Authelia vs Prowler
A side-by-side editorial comparison of Authelia and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Authelia vs Prowler: at a glance
What is Authelia?
Authelia's 4.39.x series is a continuous patch stream: five releases in nine days, no new features
Authelia is in a sustained maintenance phase on the 4.39.x branch. The project has shipped at least five releases since September 8 — all bug-fix patches targeting OIDC conformance, web UI edge cases, SMTP IPv6, Envoy authz path handling, and storage correctness. The release cadence is high but the content is narrow: there is no visible feature investment in the recent window.
What is Prowler?
Prowler 5.46 groups scan findings into issues and extends AI checks to Bedrock and Vertex.
Prowler ships a minor release every one to two weeks. 5.46.0 adds an Issues page to Prowler Cloud that groups a scan's findings into issues with a verdict, new AWS Bedrock, Cognito and WAFv2 checks, a five-check Vertex AI Workbench service on GCP, and checks for PHP runtimes left exposed by the PHP2Shell CVEs across AWS, GCP and Azure. Google Workspace checks now account for the tenant's edition and read the policy Google actually applies.

Authelia's 4.39.x series is a continuous patch stream: five releases in nine days, no new features
◆ Current state
Authelia is in a sustained maintenance phase on the 4.39.x branch. The project has shipped at least five releases since September 8 — all bug-fix patches targeting OIDC conformance, web UI edge cases, SMTP IPv6, Envoy authz path handling, and storage correctness. The release cadence is high but the content is narrow: there is no visible feature investment in the recent window.
◆ Where it's heading
The pattern across these releases is OIDC stabilization — multiple entries address consent handling, resource indicators, and JWT grant correctness. Authelia appears to be closing out conformance gaps accumulated during earlier 4.39.x development rather than adding surface area. The active committer footprint is small (primarily @james-d-elliott), which keeps the pace sustainable but limits breadth.
◆ Prediction
Given the absence of feature releases since well before May 2026, a 4.40.x or 5.0 branch with new capabilities is likely being developed in parallel. The current stream is support-mode maintenance.
Prowler
5.0INFRA · APIS
Prowler 5.46 groups scan findings into issues and extends AI checks to Bedrock and Vertex.
◆ Current state
Prowler ships a minor release every one to two weeks. 5.46.0 adds an Issues page to Prowler Cloud that groups a scan's findings into issues with a verdict, new AWS Bedrock, Cognito and WAFv2 checks, a five-check Vertex AI Workbench service on GCP, and checks for PHP runtimes left exposed by the PHP2Shell CVEs across AWS, GCP and Azure. Google Workspace checks now account for the tenant's edition and read the policy Google actually applies.
◆ Where it's heading
The open-source engine keeps absorbing coverage where risk is moving: hosted AI services first on Azure in 5.45, now on AWS and GCP, plus fast responses to named CVEs. The paid cloud product keeps adding triage layers on top, from AI fixes per finding to issue grouping, making the free CLI the data source and Prowler Cloud the place findings get worked.
◆ Prediction
Expect AI-service coverage to keep widening across providers and further Prowler Cloud triage features built on the new issue grouping.
