The short version

  • Only PartyKit has a free tier, so it costs nothing to try first.
  • Each has a real cost: PartyKit documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.; Socure coverage and accuracy depend on US consumer data density, so international expansion means adding a second, document-based vendor rather than scaling the same contract.
  • They diverge on capability: PartyKit covers Stateful edge servers, Socure covers ID+ identity verification.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

PartyKit

  • Documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • Commercial free tier requires deploying to the user's own Cloudflare account, adding setup complexity.
  • Storage on the free Individual plan clears every 24 hours, limiting it to prototyping rather than persistent production data.
  • Smaller ecosystem and community than more established realtime infrastructure providers.

Socure

  • Coverage and accuracy depend on US consumer data density, so international expansion means adding a second, document-based vendor rather than scaling the same contract.
  • Data-only verification performs worst on thin-file populations, and young, recently arrived or credit-invisible applicants are declined at higher rates, which creates a fair lending exposure a bank must monitor.
  • Pricing is per decision with an annual commitment and is not published, so the cost of a traffic spike or a bot attack on your signup flow lands on your bill.
  • Modules for verification, fraud and compliance are licensed separately, so the shortlist price rarely matches the final contract once screening and document fallback are added.
  • A probabilistic score is harder to defend to an examiner than a documented identification procedure, so US institutions still have to map the score to explicit Customer Identification Programme controls themselves.

Answered from the vendors’ own pages

PartyKit: How much does PartyKit cost?

PartyKit is completely free. Both the Individual and Commercial plans have no upfront costs.

Source
Socure: Does Socure work outside the United States?

International coverage exists but the data depth that makes the US product accurate is not replicated everywhere. Most global buyers pair it with a document vendor.

PartyKit: What is PartyKit's Individual plan?

The Individual plan is free and includes deployment to a global edge platform, support for up to 10 live projects, and is suitable for small projects. Storage is cleared every 24 hours.

Source
Socure: Can it verify without a document photo?

Yes, that is the core proposition. Document verification is available as a step-up when the data-only score is inconclusive.

PartyKit: What is PartyKit's Commercial plan?

The Commercial plan is free but requires deploying to your own Cloudflare account. It includes custom domains, unlimited projects, and you pay only your Cloudflare usage costs.

Source
Socure: Is pricing published?

No. It is quoted per decision against an annual volume commitment.

PartyKit: Can I upgrade from Individual to Commercial plan?

Yes, both plans are free but offer different feature sets. The Commercial plan removes project restrictions but requires managing your own Cloudflare infrastructure.
