Windmill vs Prowler: at a glance
What is Windmill?
Windmill let its AI build deployable drafts, then handed two paid runtimes to the free tier.
Windmill is a developer platform for scripts, flows and internal apps, shipping near-daily and with most of this window aimed at two things: an AI chat that has grown into a full authoring session, and the git and workspace plumbing that gets what it produces into production. AI sessions went to beta enabled by default in July, and BigQuery and Snowflake moved out from behind the Enterprise license in the same week.
What is Prowler?
Prowler's agentic defender arrives — and it lives entirely behind the subscription line
Prowler is a cloud security posture platform with an open scanner at its base and a hosted product above it. The recent releases are dominated by Lighthouse AI, which arrived in 5.33.0 as an agentic assistant wired to the Prowler Cloud backend that discovers and runs Prowler's own tools to answer questions about findings, compliance posture and risky resources, then gained a persistent side panel in 5.35.0. Every one of these features carries the same note: available exclusively in Prowler Cloud and Prowler Private Cloud with a subscription. The 5.34.0 release renamed the product family to match that structure.

◆ Current state
Windmill is a developer platform for scripts, flows and internal apps, shipping near-daily and with most of this window aimed at two things: an AI chat that has grown into a full authoring session, and the git and workspace plumbing that gets what it produces into production. AI sessions went to beta enabled by default in July, and BigQuery and Snowflake moved out from behind the Enterprise license in the same week.
◆ Where it's heading
The AI thread and the deployment thread are converging on one workflow. Sessions produce scripts, flows and apps as drafts reviewed in a unified diff drawer; git sync now deploys from a tracked branch in-app and posts a diff check on pull requests; Compare & Deploy targets any workspace rather than only the parent. The result is a path where AI-generated work is reviewed as a diff and promoted like code — which is a bet that the constraint on AI authoring is trust in the review step, not generation quality.
◆ Prediction
Expect AI sessions to move from beta toward default, and further work on the review-and-promote path they feed, since every release in this window touched one or the other. What happens to the remaining Enterprise-only runtimes, Oracle DB and MS SQL, is not indicated.

Prowler's agentic defender arrives — and it lives entirely behind the subscription line
◆ Current state
Prowler is a cloud security posture platform with an open scanner at its base and a hosted product above it. The recent releases are dominated by Lighthouse AI, which arrived in 5.33.0 as an agentic assistant wired to the Prowler Cloud backend that discovers and runs Prowler's own tools to answer questions about findings, compliance posture and risky resources, then gained a persistent side panel in 5.35.0. Every one of these features carries the same note: available exclusively in Prowler Cloud and Prowler Private Cloud with a subscription. The 5.34.0 release renamed the product family to match that structure.
◆ Where it's heading
The direction is a platform sorting its value above the scanner. Findings are becoming workflow objects rather than report rows — grouped or separate Jira issues carrying Prowler context and deep links — while the AI layer moves from a page you visit to a panel that follows you through the app. The patch releases underneath tell the other half of the story: Attack Paths graph mutations retrying Neptune concurrency failures, bounded node identifiers to avoid Neo4j index key limits, deterministic upsert ordering to prevent PostgreSQL deadlocks. That is a graph-backed analysis engine being scaled under load while the differentiated surface is built on top.
◆ Prediction
Expect Lighthouse AI to keep absorbing workflow actions — ticketing, remediation suggestions, compliance queries — and for the gap between the open scanner and the subscription platform to keep widening.
