About this app

Diode Collab is a zero trust collaboration app for teams. It includes messaging, file sync, and tunneled web browsing. None of your data or communications are ever stored on a server - all information and identities are self-custody.

Create security Zones in seconds, invite team members to collaborate, and add files & IT/OT assets to collaborate around. Enable share links to cherry-pick specific content to share/upload via password protected web browser link.

Works in concert with Diode's CLI tool (headless tool for asset connectivity).

Ratings and reviews

What’s good! Really cool idea: secure comms as open infrastructure, not just another chat app. Strong security-first approach (E2EE, self-custody, no central servers). More than messaging — the CLI + network make it feel powerful for devs and ops teams. Love the option to run your own infra or even use the Vault hardware. Feels perfect for security-focused teams, field ops, and DevOps.

Solid secure messaging app. No servers, no accounts, and end-to-end encryption by default. Feels like Slack/Discord but without the privacy tradeoffs. Worth checking out if security matters to you.

Great for secure communication from anywhere at any time.
