the best sitemap submitter, indexing a including new pages built?

[timetoplaysomegames]

Hi folks, does anyone have a preference as to what sitemap software to use to make sure all including new pages are indexed, is there a program that enables automatic updates, in other words, if i create a new page, do not want to go through manual submission, would rather it be done automatically?

Any advice is welcome, iv seen a couple, but not really sure what is best, as i add pages i want automatic indexing?

Legend, stay safe.
