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.; Trend Micro Vision One licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • They diverge on capability: PartyKit covers Stateful edge servers, Trend Micro Vision One covers Cross-layer correlation.
  • Prices and features above were last checked on 30 August 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.

Trend Micro Vision One

  • Licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • Retention in the XDR data lake beyond the included window is bought with additional credits, so the retrospective hunting the platform is sold on is precisely the part with an ongoing meter attached, and teams shorten retention to control spend.
  • The correlation that justifies the platform only exists over deployed Trend sensors, so an organisation running only the endpoint agent gets an EDR with a large console, and reaching the advertised value means a de facto single-vendor commitment across email, network and workload.
  • Legacy management planes persist: Apex Central, Deep Security Manager and the older Cloud One consoles overlap with Vision One and migrations have run for years, so administrators frequently maintain two consoles for the same agents and learn both.
  • The agents hook file and network operations, so on build servers, database hosts and developer machines the overhead is noticeable, and the standard remedy is broad path exclusions that remove protection from exactly the directories where attackers stage tooling.

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
Trend Micro Vision One: What are Trend Micro Credits?

A single purchased pool of licensing units drawn down by whichever Vision One modules you activate, at different rates per module and per protected object. It replaces separate per-product subscriptions and shifts the forecasting problem onto you.

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
Trend Micro Vision One: Is this the same thing as Deep Security?

Not the same, but related. Server and workload protection in Vision One descends from Deep Security, and Trend has been migrating Deep Security and Cloud One Workload Security customers onto the Vision One platform. Existing Deep Security deployments still exist in the field.

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
Trend Micro Vision One: Does it replace my SIEM?

No. It correlates and retains telemetry from Trend sensors and selected third parties, but it is not a general-purpose log store for every system in the estate, and compliance log retention requirements are usually still met elsewhere.

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.

Source
Trend Micro Vision One: Do I have to use Trend endpoint protection?

To get real value, effectively yes. Third-party ingestion exists but the correlation quality depends on Trend's own sensor telemetry, and a Vision One deployment over someone else's endpoint agent is not what the platform is designed around.

Trend Micro Vision One: Where is the data held?

In the regional instance you choose at onboarding. Confirm the specific region against your residency obligations before deployment, because moving afterwards is a migration.
