SimpleX Chat vs VoIP.ms SMS
Side-by-side comparison of two open source alternatives
SimpleX Chat
SimpleX - the first messaging platform that has no user identifiers, not even random numbers! Security assessment was done by Trail of Bits in November 2022. SimpleX Chat features: end-to-end encrypted messages, with editing, replies and deletion of messages. sending end-to-end encrypted images and files. single-use and long-term user addresses. secret chat groups - only group members know it exists and who is the member. end-to-end encrypted audio and video calls. private instant notifications. portable chat profile - you can transfer your chat contacts and history to another device (terminal or mobile). SimpleX Chat advantages: Full privacy of your identity, profile, contacts and metadata: unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers. Complete protection against spam and abuse: as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. Full ownership, control and security of your data: SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. Decentralized network: you can use SimpleX with your own servers and still communicate with people using the servers that are pre-configured in the apps or any other SimpleX servers. You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed. Your profile and contacts are only stored in the app on your device - our servers do not have access to this information. All messages are end-to-end encrypted using open-source double-ratchet protocol; the messages are routed via our servers using open-source SimpleX Messaging Protocol.

VoIP.ms SMS
Overview VoIP.ms SMS is an Android messaging app for VoIP.ms that seeks to replicate the aesthetic of Google's official SMS app. Features • Material design • Push notifications (if using the Google Play version of the app) • Synchronization with device contacts • Message search • Comprehensive support for synchronization with VoIP.ms • Completely free Rationale A number of people use VoIP.ms as a cheaper alternative to subscribing to a voice plan for their mobile devices. Unfortunately, this can make sending text messages rather difficult, as the VoIP.ms SMS Message Center is clearly built as a diagnostic tool for use in desktop browsers, not as an easy way to send and receive messages on a mobile device. VoIP.ms does provide a mobile version of this interface with an improved UI, but it still lacks important features that are only possible with a dedicated app. Installation The standard version of the app uses closed-source Firebase libraries to support push notifications and facilitate crash reporting and analytics, among other purposes. A version of the application that is completely open source is available from F-Droid. Both versions are available from the Releases section of the GitHub repository. Documentation The app's documentation is available in the HELP.md file. License VoIP.ms SMS is licensed under the Apache License 2.0.
