mastodon
v4.3.1
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, and 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!)

It doesn't have to be Mastodon; whatever implements ActivityPub is part of the social network! Learn more
Updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!
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!
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
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!
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 12+
Redis 4+
Ruby 3.2+
Node.js 18+
The repository includes deployment configurations for Docker and docker-compose as well as specific platforms like Heroku, and Scalingo. For Helm charts, reference the mastodon/chart repository. The standalone installation guide is available in the documentation.
A Vagrant configuration is included for development purposes. To use it, complete the 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 && bin/dev"
Open http://mastodon.local in your browser
To set up macOS for native development, complete the following steps:
Install Homebrew and run brew install postgresql@14 redis imagemagick libidn nvm to install the required project dependencies
Use a Ruby version manager to activate the ruby in .ruby-version and runnvm use to activate the node version from .nvmrc
Run the bin/setup script, which will install the required ruby gems and node
packages and prepare the database for local development
Finally, run the bin/dev script which will launch services via overmind(if installed) or foreman
For production hosting and deployment with Docker, use the Dockerfile anddocker-compose.yml in the project root directory.
For local development, install and launch Docker, and run:
docker compose -f .devcontainer/compose.yaml up -d docker compose -f .devcontainer/compose.yaml exec app bin/setup docker compose -f .devcontainer/compose.yaml exec app bin/dev
Within IDEs that support the Development Containers specification, start the
"Mastodon on local machine" container from the editor. The necessary docker compose commands to build and setup the container should run automatically. ForVisual Studio Code this requires installing the Dev Container extension.
GitHub Codespaces provides a web-based version of VS Code and a cloud hosted development environment configured with the software needed for this project.
Click the button to create a new codespace, and confirm the options
Wait for the environment to build (takes a few minutes)
When the editor is ready, run bin/dev in the terminal
Wait for an Open in Browser prompt. This will open Mastodon
On the Ports tab "stream" setting change Port visibility → Public
