Session Relay
Overview
The problem
Claude Code keeps every conversation on the machine where it happened. Start a task on the desktop, continue on the laptop, and the session, its subagent logs and the project memory aren't there. Checkouts also live at different paths on each machine, so even copied sessions point at folders that don't exist.
The solution
Session Relay groups sessions by GitHub project instead of folder path, packs them into encrypted snapshots and keeps them in a private repository you own. Each project shows one button for what it needs, paths are rewritten on the way in, and auto-save pushes after every Claude reply.
Features
What it does
Grouped by GitHub project
Sessions line up by remote and folder, so a project matches on every machine even when it's checked out somewhere else.
One button per project
Save, Restore or Sync: every status maps to a single, clear action.
Auto-save after each reply
Claude Code hooks mark the project and a background worker pushes it minutes later. Push-only, it never overwrites.
Built-in session viewer
Read any session from disk or straight from the cloud: replies, tool calls, file diffs and subagents.
New machine in minutes
Finds existing checkouts in your workspace folders or clones the repository, then restores its sessions.
Per-file conflict resolution
When both machines changed the same session, pick a side per file and compare both copies.
How it works
From one machine to the next
- 01
Collect
Reads each project's sessions, subagent logs, tool results and memory.
- 02
Encrypt
Chunks transcripts, compresses them with zstd and encrypts them with age. Names become keyed hashes.
- 03
Push
Commits one snapshot to your private GitHub repository through your own GitHub App.
- 04
Restore
Another machine pulls, decrypts and rewrites paths to its own checkout, then Claude resumes.
Highlights
Security by design
Encrypted before it leaves
zstd + age (x25519) on this machine; the repository only ever sees sizes and timing.
Passphrase-wrapped key
The age identity is wrapped with your passphrase (scrypt). Nobody else can recover the data.
Short-lived tokens
GitHub App device-flow sign-in, scoped to the storage repository, expiring after 8 hours.
Refuses public repositories
The storage repository is re-checked daily; if it ever turns public, syncing stops.
