Version Control

This is a rebase fork of tootsuite/mastodon, all local changes are rebased on the top. To pull the latest commits of this repo, use git reset --hard origin/main instead of git pull. If you are going to develop based on this fork, I strongly recommend you always cherry-pick your commits to the HEAD of this branch.

Enable Custom Features

To enable the new custom features, please add the necessary configurations first according to the file end of .env.production.sample.

This project added the Chinese words segmentation support in ElasticSearch, please use this ElasticSearch image. Using the original version of ElasticSearch Engine may goes into error.

GitHub release Build Status Code Climate Crowdin Docker Pulls

Mastodon is a free, open-source social network server based on ActivityPub where users can follow friends and discover new ones. On Mastodon, users can publish anything they want: links, pictures, text, video. All Mastodon servers are interoperable as a federated network (users on one server can seamlessly communicate with users from another one, including non-Mastodon software that implements ActivityPub)!

No vendor lock-in: Fully interoperable with any conforming platform

It doesn't have to be Mastodon; whatever implements ActivityPub is part of the social network! Learn more

Real-time, chronological timeline updates

Updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!

Media attachments like images and short videos

Upload and view images and WebM/MP4 videos attached to the updates. Videos with no audio track are treated like GIFs; normal videos loop continuously!

Safety and moderation tools

Mastodon includes private posts, locked accounts, phrase filtering, muting, blocking and all sorts of other features, along with a reporting and moderation system. Learn more

OAuth2 and a straightforward REST API

Mastodon acts as an OAuth2 provider, so 3rd party apps can use the REST and Streaming APIs. This results in a rich app ecosystem with a lot of choices!


Tech stack:

  • Ruby on Rails powers the REST API and other web pages
  • React.js and Redux are used for the dynamic parts of the interface
  • Node.js powers the streaming API


  • PostgreSQL 9.5+
  • Redis 4+
  • Ruby 2.6+
  • Node.js 14+

The repository includes deployment configurations for Docker and docker-compose as well as specific platforms like Heroku, Scalingo, and Nanobox. The standalone installation guide is available in the documentation.

A Vagrant configuration is included for development purposes. To use it, complete following steps:

  • Install Vagrant and Virtualbox
  • Install the vagrant-hostsupdater plugin: vagrant plugin install vagrant-hostsupdater
  • Run vagrant up
  • Run vagrant ssh -c "cd /vagrant && foreman start"
  • Open http://mastodon.local in your browser
