About BitKitTools
What We Offer
BitKitTools is a free collection of micro-calculators built for developers, travelers, beer lovers, and parents. Every tool is designed so you can find what you need through a quick search and start using it immediately — no login required.
All calculations run instantly in your browser. We have no server-side processing or database, and sensitive inputs are never transmitted anywhere.
Tool Categories
Developer Tools
Quickly run everyday utilities like a JSON Formatter & Validator and a secure Password Generator — tools that developers reach for constantly.
Travel Tools
Calculate potential flight delay compensation under EU261 and other regulations, or check visa requirements for country combinations — practical help for trip planning and problem-solving.
Beer Tools
Estimate blood alcohol concentration (BAC) using the Widmark formula, or calculate ABV and dilution ratios for homebrew recipes. The BAC Calculator is for informational reference only and must not be used to determine whether it is safe to drive.
Baby Tools
Check your baby's growth percentile against WHO and CDC standards, or plan daily nap and bedtime schedules by age. All results are for reference only — always consult a pediatrician.
How We Operate
BitKitTools is funded by Google AdSense advertising. Ads are placed in designated layout slots and are managed so they do not interfere with content quality.
Tools covering medical, legal, or financial topics cite their data sources (WHO, CDC, EU261, etc.) and are carefully designed to avoid making definitive judgments in their results.
