Feather Wiki has a few different builds with different functionality depending on what you're looking for, each with its own cute bird name to indicate its file size.

All builds of Feather Wiki 1.3.1 and up are built to run on browsers that support ECMAScript 2015 (also known as "ES6"). The differences between each build comes in the form of your choice of content editor. This page will explain all of the differences between each version.

Before we begin, it is worth noting that all content you create in any version can be transferred to any other version using the [[Import & Overwrite button|upgrading]] in the Wiki Settings!

Dove

Dove is the "standard" version of Feather Wiki coming in at about 64.8 kilobytes and containing both the what-you-see-is-what-you-get (WYSIWYG) page editor and a Markdown editor with a toggle switch.

Finch

Finch is smaller than Dove because it only includes the WYSIWYG page editor and not the Markdown one.

Chickadee

Chickadee is tiny because it only includes the Markdown editor.

Server Builds

Coming July/August 2022!

Legacy Builds

The following builds were introduced in version 1.2.0, but it didn't make a lot of sense to keep them around for version 1.3.0 because the size difference wasn't really that remarkable, and the fact that only the newest possible browsers could run them made them a bit less useful.

But the builds will remain here in their unchanged and flawed 1.2.1 versions for nostalgia's sake.

Robin

Robin is like Dove, but a little bit smaller and a little bit less friendly. It has both the WYSIWYG page editor and the Markdown editor, but it only runs on new browsers that support JavaScript features as new as ECMAScript 2020. This is the best choice if you want to switch between editors and plan to use Feather Wiki on newer browsers for wikis you don't plan to share.

Sparrow

Sparrow is smaller than Finch with the same editor, but it's less friendly. As with Robin, only browsers that support JavaScript features as new as ECMAScript 2020 will be able to run Sparrow, but if you only want the WYSIWYG editor and don't plan to share your wiki, then this is your option!

Hummingbird

Hummingbird is the smallest it gets at just 57 kilobytes! Hummingbird only includes the Markdown editor, and as with Robin and Sparrow, it will only run on browsers that support the ECMAScript 2020 features linked above. If you're using a modern browser, don't need to share your wiki, and like writing with Markdown, then this is your best option!
