The short version

  • Only Pieces for Developers has a free tier, so it costs nothing to try first.
  • Each has a real cost: Pieces for Developers requires installing and running a background desktop app rather than being purely cloud-based.; ThetaRay unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • They diverge on capability: Pieces for Developers covers Activity Timeline, ThetaRay covers Unsupervised detection.
  • 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.

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.

ThetaRay

  • Unsupervised models are harder to justify to an examiner than explicit rules, and some regulators still expect documented threshold logic, which can force you to run both systems.
  • The alert reduction claim depends heavily on your data, so a parallel run is essential and adds months and cost before you can decommission the incumbent.
  • Coverage is strongest in cross-border and correspondent flows; institutions whose risk is domestic retail fraud will find the fit weaker than a general-purpose monitoring platform.
  • It is a smaller vendor than the incumbents, so integration connectors into legacy core banking systems are often bespoke work rather than a supported adapter.
  • Model retraining and tuning are vendor-led, which means changing detection behaviour is a support conversation rather than something your own analysts can do that afternoon.

Answered from the vendors’ own pages

Pieces for Developers: Does Pieces store my data in the cloud?

Pieces stores captured data on-device by default, giving users granular controls to pause, disable or delete captures rather than relying solely on cloud storage.

ThetaRay: Does it replace a rules engine entirely?

Rarely on day one. Most institutions run it alongside existing rules during a parallel period, and some keep specific regulator-mandated rules permanently.

Pieces for Developers: Is there a free plan for Pieces?

Pieces does not offer a permanently free plan; new users instead get a 7-day free trial on any plan, which requires a credit card to start.

Source
ThetaRay: Where is the data processed?

SaaS runs on Microsoft Azure with regional deployment options, which is the mechanism for meeting data residency conditions in regulated markets.

Pro is $18.99 per month billed monthly, with roughly a 25% discount available when billed yearly.

Source
ThetaRay: Is sanctions screening included?
