Maplibre is an open-source project that lets you create truly custom, interactive maps without any vendor lock-in. You control the data, styling, and hosting, often using familiar tools like MapLibre GL JS. It's great for developers who want a modern, performant map engine that respects user privacy and avoids proprietary APIs. The community keeps it robust with regular updates and a focus on standards.
