MapLibre is a community-driven, open-source fork of Mapbox GL JS, offering a fully free and vendor-independent mapping library for web and mobile applications. It maintains close compatibility with the Mapbox Style Specification, meaning most existing Mapbox styles (pre-Standard) and workflows can migrate with minimal friction.
Maputnik is the visual style editor built for MapLibre (and the broader Mapbox GL ecosystem), allowing developers and designers to create, edit, and export map styles through a browser-based GUI. Together, they form a powerful open-source stack that eliminates licensing costs and API key dependencies while preserving professional-grade cartographic control.
For teams building mapping applications who want to avoid vendor lock-in, this duo represents a compelling, production-ready alternative to closed platforms. Please join us on April 22nd for an evening of maps, tools, and discussion with the local geospatial community.
About the speaker: Rafa Gutierrez is a 10 year alum from Mapbox and long time open source advocate. He will be sharing his experience with MapLibre and Maputnik and how he uses them in his work.
