Vector tile rendering and labeling for Leaflet.
This project is a complete web map renderer - including quality label layout, pattern fills, and icons - in as simple as possible of an implementation. It's an alternative to renderers like MapLibre GL JS in a fraction of the size.
- Render interactive slippy maps with Leaflet integration
- Supports variable web fonts with multiple weights and italics in a single font file
- Can read normal Z/X/Y tile URLs or offline, static-hosted tile archives in PMTiles format
- Full out-of-the-box support for right-to-left and Indic/Brahmic writing systems
- Configurable via plain JavaScript
- Extensible API for defining your own symbolizers

The design is still evolving rapidly, so do not expect any kind of stable internal or external-facing API between minor versions. But please do report bugs and discuss requirements in the Issues.
