Useful for

Use cases llm-inferred

Travel-time catchments (isochrones) around a site for accessibility or sustainable-transport appraisals · Route distance and duration between project sites for travel-time or site-access inputs · Self-hosted routing backend for workflows where external routing APIs are not acceptable

Audience llm-inferred

GIS analysts · transport planners · planners · developers building MCP-based tools

Limitations

Constraints llm-inferred

Only route and isochrone tools are supported; matrix, map-matching, elevation, locate, centroid and optimised routing are listed as coming soon · No elevation, flood, drainage or UK-specific datasets are offered · Public demo API is intended for testing; no rate limits or service levels are documented · Results depend on the Valhalla configuration and the OSM extract loaded; a local deployment needs Docker and an OSM build · Version 0.1.0 with no documented maintenance commitment · Catalogue licence field is null although the docs state MIT
