WP Mapbox GL JS is a creation of Mapster Tech, a Vancouver-based software company that specializes in maps and front-end development. The plugin development was headed by Victor Temprano, and is ongoing. We are working on more advanced premium versions of the plugin, which will have extensive functionality around using WordPress posts for mapping data, importing data, and much more.
We welcome suggestions and fixes, and our ultimate goal is to make a great product that you find easy to use. That makes us feel great, and hopefully gets your map woes out of the way fast!
