Overview
Some CloudLinux/cPanel servers support application managers for Node.js, Python, or Ruby. Availability depends on the hosting plan and server configuration.
Common requirements
- Correct runtime version.
- Application startup file.
- Passenger or application manager configuration.
- Environment variables.
- Dependencies installed inside the account.
- Proper document root or reverse proxy mapping.
Support note
Shared hosting is not always the right environment for long-running custom apps. VPS hosting may be better for applications needing custom services, daemons, sockets, or background workers.
Shared hosting impact
CloudLinux and CageFS protect the whole server by isolating users and limiting runaway accounts. When a site hits limits, the fix may be optimization, malware cleanup, bot blocking, plan upgrade, or moving to VPS/dedicated hosting.
