Plasma open-sources Fractal for hierarchical coding agents with Git-backed worktrees
rohanpaul_ai · x · 2026-07-22
Plasma has open-sourced Fractal, a hierarchical agent-loop framework for large-scale autonomous coding work.
- It targets the main failure mode of single-session coding agents: large migrations and audits that need persistent ownership across branches.
- Each node gets its own worktree, memory, lifecycle, and reviewable Git history.
- Nodes run repeated Prepare → Plan → Execute → Review → Commit cycles.
- When work splits, a node can spawn children that run the same loop independently.
- Fractal is released under Apache 2.0 and can be installed with pip install fractal.
The post frames this as the missing architecture for making Claude Code and Codex handle truly large autonomous work.
