Jank & jumps
Scrollbars slip out of sync, rows jump as heights change, and “infinite” lists suddenly snap when new data arrives.
Next-Generation Virtualization Engine
Cerious-Scroll is the next evolution of virtualization.
A patent-pending virtualization engine designed for data-heavy web applications. O(1) memory, pixel-perfect dynamic heights, and GPU-stable performance at tens of millions of rows. Framework-agnostic and ready for your stack.

The Problem
Traditional virtual scrolling breaks at scale.
Legacy engines were never designed for unbounded datasets, dynamic heights, and real-time updates. As data size grows, so do scroll glitches, memory spikes, and user frustration.
Memory that explodes
Virtualization layers that allocate per row or per region, leading to 100s of MB used long before you hit real-world scale.
Dynamic heights? No thanks.
Many engines simply can't handle dynamic content heights, or do so at the cost of stability and accuracy.
The Cerious-Scroll Engine
A new approach to virtual space.
Cerious-Scroll uses a compact, engine-first model for representing large virtualized surfaces. The result is O(1) memory usage, pixel-perfect accuracy, and stability under extreme load — without tying you to any specific UI framework.
O(1) memory footprint
Pixel-accurate height handling
Optimized windowing model
Real-time reconciliation
Sub-frame scroll handling
Framework-agnostic integration
Benchmarks
Stable at millions of rows. Measured, not imagined.
In real-world, browser-based tests, Cerious-Scroll sustains high frame rates and low memory usage even at extreme row counts.
Conventional virtual scrolling
A leading grid vendor's stock virtual scrolling behavior with dynamic row heights and live updates enabled.

Integrations
Works with your UI stack.
Cerious-Scroll is engine-first and framework agnostic. Integrate it into existing grids and components, or build new experiences directly on top of the virtualization layer in the framework of your choice.

About Cerious DevTech
The lab behind Cerious-Scroll.
Cerious DevTech is a small, focused engineering studio obsessed with solving the hard problems at the edge of front-end performance. Cerious-Scroll emerged from years of building real-world data grids where "infinite scrolling" was more marketing term than reality.
We don't build yet another grid. We build the virtualization engine that makes every grid better.
