GoToSocial provides a lightweight, customizable, and safety-focused entryway into the [Fediverse](https://en.wikipedia.org/wiki/Fediverse), and is comparable to (but distinct from) existing projects such as [Mastodon](https://joinmastodon.org/), [Pleroma](https://pleroma.social/), [Friendica](https://friendica.net), and [PixelFed](https://pixelfed.org/).
Documentation is at [docs.gotosocial.org](https://docs.gotosocial.org). You can skip straight to the API documentation [here](https://docs.gotosocial.org/en/latest/api/swagger/).
Because GoToSocial uses [ActivityPub](https://activitypub.rocks/), you can hang out not just with people on your home server, but with people all over the [Fediverse](https://en.wikipedia.org/wiki/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.
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](https://tusky.app/) and [Pinafore](https://pinafore.social/).
- Built-in, automatic support for secure HTTPS with [LetsEncrypt](https://letsencrypt.org/).
- 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](https://tools.ietf.org/id/draft-cavage-http-signatures-01.html) when sending and receiving messages, to ensure that your messages can't be tampered with and your identity can't be forged.
GoToSocial supports [OpenID Connect (OIDC)](https://openid.net/connect/) identity providers, meaning you can integrate it with existing user management services like [Auth0](https://auth0.com/), [Gitlab](https://docs.gitlab.com/ee/integration/openid_connect_provider.html), etc, or run your own and hook GtS up to that (we recommend [Dex](https://dexidp.io/)).
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](https://github.com/matrix-org/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.
