# Session

Open-source messenger that needs no phone number or email and routes messages through an onion network.

63 points out of 100. #7 of 12 secure messaging apps. Vendor: Session Technology Foundation. Website: https://getsession.org/

- Accounts need no phone number or email; the free tier includes encrypted messages and group chats [1][3].
- Session is free to use; the optional Session Pro starts at $2.99 a month [1][3].
- Apps for Windows, macOS, Linux, iOS and Android; no web app is listed [2].
- Group chats are limited to 100 people [1].
- Voice and video calls are a beta feature, turned off by default [1].

Verdict: Session suits people who want an account with no phone number or email, and open-source apps on desktop and mobile [1][2][5]. Core messaging is free [1][3]. The catch: the only audit it links is from 2021, groups top out at 100 people, there is no web app, and calls are beta [1][2][8]. Best for: People who want an anonymous account and open-source desktop and mobile apps.

Status: Session's FAQ says the Session Technology Foundation, a Swiss foundation, now stewards the project, and the OPTF ended its stewardship in October 2024 [1].
