The short version

  • Only Refact has a free tier, so it costs nothing to try first.
  • Each has a real cost: Refact requires configuration for optimal performance; 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: Refact covers Autonomous agent workflows, ThetaRay covers Unsupervised detection.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

Refact

  • Autonomous code generation for development tasksnot ThetaRay
  • End-to-end bug fixes and refactoringnot ThetaRay
  • Multi-language software development accelerationnot ThetaRay
  • Enterprise development with data privacy requirementsnot ThetaRay

ThetaRay

  • A correspondent bank that cannot see the ultimate originator and needs behavioural signals rather than counterparty listsnot Refact
  • A cross-border payments fintech whose rules engine produces more alerts than its compliance team can clearnot Refact
  • A bank under a regulatory consent order needing demonstrable improvement in detection within a fixed periodnot Refact
  • A payment institution entering a high-risk corridor where existing thresholds were calibrated on domestic trafficnot Refact

Where each one falls short

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

Refact

  • Requires configuration for optimal performance
  • On-premise deployment adds operational complexity
  • Free tier limited by daily agent request quota
  • Coin system adds complexity to cost calculation

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.
