<a href="https://wordpress.org/plugins/jetpack/" rel="ugc">Jetpack</a> makes it easy to add contact forms to your WordPress site, but you may want a simple way to add a <a href="https://www.google.com/recaptcha/" rel="nofollow ugc">Google reCAPTCHA</a> to prevent spam. This plugin will manipulate the Jetpack <code>[contact-form]</code> shortcode to prepend the Google script, add a button, and parse the response.
This plugin allows both reCAPTCHA v2 and invisible reCAPTCHA (see screenshots and choose whatever works for you!).

Working on Gutenberg version of Tiled Gallery. Soon, We’ll Release it. Until then, You can use this Tiled Gallery Plugin with Classi WP Editor.
There is no doubt that JetPack packed with tons of features. However, many users don’t want all that monstrous codes in their blog for one or two modules. Also, You should connect your blog to wordpress.com to get the JetPack features.
I really like that Tiled Gallery with Full Screen carousel module in JetPack and don’t want other modules. That’s why I’ve made the this Tiled Gallery Carousel Without JetPack Plugin from JetPack.
Tiled Gallery with carousel will completely transform your galleries to new look and your users will love this. Tiled Gallery allows you to display image galleries in following styles, a rectangular mosaic, a square mosaic, and a circular grid.

Tiled Gallery Carousel Without JetPack

I agree entirely with the premise of this plugin - Jetpack is too bulky and adds bloat to your website.

This plugin does add a CSS file and 2 JS files, but somehow manages to only do it if you're using the gallery on a page. I'm using it, for example, with Advanced Custom fields and while I call the shortcode, that is in my theme...yet the proper CSS and JS files are loaded so the plugin just works, but not loaded on all of the other pages.

So, in short, great plugin.

It gets 4 stars because it adds a menu item in WordPress which is unnecessary and against WordPress best practices. 

See https://codex.wordpress.org/Adding_Administration_Menus#Determining_Location_for_New_Menus

It is rare that a plugin would require the creation of a top-level menu. If the plugin introduces an entirely new concept or feature to WordPress, and needs many screens to do it, then that plugin may warrant a new top-level menu.

This just adds clutter on the backend, but otherwise this plugin is written really well.

Flexible Plugin that is Built Correctly

This is by far my favorite gallery plugin. I love what it does, and I love that I can get it without Jetpack.  Really looking forward to the gutenberg version, it's going to be epic.

Love it like crazy
