Thunderforest provides carefully curated global maps for web and mobile app developers, with an emphasis on reliable data, thoughtful detail, and straightforward integration. Its map styles serve a range of needs, including cycling, public transport, outdoor activities, natural landscapes, and general navigation. Options include OpenCycleMap, Transport, Landscape, Outdoors, Atlas, and a dark Transport style. Labels are available in local languages and English to help users find relevant information.

Developers can use ready-made styles, overlay their own data, or commission custom cartography. Custom work can include branding, tailored icons, and highlighting or removing specific map features, as well as adapting existing Thunderforest styles or migrating another map style. The service offers the Map Tiles, Static Maps, Vector Styles, and Vector Sources APIs, and supports a wide range of mapping libraries and development platforms, including JavaScript, Flutter, and native mobile toolkits. Access is through an API key, with documentation and tutorials provided. Thunderforest offers a free plan for testing and paid plans starting at $125 per month.
