AgentTrace Relay

End-to-end encrypted session handoff for coding agents across devices

Problem

Developers start an agent session on a laptop but want to continue it on a server or hand it to a colleague. Hosted options upload a cloud copy of the repo, so local hooks and config don't come along, and many won't trust a third party with traces worth $50-100 each on the market. Others have ideas on their phone while the session only lives on their desktop.

Solution

A local-first CLI plus PWA: one command discovers and packages the current agent session including local config and hooks, encrypts it client-side, syncs through a self-hosted relay or the user's own object storage, and restores it on another device. One-time share links let colleagues pick up the session without the server ever seeing plaintext.

Users

Indie developers and small teams who live in Claude Code, Codex, or Cursor

MVP

One CLI command to detect and export the current session; client-side encryption and upload to user's S3/WebDAV or built-in relay; restore via PWA or second command; one-time share links with expiry; migrate local config and hooks alongside

Revenue

Open-source CLI free; subscription of $5-10/month or usage-based billing for the encrypted relay; team tier adds share permission management

Why now

Coding agent usage is exploding while sessions remain stuck on one machine, and trust in hosted trace services is openly debated; an E2E relay is a weekend-to-two-week backend project
