Segment Builder

Describe an audience in a few rules and watch it form: the head count rolls, the size bar slides, and real people from your sample glide in and out of the list as each rule tightens or loosens.

Install

Run this in any project set up for the shadcn CLI. It copies the Segment Builder source into your components folder, so the code is yours to change.

npx shadcn@latest add https://devl.dev/r/segment-builder.json

Use it

Import it and render it. Every prop has a typed default, so it works straight away, and you pass your own data when you’re ready.

import { SegmentBuilder } from "@/components/segment-builder";

export default function Page() {
  return <SegmentBuilder />;
}

Alert Rules

An alert you write as a sentence: when error rate is above 2% for at least 5 minutes, only for checkout in production, page the on-call. A 30-day timeline shows which past incidents it would have caught, and warns you before it gets noisy.

Filter Bar

Linear-style filter chips you build from one menu: Status is not Done, Labels include Bug, Assignee is me. Click any part of a chip to change it, press F to add one, Backspace to drop it, and the issue list re-sorts itself as you go.

Flag Playground

Paste a user as JSON and watch every flag decide, rule by rule: each condition ticks or crosses, the winning rule lights up, later ones grey out, and the served variant swaps in. Broken JSON and wrong types get called out instead of quietly failing.

Flag Targeting

Targeting rules for a feature flag, per environment: if beta and in Europe serve the new checkout, roll out to 10% of everyone else, fall back when it's off, and see who gets what across 2,000 simulated users while you edit.
