Core benefits
Built around the fundamentals that matter
DeltaChat focuses on the fundamentals that matter most in self-hosted environments: control, clarity, deployability, and predictable runtime behavior.
Self-hosted by design
Run DeltaChat on infrastructure you control, with deployment centered on your environment, not a vendor control plane.
Open source under AGPLv3
Source-available and positioned for serious self-hosted use, with licensing aligned to operator-facing deployment.
No hidden telemetry
Trust should come from documented behavior, observable runtime activity, and clear network expectations.
Practical install path
A direct operator-first setup flow built around Docker Compose, staged startup, and explicit infrastructure requirements.
Operator-friendly runtime
Built for environments where logs, ingress, certificates, and deployment boundaries need to be understood clearly.
Private by design
Communication infrastructure for teams that want more control over data, runtime behavior, and operational ownership.
