Session review
A privacy-focused messenger with broad platform support and a 10 MB attachment limit.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Session is a decentralized messaging app for private, pseudonymous communication. It supports end-to-end encrypted one-to-one messaging, group chats, disappearing messages, encrypted attachments, and peer-to-peer voice and video calls. Accounts use pseudonymous Account IDs instead of phone numbers or email addresses. With clients for Android, iOS, Windows, macOS, and Linux, Session suits people who want anonymous communication across mobile and desktop devices. It is open source and stewarded by the Session Technology Foundation.
Privacy is the product’s central focus. Onion-routed message delivery, community-operated decentralized message storage, and disappearing messages add layers of privacy-oriented functionality. Users can also create groups, use custom themes and emoji reactions, and make voice or video calls. The published category details list group support for up to 100, while encrypted file attachments are capped at 10 MB. Session’s encryption model is mixed, so buyers should distinguish its combination of encrypted messaging and onion routing from a single uniform encryption approach across every function.
The Free plan includes end-to-end encrypted messaging, encrypted attachments up to 10 MB, onion routing, and account creation without a phone number. Pro costs $2.99 USD per month and adds messages up to 10,000 characters, unlimited pinned conversations, animated display pictures, and a supporter badge. Session is a strong fit for users prioritizing pseudonymous accounts, onion-routed delivery, and broad device coverage. It is less suitable for people who need larger file transfers, a uniform encryption model, or advanced paid features without a subscription.
