JOSM – Java OpenStreetMap Editor


  • Upcoming changes
    • OpenStreetMap is deprecating Basic Authentication and OAuth 1.0a. JOSM will be removing OAuth 1.0a support in early 2024, and may hide or remove Basic Authentication support at the same time. We recommend that all new users use OAuth 2.0 and existing users switch to it. See #22810 and the OpenStreetMap Operations ticket #867 for further details.
