Self-hosted, single-binary cluster cost optimization — learn workload behavior, rightsize every container, and safely bin-pack nodes away. An open-source alternative to CAST AI, ScaleOps and PerfectScale that runs entirely in your infrastructure. Real output: a 4-node kind cluster analyzed in two seconds — $140/month of savings found, PDB-safe. --- Why Kilter Most clusters run at 10–30% of requested capacity . Commercial optimizers fix that by shipping your cluster topology to their SaaS and charging a share of the savings. Kilter does the same control loop — observe → learn → decide → act — as a single Apache-2.0 binary you run yourself: --- --- 🧠 Central brain, your infra One brain optimizes many clusters. Air-gapped friendly: no data leaves your network, no per-cluster SaaS bill. ⚡ Zero-install analyze kilter analyze + any kubeconfig = instant cost, waste and savings report. No agents, read-only. 📐 VPA-grade rightsizing Decaying-histogram percentiles per container (CPU p95, memory peak), OOM-aware floors, HPA interplay handled, confidence scores. 📦 Safe bin-packing A real scheduling simulator (taints, affinity, anti-affinity, topology spread, PDBs, DaemonSet overhead) proves every pod fits before a node is touched. 🛡️ Safety envelope Dry-run by default. PDB reservations, eviction budgets, cooldowns, cluster headroom floor, and automatic revert when a change causes OOM/crashloop. 🔁 In-place resize On Kubernetes ≥1.33, r","default_branch":null,"files":null,"tree":[],"storefront":"/r/agenticode","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/agenticode/kilter/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
