Detailed Review
Codility is the closest like-for-like swap for HackerRank in this list: it screens developers with coding tasks, runs live interviews and flags plagiarism. The terms of service name Codility Limited, a company registered in England and Wales under number 07048726 with its registered office on Cheapside in London, and they are governed by the law of England and Wales.
Candidates take assessments inside VS Code with package installation, a terminal and multi-file projects, and the vendor also sells a library of AI-skill tasks that check how a candidate prompts and debugs AI-generated code. Pricing is shown openly, in US dollars, which is rare in this category.
How the test environment works
The assessment runs in a VS Code environment. According to the vendor, candidates get full tooling, a terminal, documentation and multi-file projects, so a reviewer sees how a person works rather than how they handle a single-function puzzle.
Task leakage protection is part of every plan: tasks that leak are removed from the library. Plagiarism detection and basic proctoring with candidate snapshots are included from the Starter plan.
What the plans include
Starter costs $1,200 a year with annual billing only, up to 120 invite credits and one platform user, drawn from a limited task library. Scale costs $6,000, adds a larger library, three users and custom task building from your IDE through MCP, with a cap of 25 invites a month inside the 300 yearly credits.
The Custom tier adds unlimited users, role-based access, an Assessment Science advisory team and a Skills Intelligence module that maps what a current engineering team can do. Prices are on request for that tier.
Jurisdiction in practice
Codility is a UK company, so it sits outside the EU but under the UK GDPR and English law, not US law. The privacy policy states that data may be transferred outside the EEA under lawful mechanisms such as standard clauses, so the hosting location is worth asking about before signing.
Limitations to Consider
Codility is built for engineering hiring only, so it will not cover personality or cognitive screening for non-technical roles (for that see Alva Labs or AssessFirst). Plans are priced in US dollars with invite credits, annual billing on Starter and a one-user cap, which is tight for a team where several recruiters need access. The pages read do not say where candidate data is hosted.
Who Should Use Codility
Engineering organisations that want a HackerRank-style coding screen from a company registered in England and Wales, and that prefer published plan prices over a sales call.
