Fractal Fractal
Fractal is a system for orchestrating hierarchical, recursive agent loops where nodes operate in isolated git worktrees. It enables long-running tasks that exceed single context windows by branching into independently parallelizable sub-tasks with their own budgets and lifecycles.
Open-sourced in July 2026, featuring recursive self-validation capabilities where the system was used to identify and fix bugs within its own codebase.
As of
- Hierarchical recursive agent tree architecture
- Isolated execution environments via git worktrees
- Granular budget controls with cost and time caps
- Terminal-based UI for monitoring and steering
- Adversarial validation and self-improving loops
Large-scale engineering tasks like complex refactors, multi-service features, and research campaigns that benefit from recursive decomposition.
Simple tasks requiring quick, single-step interaction or high-stakes environments where direct, unmonitored agent file system access is restricted.
