The short version
- Only Coda has a free tier, so it costs nothing to try first.
- Each has a real cost: Coda mobile apps are significantly weaker than competitors with sign-in issues and poor performance; 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: Coda covers Interactive documents, 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.
Coda
- Mobile apps are significantly weaker than competitors with sign-in issues and poor performance
- No offline mode limits accessibility
- Limited direct import and export options, no native Markdown or workspace-level Word export
- Requires significant time investment to master compared to simpler alternatives
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.
