Misskey (Japanese: ミスキー) is self-hosted social networking software.[2][3][4][5] It is commonly used as part of the Fediverse network, with Mastodon and similar software.

Misskey was created in 2014 by Eiji "syuilo" Shinoda[6], a Japanese software engineer.[7] The main service was first developed as a bulletin board, but then the open-source community started to add short "Notes" and a timeline function to the service growing it into a microblogging site. ActivityPub functionality was added in April 2018,[8] allowing Misskey servers to join the Fediverse.

A user's post is called a Note. As with other open-source social networks, users can join or create servers. Each server is managed by different administrators, in different locations.

The origin of the Misskey name is from the lyrics of 'Brain Diver' [ja], a song released by the Japanese singer May'n.[7]

## Development[edit]

Misskey is open source software licensed under the AGPLv3\. Since Misskey also publishes open API, you can create a personal application through the code. The translation uses Crowdin.

Misskey was also targeted in a spam attack in 2024.[9]

## Technology[edit]

The code is written with TypeScript and Node.js. PostgreSQL is used as a database software while Vue.js is used as the Web client since February, 2018. Misskey users can interact with users on any other server that supports ActivityPub.

## Differences from Mastodon[edit]

Misskey and Mastodon are both distributed social networks based on ActivityPub and users can communicate both ways as part of the Fediverse network. Their codebases are unrelated, so there are differences in APIs and interpretations of ActivityPub.

When it began, Misskey was not designed as a distributed social network, so its main philosophy is not based on an decentralized approach.[10]

## Relation with other social networks[edit]

As a decentralized social networking service, like Mastodon, it has gradually gained attention as a transitional destination from Twitter, one of the centralized social networking services.

In July 2023, as X incorporated extreme API restrictions on the number of reads for scraping, the same users, whose activities were narrowed down, migrated to other decentralized SNSs, Misskey's largest server, "Misskey.io", and other servers in Misskey. The number of users registering on Misskey.io, Misskey's largest server, has increased rapidly.[11][12]

In response to this trend, Skeb, announced on July 14, 2023 that it would sponsor the Misskey development team.[13]

## Forks[edit]

* Firefish (formerly Calckey), developed by ThatOneCalculator.[15][16]
* Iceshrimp, forked from Calckey in 2023.
* Sharkey, developed by Transfem.org.[17]
