For operators of services the app uses

Requests from the app for search, places, routes and editing carry a User-Agent that starts with OpenMapSoftware/, for example:

OpenMapSoftware/0.1 (iOS; open source; EUPL-1.2; +https://openmapsoftware.org; contact@openmapsoftware.org)

If you run one of these services (for example Transitous, FOSSGIS / openstreetmap.de, komoot Photon, the OpenStreetMap API or a tile server) and the app causes too much load, breaks your usage policy or should change how it calls your service, please email contact@openmapsoftware.org. We will reply and change the app, or stop using the service, as needed.

What the operators ask

Each service has its own usage policy. Below is a short summary of what each operator asks of apps, and what they advise when an app causes too much load. Policies change: the linked page is always the one that counts. Summaries checked on 8 and 9 November 2026.

Transitous

Asks: Only free, open-source, non-commercial apps. Every request needs a User-Agent with app name, version and a contact (email or website). A visible link to the Transitous sources page.

Heavy use or problems: More than 720 route requests per 24 hours, many users or automated requests count as high load: contact the operators before scaling up (Matrix channel #transitous:matrix.spline.de). No scraping. Best effort; access may be stopped at any time.

Policy: transitous.org/api

FOSSGIS routing (Valhalla)

Asks: Attribution with a “fix the map” link, a valid User-Agent, at most one request per second.

Heavy use or problems: No scraping and no heavy use. Server administrators: fossgis-routing-server@openstreetmap.de.

Policy: routing.openstreetmap.de/about (full terms in German on fossgis.de)

Overpass API (FOSSGIS)

Asks: A User-Agent that identifies the app. Cache and limit requests; no parallel requests. For regular use, all users of an app together should stay around 100 queries and 10 MB per day.

Heavy use or problems: After HTTP 429 or 406, wait 30 seconds before retrying. Heavy and commercial users should run their own server or use a commercial provider.

Policy: OSM wiki: Overpass API

Photon (komoot)

Asks: Fair use.

Heavy use or problems: Extensive use is throttled; no availability guarantee. Photon is open source and can be self-hosted.

Policy: photon.komoot.io

OpenStreetMap API (editing)

Asks: The editing API is for editing, not for read-only use. A valid User-Agent with app name and version; licence attribution; at most 2 download threads.

Heavy use or problems: Large or frequent readers should use planet.osm downloads or Overpass, and talk to the system administrators first. Clients that disturb the service may be blocked without notice.

Policy: OSM API Usage Policy

OpenStreetMap tiles

Asks: A distinct User-Agent, visible OSM attribution, respect the caching headers. Only tiles the user is viewing: no bulk or offline downloads.

Heavy use or problems: Access may be blocked without notice. Heavy users should switch to another tile provider or run their own tile server.

Policy: OSM Tile Usage Policy

OpenFreeMap

Asks: A unique User-Agent. No scraping; offline downloads at most 3,000 tiles or 50 MB, 4 parallel requests.

Heavy use or problems: Contact info@openfreemap.org before going beyond the limits. Can be self-hosted.

Policy: openfreemap.org/tos

OpenRailwayMap

Asks: A unique User-Agent. Free apps open to the public only; no bulk requests.

Heavy use or problems: On HTTP 429, stop requesting. Apps with heavy traffic should use a cache or their own server.

Map errors

The map data comes from OpenStreetMap, which anyone can improve. If something on the map is wrong or missing, you can fix the map yourself.
