The short version

  • Each has a real cost: Borg Backup linux, macOS and BSD only; Windows is not a supported platform; Infracost usage-based resources such as object storage, serverless functions and data transfer have no cost without monthly usage figures supplied by hand, and the documentation warns plainly that engineers otherwise read them as free.
  • They diverge on capability: Borg Backup covers Content-defined chunking, Infracost covers Pull request cost diffs.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Borg Backup

  • Linux, macOS and BSD only; Windows is not a supported platform
  • Command-line only, with no graphical interface in the project itself
  • Version 2.0 is still in beta, so production use means staying on the 1.4 line
  • Restoring requires the Borg tooling, since archives are a deduplicated chunk store rather than plain files

Infracost

  • Usage-based resources such as object storage, serverless functions and data transfer have no cost without monthly usage figures supplied by hand, and the documentation warns plainly that engineers otherwise read them as free.
  • Splitting production from non-production usage assumptions is not supported in the free usage file, which the docs attribute to a missing project filter, so that separation requires the paid product.
  • The step from 250 to 1,000 dollars a month is large and the Cloud tier includes only ten admin seats, with developer seats charged at a figure that is not published, so the cost for a large organisation cannot be computed from the pricing page.
  • Estimates are list price. Negotiated agreements, committed use discounts and reserved instance economics require SKU-level overrides available only on Enterprise, so the number in the pull request is not the number on the bill.
  • The share of the product covered by the Apache-2.0 licence is shrinking. Checks, automated fixes, policies and agent integrations are all hosted-only, so the permissive licence increasingly protects the estimation engine rather than the product.

Answered from the vendors’ own pages

Borg Backup: What is the cost of BorgBackup?

BorgBackup is completely free and open source under the BSD license with no mandatory costs for the core software.

Source
Infracost: Is the open source version genuinely useful on its own?

Yes, for estimation. It parses your definitions and produces breakdowns and diffs locally. What it does not do is comment on pull requests, enforce policy or report across an organisation, all of which are hosted-only.

Borg Backup: Are there paid services available for BorgBackup?

Yes, optional third-party services are available: BorgBase for specialized Borg repository hosting, Hetzner Storage Box with Borg support, and rsync.net cloud storage integration.

Source
Infracost: Will the estimate match my cloud bill?

No. It is list price. Committed use discounts, enterprise agreements and reserved instances need SKU-level overrides that sit in the Enterprise tier.

Borg Backup: How can I support the BorgBackup project?

BorgBackup accepts voluntary contributions through Open Collective, GitHub Sponsors, Liberapay, and PayPal, though donations are optional.

Source
Infracost: Why do my S3 and Lambda resources show no cost?

Usage-based resources need monthly usage values supplied in a usage file or defined centrally. Without them they estimate at zero, which is the documented behaviour and the most common way the tool misleads.

Infracost: Has the licence ever changed?

No. The command line tool has been Apache 2.0 throughout, with no Business Source or AGPL episode, which is unusual in this category.

Infracost: What is a run?

Not defined on the public pricing page, and the run allowance is what separates the free and Starter tiers, so establish the definition before choosing between them.
