I built this after a road trip where I kept second-guessing whether I could reach the next charger. Every tool I found either required a login, showed only official range numbers (which are optimistic), or didn't show chargers on the same map as the range estimate. The core question I wanted to answer in one tap: can I get there AND back without charging? The two-circle approach came from that — outer circle for one-way, inner for round-trip. If your destination is inside the inner circle, you're good. Simple visual, no math required. The car catalog was trickier than expected. Official specs vary by market, trim, and year — and go stale fast. So I built a Python pipeline that pulls from fueleconomy.gov, government EV databases, and region-native sources, runs anti-regression checks, and auto-syncs every 12 hours via GitHub Actions. 700+ presets across 20+ markets now, with a canary→stable promotion flow so bad syncs don't ship silently. Stack is deliberately boring: vanilla JS, Leaflet, no build step. Charger data merges OpenChargeMap and OpenStreetMap Overpass with deduplication. The whole thing runs as a static site on Vercel. Happy to answer questions on the range model, the catalog pipeline, or charger data quality in specific regions.
