Quick answer: Do not use official OpenStreetMap tiles for a mainland China product. OSM itself is not fully blocked, but the default tile servers (*.tile.openstreetmap.org) are extremely unstable from mainland networks — failed loads, timeouts, and very slow tiles are common. For China-facing users, prefer Amap, Tencent Maps, Tianditu. Availability in China: Limited.

OpenStreetMap is Limited for mainland China production maps. The project is reachable in principle, but Chinaready does not recommend depending on OSM's official online tile service for a China-facing app or website. Three constraints matter more than the “is it blocked?” question:
If the product and users are in mainland China, switch to a compliant, in-country tile or SDK path rather than OSM's official CDN:
| Option | Why teams pick it | Access |
|---|---|---|
| Amap (高德地图) | Mainstream China maps with fast mainland loading — a practical default for web and App tiles | Public raster tile URLs are commonly used for quick Leaflet-style integration without registering a key; keyed APIs remain available on the developer platform |
| Tencent Maps (腾讯地图) | Stable domestic tiles and strong mainland access — a close second to Amap for web maps | Likewise offers free raster tiles that teams often use without a key, plus keyed LBS APIs |
| Tianditu (天地图) | Official national basemap from the National Geomatics Center of China — strongest compliance story | Register a free account and use the issued Key |
Teams that need OSM's open data under their own control can download the extract, then serve tiles from a mainland private host with tools such as TileServer-GL. That removes the overseas-tile network problem. Publishing those tiles as a China map service still requires the relevant surveying and mapping qualifications and a map review number — self-hosting is not a shortcut around 测绘法.
For China-facing products, drop OSM's official online tile service. Prefer Amap, Tencent Maps, or Tianditu so loading, coordinates, and map-review compliance stay in-country.
Tencent Maps and Tianditu appear on this alternatives page as orientation options — Chinaready does not add them as Explore / Landscape product tiles from this rewrite. Confirm tile terms, keys, GCJ-02 handling, and map-review requirements before production adoption.
Mapped China-ready candidates
Amap (高德地图) is the mainstream China map stack with fast mainland loading. Public raster tile URLs are commonly used for quick Leaflet-style integration without registering a key; keyed APIs remain on the developer platform. Primary OSM-tile substitute for China-facing web and App maps.
Tencent Maps (腾讯地图) offers stable, fast mainland raster tiles that teams often use without a key for basic web maps, plus keyed LBS APIs. A close second to Amap when the product already sits in the Tencent ecosystem.
Tianditu (天地图) is the official national basemap from the National Geomatics Center of China — the strongest compliance-oriented OSM substitute. Register a free account to obtain a Key before serving tiles.
Not as a production default. Chinaready labels OpenStreetMap as Limited. OSM itself is not fully blocked, but official tile servers (*.tile.openstreetmap.org) are extremely unstable from mainland China — failed loads, timeouts, and very slow tiles are common. Do not point China-facing maps at OSM's official CDN.
Three reasons: official servers are overseas so tiles often fail to load; China's Surveying and Mapping Law requires a map-service qualification and a map review number (审图号), so an unreviewed foreign basemap is a compliance risk; and OSM uses WGS-84 while mainland maps require GCJ-02, which can offset points by hundreds of meters.
Chinaready currently lists these China-market options for OpenStreetMap: Amap, Tencent Maps, Tianditu. Prefer Amap (高德地图) or Tencent Maps (腾讯地图) for fast domestic raster tiles, and Tianditu (天地图) when official national-basemap compliance matters most. Confirm tile terms and keys before shipping.
Yes as an advanced path. Download OSM data and serve tiles from a mainland host with tools such as TileServer-GL to avoid overseas tile outages. If you publish those tiles as a China map service, you still need the relevant surveying and mapping qualifications and a map review number — self-hosting does not by itself satisfy 测绘法.
Pick a domestic tile or SDK path, convert coordinates to GCJ-02, and confirm map-review / qualification requirements before launch. Use the interactive Chinaready Landscape for adjacent stack choices, then read Chinaready's main site for launch operating guidance. If the path remains unclear, book a call with Chinaready.
