RadrView — Open-Source Weather Radar

That is live radar data from multiple sources — ingested, normalized, and served entirely by RadrView. At lower zoom levels you see MRMS composite tiles (1 km, ~2 min updates). Zoom in to z8+ and RadrView switches to NEXRAD Level 2 direct station data at native 250 m resolution. Self-hosted. Open-source. No API keys. No vendor lock-in.

Features

Everything you need. Nothing you don't.

🌍

Multi-source global radar

MRMS (CONUS, Alaska, Hawaii), DWD Germany, Environment Canada, and NEXRAD Level 2 — unified in one tile feed.

🗺️

Standard XYZ tile protocol

Drop-in compatible with Leaflet, MapLibre GL, OpenLayers, and CesiumJS. One URL, every map library.

🐳

Docker-first deployment

docker compose up and you're live. No infrastructure expertise required.

🎨

6 color palettes

Dark, NOAA, Viridis, Plasma, colorblind-safe, and precip-type palettes. Switchable at request time.

⚡

WebSocket live updates

Real-time frame push the moment new radar data is ingested. No polling required.

💾

MBTiles storage

Tiles stored in MBTiles with a pluggable TileStore backend. Swap storage without changing the API.

📡

NEXRAD Level 2 · 250m

At zoom 8+, RadrView switches to direct WSR-88D station data from 159 NEXRAD sites at native 250 m gate spacing — no upscaling needed.

🔄

Real-time sweep display

For stations with live chunk data, a rotating sweep line and progressive 60° wedge render on a Canvas overlay as each radial arrives.

📊

Prometheus metrics

Built-in health endpoint and Prometheus metrics. Works with your existing observability stack.
