Why upgrade now?

Use Free Explorer to sample. Use Premium when the interview clock is running.

If you are just browsing, stay free. If you have interviews coming up, Premium reduces hunting and setup time so more of your session becomes practice.

More targeted reps

Premium unlocks deeper coding and system-design prompts when you need more than warm-ups.

Less setup time

Use the browser workflow to code, preview, test, and review instead of assembling practice from scattered tabs.

Keep sprint momentum

Save progress, return to the next prompt, and keep your prep loop moving across sessions.

Risk reversal

Try the free workflow before you decide

Refund requests are reviewed case by case within applicable legal windows and generally require limited Premium usage. Renewal charges and unused subscription time are generally non-refundable; mandatory consumer rights still apply.

Free Explorer

Not ready to pay? Run a free challenge first

  • Open a free challenge and run tests or preview before upgrading.
  • Browse the free library and premium previews to judge fit.
  • No card required until you choose a Premium plan.

Free vs Premium

Use Premium for focused depth; keep Free Explorer for sampling and warm-ups.

FAQ

Getting Started

FrontendAtlas is built to make you interview-ready faster by turning prep into repeatable practice loops.

What you do here:
- Solve realistic coding tasks with starter code + fast feedback (preview/tests)
- Learn core concepts in a way you can actually explain in interviews
- Practice front-end system design by making tradeoffs, not memorizing buzzwords

If you want “less reading, more doing” — this is the workflow.

It’s all in the browser — no setup tax.

Open the app → pick a task → code immediately.
No local project, no dependency hell, no “works on my machine”.

Desktop/laptop is recommended so you can use the editor/preview layout efficiently.

Best experience on modern desktop browsers:
- Chrome / Edge (top pick for speed + compatibility)
- Safari
- Firefox

Mobile/tablet works for reading and browsing, but serious practice is designed for desktop (editor + preview + checks).

Content & Learning

You’ll practice the three things interviews actually test:

1) Coding tasks
Build/modify real UI and logic with starter code, then validate with preview/tests.

2) Concept questions
Short prompts that force clean mental models (the kind you can explain under pressure).

3) Front-end system design
Architecture prompts focused on constraints + tradeoffs (how seniors think).

Coverage is designed to match real job requirements:
- JavaScript / TypeScript fundamentals (async, closures, DOM, performance, etc.)
- HTML / CSS (layout, responsive UI, practical accessibility basics)
- React / Angular / Vue (component patterns, state, rendering, performance)
- Front-End System Design track (architecture and tradeoffs)

So you can prep for “framework interview” and “real-world frontend” at the same time.

Everything is structured to reduce decision fatigue and keep you consistent.

You can filter/sort by:
- Technology (JS/TS, HTML/CSS, React, Angular, Vue, System Design)
- Difficulty (ramp up without getting stuck or bored)
- Tags (the exact skill being tested: event delegation, memoization, layout, state, etc.)

This makes it easy to build a weekly plan: pick a focus → grind a tight set → level up.

Yes — supported question sets include solutions and detailed explanations.

Included solutions focus on what matters in interviews:
- a clean baseline implementation
- edge cases + common mistakes
- tradeoffs between approaches (when it’s not just “one right answer”)

Some prompts are intentionally open-ended to mirror real interview discussion.

Coding Experience

Yes — many tasks have live preview so you can iterate fast and see what you’re building immediately.

This is ideal for HTML/CSS and UI work where “correct” is visual.

If preview isn’t the right signal (pure logic), the task uses checks/tests instead — so you still get clear pass/fail feedback.

Yes — tasks that can be validated deterministically include checks/tests (common for JS/TS).

This helps you practice like a professional workflow:
write → run checks → fix edge cases → ship.

HTML/CSS tasks typically rely on live preview first, because visuals are the primary correctness signal.

Yes — your work is saved locally in your browser so you don’t lose progress mid-practice.

Why this matters:
- You can do short sessions (even 15–30 min) and continue later
- Your drafts stay private on your device by default

You can also reset any task back to the starter whenever you want to re-practice from scratch.

Plans & Billing

Premium is for people who want the fastest path to results.

Typically, it unlocks:
- Premium question sets and deeper practice content
- Guided solutions and explanations across supported question sets
- Ongoing content updates while your plan is active

If you’re practicing consistently, Premium mainly saves you time: less hunting, more reps.

Yes.

Cancel anytime and you keep access until the end of your current billing period.
No “gotchas” — you’re just stopping the next renewal.

We handle refunds fairly and consistently, based on the rules in our Refund Policy.

Eligibility depends on factors like purchase type and usage.

For the exact terms, see /legal/refund.
If you think you were charged incorrectly or something isn’t working, email support@frontendatlas.com and we’ll help.

Support

Email support@frontendatlas.com with:
- steps to reproduce (what you clicked / expected / got)
- browser + OS version
- the page URL or question id

A screenshot or short screen recording speeds up fixes a lot.

Quick checklist (most issues are one of these):

- Re-check billing details (name, address, ZIP/postal code if required)
- Try a different card (or a virtual card)
- Disable VPN/ad blockers that can break checkout flows
- Make sure your bank allows online/international payments

If it still fails: email support@frontendatlas.com with the time of the attempt + your account email.
