Fractal
Fractal is a framework for building recursive agent systems that allow autonomous agents to decompose complex tasks into a hierarchy of sub-agents. Each agent runs in its own git worktree, maintains persistent memory, and operates within a defined budget to handle tasks that exceed individual context windows.
Launched as an open-source project in July 2026, with ongoing refinements to budget monitoring, recursive logic, and the integration of the Plasma Wiki for durable agent memory.
As of
- Hierarchical recursive agent loops
- Git worktree isolation for parallel task execution
- Built-in budget and cost tracking per node
- Interactive terminal UI for monitoring agent trees
- Support for multiple backends including Claude Code, Codex, and Grok
Long-running, complex engineering tasks like large-scale refactors, migrations, and deep research that require persistent coordination and branching sub-tasks.
Simple, short-lived tasks that can be completed within a single prompt, or environments where you cannot provide a sandboxed or disposable host for agent execution.
Fractal is released under the Apache 2.0 license and is currently free to use, though cloud-based features with cost tracking are in development.
Fractal is a powerful, highly specialized tool for complex multi-agent orchestration that excels at breaking down massive, long-horizon coding projects into manageable, verifiable recursive loops.
Is Fractal free?
Yes - Fractal is Open Source. Fractal is released under the Apache 2.0 license and is currently free to use, though cloud-based features with cost tracking are in development.
