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.; Zeta it competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
- They diverge on capability: Jitsu covers Event collection, Zeta covers Tachyon card processing.
- Prices and features above were last checked on 1 September 2026.

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.
Zeta
- It competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
- Contracts are enterprise scale and quoted with volume minimums, which puts it out of reach of small issuers who would otherwise benefit most from modern tooling.
- A card portfolio migration runs twelve to twenty four months at minimum, during which the issuer runs two platforms and pays for both.
- Zeta is a processor rather than a licence holder, so network membership, BIN sponsorship and regulatory obligations remain entirely with the issuer.
- Public references for large live United States production volumes are fewer than the announcements imply, so diligence should insist on active account counts and uptime history rather than partnership press releases.

Questions people ask
- Is Jitsu or Zeta better?

- Yes. Jitsu has a free tier, so you can try it without paying. Zeta starts at On request.
- What is Jitsu best used for?

Of those, a team paying five figures a year to a customer data platform when all it actually does is send events to snowflake and an engineering group that needs event collection running inside its own vpc for data residency or security review reasons are not what Zeta is typically brought in for.

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.
Zeta: Which Zeta is this?
The banking technology company founded by Bhavin Turakhia, which builds the Tachyon card processing and core banking platform. Not any similarly named payroll or accounting product.
Jitsu: Can I self-host for free?
Yes. The project is MIT licensed with no usage limits when self-hosted.
Zeta: What is its strongest use case?
United States credit card issuing and processing, where legacy platforms make product changes slow and expensive.
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.
Zeta: Does Zeta provide the BIN or licence?
No. It processes. Network membership, BIN sponsorship and regulatory obligations stay with the issuer.
Jitsu: Does Jitsu do identity resolution?
No. It transports and transforms events; identity stitching and audiences are not part of the product.
