## What it is
uFBT is a compact, cross-platform Python CLI tool for building and debugging applications for the Flipper Zero device. It downloads a prebuilt SDK and toolchain so developers can compile, flash, and debug Flipper apps without building the full firmware.

## Use cases
- build a Flipper Zero app from its application.fam manifest
- compile a .fap without building the whole firmware
- flash firmware to Flipper Zero over USB or SWD
- debug Flipper applications from VSCode
- scaffold a new Flipper app template
- automate FAP builds in GitHub Actions CI

## When to choose
- you are developing a standalone application (.fap) for Flipper Zero
- you want a lightweight alternative to the full FBT firmware build
- you need cross-platform builds on Linux, macOS, or Windows
- you want CI automation for Flipper app builds

## When to avoid
- you need to modify or build the Flipper Zero firmware itself
- you target other embedded platforms
- you need a GUI-based development environment
