The short version

Only Moonrepo has a free tier, so it costs nothing to try first.
Each has a real cost: Moonrepo smaller community compared to established build systems like Bazel; 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: Moonrepo covers Task orchestration, Zeta covers Tachyon card processing.

Where each one falls short

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

Moonrepo

Smaller community compared to established build systems like Bazel
Limited integrations with enterprise CI/CD platforms
Documentation gaps in some advanced use cases
No commercial support option for organizations requiring guaranteed SLAs

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.
