Plasma has launched Fractal, an open-source tool designed to enhance coding agents’ capabilities by enabling hierarchical agent loops that facilitate large-scale autonomous work. Released under the Apache 2.0 license, Fractal addresses the challenges faced by coding agents during complex tasks like migrations or audits, which often disrupt single-threaded workflows. With this new architecture, each node in the system can maintain its own worktree, memory, and lifecycle, allowing for independent execution cycles that can efficiently handle multiple tasks. Users can easily install Fractal using pip and access it on GitHub.

Plasma: Plasma is an AI organization focused on developing tools for autonomous coding agents and complex software workflows. They built and released Fractal to solve persistent challenges in scaling single-agent systems for large projects. The project emphasizes open-source contributions under Apache 2.0 for hierarchical agent architectures.
Fractal: Fractal is an open-source tool designed for building hierarchical agent loops in AI coding environments. It equips each node with independent worktrees, memory, lifecycles, and reviewable Git history to support repeated Prepare-Plan-Execute-Review-Commit cycles. The system enables child nodes to branch off and operate autonomously when tasks split, integrating with tools like Claude Code and Codex.

Agent Architecture: The framework supports splitting work across nodes that maintain persistent ownership and independent execution loops for complex tasks like migrations or audits.
Open Source Availability: Fractal is released under the Apache 2.0 license with straightforward pip installation and public GitHub access.
