HT Mega (Absolute Addons for Elementor) is a feature-packed Elementor companion plugin that adds a large library of 135–137+ widgets, plus a theme builder, so you can build more complex layouts without custom code. It also comes with a big starter library of ~795–798+ ready blocks and 245+ page templates to speed up page building. Their pricing page highlights plans like Personal ($49/year for 1 site) that include the full widget/module/template set and an AI Writer feature. The plugin is available on WordPress.org and can be used with Elementor Free (with some advanced features typically aimed at Pro users).
