Persistent messaging for AI agents.

License Go Report Card CI Release Go Version

Thrum gives AI agents a way to message each other across sessions, worktrees, and machines. You direct the work. The agents coordinate through Thrum. Messages persist through context compaction, session restarts, and machine changes — nothing gets lost.

Quick Start

# Install
curl -fsSL https://raw.githubusercontent.com/leonletto/thrum/main/scripts/install.sh | sh

# Initialize. On a TTY this launches an opinionated wizard that walks you
# through identity, worktrees root, role templates, and starts the daemon.
cd your-project
thrum init

# Send your first message (the wizard already registered your agent)
thrum send "Starting work on auth module" --to @implementer
thrum inbox

Need a non-interactive flow for CI? Pass --non-interactive for the legacy silent init, or pre-fill every wizard prompt:

thrum init --name myagent --role planner --module auth \
           --worktrees-root ~/.thrum/worktrees/myproj \
           --roles=enhanced --no-daemon

How It Works

Thrum is a single binary: CLI, daemon, web UI, and optional MCP server.

Thrum architecture

  • CLI-first. Every agent that can run shell commands can use Thrum. No SDK, no framework, no protocol to implement.
  • Offline-first. Everything works locally. Git push/pull syncs when ready.
  • Zero-conflict. Messages live on a dedicated orphan branch — no merge conflicts with your code.
  • Inspectable. Messages are JSONL files. State is a SQLite database. Sync is plain Git. If something goes wrong, you look at files.

What You Can Do

  • Send and receive messages — thrum send, thrum inbox, thrum reply
  • See what everyone is working on — thrum team, thrum who-has
  • Coordinate agents across worktrees — each worktree gets its own identity
  • Broadcast critical alerts — escalations reach every active agent
  • Monitor in real time — embedded web UI with live feed, threaded inbox, agent list
  • Get messages on your phone — Telegram bridge with bidirectional threading
  • Sync across machines — automatic Git sync, or Tailscale for real-time peer-to-peer

Installation

Every release soaks for 48h+ as -rc.N before going stable. To help test releases before they're promoted, see Beta channel.

Daily Commands

You only need about 8 commands for daily use:

Command What it does
thrum quickstart --name NAME --role ROLE Register agent and start session
thrum send "message" --to @name Send a message
thrum inbox Check your messages
thrum reply MSG_ID "response" Reply to a message
thrum team See what everyone is working on
thrum who-has FILE Check who's editing a file
thrum overview Status, team, inbox in one view
thrum status Your current state

Everything else — agent lifecycle, sessions, context management — is infrastructure that agents use programmatically. See the CLI Reference for the full list.

Agent Setup

Install the Thrum Skill (All Agents)

Auto-detects your agent (Claude Code, Cursor, Codex, Gemini, Augment, Amp) and installs the thrum skill to the right location. If multiple agents are detected, you'll be prompted to choose. Works with any agent that supports the SKILL.md format.

Claude Code Plugin (Full Integration)

For Claude Code users who want the complete experience — slash commands, automatic context injection, hooks, and startup scripts:

claude plugin marketplace add https://github.com/leonletto/thrum
claude plugin install thrum

See Claude Code Plugin. If the plugin is already installed, thrum init --skills will detect it and skip the install.

Any Agent via CLI

Any agent that can run shell commands works with Thrum. No plugin or skill required — just call thrum from the command line.
