatic detection from OSM changeset, node, way, and relation pages - Detailed user analytics: changeset count, account age, last edit date, GPS traces - Complete changeset metadata: comments (with translation), editor, bounding box, dates - Smart alerts for large areas, old changesets, and unusual activity patterns New in Version 2.0: Deleted Objects Viewer List ways and standalone nodes deleted in the selected changeset. Open an object in a map tab showing its last available visible version before deletion, with all its tags. Recover historical node positions and display warnings when geometry is incomplete. Keep the list readable by hiding nodes belonging to the listed ways. The viewer is read-only. It does not restore or modify OpenStreetMap data. The background map shows current OSM data; highlighted objects show their historical geometry. Deleted relations are not supported yet. One-Click OSM Tools Quickly open the selected changeset, map area, tags or relations in widely used OpenStreetMap services that are essential to many contributors’ workflows for visualizing edits, checking data quality, comparing maps and investigating mapping issues. Additional Features Personal watchlist with JSON import and export. Tag analysis with grouping by key, prefix or object type, plus occurrence counts. Lists of created and modified relations with links to external analysis. English, Italian and Slovak interfaces, selected according to your browser language. Privacy Focused: Only accesses public OpenStreetMap data. No personal information stored or shared. Perfect for mappers, data validators, community managers, and anyone passionate about OpenStreetMap data quality!
