Olvid vs Wire

Olvid is an instant messaging app for text messages and attachments, available on Android, iOS, Linux, macOS, web, and Windows. Olvid says it does not require identifying details such as a phone number, email, name, address, or birth date. It also says messages and metadata are end-to-end encrypted, so it cannot know who is communicating with whom. Each message and file uses a single-use ephemeral key, intended to protect message history if a key is compromised. The app supports synchronization across devices without a master device. Secure audio and video calls are end-to-end encrypted; video calls support up to two contacts, while group audio calls have no participant limit. Receiving calls is free, and initiating them is free during a one-month trial that ends without billing or automatic subscription. The free plan includes unlimited messages and attachments, group discussions, ephemeral messages, multiple profiles, and inbound calls. Business costs €990 a year; Enterprise costs €990.50 a year.

Wire is a communications platform for organizations that combines messaging, calls, conferencing, and file sharing with end-to-end encryption. Messages support group conversations, search, sketches, reactions, shared files, and audio and video messages. Conferences support up to 150 participants, with screen sharing and moderation tools. File management and online document collaboration keep files in conversations tied to verified group membership. Wire says only conversation participants can decrypt messages, calls, and files. It lists ISO 27001, ISO 27701, and Cyber Essentials certifications, and says its servers are in Germany and Ireland. Organizations can choose cloud, private cloud, or on-premises deployment, including offline or air-gapped environments. Wire is available on web, Windows, macOS, Linux, iOS, and Android; its Linux binary is described as experimental with community support. The free plan is for up to five people. Wire for SMB costs €7.45 per person/month with annual payment, or €8,94 per person/month with monthly payment.
