What is OpenACP?
OpenACP is a self-hosted bridge that connects AI coding agents to your messaging platforms. You chat with an AI agent through Telegram, Discord, or Slack — it reads your codebase, writes code, runs commands, and streams results back to you in real time.
Built on the open Agent Client Protocol (ACP). Your machine, your keys, your data.

Why OpenACP?
| Without OpenACP | With OpenACP | |----------------|-------------| | "Its usage is currently focused on its dedicated terminal REPL and specific IDE integrations" | Control from Telegram, Discord, or Slack — any device, anywhere | | "Codex Desktop App only works with local projects. It does not support development on remote hosts" | Full remote development support — run agents on your server, manage from your phone | | "There's no way to trigger Claude Code sessions from external issue trackers" | REST API for CI/CD integration and external triggers | | "Being able to use a proper mobile app UI would be much better than having to access sessions through ssh + tmux" | Native Telegram/Discord UI — no SSH, no terminal on mobile | | "Cline is really burning up OpenRouter tokens and my wallet" | Built-in usage tracking and monthly budget limits per session |
Use Cases
- Remote coding — Tired of being chained to your desk to run Claude Code? Review PRs, fix bugs, and deploy from your phone via Telegram while away from your desk.
- Team visibility — Share a Discord channel where everyone sees what the AI agent is doing in real time — no more black-box coding sessions.
- Multi-agent workflows — Start with Claude Code for planning, switch to Codex for implementation, use Gemini for review — all in one chat thread, no reconfiguration.
- CI/CD integration — Trigger agent sessions from GitHub Actions or any issue tracker via the REST API.
- Self-hosted AI gateway — Keep API keys and code on your own infrastructure. No third-party cloud, no vendor lock-in.
- Local LLM support — Run agents against self-hosted models (Ollama, LM Studio) via ACP-compatible adapters. Your models, your data.
Installation
Requirements: Node.js 20+ (the installer handles this for you)
macOS
curl -fsSL https://raw.githubusercontent.com/Open-ACP/OpenACP/main/scripts/install.sh | bash
Linux
curl -fsSL https://raw.githubusercontent.com/Open-ACP/OpenACP/main/scripts/install.sh | bash
Works on Debian/Ubuntu, Fedora/RHEL, Arch, and other distros. Also supports WSL (Windows Subsystem for Linux).
Windows
Open PowerShell and run:
powershell -c "irm https://raw.githubusercontent.com/Open-ACP/OpenACP/main/scripts/install.ps1 | iex"
Requires PowerShell 5.1+ (built into Windows 10/11).
Manual install via npm
If you do not have Node.js yet, install it first. For example, on macOS or Linux with nvm:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
nvm install --lts
nvm use --lts
Then install OpenACP with npm:
npm install -g @openacp/cli
openacp
# → Interactive setup wizard starts:
# → ? Choose your platform: Telegram / Discord / Slack
# → ? Enter your bot token: ********
# → ? Select workspace directory: ~/projects
# → ? Choose default AI agent: Claude Code
# → ✓ Configuration saved. Starting OpenACP...
# → 🚀 OpenACP is running. Send a message to your bot!
After installation, the interactive setup wizard walks you through everything:
- Choose your platform (Telegram, Discord, Slack, or multiple)
- Connect your bot (token validation + auto-detection)
- Pick a workspace directory
- Select your default AI agent
- Choose run mode (foreground or daemon)
That's it. Send a message to your bot and start coding.
