Element
Element is an open source messaging and collaboration platform.
We give people and organisations back their digital sovereignty by decentralising conversations, letting you host yourself or through a hosting provider such as Element Matrix Services.

Additional privacy is provided by end-to-end encryption, protecting instant messaging, 1:1 voice and video calls, and file sharing.
Element was founded by the team behind Matrix as a way to bring it to the mainstream.

Mozilla
Mozilla is the non-profit backed technology company that champions privacy, human dignity, and an open internet. Our mission is to ensure the internet is a global public resource, open and accessible to all.
We have been pioneering stakeholder capitalism in tech for the past 25 years. Our next quarter century will be about continuing to do more, from helping build responsible tech products to growing the community, thanks to new talent that truly cares about making the internet better.
The web should put people first — and be open to everyone, empowering and safe. It should be a place that revels in the independent spirit, allows for connection and community building, and to express yourself in your most authentic way.
That’s why we created Firefox as a faster, more private browser alternative.
Firefox offers a choice in the marketplace — a people-first independent choice. It allows users to be their authentic self online while at the same time supporting an independent, nonprofit-backed browser whose mission is to build a better internet.
