Installation

Quick Install

Termly CLI includes prebuilt binaries for all platforms - no compilation required!

All Platforms:

npm install -g @termly-dev/cli

After installation, the termly command is available globally.

That's it! Works out-of-the-box on:

• ✅ macOS (Intel & Apple Silicon)
• ✅ Linux (x64 & ARM64)
• ✅ Windows 10+ (x64 & ARM64)

Development (Beta Testing)

For beta testers and development:

npm install -g @termly-dev/cli-dev

This installs the termly-dev command which connects to the development environment.

System Requirements

Node.js 18+ - That's all you need!

Termly CLI uses @lydell/node-pty with prebuilt binaries for all platforms:

• No Visual Studio required on Windows
• No Xcode CLI tools required on macOS
• No build-essential required on Linux
• Fast installation (no compilation)

Installation typically completes in 10-30 seconds.

Environments

Termly CLI supports three environments:

Note: Server URLs are hardcoded per environment and cannot be changed by users.

Quick Start

Production

cd /path/to/your/project
termly start

Development

cd /path/to/your/project
termly-dev start

Local Development

# Clone the repo
git clone https://github.com/termly-dev/termly-cli
cd termly-cli
npm install

# Run with local environment
TERMLY_ENV=local node bin/cli.js start

Multiple Sessions

Run multiple sessions simultaneously:

# Terminal 1
cd ~/frontend
termly start

# Terminal 2 (new window)
cd ~/backend
termly start

Each session:

• Independent AI tool instance
• Own WebSocket connection
• Can connect one mobile device

Manage sessions:

termly status        # Show all sessions
termly stop abc-123  # Stop specific session
termly list          # Quick list

Commands

All commands work the same way in both termly (production) and termly-dev (development).

Setup

termly setup

Interactive configuration setup (optional - sets default AI tool preference).

Start

termly start [directory] [options]

Start a new session with AI tool.

Options:

• --ai <tool> - Specify AI tool to use
• --ai-args <args> - Additional arguments for AI tool
• --no-auto-detect - Disable auto-detection
• --debug - Enable debug logging

Examples:

# Auto-detect and start
termly start

# Use Aider explicitly
termly start --ai aider

# Use Claude Code with custom directory
termly start /path/to/project --ai "claude code"

# Pass arguments to AI tool
termly start --ai aider --ai-args "--model gpt-4"

# Continue previous Claude Code session (restore context after restart)
termly start --ai claude-code --ai-args "--continue"

Status

termly status [--all]

Show all active sessions with detailed information.

Stop

termly stop [session-id] [--all]

Stop one or all sessions.

List

termly list

Quick list of active sessions with encryption fingerprints for verification.

Tools

termly tools list           # List available AI tools
termly tools detect         # Detect installed tools
termly tools info <tool>    # Show tool information

Config

termly config               # Show current configuration
termly config get <key>     # Get config value
termly config set <key> <value>  # Set config value

Examples:

termly config set defaultAI aider
termly config get defaultAI

Note: Server URL is determined by environment and cannot be changed via config.

Cleanup

termly cleanup

Remove stale sessions (processes that are no longer running).

Requirements

• Node.js 18+
• At least one AI coding assistant installed (see Supported AI Tools section)
• Mobile app (iOS/Android) - coming soon

Troubleshooting

Installation Issues

Installation usually works flawlessly thanks to prebuilt binaries.

If you encounter issues:

"Cannot find module 'node-pty'"

Reinstall the package:

npm uninstall -g @termly-dev/cli
npm cache clean --force
npm install -g @termly-dev/cli

Permission errors on macOS/Linux

Use sudo or fix npm permissions:

# Option 1: Use sudo
sudo npm install -g @termly-dev/cli

# Option 2: Fix npm permissions (recommended)
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc
source ~/.bashrc
npm install -g @termly-dev/cli

Windows: "EPERM: operation not permitted"

This is usually a warning, not a fatal error. Check if installation succeeded:

termly --version

If the command works, installation was successful.

Usage Issues

No AI tools detected?

termly tools list  # Check what's installed

Install an AI tool:

• Claude Code: https://docs.claude.com
• Aider: pip install aider-chat
• GitHub Copilot: gh extension install github/gh-copilot

Session already running?

termly status       # Find session ID
termly stop abc-123 # Stop it

Check your environment:

termly config  # Shows current environment and server URL

Logs: ~/.termly/logs/cli.log

Security

• End-to-end encryption (AES-256-GCM)
• Diffie-Hellman key exchange (2048-bit)
• Fingerprint verification - Compare encryption keys between CLI and mobile app
• Zero-knowledge server - Server cannot decrypt your data
• One mobile device per session
• Environment isolation - Production and development separated
• Version enforcement - Automatic check for minimum supported version
• Open source - Audit the code yourself

Architecture

Termly CLI uses a PTY (pseudo-terminal) to spawn AI tools locally and streams I/O through WebSocket with end-to-end encryption.

Mobile App <--[encrypted]--> WebSocket Server <--[encrypted]--> CLI <--[local]--> PTY <--> AI Tool

Key features:

• Circular buffer - Stores last 100KB for session resume
• Platform-specific optimizations - Windows output deduplication and escape sequence normalization
• Batch catchup - Sends missed messages in 100-message batches with 10ms delay

For detailed architecture diagrams and data flow, see docs/ARCHITECTURE.md.
