**Element Synapse - Matrix homeserver implementation**
|support| |development| |documentation| |license| |pypi| |python|
Synapse is an open source `Matrix <https://matrix.org>`__ homeserver
implementation, written and maintained by `Element <https://element.io>`_.
`Matrix <https://github.com/matrix-org>`__ is the open standard for secure and
interoperable real-time communications. You can directly run and manage the
source code in this repository, available under an AGPL license (or
alternatively under a commercial license from Element).
There is no support provided by Element unless you have a subscription from
Element.
🚀 Getting started
==================
This component is developed and maintained by `Element <https://element.io>`_.
It gets shipped as part of the **Element Server Suite (ESS)** which provides the
official means of deployment.
ESS is a Matrix distribution from Element with focus on quality and ease of use.
It ships a full Matrix stack tailored to the respective use case.
There are three editions of ESS:
- `ESS Community <https://github.com/element-hq/ess-helm>`_ - the free Matrix
distribution from Element tailored to small-/mid-scale, non-commercial
community use cases
- `ESS Pro <https://element.io/server-suite>`_ - the commercial Matrix
distribution from Element for professional use
- `ESS TI-M <https://element.io/server-suite/ti-messenger>`_ - a special version
of ESS Pro focused on the requirements of TI-Messenger Pro and ePA as
specified by the German National Digital Health Agency Gematik
