Connecting Cursor to Replit via SSH

tip

Connect Cursor to your Replit projects using SSH for a seamless development experience.

Prerequisites​

Before you begin, ensure you have:

  • Cursor installed
  • Replit account
  • SSH client installed
  • Basic understanding of terminal commands

Setting Up SSH Keys​

1. Generate SSH Key​

# Generate SSH key
ssh-keygen -t ed25519 -C "[email protected]"

# Start SSH agent
Start-Service ssh-agent
ssh-add $env:USERPROFILE\.ssh\id_ed25519

2. Add Key to Replit​

  1. Copy your public key:

    # Windows
    type $env:USERPROFILE\.ssh\id_ed25519.pub

    # macOS/Linux
    cat ~/.ssh/id_ed25519.pub

  2. Add to Replit:

    • Go to Replit Settings
    • Navigate to SSH Keys section
    • Paste your public key
    • Save changes

Configuring Cursor​

1. SSH Config Setup​

Create or edit ~/.ssh/config:

~/.ssh/config
Host replit
    HostName ssh.replit.com
    User your-replit-username
    IdentityFile ~/.ssh/id_ed25519
    ForwardAgent yes

2. Test Connection​

# Test SSH connection
ssh replit

Connecting to Replit Projects​

1. Get Project URL​

# Format: ssh.replit.com:your-username/project-name
replit-url="ssh.replit.com:username/project"

2. Clone Project​

# Clone via SSH
git clone ssh://replit-url

Working with Projects​

1. Remote Development​

# Open project in Cursor
cursor .

# Configure remote settings
{
  "remote.SSH.remotePlatform": "linux",
  "remote.SSH.path": "/usr/bin/ssh"
}

2. Synchronization​

# Push changes
git add .
git commit -m "Update from Cursor"
git push origin main

# Pull changes
git pull origin main

Troubleshooting​

Common Issues​

  1. Connection Refused

    # Check SSH agent
    ssh-add -l

    # Restart SSH agent
    eval "$(ssh-agent -s)"
    ssh-add ~/.ssh/id_ed25519

  2. Authentication Failed

    # Verify key permissions
    chmod 600 ~/.ssh/id_ed25519
    chmod 644 ~/.ssh/id_ed25519.pub

  3. Key Not Found

    # Check SSH config
    ssh -vv replit

Advanced Configuration​

1. Multiple Projects​

~/.ssh/config
Host replit-project1
    HostName ssh.replit.com
    User username
    IdentityFile ~/.ssh/id_ed25519
    RemoteCommand cd /home/runner/project1

Host replit-project2
    HostName ssh.replit.com
    User username
    IdentityFile ~/.ssh/id_ed25519
    RemoteCommand cd /home/runner/project2

2. Custom Port Forwarding​

Host replit
    HostName ssh.replit.com
    User username
    LocalForward 3000 localhost:3000
    LocalForward 8080 localhost:8080

3. Performance Optimization​

Host replit
    HostName ssh.replit.com
    User username
    Compression yes
    TCPKeepAlive yes
    ServerAliveInterval 60

Best Practices​

1. Security​

# Use SSH config file permissions
chmod 600 ~/.ssh/config

# Use key passphrase
ssh-keygen -t ed25519 -C "[email protected]" -N "your-passphrase"

2. Organization​

~/.ssh/
├── config
├── id_ed25519
├── id_ed25519.pub
└── known_hosts

3. Backup​

# Backup SSH configuration
cp -r ~/.ssh ~/.ssh-backup

# Export public keys
ssh-keygen -y -f ~/.ssh/id_ed25519 > ~/ssh-keys-backup.pub

Integration with Git​

1. Git Configuration​

# Set up Git config
git config --global user.name "Your Name"
git config --global user.email "[email protected]"

2. Git Ignore​

.gitignore
# SSH related files
.ssh/
*.pem
*.key

3. Git Hooks​

.git/hooks/pre-push
#!/bin/sh
# Verify SSH connection before push
ssh -T replit || exit 1

Tips for Success​

  1. Regular Maintenance

    • Update SSH keys periodically
    • Check connection health
    • Monitor access logs

  2. Security Best Practices

    • Use strong passphrases
    • Rotate keys regularly
    • Monitor authorized keys

  3. Workflow Optimization

    • Use SSH config aliases
    • Set up automatic connection
    • Configure editor integration
tip

Always keep a backup of your SSH keys and configuration files!
