Weather APIs pricing
Weather APIs span legacy meteorological brands, developer-first freemium services, and a new wave of high-resolution forecast platforms. The category splits cleanly on three axes: docs/DX quality, proven reliability at scale (published SLAs + status history), and how frictionless it is to get a working key. Incumbents like AccuWeather carry brand and data depth but gate access behind trials and tiers; challengers like Open-Meteo and WeatherAPI.com win on instant self-serve access and generous free tiers; Tomorrow.io leads on modern docs and proprietary high-res data. Compare on free-tier generosity, signup friction, SDK breadth, and whether a documented 99.9%+ SLA backs production use.
