Klark and Klara Launch Self-Hosted Corporate Messenger and Task Manager for On-Premise Data Control

Klark and Klara are two integrated products designed to keep corporate communication and task management entirely within company infrastructure. Klark functions as a Telegram-like messenger with personal chats, supergroups, channels, voice messages, file sharing, and video calls powered by LiveKit. Klara serves as a streamlined task and knowledge base system replacing complex setups like Jira and Confluence. Both run via Docker Compose on customer servers using PostgreSQL, Redis, FastAPI, and React, with built-in antivirus scanning via ClamAV. Key security measures include mandatory TOTP two-factor authentication, LDAP integration, content security policies, and automatic session invalidation on token reuse. The combination allows direct task creation from chat messages and displays tasks alongside conversations in a unified interface.
