The short version

  • Only PartyKit has a free tier, so it costs nothing to try first.
  • Each has a real cost: IDnow agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.; PartyKit documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • They diverge on capability: IDnow covers VideoIdent, PartyKit covers Stateful edge servers.
  • 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.

IDnow

  • Agent-led video identification costs several times an automated check and depends on agent availability, so peak-time queues push abandonment up at exactly the moment conversion matters.
  • Pricing is quoted with an annual volume commitment, so the accreditation advantage comes with a floor you pay whether or not you use it.
  • The product is optimised for European regulatory regimes, so buyers verifying users in North America, Asia or Africa will find coverage and cost less competitive than global specialists.
  • Qualified electronic signature is a separate licence from identity verification, which surprises buyers who assumed the accredited identity check made the signature capability included.
  • Integration for the regulated flows is heavier than a simple SDK drop-in because the compliant journey, including consent and recording requirements, constrains the user experience you can build.

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.

Answered from the vendors’ own pages

IDnow: Why choose it over a cheaper automated vendor?

Because in some European regimes the cheaper vendor is not legally permitted for the transaction. This is an eligibility question, not a quality one.

PartyKit: How much does PartyKit cost?

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

Source
IDnow: Is the electronic signature included?

No. Qualified electronic signature under eIDAS is licensed separately from identity verification.

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
IDnow: Where is the data processed?

In European data centres, which is a requirement rather than a preference for many of its regulated customers.

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
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.
