These apps are not really competing for the same job. Windy reads weather systems, Windguru stacks models, iKitesurf watches live stations, Windfinder covers the world broadly, and WindSensei answers whether your specific spots are worth riding. Here is what each one is genuinely good at.

A dash means the product does not offer that capability, not that it is worse. Windy has no session log because it is a weather map, not a training tool.
Map-first weather visualisation running several global models, used well beyond wind sports.
The long-standing forecast table for windsurfers and kitesurfers, with a large community-built spot database.
A network of real-time observation stations, with forecasts built around live sensor data. Strongest in the United States.
Broad global spot coverage with clean, readable forecasts and reports. Widely used across Europe.
There is no single answer, because they solve different problems. Windy is the best tool for reading a weather system across a region. Windguru is the fastest way to compare several models for one spot if you can read the tables. iKitesurf is strongest where its live station network has coverage. Windfinder is excellent for checking an unfamiliar spot while travelling. WindSensei is built for the narrower question of whether your specific spots are worth riding this week.
Windy itself is free at its core, with a paid premium tier for extra models and higher resolution. WindSensei is free with no paid tier, but it is a different kind of product: spot-specific scored forecasts rather than a general-purpose weather map.
Windguru presents model output as a table and leaves the interpretation to you. WindSensei applies your spot's usable wind directions and your own wind range to every forecast hour, so the output is a rating rather than a grid of numbers. Experienced riders often prefer the raw table; riders who do not want to hold that mapping in their head prefer the scored view.
Not currently. WindSensei runs on the web, iOS and watchOS. The web app works on Android in a browser, but there is no native Android app, and session logging from a watch is Apple Watch only. Windy, Windguru, iKitesurf and Windfinder all have native Android apps.
WindSensei exposes an MCP connector, so you can connect it to Claude, Codex and other MCP clients and ask for good riding windows in plain language, scored with your saved preferences. See the integrations page for setup.
The difference only shows up on spots you actually ride. Add yours, set the directions that work, and see whether a scored forecast beats reading a table. Free, no card.
