regula.tools
Privacy-first, 100% client-side deterministic web utilities for developers, finance, and system operations.
regula.tools is a high-speed suite of privacy-first, deterministic web utilities engineered to execute 100% client-side with zero server data uploads. Reading, converting, or calculating sensitive financial and engineering data should never require sending your payloads to third-party backends. regula.tools eliminates this friction entirely: all computations β from statutory tax calculators (Turkey Tapu HarcΔ±, KDV Tevkifat, freelance SMM) and merchant fees (Stripe Fee Calculator 2026) to cryptographic generators (UUID v4/v7, CSPRNG Passwords & Diceware, Cron Expression Visualizer), AST code transformers (JSON to TypeScript, Base64, CSV to JSON/SQL), and syntax beautifiers (JSON, SQL) β run purely inside your browser using Web Workers and the Web Crypto API. Designed with zero marginal server costs, zero telemetry, and compressed URL hash state sharing, regula.tools delivers maximum speed, absolute data confidentiality, and reproducible calculations anywhere.
Core Features & Capabilities
100% Client-Side & Zero Upload
All simulations, conversions, and cryptographic operations execute on-device via Web Workers and Web Crypto CSPRNG. No sensitive data ever leaves your browser.
Deterministic & Shareable
Deterministic algorithms ensure mathematically reproducible outputs with compressed URL hash state and deep-linkable parameters for effortless team verification.
Broad Utility Catalog
Statutory calculators (Stripe, Tapu, KDV, SMM), generators (UUID v4/v7, Diceware, Cron), AST transformers (JSON to TypeScript, CSV to SQL), and multi-dialect SQL formatters.
Bilingual & Responsive PWA
Full English and Turkish localization, dark-mode optimized ergonomic interface, zero cookie tracking, and offline-capable PWA architecture.
