SimpleX is a new platform for distributed Internet applications where the privacy of the messages and the network matters most. The current version is stable, robust and can be used from the terminal (command line) on all major desktop platforms (Linux/Mac/Win) and on Android phones in Termux!

There is currently no messaging application that respects user privacy and guarantees metadata privacy โ€” in other words, messages could be private, but a third party can always see who is communicating with whom by examining a central service and the connection graph. SimpleX, at its core, is designed to be truly distributed with no central server. This allows for enormous scalability at low cost, and also makes it virtually impossible to snoop on the network graph.

Host with Server Manager on Windows, or headless Docker (ChatServer + Tor HS). Password rooms are server blind E2EE, so the host cannot derive the room key. Open rooms still encrypt in the browser, but the key is derived from the room ID, creating intentional public channels. Hidden rooms stay off the public list and use invite links. Add a password for private E2EE. Creators get Settings for closed joins, slow mode, lock later, and delete room, plus a Profile recovery code (My Rooms for hidden). Required message TTL, E2EE attachments, and optional Full Vanguards complete the stack.

Server Manager is the host-side control panel: it starts and stops ChatServer plus a Tor v3 Hidden Service, shows the .onion URL to share, optionally enables Full Vanguards, and lets you administer rooms and storage. The host never receives plaintext from clients; password-room keys stay in browsers. Open-room keys are derivable from the room id by design.

Start ChatServer first (Production, waits for /api/health), then enable Tor Copy and share the published .onion URL

Optional Full Vanguards checkbox (Python + Stem) for long-lived HS hardening

Live room list (room id, locked flag, online count only, no message content)

Remove a selected room in realtime: connected users are forced back to the lobby; ciphertext for that room is deleted with secure_delete + VACUUM

Remove SQL data: securely overwrites (then deletes) the SQLCipher DB, WAL/SHM, and db.key.dpapi; optional checkbox also wipes Tor Hidden Service keys (.onion identity)

Generate new address: securely wipes HS keys and publishes a new .onion (chat DB unchanged)

SimpleX chat features and specs

  • End-to-End Encryption
    SimpleX Chat offers end-to-end encryption, ensuring that messages are only readable by the sender and the recipient, providing a high level of privacy and security.
  • Decentralized Messaging
    The platform operates on a decentralized network, meaning there is no central server that could potentially be a single point of failure or monitoring.
  • Open Source
    SimpleX Chat is open-source, allowing users to inspect the code for any vulnerabilities or privacy issues and enabling community-driven improvements.
  • No User Metadata
    The service does not collect or store user metadata, enhancing user privacy and preventing tracking of communication patterns.

Possible disadvantages of SimpleX chat

  • Limited User Base
    As a newer and less mainstream messaging app, SimpleX Chat may have a smaller user base, which could limit its adoption among friends and contacts.
  • Potential Usability Issues
    As with many privacy-focused platforms, users may encounter a more complex setup or interface compared to mainstream messaging apps.
  • Feature Limitations
    It might lack some advanced features offered by larger, established messaging platforms, such as extensive media sharing options or integrations with other services.
  • Network Reliability
    Being decentralized, the performance and reliability of message delivery might vary depending on the network conditions and the number of participating nodes.

OffCode Tor Chat E2EE features and specs

  • Slow mode
    Send cooldown 1 min โ€ฆ 4 h (applies to everyone, including creator)
  • Delete this room

  • Server manager
    Start ChatServer first (Production, waits for /api/health), then enable Tor Copy and share the published .onion URL Optional Full Vanguards checkbox (Python + Stem) for long-lived HS hardening Locks CORS to your onion: TORCHAT_ALLOWED_ONION on start + live POST /api/admin/cors-onion (no ChatServer restart) Live room list (room id, locked flag, online count only, no message content) Remove a selected room in realtime: connected users are forced back to the lobby; ciphertext for that room is deleted with secure_delete + VACUUM Remove SQL data: securely overwrites (then deletes) the SQLCipher DB, WAL/SHM, and db.key.dpapi; optional checkbox also wipes Tor Hidden Service keys (.onion identity) Generate new address: securely wipes HS keys and publishes a new .onion (chat DB unchanged) Point at your ChatServer project path and load/save host config as needed
  • Full Vanguards Guard-Discovery Protection
    A standard Tor Hidden Service chooses its entry (guard) nodes randomly on every circuit build. Over time a network-level adversary can watch which relays the server connects to and gradually narrow down the real server IP. This is called a guard-discovery attack and is especially dangerous for long-lived hidden services.
  • Encryption
    WebCrypto AES-256-GCM; PBKDF2-v2 domains at 600 000 iterations (torchat-join-v2 / torchat-e2ee-v2 locked = server-blind; torchat-open-v2 open = public key material). Envelopes: pbkdf2-v2 / ecdh-hybrid-v1
  • XSS hardening
    No user innerHTML; messages and room ids via textContent / createElement
  • ECDH + safety number
    1:1 hybrid ECDH; safety number from sorted SPKI pubs (3ร—5 decimal); Mark verified / TOFU change warning (sessionStorage)

Analysis of SimpleX chat

It does not require phone numbers or email addresses to sign up, ensuring that users' identities remain private. The platform uses end-to-end encryption and does not store any messages on its servers, further enhancing user privacy. Additionally, the lack of centralized servers eliminates a single point of failure, making it more resilient against attacks.
