I've been working on Contextify: https://contextify.sh

Makes it easy to use Claude Code or Codex interchangeably across multiple computers. Personal editions are free, I have a hosted commercial cloud (workgroups share AI history) and commercial self-hosted option available.

It has macOS and Linux clients and I released a guide for setting up the source-available, self-hosted cloud option this week: https://contextify.sh/docs/self-hosted/

I am thinking about the other AI cli environments and providing support for those as well.
