A growing collection of browser-based utilities from zygig. Every tool here runs entirely client-side — nothing you enter is ever uploaded, stored, or tracked. Open one, use it, close the tab.
SharePoint Online version-management script generator
File versions quietly eat a tenant's storage quota. This tool builds the PowerShell for you: fill in a site URL, pick a job, and copy out a ready-to-run script for intelligent versioning, storage cleanup, auditing, or bulk operations across every site in the tenant. It only needs the SharePoint Online Management Shell — no extra modules — and the scripts are generated in your browser, so no URL, tenant name, or setting is ever sent anywhere.
New free, client-side utilities get added here regularly. Watch the repo on GitHub to hear about them first.
All processing happens locally in JavaScript. No servers, no uploads.
No cookies, no analytics, no third-party scripts.
No sign-up, no paywall, no usage limits.
Every tool is a single readable HTML file you can inspect on GitHub.
Suggest it — or build it. Each tool is one self-contained HTML file under tools/, so contributing is a single pull request.
