Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
1.8
GPA, above 2 of the 122 other email apps we grade
Open-Xchange makes OX App Suite, an open-source email, calendar and collaboration platform sold to telecom operators, hosting providers and public-sector organizations. It runs on-premise, in a public cloud or as the managed OX Cloud service, and includes documents, drive storage, tasks and an AI agent. Pricing is not published.
To get you started, here are 7 things to know about Open-Xchange, taken from its own pages and our grades.
It publishes no prices and doesn't sell to individuals.
- 1

- 4
Documents, drive and tasks
Text documents, spreadsheets and presentations in the browser, cloud storage tied to email, and personal and shared tasks.

The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | No prices are published, so there is nothing to compare. The site sends buyers to a demo. |
| Free plan and trial | F | Nothing free is listed. Buyers book a demo or contact sales. |
| Features | B | Email, calendar, documents, drive, tasks, encryption and an AI agent, all in one suite, with nothing missing from the mail and calendar job. |
| Ease of use | C | No store rating on record. A provider sets it up for you, and what you get depends on who that is. |
| Platforms and integrations | C | Web only on record, with Dovecot Pro, PowerDNS and openDesk as connections. No apps of its own listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- Telcos, ISPs and hosting companies offering branded email to customers
- Governments and public-sector bodies that want sovereign, open-source email
- Organizations replacing Gmail or Outlook at large scale
Worth knowing
- No prices are published; the site directs buyers to book a demo or contact sales.
- The site markets to service providers and the public sector, not individuals or small teams.
- The public-sector page says it is most commonly deployed on-premise.
- OX App Suite is described as open source, but Dovecot Pro, a related product, is a commercial edition.
Part 02 · Pricing
What it costs
Every plan, the free plan, ways to pay less and how prices have moved
Open-Xchange's current pricing could not be confirmed from its own site.
No prices are published, so there is nothing to compare.
We could not confirm Open-Xchange’s current prices from its own site, so this guide lists no plans. ox.io has them.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
2/122
Other email apps it is graded above
Open-Xchange's GPA of 1.8 is higher than 2 of the 122 other email apps we grade, and level with 8.
It stands best on features (B, above 79 of 122) and worst on free plan and trial (F, above 0).
Each grade against the category
Every bar is all 123 email apps we grade, cut by the letter each got. Open-Xchange’s own letter is outlined.
- CValue for moneyAbove 13 of 122
- FFree plan and trialAbove 0 of 122
- BFeaturesAbove 79 of 122
- CEase of useAbove 20 of 122
- CPlatforms and integrationsAbove 10 of 122
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
