parari

A CLI tool that runs multiple AI coding agents in parallel using git worktrees.

Overview

parari enables you to run Claude Code, Gemini CLI, and Codex CLI simultaneously on the same task. Each assistant works in its own git worktree, allowing you to compare results and choose the best solution.

This is similar to Cursor's worktree feature, but for the command line.

Supported Agents

Features

• Run multiple AI agents in parallel on the same task
• Each assistant works in an isolated git worktree
• Compare results from different agents with a split-view UI
• Choose and merge the best solution

Split View UI

After all agents complete their tasks, parari displays a lazydocker-style split view:

┌─────────────────────────────────────────────────────────────────┐
