What it does
Bring your inventory
Upload a CSV or Excel export — or type a few VMs in by hand.
Common header names (vCPUs, RAM,
Hostname) are mapped for you, and memory in MB is
converted automatically.
Right-size, not just match
Get a like-for-like instance, an optimized one, or both. The optimizer resizes on actual CPU and memory utilization instead of copying whatever the VM runs on today.
Rules that reflect reality
Environment, OS, workload, compliance, and minimum-generation columns drive the recommendation — no burstable instances in production, SAP-certified shapes for SAP, and so on.
Tells you why nothing matched
When a filter excludes every candidate, the nearest miss names the filter responsible — and offers to relax it and regenerate in one click.
Exports people can use
Results as CSV or styled Excel, a per-application rollup, a no-match worksheet to fix and re-upload, and a bulk template for the AWS Pricing Calculator.
Works offline
Installable as an app, and usable without a network once the regions you need are cached. Dark mode and keyboard navigation throughout.
What's new: one-click filter relaxing, a resources-saved summary, copy-to-clipboard on results, and UTF-8-correct CSV exports. See the full changelog →

Nothing leaves your browser
Your inventory is read and analyzed entirely on your own machine. The file is never uploaded, there is no backend, and no server ever sees your data — the only requests this site makes are for its own static files, such as the instance data for the regions you look at.
Only your own settings are kept, in this browser's local storage: theme, saved filter presets, confirmed column mappings, usage counts, and any VMs you type in by hand. Clearing your browser data removes them.
