Verdict
OpenWeather and Visual Crossing are the two go-to answers when a developer wants a weather API without an enterprise sales call, and both back that up with a genuinely usable free tier rather than a locked demo. The difference is what they are optimized for: OpenWeather is built around a broad set of current-conditions, forecast and specialty (air pollution, map tile) endpoints for embedding live weather into an app, while Visual Crossing is built around more than 50 years of historical records and a bulk-download, query-builder workflow aimed at analysts doing research rather than developers shipping a widget.
Choose OpenWeather if
- You are embedding current conditions, a short-term forecast, or map tile layers into an app or IoT product.
- You want the widest range of live endpoints — pollution, UV index, severe alerts — in one API.
- Your usage is light enough that the permanent free tier (1,000 calls/day) covers it, or you are comfortable scaling through published Startup/Developer/Professional/Expert tiers.
Choose Visual Crossing if
- Your core need is historical weather data — backtesting a model, researching a claim, building a long time series — not a live feed.
- You want a self-serve cost calculator and bulk CSV/Excel export rather than writing API integration code for every pull.
- You need higher-tier parameters like solar, wind and soil data alongside the historical record.
The honest caveat
Neither publishes full per-tier dollar pricing beyond the free plan on the pages checked for this guide, so budget a trial against your real usage before committing to a paid tier. Both are consumer-grade APIs built on public model data rather than a proprietary observation network — if your use case needs the higher resolution or domain-specific parameters that come from a provider running its own forecasting infrastructure, see choosing a weather data API for where Meteomatics and Tomorrow.io fit instead. See also API integration for what to check before you build against either one.
