Session Migrate

Migrate your sessions to any harness.

  Move coding agent sessions among Claude Code,
  Codex, Pi, Oh My Pi,
  OpenCode,
  GitHub Copilot CLI, Antigravity CLI,
  Cursor Agent, Mistral Vibe,
  Muse Code, Qwen Code, and
  Kimi Code, Grok,
  Kilo Code, OpenHands,
  Hermes Agent, MastraCode, and
  Devin.

Install

Or install with uv:

pipx install session-migrate works too. Python 3.11+ and Linux are currently
supported. The full command is session-migrate; smigrate is the shorthand.
Already installed? Run uv tool upgrade session-migrate.

Quick start

Inspect any native transcript without printing its conversation:

Move a Claude session into Codex and resume it from the same project directory:

Or find an older session by its native title/name first:

Search is case-insensitive and every word must match, in any order. It searches
native titles, names, and IDs—not conversation bodies. A few useful patterns:

catalog refresh is exhaustive inside the default, environment-selected,
registered, and explicitly discovered roots. It does not crawl your whole disk.

Give it to your coding agent

Choose the route on the project website,
or replace the three bracketed values yourself:
Follow https://session-migrate.github.io/llms.txt to migrate a session from
[SOURCE] to [TARGET]. Session: [UUID OR TITLE]

The linked procedure is sandbox-tested with both Claude Code and Codex. See the
agent workflow and verification.
