The short version

  • Only Nextcloud has a free tier, so it costs nothing to try first.
  • Each has a real cost: Nextcloud requires self-hosted deployment on organisation-controlled infrastructure; no managed cloud option provided by Nextcloud; VAST Data data reduction ratios drive the economics, and datasets that are already compressed, such as media or encrypted files, reduce poorly and destroy the cost per terabyte case.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nextcloud

  • Requires self-hosted deployment on organisation-controlled infrastructure; no managed cloud option provided by Nextcloud
  • Operational overhead: organisations must apply security patches, manage backups, configure SSL certificates, and handle system administration
  • Scalability challenges at very large user counts (10,000+); requires careful database and storage tuning
  • Mobile clients lack some features of web interface (scripting, advanced admin functions); feature parity varies across platforms
  • Integration with Microsoft 365 and Google Workspace is limited; Nextcloud does not replace Exchange or Gmail directly

VAST Data

  • Data reduction ratios drive the economics, and datasets that are already compressed, such as media or encrypted files, reduce poorly and destroy the cost per terabyte case.
  • There is a minimum viable cluster size, so the entry cost is high and the platform is not sensible for a small footprint however attractive the architecture is.
  • Pricing is quoted against effective capacity after reduction, which means the price you signed depends on an assumption about your own data that only becomes measurable after deployment.
  • The platform has expanded into database and data catalogue functions, which broadens the roadmap but means buyers evaluating it as a file system must be careful not to be sold an adjacent product they will not use.
  • As a relatively young vendor in a market of long-lived incumbents, buyers with ten year retention requirements should press on long term support commitments and hardware availability rather than assume them.

Answered from the vendors’ own pages

Nextcloud: Is Nextcloud Community Edition free to use?

Yes. Nextcloud Community Edition is completely free and open-source under the AGPL-3.0 licence. There are no licensing fees, but organisations must host and maintain their own servers.

Source
VAST Data: Do we still need an archive tier?

That is the central claim, and it holds when your data reduces well. Run a reduction assessment on your actual dataset before accepting the economics.

Nextcloud: Can I migrate from Dropbox or Google Drive to Nextcloud?

Yes. Nextcloud provides migration tools and documentation for importing files from competing platforms. Professional services are available through Nextcloud Enterprise for large-scale migrations.

Source
VAST Data: How is capacity priced?

On usable capacity after data reduction, quoted rather than published. That makes the reduction ratio assumption the most important number in the contract.

Nextcloud: What video conferencing capabilities does Nextcloud Talk provide?

Nextcloud Talk provides end-to-end encrypted audio and video calls, group conferencing, screen sharing, call recording with transcription, live translation, and integration with external services (Slack, Teams, Matrix). Recordings are stored locally on the Nextcloud server.

Source
VAST Data: Is it suitable for a small deployment?

No. There is a minimum cluster size and the entry cost reflects it. Small footprints are better served elsewhere.
