Overview

Sidecar puts your entire development workflow in one shell: plan tasks with td, chat with AI agents, review diffs, stage commits, review past conversations, and manage workspaces—all without leaving Sidecar.

Quick Install

macOS (recommended)

brew install marcus/tap/sidecar

This builds from source and avoids macOS Gatekeeper warnings.

Linux / Other

curl -fsSL https://raw.githubusercontent.com/marcus/sidecar/main/scripts/setup.sh | bash

More options: Binary downloads · Manual install

Requirements

• macOS, Linux, or WSL
• Go 1.21+ (only if building from source)

Quick Start

After installation, run from any project directory:

sidecar

Suggested Use

Split your terminal horizontally: run your coding agent (Claude Code, Cursor, etc.) on the left and sidecar on the right.
