OS OpenSpace for web applicationsimage to show the OS openSpace pins logo

OS OpenSpace is a free service that allows you to embed our maps, covering the whole of Great Britain, into your web applications that are free to consumers. OS OpenSpace uses our JavaScript application programming interface (API) and does not include any advertising in the maps.

There are limits to the free service, so if you are expecting your application to have a high volume of traffic, then you may wish to use OS OpenSpace Pro, which provides additional mapping layers, technical support and a service-level agreement.

Step 1:

To get started with OS OpenSpace, you’ll need to register for a Developer Account.
