# Xicae Web Tools & Developer API

> Everyday web applications and deterministic developer utilities for astronomy, media optimization, code editing, documents, drawing, and computational APIs.

## Web Applications

- [Miqat](https://xicae.dev/miqat.md): Accurate daily prayer times for your city, real-time 3D Kaaba compass, and Islamic calendar. Clean, peaceful, and works anywhere.
- [Compress](https://xicae.dev/compress.md): Shrink heavy videos, photos, and PDFs by up to 85% in seconds without losing visual quality. Fast, sharp, and easy to use.
- [WebCode](https://xicae.dev/webcode.md): A distraction-free code editor with a phone-friendly keyboard. Write, test, and run code anywhere without installing anything.
