OpenViber

You Imagine It. Tasks Build It.

English · 简体中文 · Documentation · Feedback

OpenViber is an open-source platform that turns your machine into a Viber — hosting role-scoped AI workers called tasks that automate real work. Unlike cloud-based agent frameworks, OpenViber runs locally with full privacy, connects outbound to your enterprise channels, and works autonomously while you sleep.

⭐ 100% Open Source · 🥇 Local Deployment · 🏆 MCP Integration

• ✅ Zero Setup — No servers to host, just npx openviber start
• ✅ Task Workforce — Role-scoped tasks working in parallel
• ✅ Human-in-the-Loop — Enterprise messaging channels (DingTalk, WeCom)
• ✅ Privacy First — 100% local execution, data never leaves your machine

🚀 Quick Start

The fastest way to get started is using npx:

# 1. Set your API key (OpenRouter recommended)
export OPENROUTER_API_KEY="your_api_key_here"

# 2. Start OpenViber (Standalone Mode)
npx openviber start

If you prefer to install it globally:

npm install -g openviber
viber start

🛠️ Development Setup

If you want to contribute or run from source:

1. Prerequisites

• Node.js v18+ and pnpm (recommended)
• tmux installed (brew install tmux on macOS)

2. Installation

git clone https://github.com/dustland/openviber.git
cd openviber
pnpm install

# Configure environment
cp .env.example .env
# Add your OPENROUTER_API_KEY to .env

3. Launch full stack

# Starts Gateway + Viber runtime (port 6009) and Web UI (port 6006)
pnpm dev

• Viber Board (Web UI): http://localhost:6006
• Viber Gateway: http://localhost:6009

🧵 Interactive Experience

OpenViber provides multiple ways to interact with your vibers, designed for both developers and teams.

💻 Terminal Chat (tmux-friendly)

Use OpenViber from any terminal. It integrates deeply with tmux for streaming output and managing long-running tasks.

# Start an interactive chat
viber chat

🌐 Viber Board (Web UI)

A modern, visual interface to manage your tasks, monitor jobs, and chat in real-time. Accessible at http://localhost:6006 when running pnpm dev.

🏢 Enterprise Channels

Deploy your tasks to where your team works. Support for DingTalk and WeCom is built-in.

# Start the enterprise channel server
# Note: Defaults to port 6009. If running alongside 'viber start' (which also uses 6009), use a different port:
viber channels --port 6010

🧠 Personalization (The Three-File Pattern)

OpenViber follows a standardized configuration pattern for AI personality. Three markdown files define your task's complete behavior:

| File | Scope | Purpose | Update Frequency | |------|-------|---------|------------------| | user.md | Shared | Who you are, current projects, priorities | Daily/Weekly | | soul.md | Per-task | Communication style, boundaries, rules | Monthly | | memory.md | Per-task | Decisions, learned patterns, corrections | Grows organically |

Location: ~/.openviber/vibers/default/

✨ Key Features

🤖 Task Workforce (Jobs)

Deploy autonomous workers via simple YAML cron jobs.

# examples/jobs/morning-standup.yaml
name: morning-standup
schedule: "0 9 * * 1-5" # Every weekday at 9 AM
prompt: "Check GitHub notifications, summarize what needs my attention."

🔧 Zero Configuration Skills

Capabilities are defined in SKILL.md files. No complex code required to extend your tasks.

---
name: git-commit
description: Stage and commit changes
---
git add . && git commit -m "$message"

🌐 Model Context Protocol (MCP)

Seamlessly connect to any MCP server to give your tasks access to external tools like Google Maps, Slack, or custom internal APIs.

👤 Human-in-the-Loop

Maintain control with approval gates. Tasks can be configured to pause and ask for permission before executing sensitive actions (e.g., deleting files, making payments).
