Welcome to Hollo

For single-users

Hollo is designed for single-users, so you can own your instance and have full control over your data. It’s perfect for personal microblogs, notes, and journals.

Multiple accounts

Although Hollo is designed for single-users, you can have multiple accounts on the same instance. You can switch between accounts easily, and each account has its own profile, posts, and settings.

Mastodon-compatible API

Hollo is headless; instead, it complies with the Mastodon API, so that you can use any Mastodon-compatible client to interact with it.

CommonMark

You can compose your posts in CommonMark (so-called Markdown), and Hollo will render them for you—of course, other fediverse software will render them as well. Moreover, you’re allowed up to 4,096 characters per post.

Misskey-style quotes

Hollo supports Misskey-style quotes, so you can quote other posts in your own posts. It’s compatible with other fediverse software that supports Misskey-style quotes, e.g., Misskey, Akkoma, Fedibird, Threads.

Powered by Fedify & Bun

Hollo is powered by Fedify, an ActivityPub server framework for TypeScript. It’s built on top of Bun, an alternative super-fast JavaScript runtime to Node.js.
