# The best HackerRank alternatives in 2026 > Facts last reviewed: August to October 2026. Canonical page: https://kendor.io/alternatives/hackerrank The best HackerRank alternative depends on why you are leaving. If you want candidates on real project work instead of puzzles, Kendor runs job-shaped projects in a browser IDE on a flat plan with unlimited candidates. If you want a calibrated score, CodeSignal. If you mostly run live interviews, CoderPad. If procurement needs SOC 2 and ISO 27001, Codility. If budget is the constraint, Coderbyte. Below is what each tool actually asks candidates to do, how it charges, and where it falls short, using facts from each vendor’s public pages. Kendor is our product, so we also say plainly when HackerRank is the better choice. ## At a glance | Tool | Best for | What candidates do | Pricing | |---|---|---|---| | **Kendor** | Teams hiring on real project work who want to see how it was built | Real projects in a browser VS Code IDE with a terminal, live preview and databases, plus single-file, SQL and free-form questions; live coding in the same workspace | Flat, never per candidate: Starter $79/mo; Pro $400/mo billed yearly ($500 monthly) with unlimited candidates, interviews and reviewers | | **CodeSignal** | Ranking large applicant pools with a calibrated score | Standardized timed tests: the General Coding Assessment is 4 algorithm questions in about 70 minutes | Tiered plans from about $79/mo (annual) to about $479/mo Grow, custom above (mid-2026) | | **CoderPad** | Lightweight live coding on a shared pad | Live pad exercises and library-based screening tests in a collaborative editor | Per session: a free tier of about 2 sessions/mo; about $80–120/mo for 5 interviews or tests, about $25 each extra (mid-2026) | | **Codility** | Enterprise procurement and high-volume, auto-scored screening | Library tasks, custom tasks built with its team and AI-focused tasks; shared VS Code with a terminal in live interviews | Invite credits: Starter $1,200/yr for 1 user and 120 credits; Scale about $6,000/yr for 3 users and 300 credits; custom plan by quote (Oct 2026) | | **Coderbyte** | Filtering a large pipeline on fundamentals on a small budget | Library challenges, multiple-choice and open-ended questions, scored automatically | Per user: about $199/user/mo standard, steep annual discounts, unlimited candidates (mid-2026) | ## Our position: AI informs, people decide Kendor has no AI interviewer, no AI filtering, no AI score and no automated rejection. Candidates put real time into their work, so a person reviews every submission and makes every decision. AI gives that person insights: a summary of what was built and how, with links to the code, never a verdict. ## Why teams look for a HackerRank alternative Most teams leave over one of two things. The first is the meter: HackerRank’s published plans charge per candidate attempt, $79 a month for 60 attempts a year or $419 a month for 360, with $20 for each extra attempt, so a busy hiring month costs more. The second is signal. A timed algorithm puzzle tells you how someone does on puzzles. Teams hiring for product work increasingly want to see a candidate build a feature in a real codebase, often with the AI tools they would use on the job. ## 1. Kendor The pick when you want the screen to look like the job: a real project instead of a puzzle, and a flat price instead of a per-attempt meter. Kendor screens candidates on job-shaped work: a Node/TypeScript, PHP/Laravel, Python, Go, Java, Rust or C++ project, from a template or imported from your own Git repository, running in a full VS Code-based IDE in the browser with a terminal, a live dev-server preview and a PostgreSQL or Redis-compatible database when the task needs one. Reviewers judge the work itself: the code and its diff, the terminal and AI-agent transcripts, and a keystroke playback of how it was written. When the organization allows it, candidates run Claude Code, Codex, GitHub Copilot, Cursor, Cline, OpenCode or Antigravity in the terminal, on the organization’s own API key or on their own account, which costs the organization nothing. **Strengths** - Real project workspaces, including your own repository from any Git host - An optional explain-your-code check: timed questions about the candidate’s own changes, with no editor or AI - Seven AI agents in the terminal on every plan, including Claude Code, Codex, GitHub Copilot and Cursor, on your API key or the candidate’s own account - Flat pricing with unlimited candidates; free trial with a work email, no sales call - Ashby, Greenhouse and Lever included in Pro - EU-hosted (Frankfurt), signable DPA; interface and candidate emails in 7 languages **Watch out for** - No automatic score: a person reviews every submission - Not built to rank thousands of applicants on standardized questions - No SOC 2 report or ISO 27001 certificate yet ## 2. CodeSignal The closest like-for-like swap: still standardized algorithm tests, but built around one calibrated score. CodeSignal’s flagship is the General Coding Assessment, a standardized, timed algorithm test that produces a normalized score designed to be comparable across candidates, with proctoring and ID verification protecting it. **Strengths** - A psychometrically calibrated, comparable score - Proctoring and ID verification - A separate interview product, and an AI Interviewer that speaks 20+ languages **Watch out for** - You get a score band, not the work itself - Timed puzzles reward contest practice; formal retake limits apply - No AI agents; candidates can’t create Docker containers in its terminal environments - Assessments in English Full comparison: https://kendor.io/vs/codesignal.md ## 3. CoderPad Worth a look if most of your HackerRank use is live interviews rather than take-home screens. CoderPad’s core product is an excellent shared pad for live interviews: a collaborative editor with language runtimes, plus library-based screening tests and session playback. **Strengths** - A polished live pad that teams adopt in minutes - A free tier for a handful of sessions a month - Interview questions can be localized into 30+ languages - Claude Code and Codex as agents in multi-file pads, on Enterprise plans **Watch out for** - A pad with runtimes, not a project workspace - Pricing meters interviews and tests - AI Assist chat is on in every pad by default - Containers are capped at 512 MB of RAM in live pads and 2 GB in projects Full comparison: https://kendor.io/vs/coderpad.md ## 4. Codility The enterprise alternative, with a similar library-and-auto-score approach and strong compliance paperwork. Codility is an established assessment platform with automated scores on library tasks, session replay and interviewer scorecards, and the certifications large procurement teams ask for. **Strengths** - States SOC 2 Type II and ISO 27001 certification, with US or EU data residency - ID verification and video proctoring on higher plans - Workday, SmartRecruiters and SAP integrations alongside Greenhouse, Lever and Ashby **Watch out for** - Sold in invite credits, one per screen or interview - SSO, ATS integrations, interview recording and Claude Code sit on the custom plan - Interface in English Full comparison: https://kendor.io/vs/codility.md ## 5. Coderbyte The budget option: library questions with automatic scores and unlimited candidates, priced per user. Coderbyte is a pragmatic, inexpensive screening tool: library challenges, multiple-choice and open-ended questions scored automatically on test cases, with cheating-detection features and an interview add-on. **Strengths** - Inexpensive, with unlimited candidates - Minimal setup: library questions with automatic scores - An interview add-on **Watch out for** - Library questions rather than job-shaped work - Priced per user, so adding reviewers costs more - No AI agents; interface in English Full comparison: https://kendor.io/vs/coderbyte.md ## When to stay on HackerRank If you screen thousands of new grads or run campus hiring on standardized questions, HackerRank is built for exactly that: a 7,500+ question library, certified assessments, 40+ ATS integrations and auto-scored funnels at scale. None of the alternatives here beats it on sheer volume. ## Frequently asked questions ### What is the best free HackerRank alternative? None of these tools is free for ongoing hiring. CoderPad has a free tier of about 2 sessions a month, which suits occasional live interviews. Kendor has a free trial you start yourself with a work email, then flat plans from $79 a month with unlimited candidates. ### Which HackerRank alternative lets candidates use AI? Kendor lets each organization decide per assessment, and runs Claude Code or Codex in the sandbox terminal on the organization’s own API key on every plan. CoderPad offers agents on Enterprise plans, and Codility lists Claude Code in preview on its custom plan. ### Which alternative is cheapest for a small team? It depends on what you meter. Kendor’s Starter is $79 a month with unlimited candidates for up to 3 reviewers. Coderbyte is priced per user with unlimited candidates. CoderPad and Codility meter sessions or invite credits, so they suit low volumes. ### Is there a HackerRank alternative that hosts data in the EU? Kendor is built and hosted in the EU (Frankfurt) with a signable DPA, data export and erasure. Codility states US or EU data residency. --- More: [site overview for LLMs](https://kendor.io/llms.txt) · [full content](https://kendor.io/llms-full.txt) · [kendor.io](https://kendor.io/)
