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 pnpm

Nothing recorded that Thanos does not also cover.

Only in Thanos

Where each one falls short

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

pnpm

  • Requires command-line proficiency to use
  • Community-driven support only

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 pnpm or Thanos better?
Neither clearly leads. pnpm 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, pnpm or Thanos?

Can I use pnpm for free?
Both have a free tier, so you can try either at no cost before committing.
What is pnpm best used for?
pnpm is most often used for installing dependencies faster than npm in monorepo workspaces, sharing common dependencies across multiple projects to save disk space, preventing dependency version conflicts in workspace environments, managing workspaces with many interdependent packages. Of those, installing dependencies faster than npm in monorepo workspaces and sharing common dependencies across multiple projects to save disk space are not what Thanos is typically brought in for.
What can pnpm do that Thanos cannot?
Thanos covers Global query, Object storage retention, Deduplication, Downsampling.

Answered from the vendors’ own pages

pnpm: Is pnpm free and open source?

Yes. pnpm is free and open source software developed for Node.js. Version 10 and 11 are currently available.

Source
Thanos: Is Thanos free?

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

pnpm: How does pnpm save disk space?

pnpm uses a content-addressable store with hard linking and symlinks to avoid duplication. All files are saved in a single place on disk and hard-linked to individual projects, dramatically reducing storage requirements compared to npm.

Source
Thanos: Does Thanos replace Prometheus?

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

pnpm: Is pnpm faster than npm?

Yes. pnpm performs installation in three stages: dependency resolution, directory structure calculation, and linking. Packages are fetched and linked as soon as possible, making it significantly faster than npm's sequential approach.

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.

pnpm: Does pnpm support monorepos?

Yes. pnpm has built-in support for monorepositories. You can create a workspace using pnpm-workspace.yaml to unite multiple projects in a single repository.

Source
pnpm: How does pnpm handle node_modules differently than npm?

pnpm uses symlinks to add only direct dependencies to node_modules root, preventing accidental access to undeclared dependencies. This encourages more explicit dependency management compared to npm's flattened node_modules structure.
