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:

• Developer tools: pw_ide Bazel code intelligence and VS Code UI overhaul - pw_ide overhauled Bazel code intelligence for VS Code, shifting to preconfigured compile commands aspects and simplifying the UI for a zero-setup developer experience.

• Kernel: Userspace process control - Processes can now completely monitor and control each other.

• Developer tools: pw_presubmit v2 - Introduced a new v2 presubmit system supporting automatic fixes and commit-by-commit execution.

• Async and concurrency: Void future support in pw::async2::Select - The Select combinator now supports mixtures of value-returning and void-returning futures.

And more! See What’s new in Pigweed: April 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!
