Upcoming Conference

Cloud Native & Open Source Conference In London

June 2025

A practitioner-led conference for cloud native builders, SREs, platform teams, and open source engineers.

Why now

Communities already shape critical social and technical infrastructure, but remain fragmented, hard to discover, and under-supported.

The next decade requires trusted networks built for participation, safety, learning, and long-term resilience.

Community Stack exists to steward that infrastructure responsibly and build systems designed to endure.

Operating principles

Infrastructure-first
Stewardship before scale
Trust by design
Global vision, local agency
Impact over activity
Open where possible, responsible where necessary

Stewardship-led, governance-first.

We build continuity, accountability, and resilience into the systems communities rely on, prioritising long-term ecosystem health over short-term optimisation.
