Both are open source harness options with comparable terms, so the choice comes down to which model of the problem you prefer — compare the descriptions below rather than the licence.
Open-source meta-harness that orchestrates Claude Code, Codex, Cursor, OpenCode, Hermes and Pi from one session, on any device.
A common orchestration layer over other harnesses rather than a harness of its own — swap Claude Code/Codex/Cursor/etc. in and out, enforce policies, and run sessions in cloud sandboxes (Modal, Daytona, E2B and others).
Prime Intellect's recursive-language-model harness — a persistent IPython kernel is the only tool, sub-agents are function calls.
Drops fixed tool schemas and context compaction: the agent writes programs over its own context, and can CRUD its own prompts, skills and sub-agents mid-run.
