We call this **speed mode**; without this CH preparation, we call it **flexible mode**.\n\nThe speed mode comes with very fast and lightweight (less RAM) responses, although it does not use heuristics \nin its default settings. The downsides are that the speed mode allows only pre-defined vehicle profiles (multiple possible in GraphHopper) \nand requires a time consuming and resource-intensive preparation. Finally, implementing certain features is not possible \nor very complex compared to the flexible mode. \n\nThe **hybrid mode** also requires preparation time and memory,\nbut it is much more flexible regarding changing properties per request or e.g. integrating traffic data and more. \nFurthermore, this hybrid mode is slower than the speed mode, but it is an \norder of magnitude faster than the flexible mode and uses also less RAM for one request.\n\nYou can switch between all modes at request time.\n\n## License\n\nWe chose the Apache License to make it easy for you to embed GraphHopper in your products, even closed source.\nWe suggest that you contribute back your changes, as GraphHopper evolves fast,\nbut of course this is not necessary.\n\n## OpenStreetMap Support\n\nOpenStreetMap is directly supported from GraphHopper. Without the amazing data from\nOpenStreetMap, GraphHopper wouldn't be possible at all.\nOther map data will need a custom import procedure, see e.g. Ordnance Survey,\nShapefile like ESRI or Navteq.\n\n## Written in Java\n\nGraphHopper is written in Java and runs on Linux, Mac OS X,\nWindows, BSD, Solaris, Raspberry Pi, Android, Blackberry, and even iOS.\n\n### Maven\n\nEmbed GraphHopper with OpenStreetMap support into your Java application via the following snippet:\n\n```xml\n\n com.graphhopper\n graphhopper-reader-osm\n [LATEST-VERSION]\n\n```\n\nIf you want to write your own import procedure or you don't need OSM import like\non [Android](./docs/android/index.md), then use:\n\n```xml\n\n com.graphhopper\n graphhopper-core\n [LATEST-VERSION]\n\n```\n\n## Customizable\n\nWe've built the GraphHopper class which makes simple things easy and complex things like multi-modal routing possible. \nStill, you can use the low level API of GraphHopper and you'll see that\nit was created to allow fast and memory efficient use of the underlying data structures and algorithms.\n\n### Android / Blackberry\n\nOn Android and Blackberry (since 10.2.1), we provide an integration with Mapsforge which makes offline navigation one step closer.\nDue to the usage of memory mapped files and Contraction Hierarchies,\nwe avoid allocating too much memory. This makes it possible to run Germany-wide queries with only \n32MB in a few seconds. We provide an Android studio project as well as the Maven-Android integration to be \nused in other IDEs.\n\n### Web UI and API\n\nWith the web module, we provide code to query GraphHopper over HTTP and decrease bandwidth usage as much as possible.\nFor that we use a polyline encoding from Google, the Ramer–Douglas–Peucker algorithm, and a simple \nGZIP servlet filter. \nOn the client side, we provide Java and JavaScript code (via Leaflet) to consume that service and \nvisualize the routes.\n\n### Desktop\n\nGraphHopper also runs on the Desktop in a Java application without internet access.\nE.g. you could use the rough user interface called MiniGraphUI provided in the tools module, see some\nvisualizations done with it [here](https://graphhopper.com/blog/2016/01/19/alternative-roads-to-rome/).\nA fast and production ready map visualization for the Desktop can be easily implemented via mapsforge.\n\n### Docker\n\nInstall GraphHopper via [Docker](https://github.com/graphhopper/graphhopper/pull/849).\nYou only need to change the docker-compose.yml entrypoint in core/files/ to run whatever map you like.\nThen just type:\n```bash\ncd core/files/\ndocker-compose up -d\n```\n\nIf you don't want to use docker-compose you can do the following:\n```bash\ndocker build -t graphhopper:master .\ndocker run -d --name graphhopper -v /data:/data -p 8989:8989 graphhopper:master\n```\n\n\n# Features\n\nHere is a list of the more detailed features including a link to the documentation:\n\n * [Quick installation and start for users](./docs/web/quickstart.md) - just Java necessary! [Simple start for developers](./docs/core/quickstart-from-source.md) due to Maven.\n * Works out of the box with OpenStreetMap (osm/xml and pbf) and can be adapted to custom data\n * OpenStreetMap integration: Takes care of the road type, speed limit, the surface, barriers, access restrictions, ferries, [conditional access restrictions](https://github.com/graphhopper/graphhopper/pull/621), ...\n * GraphHopper is fast. And with the so called \"Contraction Hierarchies\" it can be even faster (enabled by default).\n * Memory efficient data structures, algorithms and [the low and high level API](./docs/core/low-level-api.md) is tuned towards ease of use and efficiency\n * Provides a simple [web API](./docs/web/api-doc.md) including JavaScript and Java clients\n * Multiple weightings (fastest/shortest/...) and pre-built routing profiles: car, bike, racingbike, mountain bike, foot, motorcycle, ...\n * Support for public transit routing and [GTFS support](./reader-gtfs/README.md).\n * Offers turn instructions in more than 35 languages, contribute or improve [here](./docs/core/translations.md)\n * Displays and takes into account [elevation data](./docs/core/elevation.md) (per default disabled)\n * Can apply [real time changes to edge weights](https://graphhopper.com/blog/2015/04/08/visualize-and-handle-traffic-information-with-graphhopper-in-real-time-for-cologne-germany-koln/) (flexible and hybrid mode only)\n * Customize vehicle profiles per request (flexible and hybrid mode only)\n * Possibility to specify a [heading parameter](./docs/core/routing.md) of the vehicle for start, end and via points for navigation applications via `pass_through` or `heading` parameters (flexible and hybrid mode only)\n * [Alternative routes](https://discuss.graphhopper.com/t/alternative-routes/424) (flexible and hybrid mode only)\n * [Turn costs and restrictions](./docs/core/turn-restrictions.md)\n * Country specific routing via SpatialRules\n * The core uses only a few dependencies (hppc, jts and slf4j)\n * Scales from small indoor-sized to world-wide-sized graphs\n * Find nearest point on street e.g. to get elevation or 'snap to road' or being used as spatial index (see [#1485](https://github.com/graphhopper/graphhopper/pull/1485))\n * Do [map matching](https://github.com/graphhopper/map-matching) with GraphHopper\n * Calculate [isochrones](./docs/web/api-doc.md#isochrone) with GraphHopper\n * Show path details [#1142](https://github.com/graphhopper/graphhopper/pull/1142)\n","has_starred","hub_user","immutable_tags_settings",{"_71":11,"_72":73},"enabled","rules",[74],".*","is_automated","permissions",{"_78":17,"_79":11,"_80":11},"read","write","admin","user","storage_size",351214907,"orgData","recentTags",[87],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":96,"_46":113,"_114":90,"_115":29,"_116":52,"_53":117,"_118":119,"_120":104,"_121":113,"_122":62,"_123":17},"content_type","creator",4122162,"full_size",351205382,"id",55280736,"images",[97],{"_98":99,"_100":101,"_102":44,"_103":104,"_105":106,"_107":108,"_109":44,"_110":-5,"_111":92,"_59":62,"_112":-5},"architecture","amd64","digest","sha256:07355bcf02628ba32d1cb885d2c7a36a86d4c08173ad9f76cdb7cf3b15c4965f","features","last_pulled","2026-09-23T08:27:37.958155287Z","last_pushed","2019-05-10T19:06:36Z","os","linux","os_features","os_version","size","variant","2019-05-10T19:06:35.155309Z","last_updater","last_updater_username","media_type","latest","repository",7100384,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","showSbxLogoOverride","sbxTrademarkText","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_34":135,"_142":143,"_131":152,"_153":11},{"_36":136,"_38":137,"_41":42,"_43":44,"_45":11,"_46":47,"_48":49,"_50":138,"_53":31,"_28":29,"_54":55,"_56":40,"_57":58,"_59":60,"_61":62,"_63":-5,"_64":58,"_65":66,"_67":11,"_68":29,"_69":139,"_75":11,"_76":141,"_81":29,"_82":83},[],[40],[52],{"_71":11,"_72":140},[74],{"_78":17,"_79":11,"_80":11},"tags",{"_144":60,"_145":-5,"_146":-5,"_147":148},"count","next","previous","results",[149],{"_88":40,"_89":90,"_91":92,"_93":94,"_95":150,"_46":113,"_114":90,"_115":29,"_116":52,"_53":117,"_118":119,"_120":104,"_121":113,"_122":62,"_123":17},[151],{"_98":99,"_100":101,"_102":44,"_103":104,"_105":106,"_107":108,"_109":44,"_110":-5,"_111":92,"_59":62,"_112":-5},[],"canDeleteTags","actionData","errors"]
