The short version

  • Each has a real cost: 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.; Testsigma the natural language layer is a fixed vocabulary rather than real English, so testers spend the first weeks learning which phrasings the parser accepts, which is learning a language after all.
  • They diverge on capability: Soketi covers Pusher protocol compatibility, Testsigma covers Natural language authoring.
  • 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.

Soketi

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

Testsigma

  • A team maintaining separate Selenium and Appium suites that wants one place for web and native mobile coveragenot Soketi
  • Organisations that must keep test data and execution on premises for regulatory reasonsnot Soketi
  • QA groups with manual testers being asked to automate without first learning Javanot Soketi
  • Evaluating low code test automation properly before committing budget, by running the free edition against the real applicationnot Soketi

Where each one falls short

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

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.

Testsigma

  • The natural language layer is a fixed vocabulary rather than real English, so testers spend the first weeks learning which phrasings the parser accepts, which is learning a language after all.
  • Anything conditional or arithmetic falls through to custom Java or JavaScript, and that code lives in the platform editor rather than your repository, where it gets no code review and no version history you control.
  • The community edition lags the cloud product and is not the version the vendor demonstrates, so a self hosted evaluation can understate or overstate what you would actually buy.
  • Cloud execution is billed separately from authoring seats, so a suite that grows from two hundred to two thousand tests changes the bill without anyone changing the plan.
  • Support and engineering are concentrated in Indian time zones, which slows incident turnaround for teams working in the Americas.

Answered from the vendors’ own pages

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.

Testsigma: Is the open source edition genuinely usable in production?

Yes for self hosted execution, though it trails the cloud version on newer features and you maintain the grid yourself.

Soketi: Do I need to change my client code?

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

Testsigma: Do testers need to know Selenium?

Not to write ordinary steps. They will need someone who does as soon as the suite needs custom functions or awkward waits.

Soketi: What does it cost?

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

Testsigma: Can it test native iOS and Android applications?

Yes, through Appium underneath, on the hosted device grid or your own devices.

Soketi: What are people moving to?

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