Nebulynk

Nebulynk is a self-hosted collaboration platform combining team chat, persistent voice channels, and video meetings in a single workspace. It's designed for teams wanting modern communication without surrendering control over data, infrastructure, or AI provider choices. The platform includes channels, direct messages, file sharing, search, voice and video capabilities, screen sharing, meeting transcription, and AI-powered summaries through a bring-your-own-key model.

All core features are available in the free tier under the Business Source License; there are no artificial feature gates or premium editions. The project was built with Claude Code and ships with Docker-based deployment resources for practical self-hosting. Access is secured via passwords, passkeys, WebAuthn, and optional two-factor authentication.
