## What it is
Omatsuri is a progressive web application bundling 12 open-source frontend-focused tools such as CSS generators, SVG compression/conversion, and fake data generation. It runs entirely in the browser with offline support, web workers, and no tracking or server connections.

## Use cases
- generate css triangles, gradients, and color shades
- compress svg files and convert svg to jsx
- encode strings to base64 in the browser
- generate realistic fake data for testing
- look up javascript event keycodes
- generate lorem ipsum placeholder text
- find css cursor property values
- use frontend utilities offline without ads or tracking

## When to choose
- you need quick everyday frontend utilities in one place
- you want privacy-respecting tools that run fully offline in the browser
- you need to compress or convert SVGs without uploading files to a server
- you want to generate fake data or placeholder text for development

## When to avoid
- you need backend, build, or CI tooling rather than browser-based utilities
- you require advanced or highly specialized design tools beyond the 12 included apps
- you need team collaboration or cloud-synced features
