## Pricing

Open-Xchange's current pricing could not be confirmed from its own site.


## Key features

- **Email and calendar:** A browser interface for email and calendar that the vendor says works the same on desktop, tablet and mobile.
- **Documents, drive and tasks:** Text documents, spreadsheets and presentations in the browser, cloud storage tied to email, and personal and shared tasks.
- **AI agent:** An integrated agent can write emails, schedule appointments, and search, summarize and organize messages, contacts and files.
- **White-label for providers:** Service providers can brand the platform, bundle features and sell tiers, add-ons and upgrades to their own customers.
- **Deployment choices:** Install on-premise, in a public cloud, or use the managed OX Cloud service.
- **OX Guard encryption:** OX Guard provides encrypted email for sensitive communication, which the vendor pitches to regulated professions.

## 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.

## ToolGPA grades

**GPA: 1.8 out of 4**, graded Nov 13, 2026. 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.

- **Value for money: C.** No prices are published, so there is nothing to compare. The site sends buyers to a demo.

- **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.

## Keep it, 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.

- You could make: Calendar: an app builder makes this well.
- You could not: An email client: sending, receiving, threading and searching years of mail.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: Sharing with other people, which means accounts and invitations.
- You could not: The depth: we grade its features B, which means it covers the whole job.
