Where each one falls short

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

Garden

  • Incredibuild acquired Garden in November 2024 and the pricing page now redirects to documentation, so there is no public commercial offer and no published roadmap for a team betting a platform on it.
  • It is tightly bound to Kubernetes, so teams running on ECS, Nomad, plain VMs or serverless get little from it and would need a different tool entirely.
  • The YAML action graph is a real configuration surface: a large monorepo needs someone to own and maintain Garden config as a first-class artefact, which is a standing platform-engineering cost.
  • Shared remote environments mean every developer needs cluster access and a cost allocation model, so cloud spend rises and namespace sprawl becomes a thing you have to police.
  • Caching correctness depends on declaring dependencies accurately; an under-declared action will serve a stale cached pass and hide a genuine test failure, which is a hard class of bug to notice.

Tenable Nessus

  • Nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee
  • Support beyond the base entitlement costs an extra $400 per year for Advanced Support with 24x365 phone and chat access
  • The on demand training course is a separate $275 purchase for a single person for one year
  • Multi year discounts require paying for two or three years up front
