What is Kumbukum, open source memory infrastructure for teams?
Kumbukum is an open source memory infrastructure designed to help teams store, organise, and retrieve shared knowledge efficiently. Rather than letting important information scatter across emails, chat messages, and documents, Kumbukum acts as a centralised knowledge base where teams can document decisions, processes, lessons learned, and project context. It's built for organisations that want to reduce repetitive questions, onboard new members faster, and maintain institutional memory without relying on proprietary cloud services. Being open source means you can self-host it, customise it to fit your workflow, and maintain full control over your team's data.
