Software dependencies
Mantle Place stands on a deep stack of open-source software. The list below covers the top-level production dependencies whose licenses require attribution. Transitive dependencies inherit attribution through their parents. Source code for each project lives at the linked repository.
- CesiumJS · Apache-2.0. WGS84 globe + 3D Tiles + quantized-mesh terrain rendering in the curator viewport.
- Next.js · MIT. React framework, App Router, server components, route handlers.
- React · MIT. Component runtime.
- Tailwind CSS · MIT. Utility-first styling.
- Radix UI primitives (via Base UI) · MIT. Accessible dialog / popover / menu primitives.
- PMTiles · BSD-3-Clause. Range-byte vector + raster tile archive format for the sovereign basemap.
- pmtiles JavaScript library · BSD-3-Clause. Browser-side PMTiles range fetching + decoding.
- Mapbox Vector Tile spec / parser · BSD-3-Clause. MVT decode used by the in-house basemap renderer.
- Turf.js · MIT. AOI area + geometry helpers.
- Supabase JS / SSR clients · MIT. Auth + Postgres + Realtime client.
- Stripe SDK + Elements · MIT. PaymentIntent + Elements checkout + webhook signature verification.
- TanStack Query · MIT. Async-state caching for curator + vault data loads.
- Zustand · MIT. Curator widget state store.
- Zod · MIT. Runtime validation of Supabase writes + PostHog events.
