Skip to content# session-porter > Move AI coding sessions between Claude Code and Codex CLI without losing context. **Status:** Released | **Language:** TypeScript | **License:** MIT **Repo:** https://github.com/liwala/session-porter ## The Problem Claude Code and Codex CLI both store sessions as JSONL on disk — but in incompatible shapes. Switching tools mid-task means losing the entire conversation, or pasting summaries back and forth by hand. ## What It Does - List, summarize, and show sessions from any installed agent - Transfer sessions between Claude Code and Codex CLI (and back) - Four transfer modes: raw, full, compact, resume-only - Fork part of a session (last-N turns, from-turn N) - Export to JSON, Markdown, or each agent's native JSONL - Generate compressed handoff briefs you can paste into any agent - Registers Codex sessions in the SQLite database for codex resume - Local-only, zero network, zero API keys ## Quick Start ```bash npm install -g @liwala/session-porter session-porter list --claude -n 10 session-porter summary <session-id> session-porter transfer <session-id> --to codex --mode compact codex resume <session-id> ```
