The short version
- Only Tilt has a free tier, so it costs nothing to try first.
- Each has a real cost: Tilt docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform.; 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: Tilt covers Live update, Zeta covers Tachyon card processing.
- Prices and features above were last checked on 1 September 2026.
Where they differ
Only the attributes on which Tilt and Zeta actually diverge.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Tilt
- Docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform.
- The Tiltfile is Starlark, a Python dialect, so non-trivial setups become real programs that need reviewing and maintaining, and the person who wrote yours becomes a single point of failure.
- Live update only works when the running container can accept synced files and restart the process; compiled languages, distroless images and read-only filesystems often force you back to a full image rebuild, which removes the main benefit.
- It assumes Kubernetes. If your development target is plain Docker Compose or serverless functions, Tilt adds a cluster you did not need and a layer of abstraction with no payoff.
- There is no commercial support contract, no SLA and no paid tier, so when a Kubernetes version upgrade breaks something you are dependent on GitHub issues and a Slack channel rather than a vendor you can escalate to.
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 Tilt or Zeta better?
- Neither clearly leads. Tilt 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, Tilt or Zeta?
- Tilt has a free tier; the other does not. Paid plans start at Free for Tilt and On request for Zeta.
- Does Tilt or Zeta run on more platforms?
- Tilt runs on Linux, macOS, Windows. Zeta runs on Web, API, Cloud, iOS, Android.
- Can I use Tilt for free?
- Yes. Tilt has a free tier, so you can try it without paying. Zeta starts at On request.
- What is Tilt best used for?
- Tilt is most often used for a team of ten or more engineers whose application is fifteen microservices on kubernetes and who currently wait on ci to test a change, an organisation onboarding new developers who want a single command that stands up the whole stack from a committed tiltfile, a platform team giving product engineers a consistent local environment against a shared remote development cluster, a codebase where one repository contains several services and rebuilding all of them on every edit is the main source of lost time. Of those, a team of ten or more engineers whose application is fifteen microservices on kubernetes and who currently wait on ci to test a change and an organisation onboarding new developers who want a single command that stands up the whole stack from a committed tiltfile are not what Zeta is typically brought in for.
- What can Tilt do that Zeta cannot?
- Tilt covers Live update, Tiltfile as code, Unified web UI, Selective rebuilds. Zeta covers Tachyon card processing, Real time authorisation, Rewards and offers engine, Core banking modules.
Answered from the vendors’ own pages
Tilt: Is Tilt free?
Yes, entirely. It is Apache 2.0 open source with no paid tier and no licence fee.
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.
Tilt: Who owns Tilt now?
Docker, which acquired it in May 2022. It remains open source and the repository is still actively maintained.
Zeta: What is its strongest use case?
United States credit card issuing and processing, where legacy platforms make product changes slow and expensive.
Tilt: Do I need a remote cluster?
No. It works against a local cluster such as kind, minikube or Docker Desktop, and also against a shared remote development cluster if your services are too heavy to run locally.
Zeta: Does Zeta provide the BIN or licence?
No. It processes. Network membership, BIN sponsorship and regulatory obligations stay with the issuer.
Tilt: How is it different from Skaffold?
Both automate the build-deploy loop. Tilt puts more weight on the live-update path and a multi-service dashboard; Skaffold is more configuration-driven and closer to Google's tooling.
