Flet review
An open-source Python framework for Flutter-based apps across web, desktop, and mobile.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Flet brings Python development to Flutter-based interfaces, with a shared codebase for web, desktop, and mobile applications. Its ready-made controls, event handling, routing, hot reload, and command-line packaging workflow make it a fit for Python developers who want to target Windows, macOS, Linux, iOS, Android, and the web. It also supports custom extensions that wrap Flutter packages and platform integrations, plus Python libraries such as NumPy, pandas, Pillow, and cryptography on mobile. Teams looking for a Python-centered alternative to writing separate platform-specific apps may find the approach relevant; it is less suited to projects that require a different primary language or a larger built-in team plan.
The framework is free and open source; paid plans apply to the optional Flet Studio service. Explorer includes 10 public apps, one user, 20 MB of storage, 1,000 AI credits per month, and community support. Creator costs $25 per month or $300 per year and includes unlimited public and private apps, one user, 100 MB of storage, 10,000 AI credits per month, and Flet support. The published plan details make Creator a step up in app limits, storage, credits, and support, but it remains a single-user plan. Buyers should distinguish the free framework from Studio pricing when comparing costs.
Flet covers app packaging and testing as well as interface development: it can build platform-specific bundles, and its pytest-based tools support packaged-app and screenshot testing. Web deployment can run Python in the browser with Pyodide/WebAssembly or through a server-hosted Python process, giving developers two deployment approaches with different execution models. Documentation, community, and email are listed support channels. Choose Flet if Python, cross-platform reach, and Flutter-based controls are central requirements; consider alternatives if your project depends on a different language or needs multi-user collaboration included in the paid Studio plan.
