Also searched as Steampipe + Powerpipe vs Prowler — same comparison, one verdict.
Prowler and Steampipe + Powerpipe are closely matched on ownership (92 vs 86) — this one comes down to pricing and to which trade-offs below you can live with.
Prowler
TOP PICKOpen-source cloud security posture scanning with framework check packs.
Scans AWS, Azure, GCP and Kubernetes against hundreds of checks and maps them to compliance frameworks including CIS, SOC 2, HIPAA, GDPR and NIST. Runs as a CLI in CI or as a self-hosted app, and produces the technical-control evidence a compliance platform would otherwise gather for you.
Steampipe + Powerpipe
Query your cloud configuration as SQL, with compliance mods on top.
Steampipe exposes cloud and SaaS configuration as SQL tables; Powerpipe runs benchmark mods against them, including CIS, SOC 2, HIPAA and PCI packs. The most flexible option here — if you can express a control as a query, you can check it continuously.

Prowler
Strengths
- +Framework mappings are built in — SOC 2, CIS, HIPAA, GDPR, NIST and more, not just raw findings
- +Runs in CI, so posture is checked on every change rather than the week before an audit
- +Covers the part of compliance that is genuinely automatable: technical control state
Trade-offs
- −Produces evidence, not an audit — no auditor relationship, no report
- −No policy management, security training tracking or vendor review workflow
- −Someone has to own the findings; the tool will not chase them
Steampipe + Powerpipe
Strengths
- +SQL over live cloud state is unusually powerful for bespoke controls
- +Large library of community compliance benchmarks
- +Composes well with existing data tooling rather than being another silo
Trade-offs
- −Assumes comfort with SQL and with defining your own controls
- −Split across two tools since the 2024 Powerpipe separation
- −No evidence archive, policy engine or auditor-facing output
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Prowler
if a lower exit cost matters more to you than any single feature, and framework mappings are built in — SOC 2, CIS, HIPAA, GDPR, NIST and more, not just raw findings.
Choose Steampipe + Powerpipe
if sQL over live cloud state is unusually powerful for bespoke controls.
Neither, yet
if both carry a real cost you should weigh first — produces evidence, not an audit — no auditor relationship, no report, and assumes comfort with SQL and with defining your own controls. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
Prowler vs Steampipe + Powerpipe — common questions
Is Prowler a better fit than Steampipe + Powerpipe for compliance automation & security posture?
It depends on what you are optimising for, and the honest split is this: Prowler scores 92 to Steampipe + Powerpipe's 86 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Steampipe + Powerpipe earns its place on a different axis — sQL over live cloud state is unusually powerful for bespoke controls. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Prowler keeps its data local or in open formats, so leaving is an export rather than a negotiation. Steampipe + Powerpipe is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Prowler or Steampipe + Powerpipe?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Prowler and Steampipe + Powerpipe both alternatives to Vanta?
Yes — both appear in our Vanta comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Vanta and now choosing between the two replacements, which is a narrower and much easier question.
