UX design is one of the most in-demand skills in the tech industry, but most UX designers are employed full-time and leave significant income on the table. Companies that can't hire full-time UX designers — startups, agencies, small SaaS companies — have real budgets for contract and project work.
Here are the best side hustles for UX designers, with real income numbers and how to start.
1. Freelance UX/UI Design Projects
The most direct path. Companies constantly need UX work that doesn't justify a full-time hire: mobile app redesigns, onboarding flow improvements, feature design for a specific product area.
Realistic income: $75–$200/hour. Project-based work runs $2,000–$15,000+ depending on scope. A mobile app UX audit and redesign (30–40 hours) can earn $4,000–$8,000.
How to start:
- Build a portfolio that shows process, not just screenshots. Clients want to see how you think: research, wireframes, testing, iteration. Final screens without context don't close projects.
- List on Toptal, Upwork, or Dribbble for hire. Toptal has the highest rates ($100–$200/hour) but a selective vetting process. Upwork has higher volume.
- Start with companies in your professional network before cold outreach. Former colleagues at other companies, companies in your industry, and founders you know on LinkedIn are your warmest leads.
- Scope projects carefully. "UX review and redesign of checkout flow" with a defined deliverable closes faster than "help with UX."
What pays the most per hour: Mobile app design for SaaS or fintech companies. These teams have budget and real deadlines.
2. UX Audits and Design Reviews
A UX audit is a structured review of an existing product that identifies usability issues, friction points, and improvement opportunities. Most product teams can't do this objectively for their own product.
Realistic income: $500–$2,500 for a small product audit. Comprehensive audits for enterprise products run $3,000–$10,000.
How to start:
- Define a clear deliverable: a written report with annotated screenshots, heuristic evaluation scores, and prioritized recommendations.
- Create a fixed-price offer: "UX audit of your mobile app or web app — $1,200 for a 48-page report delivered in 5 business days."
- Market to SaaS companies with churning users. They often know their product has usability problems but don't have the bandwidth to audit it systematically.
- Cold email works here: find companies with sub-3-star App Store ratings. "I reviewed your iOS app and found 7 specific friction points causing abandonment — here are the first two" is a compelling opener.
Why this works: Audits have a defined scope and timeline. You're not signing up for an open-ended relationship — just a focused engagement with a clear output.
3. Design System Consulting
Companies that have built products haphazardly often have inconsistent design languages: different button styles across screens, inconsistent spacing, mismatched typography. Cleaning this up requires a design system specialist.
Realistic income: $100–$175/hour. Design system projects typically run 2–4 weeks and earn $5,000–$20,000.
Who needs this:
- Pre-IPO startups trying to bring design consistency before scaling
- Companies that acquired another product and need to unify the UI
- Engineering teams building component libraries who need design input on the spec
- Companies migrating to a new front-end framework who need a systematic design audit
How to start:
- Specialize in the tools you know: Figma is the dominant platform. If you can build a design system in Figma with component libraries, tokens, and documentation, that's the deliverable.
- Look for companies that have recently raised a Series A or B. This is when design consistency becomes a real pain point as the team scales.
- Your pitch: "I help scaling companies bring consistency to their product UI so engineering can ship faster and QA can catch regressions more easily."
4. User Research as a Service
UX researchers are rarer than UX designers. If you have research chops — interview facilitation, survey design, usability testing — companies will pay specifically for research, not just design.
Realistic income: $100–$200/hour for research projects. A usability study (5–8 participant sessions + analysis report) runs $3,000–$8,000.
What companies commission:
- Moderated usability testing on a new feature before launch
- Jobs-to-be-done research to understand what users are really trying to accomplish
- Competitive analysis and benchmarking research
- Continuous discovery support (ongoing interview cadence + synthesis)
How to start:
- Separate your research offer from your design offer. "User research specialist" is a distinct market position from "UX designer."
- List on User Interviews — they have a marketplace for research participants and freelance researchers.
- Offer a starter package: 5 user interviews + synthesis report + 3 key insights. $1,500–$2,500 for a week of work. Easy for companies to buy.
5. Teaching UX Design
The demand for UX education is enormous — bootcamp graduates, career changers, junior designers trying to level up, product managers learning UX. You can teach all of them.
Realistic income: $40–$80/hour for coaching and mentorship. Online courses on Skillshare or Udemy earn $500–$3,000/month passively for established instructors.
How to start:
- Mentor through ADPList (free mentoring platform that builds your reputation and leads to paid opportunities) or Through the Design League.
- Offer paid portfolio reviews: 60-minute session to review a junior designer's portfolio with actionable feedback. $100–$200/session. High demand from bootcamp graduates entering the job market.
- Build a course on a specific UX topic: "UX Portfolios That Get Interviews," "Conducting User Research Without a Budget," or "Design Systems in Figma from Scratch."
What makes this scale: A recorded portfolio review course with 5+ hours of content can passively earn $300–$1,500/month on Skillshare while you work your day job.
6. Product Design Consulting for Startups
Seed-stage startups often have founders who can wire up an MVP but need product design help before raising a Series A. They can't afford a full-time designer but can budget $3,000–$8,000 for a focused engagement.
Realistic income: $4,000–$15,000 for a startup design project. Equity compensation is possible but don't count on it to pay rent.
What this looks like:
- MVP UX/UI design from wireframes to handoff (3–6 weeks)
- Investor pitch deck product screens (2–3 days, $1,000–$2,500)
- App redesign before a fundraising round (4–6 weeks)
- Onboarding flow optimization with A/B testing setup
How to start:
- Network in startup communities: AngelList, local co-working spaces, startup Slack communities.
- Offer a product review call for free ("I'll spend 30 minutes reviewing your product and tell you what's hurting your conversion"). Get in the door, then scope a paid project.
- Build relationships with startup incubators and accelerators (Y Combinator, Techstars) — they often connect their companies with freelancers.
7. Selling Figma Templates and UI Kits
Designers buy Figma components, design system templates, and UI kits constantly. If you build well-structured assets, they sell indefinitely.
Realistic income: $10–$100 per template. Established sellers on Gumroad, UI8, or Creative Market earn $500–$5,000/month.
What sells well:
- Mobile UI kits (iOS/Android design patterns)
- Dashboard design templates for SaaS
- Design system starter kits with components and tokens
- UX research templates (interview guides, affinity mapping, journey map templates)
- Portfolio case study Figma templates
How to start:
- Build something you've needed yourself — a component library, a wireframe kit, a handoff template. If you needed it, other designers do too.
- Sell on Gumroad, UI8, or Creative Market. All three have designer audiences who buy templates.
- Price mid-range: $29–$79 for a quality kit. Cheap templates ($5–$10) signal low quality; expensive templates ($150+) require significant brand trust.
How to Find Your Best Side Hustle
Your path depends on your specialty and time availability:
- Strong in visual design? Freelance projects or Figma template sales.
- Have research skills? User research as a service.
- Experienced with systems? Design system consulting.
- Want passive income? Courses or template sales.

Mistakes UX Designers Make Starting Side Work
A portfolio without process. Showing only final screens is the fastest way to not get hired. Clients pay for thinking — show your research, your wireframes, your decision rationale.
Underpricing based on design platforms' suggested rates. Upwork's "Intermediate" range for UX is $40/hour. Experienced UX designers in the market get $100–$175/hour. Know your market rate.
Taking on too-broad projects. "Help us redesign our whole product" with no defined scope is how projects become 3x the original estimate with no additional pay. Scope rigorously.
Not separating research from design. If you have research skills, sell them separately. Research-only engagements often pay more per hour than design work.
