What Frontend Mentor is

Frontend Mentor is a web service for building front-end skills through realistic challenges based on professional designs. Its library offers more than 120 projects at five difficulty levels, and learners can complete them with any technology stack. The challenges support practice and portfolio building, with programming content covering HTML, CSS and JavaScript. Every submission gets automated checks for accessibility, HTML, CSS and JavaScript. AI code reviews assess work across seven dimensions and link findings to specific code lines. The Free plan includes free design challenges, one AI code review each month and two AI-enhanced reports each month. Those free design challenges come with JPEG images and a style guide. Pro adds Figma files containing design system details and tablet layouts; product challenges also provide specifications, a brand kit, UI/UX guidance, sample data, starter CSS and AI context files. Submissions are made with a repository URL, which Frontend Mentor uses to create reports. GitHub is currently the only sign-up method, and signing up does not grant repository access. Learners can seek challenge help on Discord, where members can review each other’s code. Subscriptions renew automatically and can be managed in Settings; a fair-use refund policy applies within 14 days of a first subscription.
