The short version
- Only Deno has a free tier, so it costs nothing to try first.
- Each has a real cost: Deno egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications; 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.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Deno
- Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
- CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
- Enterprise pricing is not disclosed; requires sales contact
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.
