Editorial interest 83/100 Selection signal · not a rating of the site

Quartile is an open-source React toolkit for building data apps with linked charts, editable tables, filters, and optional AI assistance.

Landing page captured for the 2026-10-23 issue.

For: React developers building analytical data applications
Worth noticing: Brushing or filtering one view can update other components through a shared selection store, without passing props between them.

Field notes

Quartile organizes 71 React components across interface, data, and chart layers, with shared theme tokens and a common data contract. Its examples include CSV/JSON exploration, cohort retention comparison, and a revenue workspace; the page also shows controls for filtering, sorting, grouping, and CSV export. The preview is source-only rather than available on npm, and its stated 128 kB JavaScript/22 kB CSS gzip figures exclude dependencies and worker assets.
