TiTiler is a set of Python packages for building dynamic raster map tile services on top of FastAPI and Rasterio/GDAL. It serves tiles from Cloud Optimized GeoTIFFs, STAC items, Zarr datasets, and MosaicJSON virtual mosaics with support for multiple projections and OGC tile APIs.

Use cases

• serve map tiles from cloud optimized geotiffs
• build a dynamic raster tile server for web maps
• create tile endpoints for STAC satellite imagery
• serve virtual mosaics from mosaic
• deploy a serverless tile API on AWS Lambda
• render zarr or netcdf multidimensional datasets as tiles
• support multiple tile matrix sets and projections in a tile service

When to choose

• you need on-the-fly map tiles from COGs, STAC, or Zarr without pre-generating tiles
• you want a customizable FastAPI-based tiling service deployable to Lambda, ECS, or Kubernetes
• you need OGC Tiles/WMTS API compliance and multiple projections

When to avoid

• you only need to serve pre-rendered static tiles from a file server
• your data is vector rather than raster
• you want a turnkey GIS server with full WMS/WFS support rather than a tiling framework
