The best Codility alternatives in 2026
Facts last reviewed: August to October 2026
The best Codility alternative depends on what you want to change. If you want candidates working in your own repository with their AI tools, and a plan you can start today without a sales call, Kendor. For an even bigger question library, HackerRank. For a calibrated score, CodeSignal. For lightweight live interviews, CoderPad. On a tight budget, Coderbyte.
Here is what each tool asks of candidates, how it charges and where it falls short, using facts from each vendor’s public pages. Kendor is our product, so we also say when Codility is the safer 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 |
| HackerRank | High-volume and campus hiring on standardized questions | Algorithm puzzles from a 7,500+ question library; project questions exist but are not the centre | Per candidate attempt: $79/mo for 60 attempts/yr or $419/mo for 360, $20 per extra attempt (Oct 2026) |
| 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) |
| 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) |
Why teams look for a Codility alternative
Codility’s self-serve plans are sold in invite credits: Starter is $1,200 a year for one user and 120 credits, and one credit is spent per screen or interview invite. SSO, ATS integrations, interview recording and Claude Code are listed under the custom plan, so the features many teams want need a quote.
Teams also want screens that look like the job. Library tasks are consistent and easy to score, but they don’t show how someone works inside a real codebase.
1. KendorOur product
The pick when you want your own codebase in the interview, Claude Code and Codex on every plan, and unlimited candidates on a flat price.
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. HackerRank
The closest swap: a larger library and automatic scores, metered per candidate attempt.
HackerRank is a content-and-scale platform: a library of 7,500+ questions, certified assessments and integrations for screening very large applicant pools. Most screens are algorithm and data-structure questions answered in a hosted code pad.
Strengths
- The largest question library, with automatic scoring
- Tiered proctoring, up to a desktop app with OS-level lockdown
- 40+ ATS integrations
- A separate DevOps question type on a Linux VM, scored by a script
Watch out for
- Pricing meters every candidate attempt
- Screens centre on puzzles rather than day-job work
- AI use only through its own assistant inside its IDE
- Candidate-facing language: English or Canadian French
3. CodeSignal
Standardized timed tests with a calibrated score, if consistency across huge pools matters most.
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
4. CoderPad
A lighter tool if live interviews are most of what you use Codility for.
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
5. Coderbyte
A cheaper auto-scored screen with 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
When to stay on Codility
If your procurement requires a SOC 2 report or an ISO 27001 certificate today, if you screen at high volume with standardized, auto-scored tasks, or if you need ID verification, video proctoring or Workday and SAP integrations, Codility is built for that and has the track record.
Frequently asked questions
Is there a Codility alternative without invite credits?
Kendor never charges per candidate or per interview: Starter is $79 a month, Pro is $400 a month billed yearly ($500 month to month), with unlimited candidates, interviews and reviewers. Coderbyte has unlimited candidates on a per-user price.
Which Codility alternative includes ATS integrations without a custom plan?
Kendor’s Pro plan includes Ashby, Greenhouse and Lever: moving a candidate to a stage you choose sends their screen or a booking link, and progress is reported back to the ATS.
Which alternatives offer Claude Code?
Kendor includes Claude Code and Codex on every plan, in take-home screens and live coding. CoderPad offers agents on Enterprise plans. Codility lists Claude Code in preview on its custom plan.
Do any alternatives match Codility on compliance?
Not among the self-serve options here. Kendor is EU-hosted with a signable DPA, export and erasure, but has no SOC 2 report or ISO 27001 certificate yet. HackerRank and CodeSignal run enterprise compliance programs whose terms vary by plan.
