No signup. No upload to anyone's server. No "free trial that becomes a subscription." Just instant tools that solve one specific problem each, fast — for sellers, developers, Minecraft builders, and anyone who'd rather not hand over their email for a calculator.
Fee calculators and formatting utilities, country-aware where it matters.
Replace paid Shopify apps with free, browser-only equivalents.
Browser-based utilities for everyday dev work. No data leaves your device — safe for timestamps from private logs or production secrets.
<t:UNIX:F> tags for Discord messages. All seven format codes with live previews. Each viewer sees the time in their own zone, automatically.Builds, math, design, and planning for Minecraft players — build templates that don't fit a square grid, plus calculators and designers that save real time at the loom, anvil, and enchanting table.
Size a solar setup, convert battery units, and check runtimes — for vanlife, RVs, off-grid cabins, and backup power. Uses the same formulas installers do, with the assumptions shown so you can adjust them.
Decode resistors, size wire and conductors, check voltage drop, and solve Ohm's law — bench-and-field references for hobby electronics, automotive, and low-voltage DC. Every value is computed live in your browser, with the formula shown so you can check it.
Turn box dimensions into the weight carriers actually bill you for. Both tools show the working — divisor, rounding, and which weight wins — so you can check a quote instead of trusting it.
Saw-angle math for trim and joinery — worked out with the correct compound-angle geometry, so the numbers hold up on out-of-square corners and sloped-side boxes, not just the textbook 90°.
Estimators for the jobs suppliers sell by the bag, box or roll — concrete, block, gravel and mulch by the yard and ton, plus paint, tile, flooring and wallpaper for finishing a room — each with the real units, waste allowance and the formula shown, and nothing sent anywhere.
Work out what your rig can really tow and how to balance the trailer — from your own door-jamb sticker numbers, with the binding limit named and the physics shown. Nothing is looked up and nothing is sent anywhere.
