omatsuri

Omatsuri (お祭り, Japanese for "festival") is an open source progressive web application that gathers 12 frontend-focused utilities into a single app. The README describes it as "a small festival of applications" built with privacy in mind: there are no ads, no analytics services, and according to the README no server connections at all — the tools execute in the browser. Key features listed by the project: - Web workers for fast, non-blocking computations - No tracking, no ads, no other server connections — everything runs in the browser only - Full offline support (PWA) - Dark theme support - An all-in-one application intended for everyday tasks Included applications: - CSS Triangle Generator - Color Shades Generator - Gradient Generator - Page Dividers Generator - SVG compressor - SVG to JSX converter - Base64 encoder - Realistic Fake Data Generator - HTML/CSS Symbols Collection - Lorem/Samuel/Poke Ipsum Generator - CSS Cursor Properties - JavaScript Events Keycodes The README encourages readers to explore the source code and reuse it in their own projects. It also links to a contributing guide and a changelog for project governance and release history. Local development is documented with two commands: install dependencies with `yarn`, then start the application with `npm start`, which opens the browser automatically. No configuration files, environment variables or backend setup are described in the README; the workflow is limited to a local frontend development server. Who it is for: frontend developers and designers who need quick, browser-based helpers for CSS generation, color work, SVG optimisation, markup conversion, placeholder text and test data — without sending input to a third-party service. The offline-capable PWA format also makes it usable when a network connection is unavailable.
