Plasma opens Fractal, a local agent-tree CLI for complex coding work
rohanpaul_ai · x · 2026-07-22
Plasma open-sourced Fractal, a command-line tool that turns a single Claude Code or Codex session into a persistent tree of agents.
Why it matters
Large coding tasks often do not fit cleanly inside one agent's context window or one shared workspace. Fractal splits the job into nodes that each own their own git worktree and memory, so different parts of the problem can progress in parallel.
How it works
- Each child node gets its own context, budget, and memory.
- Parents can steer or stop any node while it runs.
- Every run, cost, and signal is written to a local SQLite database.
- Every iteration ends in a git commit, making the whole run readable as normal git history.
Deployment
- Apache 2.0, free for commercial use.
- Runs fully on your machine.
- No hosted server required.
- Works with Claude Code, Codex, Grok Build, OpenCode, and Oh My Pi.
