How to Systemd Unit Generator Online
Specify your service name, process description, and absolute ExecStart command (e.g., /usr/bin/node /var/www/app/server.js).
Set execution parameters including WorkingDirectory, non-root User, Group, and Auto-Restart policy (always, on-failure).
Add production environment variables (e.g. PORT=3000, NODE_ENV=production) or reference an EnvironmentFile.
Keep Linux Sandbox & Hardening enabled to generate NoNewPrivileges, ProtectSystem=strict, and PrivateTmp directives.
Copy the generated .service unit file to /etc/systemd/system/<service-name>.service and execute the generated systemctl commands.
Systemd Unit Generator Features
Production Unit File Generation: Scaffolds standard Linux systemd service configurations with full [Unit], [Service], and [Install] blocks.
Linux Sandbox Hardening: Integrates systemd security directives like NoNewPrivileges, ProtectSystem, ProtectHome, PrivateTmp, and MemoryDenyWriteExecute.
Copy-Ready CLI Workflow: Generates exact systemctl daemon-reload, enable, start, status, and journalctl logging commands.
Multi-Framework Presets: Quick one-click templates for Node.js/Next.js, Python Gunicorn/FastAPI, Go microservices, and Docker daemons.
File Descriptor Limits: Pre-configures LimitNOFILE=65535 to prevent "Too many open files" errors under heavy traffic.
Zero Telemetry: Executed 100% client-side in the browser. File paths, user accounts, and secret environment names remain private.

Frequently Asked Questions
- Where do systemd service unit files live on Ubuntu and Debian?
- System-wide systemd service unit files should be placed in /etc/systemd/system/<service-name>.service. After creating or editing the file, always run "sudo systemctl daemon-reload" to reload the unit configuration.
- Why should I enable systemd hardening directives like NoNewPrivileges and ProtectSystem?
- Hardening directives use Linux kernel cgroups and namespaces to isolate your daemon. "NoNewPrivileges=true" blocks setuid privilege escalation, while "ProtectSystem=strict" mounts /usr, /boot, and /etc as read-only, preventing attackers from modifying system binaries even if the application process is compromised.
- What is the difference between Type=simple and Type=exec?
- Type=simple considers the service started immediately after the child process is forked. Type=exec waits until the executable binary has been loaded and initialized, ensuring dependent services do not start before the main daemon binary is running.
- How do I view live logs for my systemd service?
- Use "journalctl -u <service-name> -f" to follow live logs, or "journalctl -u <service-name> -n 100 --no-pager" to view the last 100 log lines.
