The short version
- Each has a real cost: Nixpacks the project is in maintenance mode with no commits on the default branch since May 2026 and no release since October 2025, so support for new language versions arrives only if someone forks it.; 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: Nixpacks covers Automatic language detection, Soketi covers Pusher protocol compatibility.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Nixpacks and Soketi actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated), category (Developer Tools).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Nixpacks
- The project is in maintenance mode with no commits on the default branch since May 2026 and no release since October 2025, so support for new language versions arrives only if someone forks it.
- Build determinism is softer than it appears, because providers pin a nixpkgs archive commit and bumping that archive silently moves compiler and runtime versions underneath a build that looks unchanged.
- Caching is limited to Docker layers rather than a content addressed graph, so a small change early in the build invalidates everything after it, which is exactly the limitation Railpack was rewritten to fix.
- Images carry Nix store layers and come out larger than an equivalent tuned Dockerfile or buildpack output, which costs registry storage and slows cold pulls on scale-out.
- There is no specification, no vendor neutral governance and no third party provider ecosystem, so a single company was able to redirect strategy and leave every downstream user with a frozen build tool.
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.

Questions people ask
- Is Nixpacks or Soketi better?
- Neither clearly leads. Nixpacks starts at Free and Soketi at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Nixpacks or Soketi?
- Nixpacks starts at Free and Soketi at Free.
- Does Nixpacks or Soketi run on more platforms?
- Nixpacks runs on Linux, macOS, CLI, Docker. Soketi runs on Linux, macOS, Windows.
- Can I use Nixpacks for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Nixpacks best used for?
- Nixpacks is most often used for understanding the build behaviour of a platform that adopted nixpacks before it was frozen, producing container images from a polyglot monorepo where nobody wants to own several dockerfiles, reproducing an existing railway build locally while planning a migration to railpack, comparing what a nix based builder does differently from a buildpack before choosing a successor. Of those, understanding the build behaviour of a platform that adopted nixpacks before it was frozen and producing container images from a polyglot monorepo where nobody wants to own several dockerfiles are not what Soketi is typically brought in for.
- What can Nixpacks do that Soketi cannot?
- Nixpacks covers Automatic language detection, No Dockerfile required, Nix toolchains, Configuration escape hatches. Soketi covers Pusher protocol compatibility, Presence and private channels, Horizontal scaling, App management backends.
Answered from the vendors’ own pages
Nixpacks: Should I start a new project on Nixpacks?
No. The documentation and README both say it is in maintenance mode and recommend Railpack. Choose Railpack, Cloud Native Buildpacks or a Dockerfile instead.
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.
Nixpacks: Will my existing Nixpacks builds stop working?
Not immediately. Pinned nixpkgs archives keep resolving, so builds continue. What you lose is support for new runtime major versions and any fix for a provider bug.
Soketi: Do I need to change my client code?
No. Pusher client SDKs and Laravel Echo work by changing the host, port and credentials.
Nixpacks: What replaces it?
Railpack, also from Railway and also MIT licensed, rebuilt as a BuildKit custom frontend for finer grained caching and parallel steps.
Soketi: What does it cost?
Nothing in licence fees. It is MIT licensed; you pay for the server it runs on.
Nixpacks: Is it still open source?
Yes, MIT, and the repository is not archived. Being open source does not help much when nobody is merging provider updates.
Soketi: What are people moving to?
Laravel Reverb for Laravel applications, and Sockudo, a Rust reimplementation, for others.
