The short version

  • Only PartyKit has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fenergo implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.; PartyKit documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • They diverge on capability: Fenergo covers Regulatory rules library, 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.

Fenergo

  • Implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
  • It orchestrates screening but does not supply the sanctions, PEP or adverse media data, so you still buy Dow Jones, LexisNexis or World-Check separately and those fees are per screened entity.
  • The entry price is set for institutions with large onboarding volumes, which puts it out of reach of smaller banks and fintechs that would otherwise benefit from the rules library.
  • Configuration is deep and specific, which makes upgrades between major versions a project rather than a patch, and some customers stay on old releases for years.
  • The rules library covers regulatory requirements, not your internal risk appetite, so the policy tuning that determines whether onboarding actually gets faster remains your work.

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

Fenergo: Does Fenergo do the sanctions screening itself?

No. It orchestrates calls to third-party data providers such as Dow Jones and World-Check, and those subscriptions are additional and usually charged per screened entity.

PartyKit: How much does PartyKit cost?

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

Source
Fenergo: Is it SaaS or on-premises?

Both. The SaaS offering runs on Microsoft Azure with regional deployment options, which matters where data residency rules prohibit client data leaving the jurisdiction.

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
Fenergo: How long does a deployment take?

Plan for a year at minimum for a multi-jurisdiction rollout. Single-jurisdiction deployments with a narrow product set can be shorter but rarely under six months.

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.
