SkillHacker Review (2026): Pricing, Features & Honest Verdict

TLDR

SkillHacker is a free developer interview prep tool that drills you with timed and untimed multiple-choice quizzes mapped to specific roles. It is genuinely useful for cramming conceptual knowledge, though it will not replace hands-on coding practice. Best for: developers prepping for a tech interview. Price: Free, no card required. Rating: 8.2/10.

What is SkillHacker?

SkillHacker is a browser-based interview prep platform for developers. You choose a target role, say Senior Frontend Developer, and it serves curated multiple-choice questions across the skills that role expects: JavaScript, TypeScript, React, CSS, Web APIs, system design, testing, and performance. It is not a LeetCode-style algorithm grinder where you write and run code. It is a knowledge drill that tests whether you actually know the concepts an interviewer will probe.

The product is an indie effort built by Vitaly Obolensky, a solo founder. The footer reads 2026 and there is an active blog and changelog, so development is ongoing. We found no big company or funding behind it, which is worth knowing: this is a young, single-maker tool. That brings the usual trade-offs, fast iteration on one hand, longevity and support questions on the other.

Why does a tool like this matter now? Interviews have shifted. A lot of candidates over-index on algorithm grinding and then freeze when an interviewer asks them to explain how the event loop works or why a React component re-renders. Those conceptual questions are where offers are won and lost, and they are exactly what SkillHacker drills. It fills a gap between the heavyweight coding platforms and a pile of half-remembered blog posts, and it does it in a format you can fit into short bursts of study.

What Are SkillHacker’s Key Features?

Role-based learning paths

Instead of dumping random questions at you, SkillHacker organizes everything around the role you are targeting. Pick a path and it surfaces the skill categories that matter for that job, then lets you drill each one. For a front-end role that means JavaScript, TypeScript, React, CSS, Web APIs, and system design. This focus is the feature that makes it feel less like trivia and more like targeted revision.

Timed Test mode and untimed Practice mode

SkillHacker splits practice into two modes, and this is the part it does best. Practice mode is untimed, with hints and links to documentation, so you can learn as you go. Test mode is timed and strips the safety net, simulating the pressure of a real interview where you have to answer confidently and fast. Switching between the two is the difference between studying a topic and proving you can recall it under stress.

Progress benchmarking

The tool tracks your results and lets you compare them against other users targeting the same role. That gives you a rough read on where you stand before walking into an interview, which is something a stack of flashcards cannot do. It is not a precise hiring signal, but it is a useful gut check on which topics still need work.

Offline access

SkillHacker supports offline practice, so you can revise without a connection. For anyone who crams on a train or plane before an interview, that is a small but real advantage over web tools that grind to a halt the moment your signal drops. It also nudges you toward short, frequent sessions, which is how recall actually sticks, rather than one marathon study night that you forget by morning.

One thing the blog makes clear is that the whole product is built around a single thesis: knowing the theory is not the same as answering confidently under pressure. The timer is not a gimmick, it is the mechanism that turns passive familiarity into the kind of fast, certain recall an interviewer is testing for. Whether that thesis holds for you depends on how you interview, but it is a coherent and well-argued design, and it shapes every feature in the tool.

How Much Does SkillHacker Cost?

SkillHacker is free. The site pushes a Get Started Free button and states clearly that no credit card is required. We looked for a pricing page at the usual paths and found none: there is no published paid tier, no plan comparison, and no documented free-tier limits. As far as the public site shows, you get the full product at no cost.

That makes it hard to beat on price. LeetCode Premium runs $35 a month, AlgoExpert is roughly $99 to $129 per year, and even free options like HackerRank gate some features behind employer-side plans. SkillHacker asks for nothing, which is rare for a tool this focused. The flip side is that a free indie product with no pricing model raises a fair question about long-term sustainability.

Because there are no published limits, we cannot tell you how much usage the free tier allows or whether a paid plan will appear later. If it does, the value calculation changes. For now, treat it as a free tool that costs you nothing but your time.

It is worth weighing that against what the paid alternatives buy you. LeetCode and AlgoExpert charge because they offer real code execution, large curated problem sets, and years of refined explanations. SkillHacker offers none of that depth, so the fair way to read its free price is not as a steal but as appropriate for what it is: a focused concept-drilling tool, not a full prep platform. At zero cost there is simply no risk in adding it to your routine, and that is the strongest thing you can say about its pricing.

Who is SkillHacker Best For?

Use SkillHacker if you have a developer interview coming up and want to drill the conceptual questions that get asked out loud, the JavaScript closures, the React render behavior, the system design trade-offs. It is ideal for front-end and full-stack candidates who want structured, role-specific revision for free. It is also a good warm-up before deeper coding practice.

Skip SkillHacker if you need to practice writing and running actual code, because the multiple-choice format does not test that. Skip it too if you want a proven, established platform with years of content and reviews behind it, since this is early-stage and unverified. For algorithm-heavy interviews at large tech companies, pair it with a code-execution platform rather than relying on it alone.

It also fits a particular moment in your prep. In the week before an interview, when you are trying to refresh a wide surface area of concepts quickly, SkillHacker is close to ideal. Months out, when you are building deep skills from scratch, it is less the right tool, because drilling questions tests what you know rather than teaching you new things. Think of it as a sharpening stone, not a textbook.

Best SkillHacker Alternatives

LeetCode

LeetCode is the dominant coding-interview platform, with real code execution against thousands of problems tagged by company. Premium costs $35 a month or $159 a year. It is far more rigorous than SkillHacker for algorithm prep, but it is also a different exercise: writing code, not answering concept questions. Many candidates use both, LeetCode for the coding rounds and SkillHacker for the conceptual ones.

HackerRank

HackerRank is free for individual developers, with guided challenges, language-specific skill tracks, and certifications. Its paid tiers are aimed at employers running hiring assessments, not at candidates. It overlaps with SkillHacker on the free, skill-tracking front, but leans toward hands-on challenges rather than pure multiple-choice drilling.

AlgoExpert

AlgoExpert sells a curated curriculum of around 100-plus coding questions with detailed video walkthroughs, priced at roughly $99 to $129 per year with no true monthly option. It is more structured and polished than SkillHacker, but it costs money and focuses on coding rather than the conceptual recall SkillHacker drills.

Final Verdict: Is SkillHacker Worth It?

SkillHacker earns its place as a free, focused interview prep tool. The role-based paths keep your revision targeted, and the split between a timed Test mode and an untimed Practice mode is the right design for building genuine recall instead of passive familiarity. For the price, which is nothing, it is hard to argue against trying it before your next interview.

The caveats are honest ones: it is a young solo product with no track record, no published pricing, and a multiple-choice format that cannot test real coding ability. Use it as part of your prep, not all of it. Pair it with a code-execution platform like LeetCode for the hands-on rounds, and lean on SkillHacker for the conceptual questions. As a free supplement, we recommend it.

Our rating reflects that balance. The execution is sharp, the role-based focus is genuinely useful, and the timed mode is the right idea for building interview-ready recall, which is why it lands high. We held back from the very top of the scale only because it is unproven and narrow in what it can test. If you have an interview on the horizon, spend an evening with it. The downside is nothing and the upside is walking in able to answer the conceptual questions without hesitating.
