Calm UI: An Open-Source Component Library Built for Neurodivergent Users

Design · 5 min read

Calm UI grew out of practitioner research with neurodivergent users and accessibility specialists, synthesized into a set of components that prioritize predictability and reduced sensory noise. Elements include a low-stimulus toggle for animations, collapsed progressive disclosure patterns, and forms with stepwise validation that don't interrupt typing flow.

The library ships with accessibility tokens for spacing, typography, and motion thresholds which design systems can import and override. There are also ARIA-first markup patterns and developer-focused guides explaining why each pattern reduces cognitive load, with links to the underlying research and test cases.

Early adopters in edtech and public sector projects reported better task completion rates in usability studies and fewer support tickets related to overwhelm and confusion. The maintainers encourage system designers to treat Calm UI as a design-system module to be combined with brand styling rather than a rigid UI kit.
