LaiUse is a free, browser-based productivity tool platform with 178 tools across 12 categories including Developer, Network, SEO, PDF, Media, Privacy, AI, Utility, QR & Links, Security, and Singapore. We believe powerful tools shouldn't require downloads, sign-ups, or payments.
Every tool on LaiUse runs entirely in your browser. Your files, images, and data never leave your device — making LaiUse one of the most privacy-friendly options for online tools. No accounts required, no data stored, no hidden fees.
From QR generators to network diagnostics, LaiUse covers the utilities developers, designers, and everyday users need — all free, all instant.
LaiUse is built with React and Vite for a fast, responsive experience. Server-side tools run on Node.js with Express and SQLite. AI features are powered by MiniMax's API for Pro users. All client-side tools use the Web Crypto API, Canvas API, and other browser-native APIs — no external processing required.
For inquiries, feedback, or tool requests, reach us at hello@laiuse.com or use our support page.
LaiUse is built and operated by a small independent team of developers and designers based across Singapore and Southeast Asia. The project is self-funded and supported by non-intrusive advertising plus optional donations through Ko-fi. We respond to every support email within 48 hours and ship new tools based on user requests.
