The short version

  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; LibreOffice real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question
  • They diverge on capability: Chainguard covers Hardened container images, LibreOffice covers Full suite.

Where each one falls short

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

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

LibreOffice

  • Real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question
  • Mobile support is weak, which is disqualifying for a workforce that reviews documents on phones
  • Complex Microsoft Office documents still lose formatting in transit, so exchange-heavy workflows need testing with real files
  • Central policy management, conditional access and audit tooling are thin against the commercial suites
  • Advanced spreadsheet work is where the gap with Excel is widest, and it affects exactly the users least willing to change

Answered from the vendors’ own pages

Chainguard: How much is the Chainguard Containers Catalog?

The Containers Catalog is 19,000 USD per year for 10-person engineering teams, providing access to 2,000+ hardened container images.

Source
LibreOffice: Is LibreOffice really free for business use?

Yes. It is open source with no per-seat licence and no restriction on commercial use. The Document Foundation is funded by donations and sponsors.

Chainguard: What SLAs does Chainguard offer?

Chainguard provides contractual CVE remediation SLAs: 7 days for critical vulnerabilities, 14 days for high/medium/low severity, all with priority support.

Source
LibreOffice: Does it have AI features?

No. The 26.8 release states it contains no generative AI, that documents are not transmitted to remote services, and that no component requires network access.

Chainguard: Can I try Chainguard before purchasing?

Yes. The free tier includes five container images for testing and deployment, allowing hands-on evaluation.

Source
LibreOffice: Can it open Microsoft Office files?

Yes, and save back to them. Round-tripping complex documents is imperfect between any two suites, so test with your own files before committing to an exchange-heavy workflow.

LibreOffice: Why do governments use it?

Two reasons: no per-seat cost at scale, and OpenDocument is an ISO standard implemented by more than one vendor, which matters for archives that must stay readable after a vendor relationship ends.

LibreOffice: What is the biggest reason not to use it?

Collaborative editing. If several people work on the same document simultaneously, Microsoft 365 and Google Workspace are substantially better and that gap is not closing.
