Small utilities. Properly made.

Underground Stack is an independent project building useful online tools for sellers, makers, and people who want to finish practical tasks without complicated software.

We prefer a few dependable products over an enormous directory of low-quality pages. Listing Image Studio prepares consistent listing-ready product images. Market Closeout Studio helps vendors reconcile post-event inventory, identify discrepancies, and plan restocking. BOM Revision Inspector compares two flat engineering bills of materials and flags changes. Cable Run Label Studio generates matched cable labels and registers. Wallpaper Drop & Roll Planner creates conservative, pattern-aware cutting worksheets for rectangular wall sections. Bookmark Merge Desk combines HTML bookmark exports with explicit duplicate decisions and reversible project files.

Wallpaper Drop & Roll Planner builds numbered cuts per physical roll, with clear match assumptions and printable worksheets.

Bookmark Merge Desk lets you inspect merge decisions before importing the resulting HTML file into a browser.

How we build

Where possible, tools operate inside the browser instead of transmitting personal files to our servers. We aim for clear limits, accurate descriptions, straightforward controls, and free core functionality without registration.

How the project is supported

Underground Stack operates an Etsy shop with optional paid digital products. Tool pages may reference relevant products, always separately from free functionality. Advertising may be considered in the future, but this release does not serve advertising.
