Pigweed

Sustained, robust, and rapid embedded product development for large teams

Get started

Overview

Understand the core components of Pigweed and determine whether Pigweed is a good fit for your project.

Tour of Pigweed

Explore key Pigweed features, such as hermetic building, full C++ code intelligence in VS Code, communicating with devices over RPC, host-side and on-device unit tests, and lots more in a guided walkthrough.

Bazel quickstart

Fork our minimal, Bazel-based starter project to create a new Pigweed project from scratch. The project includes a basic blinky LED program that runs on Raspberry Pi Picos and can be simulated on your development host.

More get started guides

Set up a C++-based Zephyr project, set up GitHub Actions, integrate Pigweed into an existing Bazel project, and more.

What’s new in Pigweed?

Highlights:

• Cryptography and security: ChaCha20 cipher support in pw_crypto - pw_crypto now supports the ChaCha20 stream cipher.

• C++ data structures and utilities: - New pw_enum module pw_enum provides automatic stringification and tokenization of C++ enums.

• Async and concurrency: Notification channels and void coroutines in pw_async2 - Improved support for void channels, which can be used to signal tasks without transmitting data, as well as using co_await for coroutines that return void.

• Developer tools: Log file viewing in pw_console - pw_console now directly supports opening and viewing log files (including zip archives).

And more! See What’s new in Pigweed: May 2026.

What is Pigweed?

Libraries

Over 150 libraries (“modules”) enabling you to use modern C++ and software development best practices without compromising performance, code size, or memory

Automation

Easier automated building, testing, and linting for Bazel, GN, and CMake projects

Environments

Hermetic and reproducible development environments for your entire team - no more struggling with toolchains and the “it worked on my machine” problem

Who’s using Pigweed?

Pigweed has shipped in millions of devices, including Google’s suite of Pixel devices, Nest thermostats, satellites, and autonomous aerial drones.

Showcase: pw_console

pw_console is our multi-purpose, pluggable REPL and log viewer. It’s designed to be a complete development and manufacturing solution for interacting with hardware devices via pw_rpc over a pw_hdlc transport. Gone are the days of hacking together a REPL and log viewer for each new project!
