The short version

  • Only Buildkite has a free tier, so it costs nothing to try first.
  • Each has a real cost: Buildkite free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention; 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.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

  • Deployment automationnot ThetaRay

ThetaRay

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

Where each one falls short

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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac

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

Buildkite: Can I use Buildkite without paying?

Yes, Buildkite offers a free plan that includes up to 5 users, 10 concurrent jobs, 2000 Linux vCPU minutes monthly, and 250k test executions per month at no cost.

Source
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.

Buildkite: What happens if I exceed my included compute minutes on Buildkite?

Hosted agent compute is charged separately at $0.004 per Linux vCPU minute and $0.02 per Mac vCPU minute, billed to the second with no minimums.

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.

Buildkite: Do I need an annual commitment for Buildkite's Pro plan?

No, Buildkite's Pro plan is billed monthly at $30 per active user with no long-term contract required. All tiers include a 30-day all-access trial.

Source
ThetaRay: Is sanctions screening included?

Screening is available on the same platform but licensed as part of the commercial package rather than bundled by default. Confirm it is in your quote.

Buildkite: What user limits apply to each Buildkite plan?
