Mathsway - Free Online Integral & Derivative Calculator

Hi Product Hunt community! I am incredibly excited to share **[Mathsway](https://mathsway.net/en/)**, a completely free, browser-native math engine designed to solve integrals, derivatives, and limits with full step-by-step logic. What inspired Mathsway? Most advanced calculus solvers rely heavily on external server processing. They often mandate paid paywalls, track user data, or require annoying account registration. I wanted to build a tool that makes learning advanced calculus universally accessible, lightning-fast, and completely private. The Problem We Are Solving Students and professionals need quick mathematical validation without compromising data or budget. * High premium subscription costs. * Intrusive tracking of user queries. * Heavy server-side loading delays. How the Tool Evolved Initially, we thought about a traditional web application infrastructure. However, we shifted completely to a serverless model. Mathsway now runs entirely on your device using Web Worker technology. Core Features * **Zero tracking**: No accounts or databases. * **Pure privacy**: Calculations stay on your device. * **Browser-native speed**: Powered by local Web Workers. * **Step-by-step solutions**: Understand the "how" and "why". I would love to hear your thoughts, feature requests, or bugs you encounter. Please give it a spin and leave your feedback below! Thank you for your support!
