Picking the right tools early can save you weeks of rework later. What you need depends on where you are in the process, how big your team is, and how complex the product is getting.

Figma is where most teams do their UI/UX work now, and for good reason. It runs in the browser, so the whole product team can work in the same file at the same time. Its component system, auto-layout, and design token support are genuinely useful when you're building dashboards that need to stay consistent across dozens of views. The prototyping tools are good enough to run real user tests before anyone touches code.

Sketch still has a place, mainly on Mac-only teams. It's lost some ground on collaboration, but its plugin ecosystem keeps it workable for plenty of teams.

On the development side, charting libraries do the heavy lifting. Recharts and Chart.js are the easiest to get started with. D3.js gives you more control but asks a lot more from your developers. Highcharts is a solid commercial option if you need enterprise-grade features out of the box. All of them integrate well with React, Vue, or Angular.

For user testing, Maze, Useberry, and Lookback all connect directly to Figma, so you can get feedback on a prototype without building anything real first. Worth doing earlier than most teams think.

Storybook is where your component library lives once the product is mature enough to have one. It documents your reusable UI components and keeps everyone, designers and developers alike, working from the same source of truth.

Once the dashboard is live, Hotjar and FullStory show you how people actually use it. Heatmaps and session recordings have a way of humbling even the most confident design decisions, and they're often where the most useful redesign ideas come from.
