Feedit is a native macOS editor for creating, managing, and publishing RSS 2.0 feeds. Import existing feeds from files or URLs, edit every field with a syntax-highlighted HTML description editor and live preview, then publish to a local folder or WebDAV server. A built-in validator checks feeds against the RSS spec with error and warning indicators. Feeds sync across devices via iCloud with conflict resolution. Draft support lets you prepare items before publishing, and credentials are stored securely in the Keychain. Find and Replace, Undo, and keyboard shortcuts are all built in. Under 2 MB.
