Prowler vs Semgrep: at a glance
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 Semgrep?
Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.
Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

◆ 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.
Semgrep
5.0INFRA · APIS
Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.
◆ Current state
Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.
◆ Where it's heading
The performance work is converging on one problem: very large monorepos. File targeting now batches path filtering across worker domains, rule parsing shards by bytes instead of worker count, and a new Pro memory policy lets a scan trade RAM for skipping on-disk caching. Running alongside it is a quieter thread of trust work, and the 1.173.0 fix for silently dropped targets belongs to it: a file whose path filtering failed appeared in neither the findings nor the skipped list, which is the kind of gap that undermines a scan report more than any missing rule.
◆ Prediction
Expect the parser-refresh-plus-throughput cadence to continue, with the memory policy and the dependency-path output likely graduating out of experimental once large-repo users report back on them.
