Claude Session Relay

Resume Claude Code sessions seamlessly across multiple Macs and your iPhone

Problem

Developers juggle several Macs and a phone, yet Claude sessions are tied to a local machine, so moving work between devices means manually shuttling project folders through cloud drives. Multiple accounts and instances make it worse, and one developer even weekend-built a TUI just to dig through thousands of sessions and forks.

Solution

A lightweight desktop sync daemon that packages session directories, project context, and account profiles into portable workspaces synced through the user's own cloud drive or a peer-to-peer channel. It offers a browser for sessions and forks, letting you pick which session to resume when you switch devices.

Users

Heavy Claude Code users, freelancers, and developers who switch between laptop and desktop

MVP

Scan local session directories and list sessions and forks; one-click package of the current workspace into a user-chosen sync folder; restore on a new device and list resumable sessions; switch between multiple account profiles; no data sent to third-party servers

Revenue

Free tier for one sync target; Pro subscription ($5–8/month) for multi-device and multi-account; or a one-time license

Why now

Claude Code is now a primary tool for many developers while official multi-device and multi-account support remains rough; the scope is narrow, needs no model capability, and one indie can ship it fast
