### TL;DR

Fractal is an open-source framework for building hierarchical, recursive agent loops that manage large-scale, multi-step autonomous work. By organizing agents into a tree of isolated git worktrees, each with its own budget, lifecycle, and memory, Fractal enables complex tasks like large-scale refactors or research campaigns to proceed reliably and independently.
