- 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.
