What is Prowler?

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

What is Trunk?

Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.

Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

◆ Current state

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Where it's heading

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.

◆ Prediction

Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.

Trunk is methodically maturing Merge Queue and Flaky Tests into enterprise-grade CI infrastructure.

◆ Current state

Trunk's recent work is almost entirely incremental hardening of its two core products: Merge Queue and Flaky Tests. The cadence shows a clear enterprise-readiness pattern — a Terraform provider, public API endpoints, Prometheus-compatible metrics, multiple queues per repo, and deeper Slack and Jira integration. Nothing here redefines the product; it's the steady filling-in of operational and integration gaps larger teams require.

◆ Where it's heading

Trunk is making Merge Queue programmable and observable: APIs, IaC, metrics endpoints, and richer dashboards point at customers who manage CI at scale and want it wired into their existing tooling. Flaky Tests is gaining automation hooks (Jira issue creation, configurable threshold monitors) that move it from detection toward workflow.

◆ Prediction

Expect continued API, metrics, and integration depth on Merge Queue, and more automated remediation paths for Flaky Tests, as Trunk leans into programmability for larger engineering orgs.
