ZWEIG Chat

ZWEIG Chat is a secure, self-hosted messenger for teams and organizations. Your company runs its own server, so all conversations, files and calls stay under your control — not on someone else's cloud.

KEY FEATURES

• Private one-to-one and group chats
• Channels for teams, projects and departments
• High-quality voice and video calls
• Share photos, videos, documents and files
• Message reactions and replies
• Push notifications so you never miss a message
• Clean, fast and simple interface

BUILT FOR PRIVACY

ZWEIG connects only to your organization's own server. Accounts are created by your administrator — there is no public sign-up. All traffic is encrypted in transit (HTTPS/TLS), and your data lives on infrastructure you own and manage.

FULL CONTROL

• Self-hosted: keep 100% of your data in-house
• Admin tools to manage members and channels
• Delete your account any time from the app

GETTING STARTED

To use ZWEIG Chat you need access to a ZWEIG server provided by your organization. On first launch, enter your server address, then sign in with the credentials given by your administrator.

ZWEIG Chat is ideal for companies, teams and communities that value privacy and want a messaging platform they fully own.
