I just wanted to share a few tools that I use daily for my work.
1. Penpot
An open-source, browser-based UI/UX design and prototyping tool. Ideal if you want a non-mainstream, collaborative alternative to Figma or Sketch.

2. Animista
A niche CSS animation playground offering ready-to-use animations you can customize and export. Great for micro-interactions without writing animations from scratch.

3. Origami Studio
A powerful prototyping tool created by Facebook. Excellent for high-fidelity interactions and motion design; especially useful for experimenting with non-standard UI behavior.

4. MockFlow
A lightweight wireframing and site-structure planning tool. Perfect for brainstorming, quick layout sketches, and creating project architecture without heavy design suites.
