Talk-OS

talk-os is an open-source team chat platform that delivers real-time messaging, channels, and file sharing for collaborative work. It organizes conversations into public rooms and private groups, supports mentions and notifications, and provides a persistent message history with search so teams can catch up quickly. The system is designed around live updates, pushing new messages and presence changes to connected clients without page reloads. File attachments, emojis, and basic rich content previews make day-to-day communication more expressive while keeping the interface clean. Because it’s self-hostable, organizations can run it on their own infrastructure and customize authentication, integrations, and UI behavior to match internal policies. Its architecture demonstrates a typical modern chat stack with a JavaScript front end and a real-time backend, suitable for small companies and hobby teams that want Slack-style workflows without a hosted dependency.
