The short version

  • Only Soketi has a free tier, so it costs nothing to try first.
  • Each has a real cost: Soketi maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.; 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: Soketi covers Pusher protocol compatibility, ThetaRay covers Unsupervised detection.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Soketi

  • A Laravel application that already uses Echo and wants to stop paying a hosted realtime providernot ThetaRay
  • Realtime notifications or presence indicators where data must not leave your own infrastructure for compliance reasonsnot ThetaRay
  • A local or CI environment that needs a Pusher-compatible server without hitting a paid accountnot ThetaRay
  • A high-connection-count application where hosted per-connection pricing has become the largest line in the infrastructure billnot ThetaRay

ThetaRay

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

Where each one falls short

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

Soketi

  • Maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
  • Dependency drift on Node and uWebSockets.js will eventually force you to fork or migrate, and that cost is unbudgeted at the point you adopt it.
  • There is no commercial support to buy, so a production incident at three in the morning is entirely your problem with no escalation path.
  • Scaling beyond a single node needs Redis and careful configuration, and getting presence channels correct across nodes is a genuine source of subtle bugs.
  • It implements the Pusher protocol rather than tracking it, so any protocol feature Pusher adds later will not appear, and the compatibility guarantee slowly decays.

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

Soketi: Is Soketi still maintained?

Barely. The maintainer has stated that available time is very limited and releases have been sparse; treat it as community-maintained.

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.

Soketi: Do I need to change my client code?

No. Pusher client SDKs and Laravel Echo work by changing the host, port and credentials.

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.

Soketi: What does it cost?

Nothing in licence fees. It is MIT licensed; you pay for the server it runs on.

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.

Soketi: What are people moving to?

Laravel Reverb for Laravel applications, and Sockudo, a Rust reimplementation, for others.
