Kakeru is built on the shoulders of great research, open-source software, and world-class APIs.
Research & Algorithms
Leon Powałka (2023). "Shape-guided Artistic Route Finding."
Kakeru's per-segment routing, shape-fidelity scoring (RTMV metric), and Douglas-Peucker simplification are informed by this research. Adapted for real-time web use via the Mapbox Map Matching and Directions APIs, extended with scale-adaptive Douglas-Peucker simplification and text-route generation.
Maps & Routing
Mapbox — Mapbox GL JS, Map Matching API, Directions API, Geocoding API, Static Images API, Tilequery (terrain & streets)
OpenStreetMap contributors — Road, path, and trail data underlying Mapbox's network. Off-road snapping uses community-mapped paths and trails.
Activity Sync
Strava — Authentication & route creation
Shapes & Icons
The Noun Project — Preset shape library sourced from community-contributed SVG icons
AI Shape Generation
Anthropic Claude — AI-powered shape generation from natural language descriptions. No personal data is sent in AI requests.
