RSSme

RSSme: A free, small, and intuitive RSS editor

RSSme is a free and lightweight piece of software that enables you to easily create and edit RSS feeds. Creating and managing posts is extremely simple thanks to the dockable bar.

The posts editor lets you customize your posts in a visual manner and you can use plain HTML tags, including A, B, I, U, and S, among others.

RSSme also allows you to insert images in WYSIWYG mode, and the HTML code can be previewed on-the-fly.

It’s also worth noting the program is able to quickly validate RSS feeds using the W3C official website.
