The short version

  • Each has a real cost: Arnica per-identity pricing ($25-$50/person/year) requires tracking active developers; 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.
  • They diverge on capability: Arnica covers AI SAST, Jitsu covers Event collection.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Arnica

  • Per-identity pricing ($25-$50/person/year) requires tracking active developers
  • Overage identity tracking via 90-day PR activity can be unpredictable
  • Free plan limited to weekly updates, requiring upgrade for real-time scanning
  • Advanced add-ons (Image Scanning, AI SAST, Agentic Rules Enforcer) pricing not published
  • On-premises deployment limited to Enterprise tier

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.

Answered from the vendors’ own pages

Arnica: How are identities defined in Arnica pricing?

Identities are any users and other contributing entities that contributed code and/or had PR activity during the last 90 days. This ensures billing matches active developers.

Source
Jitsu: Is Jitsu the same as Jitsi?

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

Arnica: What is the annual discount?

Annual prepayment offers approximately 17% savings versus monthly billing. Core Business annual is $300/identity versus $360 for monthly.

Source
Jitsu: Can I self-host for free?

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

Arnica: Can I cancel or downgrade Arnica anytime?

Yes. Subscriptions can be cancelled or downgraded at any time. Overage identities receive automatic protection with true-up invoicing.

Source
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.

Jitsu: Does Jitsu do identity resolution?

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