If you're new to UI/UX design, you've probably seen endless tool lists without any explanation of what they actually do or when you'll need them. Here's the truth: tools exist to solve specific problems like wireframing interfaces, testing with real users, or handing work off to developers. This guide covers ten tools you'll encounter in your first junior role. You don't need to master them all immediately. You need to recognize what each one handles, open the files without panicking, and follow along when senior designers reference them in meetings. Understanding the basics prevents you from slowing down your team, misinterpreting feedback, or designing in ways that create problems downstream.

1. Figma

Figma is where most interface design happens now. You'll use it to arrange UI elements, apply colors and typography, build reusable component libraries, and create clickable prototypes that simulate how an app or website actually works. Junior designers spend significant time inside Figma because it handles the full spectrum from rough wireframes to polished mockups. If you can't navigate layers, understand how frames and components work, or follow version history, you'll struggle to interpret design files that senior designers hand you or collaborate without accidentally breaking shared components. Teams organize entire workflows here, so literacy with Figma's core features determines whether you contribute smoothly or constantly need help with basic tasks.

2. FigJam

FigJam handles the messy early stages before anyone touches Figma's design tools. You'll use it to dump sticky notes from user interviews, group observations into themes, sketch rough ideas collaboratively, and map out user journeys visually. Design doesn't start with polished screens. It starts with research synthesis, brainstorming sessions, and alignment workshops where teams make sense of problems before proposing solutions. Junior designers who skip FigJam literacy miss critical context about why design decisions were made, struggle to contribute during discovery phases, and can't organize research findings in ways that teams actually reference later. Understanding FigJam means you can participate in the messy, important work that happens before pixels get pushed.

3. Miro

Miro is a digital whiteboard used for remote collaboration, design sprints, and cross-functional workshops. You'll use it when product managers, developers, and designers gather to map user flows, conduct card sorting exercises, run retrospectives, or align on product strategy. Junior designers participate in these sessions constantly, and Miro is where teams think together visually. If you can't add content to shared boards, follow structured workshop templates, or connect ideas spatially, you'll sit silently during critical planning meetings while everyone else shapes direction. Missing Miro literacy means missing the conversations where big decisions get made, not just documented.

4. User Research Platforms

Tools like UserTesting, Maze, and Lookback let you watch real people use your designs and collect their feedback without flying to five cities for in-person sessions. You'll use these platforms to set up usability tests, review session recordings, analyze task completion rates, and identify navigation problems that never surfaced in internal reviews. Junior designers absolutely must learn to validate design assumptions through testing, not opinions. If you can't set up a basic unmoderated test, interpret heatmaps, or watch recordings without getting defensive, you'll design based on guesses and personal preferences, which leads to interfaces that confuse actual users and require expensive fixes after launch.

5. Figma Dev Mode

Dev Mode lives inside Figma but serves a completely different purpose than design work. You'll use it to prepare handoff by marking spacing values, exporting assets in the correct formats, documenting interaction states, and ensuring developers have everything they need to build what you designed. Developers cannot read mockups like designers do. They need precise measurements, color tokens, and exportable SVG icons. Junior designers who skip Dev Mode create incomplete handoffs, forcing developers to guess at spacing or hunt for assets, which delays implementation and creates inconsistencies between your designs and what users actually see. Understanding Dev Mode turns you from someone who designs pretty screens into someone who designs buildable interfaces.

6. Design System Tools

Platforms like Storybook and Zeroheight document reusable components, spacing standards, color tokens, and accessibility guidelines in one central reference library. You'll use these tools constantly to look up existing button styles before creating new ones, verify typography rules, and check which interaction patterns your team has already solved. Design systems exist because consistency matters more than individual creativity on most projects. If you can't reference documented components or follow established patterns, you'll recreate work that already exists, apply inconsistent spacing, violate brand guidelines, and create visual debt that someone has to clean up later. Knowing where to find answers prevents you from wasting time solving solved problems.

7. Accessibility Testing Tools

Plugins like Able, Stark, and browser extensions like Axe DevTools identify contrast failures, missing alt text, keyboard navigation problems, and screen reader incompatibilities before your designs reach production. You'll use these tools to check every mockup against WCAG standards, simulate color blindness, and verify that interactive elements work for people using assistive technologies. Accessibility isn't optional, and junior designers who can't run basic checks ship designs that exclude users with disabilities and expose companies to legal risk. If you don't know how to test contrast ratios, you'll hand off interfaces that fail audits and require expensive retrofits, making you the person who creates problems instead of solving them.

8. Image and Icon Libraries

Services like Unsplash, IconFinder, and Flaticon provide stock photography, vector icons, and illustrations you can use without hiring photographers or illustrators for every project. You'll use these libraries to populate mockups with realistic imagery, find scalable icons that match your design language, and avoid copyright issues on practice projects or client work. Placeholder text and gray boxes make designs impossible to evaluate. Stakeholders and users need realistic visuals to provide meaningful feedback on layout, hierarchy, and emotional tone. Without knowing where to source high-quality, license-compliant assets quickly, you'll waste hours searching or accidentally use protected imagery that creates legal problems.

9. Prototyping and Animation Tools

Tools like Principle, ProtoPie, and Adobe After Effects handle complex interactions, micro-animations, and motion design beyond what Figma's native prototyping can demonstrate. You'll use these when designs require gesture-based interactions, conditional logic, precise timing, or animations that stakeholders and developers need to see in motion before committing to implementation. Some design decisions only make sense when users experience them dynamically. Static mockups can't communicate how elements respond to scrolling, how transitions create continuity between screens, or how micro-interactions provide feedback. If you can't prototype nuanced interactions, you'll struggle to communicate sophisticated interaction patterns clearly, leading to misunderstandings during development.

10. Collaboration and Handoff Tools

Platforms like Zeplin, Abstract, and Notion centralize design documentation, version control, and cross-functional communication in shared spaces that everyone can reference. You'll use these tools to annotate designs with context, track file revisions without overwriting teammates' work, document design decisions that developers and product managers need to understand, and maintain single sources of truth when projects involve multiple contributors. Design doesn't happen in isolation. Teams need shared infrastructure to discuss rationale, resolve version conflicts, and ensure alignment across functions. Without basic competence in collaboration tools, you'll lose feedback, duplicate effort, or hand off outdated files that waste everyone's time.

Summary

• These ten tools collectively enable you to research user needs, design functional interfaces, validate assumptions through testing, prepare specifications developers can build from, ensure accessibility compliance, and collaborate across teams.
• Focus on recognizing when each tool applies and navigating basic workflows rather than memorizing every feature across all platforms simultaneously.
• Tool literacy prevents common mistakes like designing without validation, handing off incomplete specs, violating accessibility standards, or recreating components that already exist in your design system.
• Tools make collaboration possible, ensure legal compliance, and translate ideas into buildable interfaces, but they never replace critical thinking, user empathy, or sound design judgment.

FAQ

Do beginners need to master all these tools? No. You need baseline familiarity, which means you can open files, navigate interfaces, and understand what problem each tool solves. Mastery develops through repeated use in actual projects, not upfront study. Start with whichever tools your current work requires, then expand literacy as workflows demand. Many tools overlap in functionality, so recognizing when Figma handles a task versus when you need specialized platforms matters more than memorizing features.

Are these tools used the same way at every company? No. Companies customize workflows, build internal templates, and sometimes use completely different tools for identical tasks. One team might prototype entirely in Figma while another requires ProtoPie for animations. Tool names and interfaces stay consistent, but file organization, naming conventions, and handoff processes vary widely. Ask how your specific team uses each tool rather than assuming universal standards, and adapt your knowledge to local practices.

Can one tool replace another on this list? Sometimes. Figma handles wireframing, prototyping, and basic collaboration, potentially replacing Miro or dedicated prototyping tools for straightforward projects. However, specialized platforms like accessibility checkers solve problems Figma cannot address alone. Learn what tasks Figma's native features already handle versus when you genuinely need dedicated tools. The goal is avoiding unnecessary complexity while recognizing when specialized platforms deliver meaningfully better results for specific problems.

How do beginners practice using these tools safely? Create personal practice projects using fictional companies and dummy data to build familiarity without risking real client work. Most tools offer free starter plans or education licenses. Follow publicly available tutorials, replicate existing designs to understand mechanics, and join design communities where experienced practitioners share templates and workflows. Never practice on live company files until you understand version control, file permissions, and how your specific team handles handoffs and approvals.
