The short version

  • Only Moonrepo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Moonrepo smaller community compared to established build systems like Bazel; Qualys VMDR licensing is per asset and each capability is its own subscription, so patch management, endpoint detection, web application scanning, container security and policy compliance are separate line items, and the platform demonstrated in a proof of concept is rarely the platform in the quote.
  • They diverge on capability: Moonrepo covers Task orchestration, Qualys VMDR covers Cloud Agent.
  • Prices and features above were last checked on 30 August 2026.

  • PCI DSS external scanning where an approved scanning vendor report is a contractual requirementnot Moonrepo

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Moonrepo

  • Smaller community compared to established build systems like Bazel
  • Limited integrations with enterprise CI/CD platforms
  • Documentation gaps in some advanced use cases
  • No commercial support option for organizations requiring guaranteed SLAs

Qualys VMDR

  • Licensing is per asset and each capability is its own subscription, so patch management, endpoint detection, web application scanning, container security and policy compliance are separate line items, and the platform demonstrated in a proof of concept is rarely the platform in the quote.
  • Ephemeral cloud instances consume asset entitlement until they age out of inventory, so an autoscaling group that creates and destroys hosts hourly can burn licence capacity on machines that existed for minutes, and controlling that means tuning purge policies rather than tuning the cloud.
  • Authenticated scanning produces materially better results than unauthenticated, but it requires storing and rotating privileged credentials for every target platform, which is a security project in its own right, and teams that skip it receive reports full of unconfirmed potential findings that nobody trusts.
  • The console is a set of modules with separate interfaces, search syntaxes and report engines, so an analyst moving between vulnerability management, policy compliance and web application scanning learns each one, and cross-module reporting usually ends in a spreadsheet or a script against the API.
  • The tool surfaces findings far faster than any organisation can remediate them, and it does not solve the ownership problem: without an agreed prioritisation policy and a named owner in IT operations, a first scan producing tens of thousands of findings becomes a dashboard that everyone learns to ignore.

Answered from the vendors’ own pages

Moonrepo: What programming languages does Moonrepo support?

Moonrepo's proto version manager supports Node.js, Python, Go, Rust, Deno, Java, Ruby, and other languages, with the build system moon supporting most modern development stacks.

Source
Qualys VMDR: Agent or scanner: which do I need?

Usually both. The agent covers endpoints and servers you control and gives continuous data; scanners cover devices you cannot install an agent on, such as network gear, printers and appliances, and provide the external perimeter view.

Moonrepo: Is Moonrepo suitable for large monorepos?

Yes, Moonrepo is designed to scale to monorepos of any size with intelligent caching and task orchestration to maintain build performance.

Source
Qualys VMDR: Does it patch as well as detect?

Yes, through the Patch Management module, which is a separate subscription using the same agent. Core VMDR detects and prioritises but does not deploy fixes.

Moonrepo: Can I use just moon or just proto separately?

Yes, moon and proto are independent tools that can be adopted separately or together to address specific team needs.

Source
Qualys VMDR: How are assets counted for licensing?

By the number of assets in inventory, which includes cloud instances and containers depending on the modules in use. Short-lived cloud assets count until they are purged, so purge settings directly affect what you consume.

Qualys VMDR: Can I keep the data in a specific region?

Yes. Qualys operates several regional platform instances and you choose which one your subscription lives on. Moving between them later is not trivial, so decide before onboarding.

Qualys VMDR: Does it scan web applications?

Web Application Scanning is a separate module licensed per application, not part of core VMDR, and it is a dynamic scanner with the usual limits around authenticated flows in single-page applications.
