Private communication infrastructure you control
DeltaChat simplifies the process of bringing up a private Matrix-based communication system — including a ready-wired Element Web experience — so you can run serious chat infrastructure without fighting through every setup step by hand.
Built on PostgreSQL, .NET 8, Next.js, Nginx Proxy Manager, and Docker Compose.

What Matrix gives you
Matrix is an open communication protocol designed for decentralised, federated, and self-hostable messaging. In simple terms, it gives you a way to run communication infrastructure under your own control rather than relying entirely on a single vendor’s platform.
DeltaChat is valuable because it makes that model more practical. Instead of expecting operators to assemble and wire the whole environment from scratch, it brings the key pieces together into a cleaner deployment path.
Why DeltaChat matters
Simplifies Matrix deployment
DeltaChat reduces setup friction by automating and wiring up the parts that are often awkward for first-time operators.
Element Web ready to go
The communication environment is provisioned with Element Web already integrated, so you do not need to manually solve that wiring first.
Improves onboarding
Guest chat features help reduce one of the harder parts of adoption: getting people into the system quickly and simply.
Why Matrix matters
Most people already understand chat apps. Fewer understand Matrix. But Matrix is a large part of what makes DeltaChat important.
It gives organisations, communities, and privacy-conscious operators a different model for communication — one built around open standards, federation, self-hosting, and stronger infrastructure control.
DeltaChat helps make that model practical by reducing the setup and deployment complexity that often stops people from adopting it.
Open communication model
Matrix is not just one vendor’s messaging app. It is an open protocol with a broader communication ecosystem behind it.
Self-hosting and control
You can run the communication environment on infrastructure you control instead of relying entirely on a centralised provider.
Why DeltaChat helps
DeltaChat lowers the barrier by wiring together the key parts of a Matrix-based setup into a cleaner deployment path.
Core product strengths
DeltaChat is aimed at people who want the control benefits of Matrix, but with a more approachable deployment and operational starting point.
Matrix made practical
DeltaChat simplifies the setup of a Matrix-based communication system so people can deploy private chat infrastructure without having to wire every moving part together manually.
Self-hosted deployment
Run the stack on infrastructure you control using Docker Compose with a deployment model designed to be easier to understand and operate.
Element Web already wired up
DeltaChat provisions the communication stack with Element Web ready to go, reducing one of the more awkward setup steps for new Matrix operators.
Private by design
The system is intended for people and organisations who want ownership over their own communication environment rather than relying entirely on third-party platforms.
Guest chat onboarding support
DeltaChat includes guest chat flows to help reduce onboarding friction, especially where browser-first access matters.
Built on a serious stack
The current system is built on PostgreSQL, .NET 8, Next.js, Nginx Proxy Manager, and Docker Compose as part of a practical, full-stack deployment model.
Who it’s for
DeltaChat is intended for people and organisations who want private communication infrastructure that they can own, operate, and understand.
