FAQ
Do I need to run a server?
Not necessarily. You can sign up on matrix.org or a public homeserver. For privacy or compliance you'd self-host Synapse or Dendrite.
Is the encryption real end-to-end?
Yes — Megolm/Olm cryptography, audited and used in regulated industries. Calls (Element Call) are also end-to-end encrypted.
Can it bridge to Slack or Discord?
Yes — community bridges exist for both, plus Telegram, IRC, and others. Setup takes effort but works.
