StormGlass plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.
| Plan | Price | Features listed | Step up from the tier below |
|---|---|---|---|
| Free | Free | 3 | Entry tier |
| Small | €19/month | 3 | +$19/month, 2 more features |
| Medium | €49/month | 3 | +$30/month, 2 more features |
| Large | €129/month | 3 | +$80/month, 1 more feature |
What each tier adds
The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

What the product covers
The full StormGlass feature record, grouped as the catalogue groups it. This is the product as a whole; the record does not map every feature onto a specific tier.
Other

- Wave forecasts
- Tide data
- Historical weather
Integrations
- REST API
- Webhooks
- SDKs
Platform
- Api support
People bring StormGlass in for pulling marine weather and sea state forecasts into a vessel routing or planning tool, adding tide, wave and wind data to a maritime or coastal application. If that is not the job you are buying for, the alternatives to StormGlass are worth a look before you commit to a tier.
How that compares in Maritime
Too few maritime tools in this directory publish a starting price to quote a meaningful median, so the table below is a like-for-like list rather than a ranking.

Ratings are aggregated from third-party sources and imported with each catalogue entry, they are not reviews hosted on Softwr. How each figure is used is set out on the StormGlass badges page.
Before you pay for StormGlass
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: 4 tiers between Free and €129/month, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
StormGlass runs on api, and is published by StormGlass of Stockholm, Sweden. The full record is on the StormGlass review, and the rest of the category is under best maritime tools.
