How Does Frontend Mentor Work Step by Step?

Updated

Frontend Mentor is a project-based learning platform where you build real frontend and full-stack projects from professional Figma designs and briefs, then submit your work for an AI code review and community feedback. The four-step loop is: choose a challenge, build it with any stack, submit for review, and level up to harder projects. It suits self-directed learners who already know some HTML, CSS, and JavaScript and want portfolio-ready work rather than tutorial follow-alongs; complete beginners may find the early challenges steep without supplemental instruction.

Step 1: Choose your challenge

Pick from 120+ professional projects spread across five difficulty levels. There are two project types:

  • Design-file challenges — you build to a provided Figma design, matching layout, spacing, and behavior.
  • Product challenges — you make the design decisions yourself, working from a brief rather than a pixel spec.

Start at a level where you can finish without copying a tutorial. The platform's own guidance is to hand-code the early levels to lock in fundamentals.

Step 2: Build it your way

You can use any stack: plain HTML/CSS/JavaScript, React, Node, or a full-stack setup. There is no enforced toolchain, so the challenge tests your judgment, not your ability to follow platform-specific menus.

On advanced and full-stack builds, the platform explicitly encourages practicing AI-assisted development — asking an AI questions, debugging with it, and using it to review code — framed as practice for how real teams work. The stated skill that matters is judging whether AI output is good enough to ship.

Step 3: Submit and get an AI code review

Every solution you submit can receive an AI code review with line-level findings scored against the brief's requirements. Each review feeds a skills profile that fills out as you build, so you can see which areas are strong and which need work.

Access condition: free members get one AI review per month. A review on every submission, plus the continuously updating skills profile, is a Pro feature (see the site's "Unlock Pro" page for current terms). The site markets the core learning experience as free to start; it does not state that Pro is free.

Step 4: Level up and join the community

As your skills profile grows, move to tougher challenges. You can also review other developers' code — the platform positions peer review as a way to sharpen your own reading of code and build connections. The site reports a community of over 1,202,288 developers.

What the loop looks like in practice

Stage Your input What you get back
Choose Difficulty level, design-file or product brief A scoped project with requirements
Build Any stack, hand-coded or AI-assisted A working solution
Submit Your solution Line-level AI review scored against the brief; skills profile update
Review others Feedback on peers' code Sharper code-reading skills, community ties

Is it right for you?

Good fit if: you want ready-made project ideas instead of hunting for them, you need portfolio pieces that demonstrate production-ready code, and you're comfortable learning from a brief with limited hand-holding.

Less good fit if: you need structured lessons and explanations before building, or you want unlimited AI reviews without paying — the free tier caps reviews at one per month.

A practical way to test it: pick one challenge at the lowest difficulty, build it in a stack you already know, and submit. If the review surfaces gaps you can act on, the loop is working for you.
