The short version

  • Only Jitsu has a free tier, so it costs nothing to try first.
  • Each has a real cost: Jitsu jitsu is a pipeline, not a customer data platform, so identity resolution, audience building and reverse ETL are absent and a marketing team expecting Segment parity will be disappointed.; Silent Eight automated disposition has to clear model risk governance and a regulator, and the shadow running period before auto-close is permitted can consume most of the first year of the contract.
  • They diverge on capability: Jitsu covers Event collection, Silent Eight covers Alert adjudication.
  • 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.

Jitsu

  • An engineering group that needs event collection running inside its own VPC for data residency or security review reasonsnot Silent Eight
  • A product analytics setup that wants raw events in the warehouse as the source of truth rather than trapped in a vendor toolnot Silent Eight
  • A startup that needs first-party event collection on its own domain to reduce loss from tracker blocking without paying CDP pricesnot Silent Eight

Silent Eight

  • A bank whose level one screening team spends most of its time closing obvious false name matchesnot Jitsu
  • A payments institution with alert volumes growing faster than it can recruit and train analystsnot Jitsu
  • A compliance function asked by a regulator to demonstrate consistency of alert decisions across offshore teamsnot Jitsu
  • An institution that has just tightened screening thresholds after an enforcement action and cannot staff the resulting alert increasenot Jitsu

Where each one falls short

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

Jitsu

  • Jitsu is a pipeline, not a customer data platform, so identity resolution, audience building and reverse ETL are absent and a marketing team expecting Segment parity will be disappointed.
  • Connector sync frequency is deliberately tiered, with the free plan limited to manual runs and one daily sync, so anything approaching operational freshness requires the paid plan or self-hosting.
  • Self-hosting means you own the reliability of a system that drops data silently when misconfigured, and event loss is uniquely hard to notice because nothing errors, the numbers are just quietly lower.
  • The connector catalogue is far smaller than Fivetran or Airbyte, so if your requirement is pulling from many SaaS sources rather than pushing events, Jitsu is the wrong half of the problem.
  • It is a small company with a small commercial team, so enterprise procurement processes around security review, contractual SLAs and support escalation take longer than with an incumbent vendor.

Silent Eight

  • Automated disposition has to clear model risk governance and a regulator, and the shadow running period before auto-close is permitted can consume most of the first year of the contract.
  • It does not improve detection, so an institution with a poorly tuned monitoring system automates the handling of bad alerts rather than fixing why they exist.
  • Pricing is tied to alert volume, which means efficiency gains elsewhere that reduce alerts also reduce the vendor bill in a way sales teams structure minimums against.
  • The headcount saving is only realised if the institution actually reduces the analyst pool, and many banks redeploy rather than cut, leaving the business case unrealised on paper.
  • As a mid-sized private vendor serving tier one banks, concentration risk cuts both ways; the loss of one large client materially affects the company, and buyers should ask about financial stability during diligence.

Answered from the vendors’ own pages

Jitsu: Is Jitsu the same as Jitsi?

No. Jitsu is an open source event data pipeline. Jitsi is an unrelated video conferencing project.

Silent Eight: Does Silent Eight replace our screening system?

No. It consumes alerts from your existing screening and monitoring systems and decides them. The detection layer stays where it is.

Jitsu: Can I self-host for free?

Yes. The project is MIT licensed with no usage limits when self-hosted.

Silent Eight: Will a regulator accept AI closing alerts?

It depends on your jurisdiction and your model governance evidence. Banks typically run extended shadow mode first and phase auto-closure by alert type.

Jitsu: How does the cost compare with Segment?

The Business plan is 99 US dollars a month for two million active events, where a per-tracked-user CDP typically costs orders of magnitude more at comparable volume.

Silent Eight: Where is the company based?

Singapore, with offices in New York, London and Warsaw.

Jitsu: Does Jitsu do identity resolution?

No. It transports and transforms events; identity stitching and audiences are not part of the product.
