What is Open Archiver?

Open Archiver is a self-hosted email archive for archiving, storing, indexing and searching email from IMAP servers, Google Workspace, Microsoft 365 and PST, EML and mbox files. Upstream describes it as free from vendor lock-in. A self-hosted Open Archiver is an alternative to a hosted email archiving service, with the open-source build released under AGPL-3.0, and it stores each message as an .eml file with its attachments.

On xCloud it is Open Archiver v0.6.0 with PostgreSQL 17, Valkey 8 and Meilisearch 1.38 as private services, all pinned by digest, on four persistent volumes. xCloud generates the secrets and serves the web interface over HTTPS. Retention policies, legal holds, the audit-log UI and SMTP journaling are in the separate enterprise build, which this template does not use.

From Sign-Up to a Live Open Archiver In Just 3 Easy Steps

An email archive needs the app, a database, a queue, a search index, five secrets, a domain and a certificate before the first message is archived. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick Open Archiver from the OneClick catalog. Choose your domain and a server with 2 CPU cores and 4 GB of RAM or more; the install form has no fields.
Step 02
We Deploy It For You
One click. We start Open Archiver v0.6.0 with PostgreSQL 17, Valkey 8 and Meilisearch 1.38 on four volumes, all pinned by digest, generate the secrets and publish it over HTTPS. The first boot takes three to five minutes.
Step 03
Claim The Super Admin
Open your HTTPS URL and complete the setup page right away, because the first visitor becomes Super Admin. Then add an ingestion source such as IMAP, or upload a PST, zipped EML or mbox file. Keep a copy of the encryption key.

Everything Open Archiver Does, On Your Own Server

Open Archiver runs here as the open-source build: ingestion, storage and full-text search on a server you control.

IMAP, Google And Microsoft Ingestion
Connect an IMAP server, Google Workspace or Microsoft 365 for a bulk import and continuing sync. Google and Microsoft sources register an OAuth callback on your domain.
PST, EML And mbox Import
Upload PST files, zipped EML files or mbox files through the browser, up to 100 MB each. Larger mailboxes use the Local Path source with files already in the container.
Full-Text Search With Meilisearch
Search the text of emails and attachments such as PDF and DOCX through a Meilisearch index kept on its own volume.
Integrity Reports
Upstream stores file hashes at ingestion and gives each archived email an integrity report that shows whether the files are original.
Standard .eml Storage
Emails are stored as .eml files with attachments on the open_archiver_data volume, and upstream also supports S3-compatible storage.
Roles, API Keys And MFA
The open-source build provides roles, API keys and multi-factor authentication. Retention policies and the audit-log UI belong to the enterprise build, which this template does not use.

What You Can Do With Open Archiver

Keep a permanent copy of company mail
Archive a mailbox from Google Workspace or Microsoft 365 into storage you control, so a copy outlives the account it came from.
Search old mail and attachments in one place
Find an email or a PDF attachment from years back with full-text search instead of scrolling through exports.
Import a PST or mbox you already hold
Upload a PST, zipped EML or mbox file from a departed employee or an old mail system and make it searchable.
Check that archived mail is unaltered
Open an email's integrity report to see whether the stored files still match the hashes recorded when they were ingested.

Open Archiver vs Alternatives

Hosted email archiving services: As a self-hosted alternative to hosted email archiving, Open Archiver keeps the mail on your own server, which upstream presents as freedom from vendor lock-in.
Piler: In an Open Archiver vs Piler comparison, weigh Open Archiver's AGPL-3.0 licence, its IMAP, Google Workspace, Microsoft 365 and file ingestion, and its four services.
Mailu: Mailu has its own OneClick page. It is a mail server, whereas Open Archiver archives mail that arrives from IMAP, Google Workspace, Microsoft 365 or files.
Paperless-ngx: Paperless-ngx has its own OneClick page. It archives scanned and digital documents, while Open Archiver archives email as .eml files.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

Can you self-host Open Archiver with Docker?

Yes. Upstream installs with Docker Compose, and this template is Open Archiver Docker hosting without the setup: the app, PostgreSQL, Valkey and Meilisearch, all pinned by digest, on four volumes with HTTPS on your own domain.

How much RAM does Open Archiver need?

The manifest asks for 4096 MB of RAM, 2 CPU cores and 20 GB of disk; QA measured about 0.9 GB idle. The indexing worker alone can use a 2 GB heap, and the archive grows with the mail you ingest.

Who becomes the admin in Open Archiver?

The first visitor to open the site creates the Super Admin account on the setup page. Until that happens anyone who finds the domain can claim the instance, so complete the setup page immediately after deploying, before you share the address.

Can Open Archiver archive Gmail or Microsoft 365?

Yes. Upstream ingests Google Workspace and Microsoft 365 as well as IMAP servers. For Google and Microsoft sources, register https://your-domain/api/v1/oauth/callback with the provider, and update that address with the provider if you ever change the domain.

Can I import PST or mbox files into Open Archiver?

Yes. Upload PST, zipped EML or mbox files in the browser, up to 100 MB each, because the proxy caps request bodies there. For larger archives use the Local Path source with files already inside the container.

Is Open Archiver open source?

Yes. The build this template deploys is released under AGPL-3.0, so there is no licence fee. You pay only for the Cloud VPS, which makes this an Open Archiver cloud of your own instead of a vendor-hosted archive.

Does Open Archiver delete emails?

Not by default. Deleting emails and ingestion sources from the interface is off until you enable upstream's ENABLE_DELETION setting. Retention policies and legal holds belong to the enterprise build, which this template does not include.

Who can see the archived email?

Anyone who can sign in can see everything archived, including mail contents, attachments and the credentials of connected mailboxes. There is no public sign-up after the first account, so keep admin logins private and consider Basic Auth at your proxy.

How do I back up Open Archiver?

Back up all four volumes together: open_archiver_data, open_archiver_postgres, open_archiver_valkey and open_archiver_meili. Keep the encryption key too, since stored mailbox credentials cannot be decrypted without it. Nothing backs up automatically, so run the copy yourself and test a restore.

Backup and restore Docker apps

How do I upgrade Open Archiver?

The install stays on its pinned v0.6.0 images until you adopt a newer template version. Back up all four volumes and the keys first and read the upstream release notes, because Meilisearch index data is not compatible across versions.

What happens if I change the encryption key?

The stored credentials of your ingestion sources become unreadable, so treat ENCRYPTION_KEY as permanent after first use. Changing JWT_SECRET only signs everyone out. The key is shown on the credentials page, so keep a copy somewhere safe.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
