One product. One licence. A threshold, not a crippled edition.
There is no community version on one side and a real version on the other. There is OxiMail, and a line: five users. Below it, for an organisation running OxiMail for itself, everything you see here is free — including the client applications. Above it, or the moment you operate OxiMail for other people, you buy a licence. Either way it runs on your infrastructure, in your jurisdiction, and nobody else holds the keys.
What is free, and what is not.
| What you get | Community | Pro |
|---|---|---|
| Who it is free for | An organisation running OxiMail for itself, five users or fewer. Aliases, distribution lists and shared mailboxes without their own login do not count. | Above five users. And from the first mailbox for a hoster or a managed-services company operating OxiMail for third parties. |
| Licence | The OxiMail License, a fair-source licence. Every release becomes AGPL-3.0-or-later four years after it ships. | The same licence, with a paid grant. The four-year conversion applies just the same. |
| Mail, calendar, contacts, tasks, files, chat | Complete | The same engine |
| Client applications | Workspace (web) and Sync (desktop), included | The same applications |
| Anti-spam | Three-stage scored pipeline (network, content, per-tenant Bayesian model), built in | A neural model swaps into the model stage · Shield, on the roadmap: attachment scanning, link protection, BEC detection |
| Storage & scale | SQLite — validated to about 2000 accounts per instance | PostgreSQL, object storage, clustering — built as customers fund them |
| Directory | — | LDAP and directory integration |
| Modules | — | AI assistant and Meet, available · Booking and Notify, in development · Comms and Shield, roadmap |
| Support | The public documentation | Commercial support bundles |
| Who operates it | You | You — paying does not move your data anywhere |
Nothing is taken out of the free tier to create the paid one. Below five users you get the complete suite, client applications included, which is more than the earlier open-source plan ever offered. Above the line you are paying for scale, for optional modules, and for someone to answer the phone.
Three ways to read the rest.
The products
Workspace, Sync, Drive and every module, with honest status.
