I got tired of modern web utility calculators that are cluttered with 15 ad banners, cookie popups, and paywalls locking simple PDF downloads behind an email signup.

So I launched ZeroBloatTools — a collection of 12 specialized, 100% client-side utilities that run entirely in the browser with zero server uploads, no logins, and zero tracking.

What's Inside:

3-Way & 4-Way Switch Simulator: Interactive animated AC circuit visualizer showing traveler conductors in multi-switch wiring.
Stair Stringer Calculator: 2D elevation framing visuals and IRC/IBC building code checks.
4×6 Thermal Label Cropper: Rotates and crops 8.5x11 PDF shipping labels for Rollo, Munbyn, and Zebra thermal printers locally in canvas.
cURL to Playwright & k6 Converter: Converts raw cURL to clean test scripts with automated secret masking.
Home EV Charger & Panel Load Calculator: NEC 220.82 residential capacity solver.
CAT Scale Trailer Tongue Weight Calculator: 2-pass & 3-pass ticket solver with sway risk dynamics.
BRRRR Real Estate Deal Analyzer: Models rehab, holding costs, and DSCR qualification with 1-click printable bank sheets.
Audio Delay & Reverb Studio: Milliseconds, LFO frequencies (Hz), and DAW buffer offsets.

Everything is built with Next.js static export and hosted on Cloudflare Pages for instant worldwide performance.
