Azure VM sizing, price comparison, Kubernetes planning, Linux helpers, licensing estimators, and compact operational utilities for actual technical workflows.
Built for engineers who need answers fast, not platforms that need sign-ups to show you a CIDR table.
Every tool is open and usable immediately. No sign-up, no email, no paywall.
No banners, no sponsored results, no distractions. Just the tool and the answer.
Search, filter, and get to the right tool in seconds — not after scrolling past marketing copy.
Inputs and outputs are in the units you actually use: vCPUs, GiB, CIDR blocks, octal permissions.
Each tool does one thing well. No bloated multi-purpose pages that half-answer ten questions.
See every live and planned tool at once — statuses, categories, and links all in one place.
Best current entry points into the platform.
Host sizing, VM planning, and infrastructure estimation for Hyper-V environments.
Convert chmod values between numeric and symbolic notation, explore permissions with an interactive grid, compare two values side-by-side, and get risk indicators and an octal breakdown.
Calculate Linux umask results for files and directories, reverse target permissions back to the required umask, and inspect live previews, permission cuts, and shareable outputs.
Compare Azure VM pay-as-you-go and reserved pricing scenarios using practical runtime and instance-count assumptions.
Find Azure VM sizes based on practical workload requirements.
Compare monthly, annual, and full-term cost for reserved versus on-demand pricing under practical workload usage assumptions.
Choose your engineering role to jump directly to the tools that are most relevant for your day-to-day work.
