The short version

  • Each has a real cost: Buildah linux only, with no native macOS or Windows support; Soketi maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
  • They diverge on capability: Buildah covers Daemonless builds, Soketi covers Pusher protocol compatibility.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Buildah

  • Building images in CI without a privileged Docker daemonnot Soketi
  • Producing minimal images with tighter layer control than a Dockerfile givesnot Soketi
  • Scripted image assembly where a Dockerfile is the wrong abstractionnot Soketi

Soketi

  • A Laravel application that already uses Echo and wants to stop paying a hosted realtime providernot Buildah
  • Realtime notifications or presence indicators where data must not leave your own infrastructure for compliance reasonsnot Buildah
  • A local or CI environment that needs a Pusher-compatible server without hitting a paid accountnot Buildah
  • A high-connection-count application where hosted per-connection pricing has become the largest line in the infrastructure billnot Buildah

Where each one falls short

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

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

Soketi

  • Maintenance has effectively stalled: the maintainer has said time is severely limited, releases are infrequent, and the community has been discussing whether the project is abandoned, which means security fixes may not arrive.
  • Dependency drift on Node and uWebSockets.js will eventually force you to fork or migrate, and that cost is unbudgeted at the point you adopt it.
  • There is no commercial support to buy, so a production incident at three in the morning is entirely your problem with no escalation path.
  • Scaling beyond a single node needs Redis and careful configuration, and getting presence channels correct across nodes is a genuine source of subtle bugs.
  • It implements the Pusher protocol rather than tracking it, so any protocol feature Pusher adds later will not appear, and the compatibility guarantee slowly decays.

Answered from the vendors’ own pages

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Soketi: Is Soketi still maintained?

Barely. The maintainer has stated that available time is very limited and releases have been sparse; treat it as community-maintained.

Buildah: Do I still need a Dockerfile?

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.

Soketi: Do I need to change my client code?

No. Pusher client SDKs and Laravel Echo work by changing the host, port and credentials.

Buildah: How is Buildah different from Podman?

Buildah builds images; Podman runs them. Podman actually embeds Buildah for its build command, and the two are designed to be used together.

Soketi: What does it cost?

Nothing in licence fees. It is MIT licensed; you pay for the server it runs on.

Soketi: What are people moving to?

Laravel Reverb for Laravel applications, and Sockudo, a Rust reimplementation, for others.
