Kubera continuously right-sizes pods, tunes autoscaling, bin-packs nodes, and shifts safe workloads to spot — with guardrails that auto-roll-back before anything breaks. You ship; Kubera keeps the bill honest.
Most tools do one thing. Kubera closes the whole loop: see the waste, decide the change, apply it safely, and prove the savings landed.
Requests & limits set from real cAdvisor history (P90/P95), per container — not guesses. Frees the stranded reservation you pay for.
Creates and tunes HPAs for you — target utilization, min and max replicas — and routes CPU scaling to the HPA so you never fight a death spiral.
HPA min/max derived from a 30-day demand curve (peak ÷ per-pod capacity), with provenance — not a snapshot. Real numbers, shown.
Classifies which workloads are spot-safe, places them on spot with on-demand fallback, and excludes reclaims from rollback decisions.
Turns freed requests into a smaller bill: Karpenter-aware compaction that drains under-utilized nodes — and tells you what's blocking it.
Finds pods pinning nodes (local storage, strict PDBs) and recommends create/relax so consolidation can actually proceed.
Continuously retunes the instance band to your fleet's real shape and emits a ready-to-apply Karpenter NodePool.
Savings Plan / RI utilization & coverage from Cost Explorer — flags idle commitments and uncovered on-demand to absorb.
Every change is watched. OOM, CPU throttling or an SLO breach reverts it automatically before the window closes.
A tiny agent ships only the metrics Kubera needs to a hosted endpoint. Your usage data drives the recommendations; you stay in control of what gets applied.
One kubectl apply. An allowlisted Prometheus agent scrapes ~6 metric families and remote-writes them out — no AWS credentials in your cluster.
kubectl apply -f \\
https://app.getkubera.io/install/agent.yamlIt builds a real usage & demand history per workload — peaks, troughs, seasonality — and computes the safe change for each lever, with the evidence behind it.
Approve once, or turn on Auto. Kubera applies changes within your policy, watches the result, and rolls back on any regression. Savings show up on the bill.
Rightsizing vendors don't touch nodes. Node vendors don't tune your HPAs. Observability tools just watch. Kubera does the full loop — and shows its work.
