Handing Off Claude Code / Codex Sessions Between Two Macs: Syncthing + session-index-viewer

2026-06-19T10:00:00+09:00

Background

The pain point is straightforward: I have two MacBooks (A and B), and I heavily use both Claude Code and Codex for work and side projects on both machines. I wanted to switch seamlessly between them and resume previous sessions at any time.

Since their actual session data is stored locally as indexable session files (while state is also tracked upstream), as long as the session files on both sides are synchronized, I can resume right where I left off from either computer. Solving the synchronization problem was the first step.

Ditching Portainer for Dockge: What the Abstraction Hides Is the Most Expensive Part

Portainer Really Is Showing Its Age

I love tinkering with Raspberry Pis. I had a Pi 4B that I hacked on for years.

Before GPU prices went through the roof last year, I bought a Pi 5 online and had a blast with it. For the container layer, I used Portainer just like I did on the 4B.

Portainer is great when you’re starting out: it has a UI, clickable buttons, one-click stack deployment, and you don’t need to memorize docker compose commands just to change an environment variable. But the longer you use it, the more small annoyances keep recurring.
