Six tools. Less routine work.
Each workspace follows its own workflow, with local processing and files you can download and inspect.
Open tool ↗
Market Closeout Studio
Reconcile craft fair stock against sales and physical counts, review discrepancies, then export a restocking checklist.
BOM Revision Inspector
Compare manufacturing bills of materials across revisions. Identify added parts, quantity shifts, specification edits, and cost changes with a downloadable review report.
Cable Run Label Studio
Make matching printable cable flags for both ends of every documented connection, with a measured PDF and traceable CSV register.
Wallpaper Drop & Roll Planner
Calculate full-height wallpaper drops, trace pattern matching and download roll-by-roll cut worksheets and a strip register.
Bookmark Merge Desk
Combine browser bookmark exports, review duplicates instead of blindly deleting them, and download an importable HTML library with a CSV audit trail.
Built on a simple idea
Less busywork. More doing.
Useful on the first visit
Open a tool, finish a task, and leave. No account creation or subscription gate.
Your work stays yours
Tools process your work inside your browser. No photo, inventory, BOM, cable-run or bookmark files are uploaded to our servers.
Designed for the details
Thoughtful presets, clear choices, and exports you can inspect instead of mystery settings.
Independent and improving
A better tool is worth keeping.
Underground Stack is a small independent project focused on building useful utilities rather than publishing hundreds of placeholders.
