Cast AI optimizes the invoice. PerfectScale optimizes the system.
// CAST AI
Cost-centric automation
CAST AI is designed with a strong focus on cost reduction, aggressively adjusting resources in ways that may introduce production risks for engineering teams. Relying on runtime signals without accounting for code revisions, it makes decisions based on historical behavior that may no longer reflect the current workload, introducing unsafe resource changes. "Sometimes the suggestions are too aggressive for nodes and it may lead to workload discrepancy." — G2 review
// PERFECTSCALE
Reliability-first, performance-driven
- PerfectScale calls it "responsible cost optimization for responsible adults”. PerfectScale is built with reliability in mind: by continuously right-sizing resources and bringing performance into every optimization decision, it helps teams achieve cloud savings without compromising stability, giving engineering teams the confidence to optimize in production.
- PS! PerfectScale is backed by the DoiT platform.Full cloud bill in scope, with cloud experts included. It's an asymmetry point-solution that competitors can't match.

What they say
“Without PerfectScale by DoiT, I don't know how we would do it. We'd have to have twice the number of people on my team to stay on top of it. With PerfectScale, we can focus on the more strategic issues.”
David Adkins, Director of Software and Platform Engineering
PerfectScale by DoiT has become an important part of how we optimize Kubernetes at scale at OneFootball. It gives our platform team the visibility, automation, resiliency insights, and confidence we need to balance cost efficiency with production readiness, especially as we prepare for major global football moments like the 2026 FIFA World Cup.
Andrea Benfatto, Platform/Cloud Runtime Engineering Manager
PerfectScale cut 40% off our total EKS spend, and the automations handle what used to take our team 20 hours a month. Now we spend that time on reliability and performance instead of chasing cost metrics.
Caio Cristo, Director of Infrastructure/SRE
Every customer has unique usage patterns. Manual resource optimization simply didn't scale—we needed automation to ensure every customer, regardless of size, had right-sized infrastructure without consuming our team's capacity.
