Best for email platforms sold through providers
Open-Xchange is the maker of OX App Suite, an email, calendar and documents platform sold to service providers and governments. It publishes no prices and doesn't sell to individuals.
Who Open-Xchange is for
- Fits if you are a hosting provider that wants a branded mail platform
- Works for a public body that wants to run mail on its own servers
Who Open-Xchange is not for
- Skip it if you are one person or a small team, as the site is aimed at providers and the public sector
- Skip it if you want a price before talking to someone
- Not for you if you want a free plan or a trial
- Watch out: the public-sector page says it's most often installed on-premise
Why Open-Xchange gets a 1.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyNo prices are published, so there is nothing to compare. The site sends buyers to a demo.
- FFree plan and trialNothing free is listed. Buyers book a demo or contact sales.
- BFeaturesEmail, calendar, documents, drive, tasks, encryption and an AI agent, all in one suite, with nothing missing from the mail and calendar job.
- CEase of useNo store rating on record. A provider sets it up for you, and what you get depends on who that is.
- CPlatforms and integrationsWeb only on record, with Dovecot Pro, PowerDNS and openDesk as connections. No apps of its own listed.

Keep Open-Xchange, or make your own?
Keep it
To replace Open-Xchange you would be making an email client: sending, receiving, threading and searching years of mail. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 112 of the 122 other email apps grade higher. Open-Xchange is open source, so there is a third way: take its code and run it yourself.
What you could make
- Calendar: an app builder makes this well.
What you could not
- An email client: sending, receiving, threading and searching years of mail.
- AI features, unless you pay a model provider for each request yourself.
- Sharing with other people, which means accounts and invitations.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Open-Xchange’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
