The short version

  • Each has a real cost: Flask requires manual configuration of many common features like authentication, ORM, and admin panels; 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.
  • They diverge on capability: Flask covers Lightweight framework, Steampipe covers SQL over live APIs.
  • Prices and features above were last checked on 31 August 2026.

Steampipe

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

Where each one falls short

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

Flask

  • Requires manual configuration of many common features like authentication, ORM, and admin panels
  • No built-in admin interface or scaffolding tools
  • Minimal built-in security features compared to full frameworks

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.

Answered from the vendors’ own pages

Flask: Is Flask free to use?

Yes. Flask is open-source software released under the BSD-3-Clause License, available free for any use including commercial applications.

Source
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.

Flask: What are Flask's core dependencies?

Flask depends on three main libraries: Werkzeug (WSGI toolkit), Jinja (template engine), and Click (CLI toolkit).

Source
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.

Flask: Does Flask provide built-in database support?

No. Flask is a microframework that does not include built-in database support. Developers must choose and integrate their own database libraries, though Flask-SQLAlchemy is a popular community extension.

Source
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.

Flask: What platforms does Flask support?

Flask is a microframework for Python that runs on any platform that supports Python, including Linux, macOS, Windows, and cloud platforms.

Source
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.

Flask: Can Flask scale to large applications?

Yes. While designed to be lightweight and simple, Flask is designed with the ability to scale up to complex applications through blueprints, extensions, and modular architecture.

Source
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.

Flask: Does Flask require a build step to run?

No. Flask does not require a build step. Applications can run directly with the Flask development server using 'flask run' from the command line.
