The short version

  • Each has a real cost: Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes; Vagrant vagrant 2.4.3 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • They diverge on capability: Thanos covers Global query, Vagrant covers Box management.

Where each one falls short

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

Thanos

  • Several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • The compactor is a common source of operational trouble and must not run twice against the same bucket
  • Query latency over object storage is meaningfully higher than local Prometheus
  • Object storage costs and API request charges become real at high volume

Vagrant

  • Vagrant 2.4.3 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Vagrant to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vagrant
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published
  • Uses that fall outside the Additional Use Grant require a separately negotiated licence from the licensor

Questions people ask

Is Thanos or Vagrant better?
Neither clearly leads. Thanos starts at Free and Vagrant at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Thanos or Vagrant?
Thanos starts at Free and Vagrant at Free.
Does Thanos or Vagrant run on more platforms?
Thanos runs on Kubernetes, Linux, Docker. Vagrant runs on Linux, Windows, Mac.
Can I use Thanos for free?
Both have a free tier, so you can try either at no cost before committing.
What is Thanos best used for?
Thanos is most often used for querying metrics across many clusters or regions from one place, retaining metrics for years without local disk growth, removing the gap that appears when a single prometheus instance restarts. Of those, querying metrics across many clusters or regions from one place and retaining metrics for years without local disk growth are not what Vagrant is typically brought in for.
What can Thanos do that Vagrant cannot?
Thanos covers Global query, Object storage retention, Deduplication, Downsampling. Vagrant covers Box management, Provider support, Multi-machine setups, Provisioners.

Answered from the vendors’ own pages

Thanos: Is Thanos free?

Yes, open source and CNCF-incubating. Costs are the object storage it uses.

Vagrant: Is Vagrant free to use?

Vagrant is a free, open-source command-line utility for managing virtual machine lifecycles.

Source
Thanos: Does Thanos replace Prometheus?

No. It runs alongside existing Prometheus servers, adding global query, deduplication and long-term storage.

Vagrant: Does Vagrant offer a paid tier?

Vagrant itself is free. HashiCorp offers a HCP Vagrant Registry with a free tier for use with Vagrant.

Source
Thanos: Thanos or VictoriaMetrics?

Thanos layers onto Prometheus using object storage and is the more established multi-cluster answer. VictoriaMetrics is a separate store aiming at lower resource use and fewer moving parts.
