Glass morphism hit its peak in UI design around 2021 with iOS 15 and a wave of Dribbble shots. By 2023, designers were calling it overused. In 2025, it is still everywhere in motion design — and for good reason.
Why Glass Morphism Works in Motion
Static glass morphism can look like a trend. Animated glass morphism is a different thing entirely.
When a glass panel slides in, catches light, and reveals a frosted blur of what is behind it — that is not a trend. That is a visual metaphor for transparency, layering, and depth. These are concepts that tech brands genuinely want to communicate.
SaaS companies use glass animations because they imply:
- Sophisticated interface design — the product looks premium
- Depth and dimensionality — the interface has layers, it is not flat
- Modern technology — glass morphism reads as "Apple-level" polish
Where It Fits and Where It Doesn't
Glass morphism works when it has something to be transparent over. The effect depends entirely on having a rich, colourful, or detailed background for the glass to blur and distort.
Good contexts:
- SaaS product demo animations with gradient or abstract backgrounds
- App UI mockup animations
- Dashboard and data visualisation presentations
- Tech brand content with dark, rich backgrounds
Bad contexts:
- White or very light backgrounds (the glass effect disappears)
- Minimalist brands that rely on negative space
- Content where the viewer needs to focus on what is behind the glass
The Technical Reality
A convincing glass effect in After Effects is a multi-layer system — blur, displacement, rim light, highlight, glow. When done properly, it catches light differently depending on the background, has subtle depth, and animates naturally.
Done poorly, it is just a blurred rectangle with low opacity. The difference between the two is in the details: the displacement that simulates optical distortion, the rim light that creates edge depth, the subtle gradient in the panel body.
The Liquid Glass Script for After Effects automates all of this — the full 4-layer system is built and linked in one click. For more complex glass UI panels with 7 layers (displacement, glow, rim light, outline), the SaaS Panel Kit handles the entire rig automatically.
Glass Morphism vs Flat UI in Motion
The practical answer in 2025: use glass morphism when you want to signal premium. Use flat design when you want to signal clarity and focus.
Most successful SaaS demo animations combine both — flat UI for the functional interface elements (buttons, inputs, text), and glass panels for the containers and hero elements. The glass provides visual richness; the flat UI provides readability.
What Comes After Glass?
Motion design trends move in cycles. What is clear is that dimensional, physically-inspired effects are not going away — they are getting more sophisticated. The next evolution is likely real-time 3D integration in compositing tools, where glass effects respond to actual light sources rather than simulated ones.
For now, glass morphism done well remains one of the most effective ways to make motion design look expensive.
