PracHub Alternatives (2026): Free DSA & System Design Prep
The best PracHub alternatives in 2026 are InterviewSkool, LeetCode, NeetCode, and AlgoExpert. If you want the exact company-tagged problems PracHub markets but without paying for solutions, InterviewSkool is the strongest free option: 433 company-tagged DSA problems with full solutions, hints, and diagrams, plus 369 system design questions across 31 companies — nothing locked behind a paywall.
PracHub (prachub.com) built its reputation on a database of 11,000+ real interview questions with company, role, category, difficulty, and round filters. What most candidates don't realize until they dig in: the full solution walkthroughs, model solutions, and AI Mentor sessions sit behind a Premium subscription. This guide compares the top PracHub alternatives for 2026 and tells you exactly what each one costs — including the completely free option.
What PracHub Offers (and What It Locks)
PracHub's free tier lets you browse questions, read community discussions, and use the in-browser coding console. The paid Premium tier unlocks:
- Full solution walkthroughs on locked questions
- Model solutions in the coding console
- AI Mentor sessions
- Video explanations and structured learning tracks
The core value most candidates want — a clear walkthrough of how to solve a problem — is exactly what PracHub gates. Every alternative below solves that gap differently.
Top PracHub Alternatives (2026)
1. InterviewSkool — Best Free PracHub Alternative
Best for: Candidates who want PracHub-style company-tagged problems, solutions, and diagrams at zero cost.
InterviewSkool is the closest free match to PracHub's core value. Its practice library is entirely free — no subscription, no per-feature unlocks.
The free problem library:
- 433 company-tagged DSA problems — each tagged with the companies that ask it (Google, Meta, Amazon, Apple, Microsoft, and more)
- Difficulty split that mirrors real loops: 81 Easy, 267 Medium, 87 Hard
- Step-by-step solution walkthroughs with worked examples and complexity analysis
- Progressive hints that simulate an interviewer guiding you
- Solution code in Python, C++, and Java — model answers in three languages
- Hand-drawn SVG diagrams visualizing arrays, trees, grids, and pointers
- Related problems with the reason each one matters
The free system design library:
- 369 company-specific system design questions compiled from 569 real interview reports
- 31 companies covered with question tags, report counts, and last-reported dates
- 17 full case-study breakdowns including make-my-trip, instagram, netflix-streaming, google-drive, and more
- Architecture diagrams (mermaid-based), scale estimates, and trade-off analyses
- 333 High-Level Design and 36 Low-Level Design questions
Price: $0 for the entire practice library. InterviewSkool earns revenue from paid AI mock interviews (live sessions with an AI interviewer named Alex that include coding, system design, and behavioral rounds with a whiteboard, 12-dimension feedback, and a hiring signal), so the problem-solving content never needs monetizing.
Limitations:
- No video lessons (text-based walkthroughs instead)
- 11,000+ raw questions? No — 433 DSA + 369 SD, focused and curated rather than mass-volume
- No community forum
Rating: 9.2/10
Start here: Practice 433 company-tagged DSA problems and work through the system design case studies.
Company Coverage: Which Companies Are Tagged?
The company tags are what make InterviewSkool a genuine PracHub alternative — not just "some problems," but the specific problems each company asks. Here's the exact coverage across the free library:
DSA Company Tags (32 companies)
Every DSA problem carries the list of companies that ask it. Filter the DSA problems tracker by any company:
- FAANG + Big Tech: Google, Meta, Amazon, Apple, Microsoft, Netflix
- Trading & Finance: Goldman Sachs, JPMorgan, Bloomberg, Capital One, DE Shaw, Visa
- Cloud, AI & Data: OpenAI, Anthropic, NVIDIA, Databricks, Snowflake, Salesforce, Oracle
- Growth & Product: Uber, Airbnb, Pinterest, Roblox, TikTok, LinkedIn, Atlassian, Adobe, Walmart, Flipkart, Anduril, Rippling, Ripple
So for "which Google DSA problems should I solve?" the answer is filterable in one click — the same query PracHub charges Premium for.
System Design Company Pages (31 companies)
Every company has a dedicated page title "Company System Design Interview Questions" with its own problem list, report counts, and solution links — for example:
- Google System Design Interview Questions
- Meta System Design Interview Questions
- Amazon System Design Interview Questions
- Apple System Design Interview Questions
- Microsoft System Design Interview Questions
- Netflix System Design Interview Questions
Plus Uber, OpenAI, TikTok, LinkedIn, Airbnb, Oracle, Goldman Sachs, and more — 31 in total.
17 Free Case Study Breakdowns
Each case study is a complete system design walkthrough with architecture diagrams, scale estimates, and trade-offs:
make-my-trip, messenger-app, book-my-show, uber-design, coupon-generator, gaming-leaderboard, google-drive, instagram, live-streaming, netflix-streaming, push-notification, search-engine, shazam, travel-booking-platform, web-crawler, whatsapp-live-location, snap-map.
2. LeetCode — Best for Raw Problem Volume
Best for: Candidates who want the largest possible DSA database (free tier + subscription).
LeetCode is the default coding practice platform. Its free tier includes a large problem set (700+ free problems), and the paid tier (~$35/month) unlocks 3,000+ total with company-tagged questions and a better editor experience.
What it does:
- 700+ free problems (3,000+ with Pro)
- Company tags on Pro tier
- In-browser code editor and test runner
- Discussion forum for every problem
- Weekly contests
Price: Free tier (limited) | Pro ~$35/month / $159/year
Why it's a strong alternative:
You can't beat LeetCode for raw problem volume. If your prep is "grind as many problems as possible," LeetCode's free tier gives you a large, well-verified library.
Limitations:
- No solution walkthroughs (user-submitted, quality varies)
- No progressive hints designed like an interviewer
- Company tags hidden behind Pro
- No system design material
- No hand-drawn diagrams for visual learners
Rating: 7.5/10
3. NeetCode — Best for Structured Learning Paths
Best for: Candidates overwhelmed by LeetCode's huge library who want a curated path.
NeetCode takes the essential problems and organizes them by pattern — arrays, trees, graphs, DP — into a NeetCode 150 course. It's LeetCode with structure.
What it does:
- 150 curated essential problems (NeetCode 150)
- Video explanations for each problem
- Pattern-based organization
- Progress tracking
- Uses LeetCode's problems (no unique content)
Price: Free (uses LeetCode) | NeetCode Pro: $35/month
Why it's a strong alternative:
If PracHub's 11,000+ questions paralyze you, NeetCode's 150 curated problems give a clear starting point with video explanations.
Limitations:
- Still just problem-solving — no interview simulation
- No company tags
- No system design content
- Requires a LeetCode account for the actual problems
Rating: 7.0/10
4. AlgoExpert — Best for Curated Practice With Quality Explanations
Best for: Candidates willing to pay once for polished video walkthroughs.
AlgoExpert offers 167 hand-picked problems with professional video solutions from industry engineers. Quality over quantity, with a structured learning system.
What it does:
- 167 curated coding problems
- Video solutions from experienced engineers
- Code execution environment
- Complexity analysis on every solution
- One-time payment (no subscription)
Price: ~$90 one-time ($134 with SystemsExpert bundle)
Why it's a strong alternative:
AlgoExpert solves PracHub's core complaint — gated walkthroughs — with a single upfront fee and unlimited video explanations. Every problem has a clear, professional breakdown.
Limitations:
- Small problem set (167 vs PracHub's thousands)
- No company tags
- No system design (separate SystemsExpert add-on)
- No free tier for solutions
Rating: 7.8/10
