Why Zerta?

We run our own XMPP server (a hard fork of Jackal) with all the modern XEPs other providers don't offer.

SASL2 + Bind2 + FAST

Single-round-trip auth + token-based reconnects. Mobile clients save battery and bandwidth.

MAM + Occupant-ID

Stable Message Archive pagination, MUC identity preserved across resource changes. No more broken history.

EU Hosting, GDPR

Hetzner Germany/Finland. No US cloud, no third-country data transfers. Contract & DPA included.

Open Source

Server code under Apache 2.0. git.uuxo.net/UUXO/zerta · Migratable, no vendor lock.

Anti-Spam & MUC RTBL
