Hey Product Hunt community! 👋
We built Locolory Utility Tools to solve a personal frustration: whenever you need a quick calculation (like optimizing sheet cuts for woodworking, sizing a concrete slab, calculating eBay seller fees, or parsing a cron job), legacy search results force you through paywalls, forced email signups, intrusive banner ads, or slow server reloads.
We decided to build an "Engineering as Marketing" toolkit where every utility runs 100% client-side in your browser:
⚡ Zero Accounts or Logins – Instant utility without forms or onboarding.
🔒 100% Private & Local – Calculations and data never leave your browser memory.
📐 Direct Visuals & Exports – SVG cut diagrams, @media print stylesheets, and one-click CSV downloads.
⚡ Built for Speed – Hosted on edge CDN with zero backend latency.
Key tools in the collection include:
- Fabrication & Trades: 2D Cut List Optimizer, Stair Stringer Layout, Board Foot Lumber, Concrete & Rebar Sizer, Roof Pitch.
- E-Commerce & Business: eBay Fee Calculator, Etsy Pricing Math, Stripe Reverse Invoicing, Shift Roster Generator, Tip Pooling.
- DevOps & Developers: Cron Expression Generator, JSON to TypeScript/Zod, CIDR Subnet Calculator, Unix Timestamp Converter.
It’s completely free, and we’d love to hear your feedback, tool suggestions, or bug reports!
