Miiverse Custom Image Tool Custom 3DS homebrew that allows you to post custom screenshots to Miiverse.
Since this uses the 3DS's screen to display images, your images have to be either 400x240 or 320x240 to work, and in PNG format. More details on how to use this can be found in the GBATemp thread.
Note that this has been replaced by our new method to access 3DS/Wii U Miiverse from PC, and you can post higher-quality images as well as custom videos and more stuff using that instead. I won't be providing support for this anymore.

Yeahbot iMacros script that allows you to automatically yeah posts on Miiverse.
This only works with the Chrome version of iMacros, as Firefox blocks running JavaScript as URLs, which is needed to press all the yeah buttons.
Note that this macro has been replaced by the Tampermonkey script Yeahbot+, which can be found below. I won't be providing support for this anymore.

Miiverse+ Tampermonkey script that adds some new features to Miiverse.
Eventually there'll be a Chrome extension you can install much more easily, but until then this is all we have.

Yeahbot+ Tampermonkey script that allows you to automatically yeah posts on Miiverse.
To run it, just install the script, turn on the switch, and new Miiverse pages will include a button that will automatically refresh and yeah all posts.
You can yeah multiple communities by running this in multiple tabs, and you can even do other things in the background.
