Frequently Asked Questions
? Is Misskey hard to install?
Misskey offers Docker deployment which simplifies setup for most users, with step-by-step guides available. Non-Docker setups require Node.js and PostgreSQL knowledge, but community documentation and support help ease the process.
? Is it a good alternative to Twitter/X?
Yes—Misskey supports short-form posts, media sharing, and threads like Twitter/X, but with federation (no single owner) and better privacy. It lacks the massive user base but gives users/ admins more control over their experience.
? Is it completely free?
Misskey is open-source (MIT License) and free to use, self-host, or modify. Core features have no cost; some third-party instances may accept donations for hosting, but no paid tiers exist for essential functionality.
