The short version
- Only Spacelift has a free tier, so it costs nothing to try first.
- Each has a real cost: Spacelift users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast.; 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: Spacelift covers Multi-tool orchestration, 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.
Spacelift
- Users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast.
- There is no affordable paid entry point. The free tier stops at two users and the next tier is a five-figure commitment with nothing in between.
- Three of the five tiers are quote-only, so a shortlist cannot be costed without entering a sales process with each vendor on it.
- The self-hosted build lags the hosted one, has no public worker pool and lacks the Azure and Google Cloud integrations available in the SaaS product, with OIDC federation offered as the workaround.
- Stacks, Rego policies, Blueprints, Spaces and Spacelift-managed state are proprietary constructs, so leaving means rebuilding the orchestration layer rather than pointing it at a different runner.
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 Spacelift or Zeta better?
- Neither clearly leads. Spacelift starts at Free and Zeta at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Spacelift or Zeta?
- Spacelift has a free tier; the other does not. Paid plans start at Free for Spacelift and On request for Zeta.
- Does Spacelift or Zeta run on more platforms?
- Spacelift runs on Web, Self-hosted, Cloud. Zeta runs on Web, API, Cloud, iOS, Android.
- Can I use Spacelift for free?
- Yes. Spacelift has a free tier, so you can try it without paying. Zeta starts at On request.
- What is Spacelift best used for?
- Spacelift is most often used for platform teams running infrastructure changes through approval gates rather than through application ci, organisations standardising terraform and opentofu across many teams with policy enforcement, estates needing private runners so cloud credentials never leave the network, teams wanting drift detection and reconciliation rather than plan-time checks alone. Of those, platform teams running infrastructure changes through approval gates rather than through application ci and organisations standardising terraform and opentofu across many teams with policy enforcement are not what Zeta is typically brought in for.
- What can Spacelift do that Zeta cannot?
- Spacelift covers Multi-tool orchestration, Policy as code, Private workers, Spaces. Zeta covers Tachyon card processing, Real time authorisation, Rewards and offers engine, Core banking modules.
Answered from the vendors’ own pages
Spacelift: How is Spacelift priced?
By tier and by private worker count rather than per user. Users are unlimited on every paid plan. The published figure on the pricing page carries no period label, and the FAQ describes the tier as an annual subscription, so confirm the period in writing.
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.
Spacelift: Does it support OpenTofu?
Yes, and Spacelift sponsors the OpenTofu project, which is a substantive hedge for anyone avoiding Terraform under the Business Source Licence.
Zeta: What is its strongest use case?
United States credit card issuing and processing, where legacy platforms make product changes slow and expensive.
Spacelift: Is there a self-hosted version?
Yes, described as carrying Enterprise functionality, but it is priced on request and lags the hosted product on cloud integrations.
Zeta: Does Zeta provide the BIN or licence?
No. It processes. Network membership, BIN sponsorship and regulatory obligations stay with the issuer.
Spacelift: Why not just use the CI system we already have?
That is the real comparison. General purpose CI handles state, drift, approval gates and concurrency control for infrastructure poorly, and whether that is worth a five-figure floor depends on how much infrastructure change your organisation actually ships.
Spacelift: What happens to our pipelines if we leave?
They do not port. Rego policies, Blueprints, Spaces and managed state are Spacelift constructs and the orchestration has to be rebuilt elsewhere.
