Security Best Practices

Securing your OpenCodeHub instance is critical, especially when exposing it to the internet.

1. HTTPS is Mandatory

In production, never run OpenCodeHub over HTTP. Git operations and login credentials must be encrypted.

• Use a reverse proxy (Nginx, Caddy, Traefik) to handle SSL/TLS.
• See the Deployment Guide for Nginx configuration.

2. Generate Strong Secrets

Do not use the default secrets from .env.example.

Generate new 64-character hex secrets for:

• JWT_SECRET
• SESSION_SECRET
• INTERNAL_HOOK_SECRET

openssl rand -hex 32

3. Database Security

• Do not expose your database port (5432/3306) to the public internet.
• Ensure the database user has limited privileges if possible (though migrations require DDL permissions).
• Enable SSL connections to the database by appending ?sslmode=require to your DATABASE_URL.

4. Rate Limiting

OpenCodeHub includes built-in rate limiting.

• Auth: 5 attempts / 15 min
• API: 100 requests / min
• Git: 200 operations / min

You can adjust these in .env if you have a large team behind a NAT, but be careful.

5. Branch Protection

Enable Branch Protection on main for all repositories to prevent:

• Force pushes.
• Deleting the branch.
• Merging without review.

6. Private Mode

If your instance is private:

1. Disable public registration by setting ENABLE_REGISTRATION=false (Future feature, currently needs manual code edit or Invite Only mode).
2. Set default repository visibility to private.
