Systemd Unit Validator
Lint .service, .timer and .socket files for typos and misconfigurations — in your browser, no root.
Paste a unit file and get line-numbered findings: a directive in the wrong section, a typo systemd silently ignores, an OnCalendar= that never fires, Restart= that stops the unit loading at all. Every finding says what systemd itself does about it, and carries the fix. No systemd, no root, no upload.
