UTILITYFORGE / LOCAL-FIRST TOOLS
Calculate, convert, format, inspect, and generate in your browser. Local tools keep your input on this device, while every network feature names what it sends. Methods, limits, and sources are always visible.
WHAT ARE YOU TRYING TO DO?
Local workbenches keep input in this browser
Every item in the registry runs now. Live data and API records keep their honest release state — labelled, bounded, and never presented as local processing.
How we publish01 / PERSONAL RECORD
Saved tools, recent work, and run counts stay on this device by default. Signing in is optional. If you explicitly enable workspace sync, eligible saved workspace data is copied to your account; tool inputs and results are never automatically synchronized.
Nothing saved yet. Open any tool, bookmark it, and this band becomes your personal shortlist — kept in this browser until you choose to sync it to your account.
02 / REGISTRY FAMILIES
12 families partition the catalog: every workbench belongs to exactly one, and every record listed runs today. Subject collections and network surfaces are mapped separately on the category index.

Decode a JWT header and payload without verifying it.
04 / THE STANDARD
Local workbenches execute in your browser: your values are not uploaded, logged, or sold. Network surfaces state exactly what they send before you run anything, and the processing mode is printed on every tool page.
Every result ships with the formula or transform that produced it, the limitations that apply, and the date it was last reviewed.
Planned categories stay sealed. We do not fill the directory with shells that look finished and quietly do nothing.
05 / BEYOND THE BROWSER
Three guarded surfaces handle the work that genuinely cannot run locally. Each one is bounded, labelled, and refuses to present stale data as live.
A hardened, allowlisted request surface with DNS pinning, private-IP blocking, redirect revalidation, and explicit execution consent.
PROVIDER / DATEDCurrency, weather, time zones, and crypto from named upstream providers, each stamped fresh, stale, or unavailable — never disguised.
