SDKs are pieces of software meant for developers, that take care of the technical Matrix protocol calls behind the scenes. They allow them to focus on where they can add the most value. If you're not a developer, this section of the website is probably not for you.

There are two fundamental types of SDKs: clients and appservices. This distinction is quite academical, and we went for a more pragmatic approach. You will find below SDKs by type of product you may want to create (namely: clients, bots, bridges). Don't be surprised if the same SDK appears in several sections!

If you are a developer and are not sure what the difference between clients and appservices is, please head to the developers documentation.

Client SDKs are used to develop clients humans will interact with. They handle all the Matrix heavy lifting and leave it up to the developer to implement a UI.

The SDK can support any of the maturity levels checked.

The client can support any of the licences checked.

The client must support any of the languages checked.
