The short version

  • Each has a real cost: Steampipe aGPL-3.0 across all four engines is a procurement blocker at organisations that ban the licence outright, and the network clause reaches any internal portal or service that puts a web interface in front of it.; TestNG maintainership is concentrated around creator Cedric Beust rather than a broad team or foundation, which is a real continuity risk compared to JUnit's independent team or Jest's foundation backing.
  • They diverge on capability: Steampipe covers SQL over live APIs, TestNG covers Test dependencies.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

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

Steampipe

  • Security teams answering posture questions against live cloud accounts rather than a nightly exportnot TestNG
  • Compliance evidence gathering where the answer must reflect the account at the moment it is askednot TestNG
  • Inventory and drift questions spanning several cloud providers in one querynot TestNG
  • Engineers who would rather write SQL than learn each provider command line toolnot TestNG

TestNG

  • A Java integration test suite that needs to skip dependent tests automatically when a prerequisite test failsnot Steampipe
  • A team wanting XML-based suite configuration to manage large, grouped test suites without touching code for each runnot Steampipe
  • A project needing native parallel test execution at the class or method level without adding a separate pluginnot Steampipe
  • A Selenium-based UI test suite that uses TestNG as the underlying runner for grouping and parallelisationnot Steampipe

Where each one falls short

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

Steampipe

  • AGPL-3.0 across all four engines is a procurement blocker at organisations that ban the licence outright, and the network clause reaches any internal portal or service that puts a web interface in front of it.
  • Dashboards, benchmarks and mods were removed from Steampipe entirely at version 1.0 in October 2024 and now live in a separate product, so pre-2024 documentation and tutorials describe commands that no longer exist.
  • Live querying is bound by cloud provider API rate limits and keeps no persistent store by default, which is why a separate DuckDB-backed product exists for log volumes and why large accounts return slowly.
  • The company is fifteen people and bootstrapped, maintaining four command line tools plus a hosted service plus two further products, and the newer tools have thin community traction relative to that surface area.
  • Hosted tiers include only three users regardless of tier, with additional Enterprise users charged separately, so a team of thirty costs an order of magnitude more than the headline figure before compute and storage are counted.

TestNG

  • Maintainership is concentrated around creator Cedric Beust rather than a broad team or foundation, which is a real continuity risk compared to JUnit's independent team or Jest's foundation backing.
  • It is a smaller ecosystem than JUnit, so fewer third-party integrations, tutorials and Stack Overflow answers exist for edge cases.
  • XML-based suite configuration, while powerful, is an extra file and syntax to maintain alongside the codebase, which some teams find adds friction JUnit's more code-centric model avoids.
  • There is no commercial support tier or vendor relationship of any kind, unlike JUnit's OpenElements arrangement, so an enterprise wanting a support contract has no route to buy one.
  • Release cadence, while active, is slower and less frequent than JUnit 5's, since it depends on a much smaller pool of active maintainers.

Answered from the vendors’ own pages

Steampipe: When did Steampipe become AGPL?

May 2021, about four months after the project went public. It is a settled licence rather than a recent change, and predates the Business Source Licence wave it is often confused with.

TestNG: Is TestNG still actively maintained in 2026?

Yes, it continues to receive releases in its 7.x line with support for current Java versions, though maintenance is concentrated around a small team led by its creator.

Steampipe: Where did the dashboards and benchmarks go?

Into Powerpipe. They were deprecated in March 2024 and removed from Steampipe at version 1.0 in October 2024, so the check, dashboard, mod and variable commands are gone.

TestNG: What does TestNG offer that JUnit does not?

Native test dependencies, XML-based suite configuration and built-in parallel execution without needing external plugins, all of which JUnit users typically add via separate libraries.

Steampipe: Is it fast on a large cloud estate?

Not always. Queries call provider APIs at request time, so rate limits rather than query planning set the pace, and there is no persistent store by default.

TestNG: Is there a commercial support option for TestNG?

No, unlike JUnit there is no commercial support arrangement; support is purely community-based through GitHub.

Steampipe: Does the AGPL affect internal use?

Running it internally for your own analysis is fine. Putting a web interface in front of it that other people use is where the network clause becomes a question for your legal team.

Steampipe: Is a bootstrapped vendor a risk?

It cuts both ways. There is no investor pressure toward a licence change or an exit, and there are also fifteen people supporting a large product surface.
