The short version

  • Each has a real cost: Sweep limited to JetBrains IDEs only, not available for VS Code or other editors; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: Sweep covers Autocomplete, Thanos covers Global query.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

Sweep

  • Limited to JetBrains IDEs only, not available for VS Code or other editors
  • Free tier limited to 1,000 autocompletes per month
  • API credit consumption varies by feature usage
  • Performance dependent on codebase size and indexing quality

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

Answered from the vendors’ own pages

Sweep: What programming languages does Sweep support?

Sweep works with all programming languages supported by JetBrains IDEs, including Python, Java, JavaScript, Go, Kotlin, C++, and many others.

Source
Thanos: Is Thanos free?

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

Sweep: Does Sweep retain my code data?

No. Sweep is SOC 2 Type II certified with zero data retention. Code is processed for suggestions but not stored.

Source
Thanos: Does Thanos replace Prometheus?

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

Sweep: Can I cancel my Sweep subscription anytime?

Yes. You can cancel your subscription at any time from your account settings with no long-term commitments or cancellation fees.

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.
