What is Misskey?

Misskey is social media software for hosting a microblogging instance of your own. Each installation is a separate server, and because the platform is federated, people on one instance can interact with accounts hosted elsewhere rather than staying inside a single closed site. The repository ships a Docker setup whose compose file pairs the application with PostgreSQL for data and Redis. Its interface is counted at 34 languages, with translation work coordinated through Crowdin. The project dates back to 2016 and is published by the misskey-dev organization.

Good fit if

  • You want a community timeline under your own rules and domain rather than an account on a paid or ad-funded network.
  • Your users should reach people on other federated servers, not only each other.
  • You are comfortable running a Docker deployment backed by PostgreSQL and Redis.

Look elsewhere if

  • You want the most widely used ActivityPub microblogging server, with a larger set of compatible apps: Mastodon.
  • Your community is organized around link sharing and voting in topic groups: Lemmy.
  • You need a classic forum with long threads instead of a timeline: Discourse.

Before you adopt it

Misskey uses the AGPL license, which obliges anyone running a modified copy for others over a network to share the changed source. It began under MIT and moved to AGPL-3.0 in March 2018. No paid parts or contributor agreement turn up in the repository. Development is busy, with 180 commits from 15 authors over the last 90 days, though one person wrote about 69 percent of them. Releases follow a date-based scheme; the newest is 2026.10.1 from October 2026.
