The short version

  • Each has a real cost: SolidJS much smaller ecosystem than React, so many problems have no off-the-shelf library; Thanos several components — sidecar, store, querier, compactor, ruler — each with its own configuration and failure modes
  • They diverge on capability: SolidJS covers No virtual DOM, Thanos covers Global query.
  • Prices and features above were last checked on 29 August 2026.

What each one covers

Drawn from each product's published feature list. An absence here means we hold no record of it - not that the product lacks it.

Only in SolidJS

  • No virtual DOM
  • Components run once
  • JSX syntax
  • Small bundles

Only in Thanos

  • Global query
  • Object storage retention
  • Deduplication
  • Downsampling

What people use each for

The jobs each tool is most often brought in to do.

SolidJS

  • Interfaces where update performance is the binding constraintnot Thanos
  • Teams comfortable with React syntax who want finer-grained reactivitynot Thanos
  • Applications where bundle size directly affects the businessnot Thanos

Thanos

  • Querying metrics across many clusters or regions from one placenot SolidJS
  • Retaining metrics for years without local disk growthnot SolidJS
  • Removing the gap that appears when a single Prometheus instance restartsnot SolidJS

Where each one falls short

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

SolidJS

  • Much smaller ecosystem than React, so many problems have no off-the-shelf library
  • The React-like syntax is misleading: components run once, and React habits produce subtle bugs
  • Smaller hiring pool and fewer learning resources than the mainstream frameworks

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

Questions people ask

Is SolidJS or Thanos better?
Neither clearly leads. SolidJS starts at Free and Thanos at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, SolidJS or Thanos?
SolidJS starts at Free and Thanos at Free.
Does SolidJS or Thanos run on more platforms?
SolidJS runs on Web. Thanos runs on Kubernetes, Linux, Docker.
Can I use SolidJS for free?
Both have a free tier, so you can try either at no cost before committing.
What is SolidJS best used for?
SolidJS is most often used for interfaces where update performance is the binding constraint, teams comfortable with react syntax who want finer-grained reactivity, applications where bundle size directly affects the business. Of those, interfaces where update performance is the binding constraint and teams comfortable with react syntax who want finer-grained reactivity are not what Thanos is typically brought in for.
What can SolidJS do that Thanos cannot?
SolidJS covers No virtual DOM, Components run once, JSX syntax, Small bundles. Thanos covers Global query, Object storage retention, Deduplication, Downsampling.

Answered from the vendors’ own pages

SolidJS: Is SolidJS free?

Yes, open source under the MIT licence.

Thanos: Is Thanos free?

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

SolidJS: Is SolidJS just React without the virtual DOM?

The syntax is similar but the model is not. Solid components run once and reactivity is fine-grained, so patterns that are correct in React can be wrong in Solid.

Thanos: Does Thanos replace Prometheus?

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

SolidJS: Why is SolidJS fast?

It compiles away much of the framework and updates individual DOM nodes directly, rather than re-rendering components and diffing a virtual DOM.

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.
