# Fractals

> Recursive task orchestrator running agent swarms in isolated git worktrees.

Fractals is an open-source task orchestrator developed by TinyAGI that breaks complex software tasks into hierarchical, self-similar subtask trees. Each leaf task executes independently using AI coding agents (like Claude CLI or Codex) inside isolated git worktrees. It provides a Next.js web interface and an API server to inspect plans, manage workspaces, and track batch execution.

## What it is for

- Break down large software features into isolated subtasks for parallel AI coding
- Run multiple agentic coding tasks concurrently in separate git worktrees
- Review and approve AI-generated project plans before committing to execution
- Orchestrate batch execution of coding subtasks across repository branches

## Features

- Recursive task decomposition using structured LLM outputs down to atomic units
- Isolated execution where each leaf subtask runs in its own git worktree and branch
- Support for CLI-based agent executors like Claude and Codex
- Depth-first batch execution strategy to manage API rate limits
- Next.js web UI for task submission, tree visualization, and status polling
- Hono-based API server running on port 1618 with CLI entry points
- Automated git workspace initialization and tracking
