Codility - 2026 Pricing, Features, Reviews & Alternatives

Codility is a coding assessment and technical interview platform that brings developer screening, live coding interviews, and workforce skills intelligence into one connected hiring workflow. AI can write code now, so the question is no longer who knows the syntax. It is who can actually build. Codility gives engineering and talent teams that signal, on assessment methodology that holds up when results are questioned.

Screen candidates at scale

Send take-home coding assessments and real work simulations drawn from a library of 1,300+ tasks across 80+ programming languages and frameworks. Assess Java, Python, JavaScript, TypeScript, C++, C#, Go, Ruby, and SQL, plus frameworks including React, Angular, Node.js, Spring Boot, Django, .NET, Kubernetes, and Terraform. Task types span real-life project work, algorithmic problems, coding, SQL, and multiple choice, so you can match the assessment to the role. Automatic scoring on selected tasks shortlists strong engineers faster and gives every candidate the same objective measure.

Run technical interviews in a real environment

Interview candidates live in a shared VS Code workspace with terminal, sidecar services, a whiteboard, and a full transcript. Remote technical interviews and video interviewing run in one place, with pair programming and structured rubric scoring, so every interviewer evaluates the same way. You see how an engineer thinks, debugs, and builds in real time, and you build relationships with the best candidates sooner.

See the skills you already have

Use Skills Intelligence to assess and develop the technical skills of your current engineers on the same methodology you use to hire. Surface skills gaps, compare proficiency across teams, and guide staffing, project allocation, internal mobility, and targeted training. One data model runs from external candidate to internal engineer.

Assess how candidates work with AI

Modern engineering means working alongside AI. Codility lets you enable or disable the in-assessment AI assistant per assessment and captures every candidate interaction as reviewable AI activity, so you can evaluate how engineers prompt, review, and debug with AI.

Methodology you can trust

Codility tasks are designed by occupational psychologists, validated by engineering leaders, and mapped to a structured engineering skills model. Every assessment produces a defensible, reviewable record, so you get scores you can stand behind and a process candidates respect.

Hire fairly and defensibly

Layered integrity controls, from similarity checks to behavioral signals and risk scoring, give you reviewable evidence and human accountability on every assessment, without a heavy proctoring burden on candidates. Adverse impact monitoring supports a fairer process, and an explicit EU AI Act posture means no AI or machine learning makes automated hiring decisions.

Built for how you hire

Codility supports backend, frontend, full-stack, mobile, data, DevOps, platform, and QA hiring, from high-volume graduate and early-careers pipelines to senior and staff engineers. It connects to Greenhouse, Lever, Workday, SmartRecruiters, and 80+ ATS and HRIS systems, with SSO and API access, and meets SOC 2, ISO 27001, and GDPR requirements.
