CI Seed Map – Interactive US cannabis seed availability map with dual modes, logo markers, AWS auth, and 1k+ verified entries

Hey [ r/webdev ]( r/webdev )! I just open-sourced the frontend for a tool I built to solve a very real (and timely) problem in the cannabis space. With the 2025/2026 federal hemp law changes coming (seeds will no longer freely cross state lines), growers need to know exactly what genetics are available in their state. So I created CI Seed Map — a fully interactive, data-heavy map of 1,039 breeders, seed banks, dispensaries, and cultivators across 27+ states. Live demo: https://seed-map.poweredbyci.live Repo: https://github.com/Shannon-Goddard/seed-map-usa Key features I’m proud of: • Dual UI modes: Location mode (filter by type/state, marker clustering) + Breeder mode (searchable list of 924 unique breeders → show every location carrying them with custom logo markers). • Priority stacking — when a spot carries multiple selected breeders, the top one’s logo shows with a green ring + “+N” badge. • Rich popups with brand logo grids (up to 12 + “+more”), strain highlights, and hand-written editorial notes. • “Find Me” geolocation with branded radius circle, live search, mobile-first responsive design (collapsible filters, hamburger nav). • Age gate + strong data protection: AWS API Gateway + Lambda serving private S3 data via time-limited HMAC-SHA256 session tokens (no static JSON exposure). Tech stack: • Leaflet.js 1.9.4 + MarkerCluster • OpenStreetMap tiles • Vanilla JS + responsive CSS (mobile-first) • AWS Lambda (Python 3.12) + API Gateway + private S3 • 700+ processed brand logos, Nominatim geocoding pipeline, Formspree forms The dataset was manually researched and verified (huge shoutout to the data side), but the map itself was built lightning-fast with Amazon Q Developer helping on architecture, token system, responsive bits, etc. Would love any feedback on the UX, performance, code structure, or ideas for future enhancements (e.g. more advanced filtering, user submissions, etc.). Especially curious how the logo marker + priority logic feels! 🌱 (21+ only, obviou
