Blackglass Tools

Free utilities for Linux fleets and cloud accounts

Pre-scan planning tools you can run in the browser — no signup, no credentials. They give you a defensible starting point; real scans, approvals, and history live in Blackglass and Charon.

Cloud Waste Estimator

Estimate how much you might be wasting on idle droplets, ghost volumes, and old snapshots — without API keys.

A pre-scan planning tool aligned with Charon in Blackglass — same categories, rough self-reported inputs, no credentials. For continuous multi-cloud scans with approval-gated cleanup, use Charon itself.

Privacy: the free estimator never requests, stores, or processes cloud credentials, hostnames, or live resource identifiers. Counts and costs never leave your browser unless you choose to email yourself the summary.

    No unattached volumes entered — no orphaned volume estimate.

  • Old snapshots$0–$0/mo

    No old snapshots entered — no snapshot waste estimate.

What to do next

  • Tag everything you keep — environment, owner, expiry — so the next sweep takes minutes instead of hours.
  • Schedule the sweep monthly. Cloud waste creeps back in faster than most teams expect.

We never log resource IDs or credentials — just the totals you see here.

What this tool does — and doesn’t

  • All maths runs in your browser. Counts and costs never leave your device unless you choose to email yourself the summary.
  • No credentials, hostnames, or resource IDs. The form only accepts generic counts and per-unit prices.
  • Directionally useful, not authoritative.The coefficients are intentionally approximate and calibrated for educational estimation, not production-grade classification — real bills depend on instance type, region, reservations, and savings plans an estimator can’t see.
