Flag Board

Feature flags per environment: flip a flag, drag its rollout and see how many people that is, target segments with chips, and a kill switch you have to press and hold, with undo, before it turns everything off.

Install

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

npx shadcn@latest add https://devl.dev/r/flag-board.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 { FlagBoard } from "@/components/flag-board";

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

Branch Graph

A git log drawn as a graph: each branch gets its own coloured lane, merges sweep in on smooth curves, refs and tags sit on their commits, and hovering a row slides a detail card along with you.

Code Block

A code viewer with file tabs, hand-rolled syntax colour, click-to-highlight lines, a diff view that works out the +/− itself, wrap and copy, and long files that fold behind a fade.

Cron Builder

Edit a cron expression field by field or with friendly controls, read it back as a plain sentence, see the next five runs in your timezone update as you type, and get told exactly why a schedule is invalid or can never run.

Deploy Pipeline

Install, build, test and deploy as stages that light up and connect as they pass, live timers, a log peek that follows the running stage, a failed stage you can retry in place, and the preview URL as a chip when it’s ready.
