GoToSocial
GoToSocial is an ActivityPub social network server, written in Golang.
GoToSocial provides a lightweight, customizable, and safety-focused entryway into the Fediverse, and is comparable to (but distinct from) existing projects such as Mastodon, Pleroma, Friendica, and PixelFed.
With GoToSocial, you can keep in touch with your friends, post, read, and share images and articles. All without being tracked or advertised to!
Documentation is at docs.gotosocial.org. You can skip straight to the API documentation here.

Features
Federation
Because GoToSocial uses ActivityPub, you can hang out not just with people on your home server, but with people all over the Fediverse, seamlessly.
Federation means that your home server is part of a network of servers all over the world that all communicate using the same protocol. Your data is no longer centralized on the servers of one gigantic corporation, but resides on your own server and is shared -- as you see fit -- across a resilient web of other home servers.
Mastodon API compatible
The Mastodon API has become the de-facto standard for client communication with federated servers, so GoToSocial has implemented and extended the API with custom functionality.
This means: full support for modern, beautiful apps like Tusky and Pinafore.

If you're used to using Mastodon, you'll find using GoToSocial a breeze.
Granular post settings
It's important that when you post something, you can choose who sees it.
GoToSocial offers public/unlisted/friends-only/mutuals-only/and direct posts (slide in DMs!).
It also allows you to customize how people interact with your posts:
- Local-only posts.
- Rebloggable/boostable toggle.
- 'Likeable' toggle.
- 'Replyable' toggle.
Easy customizability for admins
Lots of config options, including:
- Adjustable post length.
- Media upload size settings.
Easy to run
No external dependencies apart from a database (or just use SQLite!). Simply download the binary + assets (or Docker container), and run.
Plays nice with lower-powered machines like Raspberry Pi, old laptops and tiny VPSes.
Safety + security features
- Built-in, automatic support for secure HTTPS with LetsEncrypt.
- Strict privacy enforcement for posts and strict blocking logic.
- Import and export allowlists and denylists. Subscribe to community-created blocklists (think Adblocker, but for federation!).
- HTTP signature authentication: GoToSocial requires HTTP Signatures when sending and receiving messages, to ensure that your messages can't be tampered with and your identity can't be forged.
Various federation modes
GoToSocial doesn't apply a one-size-fits-all approach to federation. Who your server federates with should be up to you.
- 'Normal' federation; discover new servers.
- Allowlist-only federation; choose which servers you talk to.
- Zero federation; keep your server private.
OIDC integration
GoToSocial supports OpenID Connect (OIDC) identity providers, meaning you can integrate it with existing user management services like Auth0, Gitlab, etc, or run your own and hook GtS up to that (we recommend Dex).
Wishlist
These cool things will be implemented if time allows (because we really want them):
- Groups and group posting!
- Reputation-based 'slow' federation.
- Community decision making for federation and moderation actions.
- User-selectable custom templates for rendering public posts:
- Twitter-style
- Blogpost
- Gallery
- Etc.
Design Ethos
One of the key differences between GoToSocial and other federated server projects is that GoToSocial doesn't include an integrated client front-end (ie., a webapp).
Instead, like Matrix.org's Synapse project, it provides only a server implementation, some static pages, and a well-documented API. On top of this API, developers are free to build any front-end implementation or mobile application that they wish.
Because the server implementation is as generic and flexible/configurable as possible, GoToSocial provides the basis for many different types of social media experience, whether Tumblr-like, Facebook-like, or Twitter-like.
Status
Work began on the project around February 2021, and the project is still in prerelease.
At this point, GoToSocial is already deployable and very useable, and it federates cleanly with most other Fediverse servers (not yet all).
For a detailed view on what's implemented and what's not, and progress made towards a first v0.1.0 (beta) release, see here.
Getting Started
Proper documentation for running and maintaining GoToSocial will be forthcoming in the first release.
For now (if you want to run it pre-alpha, like a beast), check out the quick and dirty getting started guide.
