What Diode Collab is
Diode Collab combines team messaging, file sharing, and remote access in an app for Android, iOS, Linux, macOS, and Windows. Teams can use direct messages and group channels; messages are described as end-to-end encrypted, enabled by default. Members can collaborate on and sync files, while file backup is available on eligible plans. The pricing page lists unlimited storage and unlimited users across all plans.
Files can be shared using browser upload and download links, including with people who have not installed Diode Collab. The Business plan adds secure equipment access, regional access tunnels, and custom endpoints. New Zones begin on a default free Nomad plan, which users can upgrade in the app. Paid plans are billed per user: Group costs $3 a month, Team costs $10 a month, and Business costs $15 a month. The maker says signup uses pseudonymous identities and requires neither a phone number nor other personally identifiable information. Diode says the app stores no data on servers, distinguishing blockchain membership proofs from stored content. Its About page states ISO 27001 and SOC-2 compliance and displays GDPR and HIPAA alongside those labels. The maker describes the app for teams, families, and organizations, including sensitive or regulated environments.
