Can OBS turn on automatically without third-party add-ons?

[stebbinsd]

If I don't have any third-party mods or add-ons, is vanilla OBS capable of turning on automatically, of its own accord, with or without a schedule?

No, not really. You can use Windows task scheduler to start OBS on user login or on a schedule, with a command line to immediately start streaming. See https://obsproject.com/wiki/Launch-Parameters

However, OBS isn't designed for unattended noninteractive streaming. Ffmpeg as command line tool is better suited for automation.
