## What it is
PebbleOS is the open-source operating system firmware for Pebble smartwatches, maintained by Core Devices in C. It provides the watch platform, SDK foundations, and tooling for building and flashing Pebble-compatible wearable firmware.

## Use cases
- build custom firmware for a Pebble smartwatch
- contribute to open-source smartwatch OS development
- develop and test apps for Pebble watches
- flash community-maintained Pebble firmware onto hardware
- study an embedded wearable operating system codebase

## When to choose
- you own a Pebble or Core Devices watch and want up-to-date open firmware
- you want to develop or debug Pebble watchapps against the OS source
- you're researching embedded wearable OS design in C

## When to avoid
- you need a general-purpose RTOS for arbitrary microcontrollers
- you want a smartwatch platform with app-store-style managed distribution only
- you need firmware for non-Pebble wearable hardware

## Facets
- artifact type: application
- maturity: active
- function: embedded
- domain: embedded-systems, hardware, cross-platform
- platform: embedded, c, windows
- tags: smartwatch, firmware, pebble, wearables, open-source-hardware, operating-system, linux, macos
