Tomorrow.io plans
| Plan | Price | What it covers |
|---|---|---|
| Free API Plan | $0 | 500 API calls/day, 3 req/s, up to 5-day forecast, 1 weather alert, 1 monitored location; core parameters (temp, wind, precip, humidity). |
| API Plan (paid) | Usage-based / contact sales | Priced on API call volume with tiers for higher demand; unlocks premium layers (pollen, lightning, air quality) and longer forecasts. No public per-call price. |
| Platform Plan | Contact sales | Cost depends on team size, number of monitored locations, and feature usage; for the Weather Intelligence Platform UI rather than raw API. |
- Premium parameters and any real scale are gated behind 'contact sales' with no published paid per-call pricing
- Free tier is restrictive (3 req/s, 5-day forecast, 1 alert, 1 location), limited for anything beyond prototyping
