Tláloc
Will it rain in Mexico City? Tláloc shows whether it's raining now, whether it's on the way, and how much to expect across a handful of CDMX landmarks (plus a few in London) — on an animated 3D WebGL city map, plus a list view with a looping 24-hour rain radar. Under the hood it's a single free Cloudflare Worker: a Hono API that caches Open-Meteo forecasts in KV and refreshes them on a cron, serving a Vite + deck.gl frontend from the same origin. A 2026 rebuild of a 2021 iOS app, with Claude Code.
