Session Relay

Pick up where your teammate left off. Share coding-agent sessions across Claude Code, Codex, OpenCode, Gemini CLI, Copilot CLI, Cursor and ZCode. Your teammate continues in whichever tool they use, with the goal, decisions, next steps and recent conversation.

You (Claude Code):      /share
Teammate (OpenCode):    /pickup your webhook retry work

Why

Handing off agent work means copy-pasting chat logs, or the next person starting from zero. With Session Relay:

• /share: the agent writes a handoff (goal, decisions, done, next steps, open questions) and shares it with the recent conversation and the files touched.
• /pickup: the next person's agent finds it, reads it, checks the code and continues, in any of the supported agents.
• Handoff chains: work picked up and shared again is linked, so every session shows who started it and who continued it.
• Work live together (/live): when two people work at the same time, see who's on what and which files they touch, and send messages that reach each other's agent between steps. Agents show messages to you first, unless you let them act on their own.
• Handoffs for someone: share "for Akshat" and it's first in their /pickup. Edit a share any time (next steps, title, who it's for).
• Auto-share drafts (opt-in): every Claude Code, Gemini CLI and Copilot CLI session is saved as a private draft when it ends; publish it when it's ready.
• Share without your prompts: /share without my prompts or relay config prompts hide keeps what you typed on your laptop; teammates still get the agent's work and the summary.
• Diff snapshots: attach your uncommitted changes to a share; the next person git applys them.
• Handoff templates: admins decide what a handoff must include per repo ("Tests run", "Migration notes") in a guided editor with ready-made sections and a preview; /share follows it.
• Comments: teammates leave notes on a session; the agent that picks it up reads them.
• Linked to PRs and files: shares carry the branch's pull request; find every session that touched a file with file:src/billing.ts.
• Web app: browse, search and read everything your team has shared (All, For me, Shared by me, My drafts), plus an Activity digest, team Stats and Settings in simple tabs. Light and dark, works on phones.
• Export and audit: download any session as Markdown or JSON; admins see an audit log of everything.
• Easy onboarding: invite links, and relay login signs in through the browser.
• Search everything: titles, summaries and full transcripts; filter by file, branch, agent, person.
• Private by default: nothing is uploaded unless you share it, secrets are removed on your laptop first (test your own patterns in Settings → Privacy), and shares can be limited to specific people.

All of it: Features.

Hosting

The CLI is on npm: session-relay.

Quick start

Run the server (once per team):

git clone https://github.com/Ryrahul/session-relay.git && cd session-relay
cp deploy/.env.example deploy/.env          # set POSTGRES_PASSWORD, PUBLIC_URL, DOMAIN
docker compose -f deploy/docker-compose.yml --env-file deploy/.env up -d --build
docker compose -f deploy/docker-compose.yml --env-file deploy/.env logs server | grep -A2 "setup code"

Open your server's URL, enter the setup code, and create your organization. You're the owner.

Connect each laptop:

npm install -g session-relay
relay login --server https://relay.your-team.com    # approve in the browser
relay setup        # adds /share, /pickup and /live to every agent you have installed
