Thunderforest Global Maps Services

• Commercial use is permitted and encouraged.
• All maps are provided under a Creative Commons licence, specifically CC-BY-SA 2.0.
• Map data from OpenStreetMap is licensed under the ODbL. You must be aware of the details.
• Tiles may be cached in-browser and on-device for offline use.
• Apps may retain tiles beyond the HTTP Expiry date, until fresh tiles are downloaded.
• Caching proxies or other redistribution methods are not permitted.
• Absolutely no bulk-downloading scraping, pre-downloading, pre-caching or anything similar. If you need the ability to do this, you’ll need prior written agreement and an appropriate service plan. Please see further details about Bulk Downloads, below.
• If your application or site puts too great a load on the servers, then we will discuss other approaches. If you are unsure, please get in touch.

High Traffic Services

Some sites and applications prove to be extremely popular, sometimes unexpectedly. If this turns out to be the case for you, then we will get in touch and ask you to upgrade to an appropriate service plan.

If you experience a sudden surge of traffic on a small project, the last thing you want is to be landed with an unexpected bill. We won’t charge you for a short-term traffic surge - instead, we can temporarily throttle traffic to avoid you going over your quota. If you’d rather pay for all surge traffic and ensure a constant service during unexpected events, then please get in touch.

Bulk Downloads

It’s a popular feature on many mobile applications to provide the ability to pre-cache or bulk download areas of the map - your customers can do this from the comfort of their own home, and avoid roaming charges and delays on slower connections. However, the number of requests generated by even a small number of users is significant, and so this is not permitted on the Hobby Project or Solo Developer service plans.

Please don’t perform any bulk downloads without an appropriate service plan - if you do, we reserve the right to block or restrict your account without warning.

If you wish to make bulk downloads, please upgrade your account to the Small Business plan or higher.
