# Codility Alternative: Candidate-Owned Skill Evidence > Codility runs engineering screens and interviews in a real IDE. Lemma gives candidates a record of skill evidence. How they compare and when to use each. Source: https://getlemma.io/compare/codility Codility helps engineering teams screen and interview developers in a realistic coding environment. Lemma helps people build a record of skill evidence they keep. One runs your process; the other feeds it. See the comparison ## How does Lemma compare with Codility? Codility is a technical assessment platform for hiring teams: take-home screens, structured interviews in VS Code, and Skills Intelligence for mapping an engineering team. Lemma is a candidate-owned record, built from rated sessions, adaptive assessments and linked work, with an SCI score per skill that stays with the person. Codility and the Lemma Skills Passport compared | Dimension | Codility | Lemma Skills Passport | | --- | --- | --- | | Who runs it | The hiring company or engineering leader, who sets tasks and reviews results | You build the Passport; companies view it or invite you to an assessment | | Test environment | Real-world tasks; interviews in VS Code with a terminal, packages and multi-file projects | Adaptive assessments of 15 to 25 questions, plus live sessions with another practitioner | | AI in the test | Employers choose how candidates may use AI; tasks can assess judging and debugging AI output | Assessments log signals such as tab switches and pastes for a person to review | | Result | Results and code analysis for the company, for that role or team | An SCI score per skill that stays on your Passport and keeps updating | | Existing team | Skills Intelligence maps an engineering organisation's skills | Each person's evidence lives on their own Passport, across every skill | | Skills covered | Software engineering roles | Technical and non-technical skills, from code to design and product | ## What does Codility do well? Codility is built around realistic engineering work. Candidates code in a real IDE with the tools they would use on the job, and teams can decide how AI may be used rather than pretending it does not exist. - Interviews in VS Code with a terminal, packages and multi-file projects - Automated code analysis for quality, maintainability and complexity - Identity verification, impersonation detection and proctoring Checked against Codility's own pages on 14 October 2026. Sources ## What does Lemma add to a Codility screen? A screen tells one company how a candidate did on its tasks. Lemma adds evidence gathered over months that the candidate brings with them. ### Evidence before the first task A Passport shows rated sessions, assessments and linked repositories or deployments before you spend an interviewer's hour. ### Owned by the candidate Evidence stays with the person, so a strong result is not lost when one application ends, and history counts alongside one sitting. ### A score with its reasons SCI is built from capped components (practice 25, proof 40, reliability 20, freshness 15) and every point traces to its source.

Choose Codility when you run a structured engineering hiring process and want candidates working in a realistic IDE, with clear rules for AI use and identity checks. It also fits engineering leaders who want a view of the skills inside their existing team. - Structured screens and interviews for engineering roles - Realistic, multi-file tasks with defined rules for AI use - Mapping skills across an existing engineering team ## When should you choose Lemma? Choose Lemma when you want evidence a candidate builds over time rather than a single sitting, when roles span engineering and non-engineering skills, or when you are a developer who wants a record you keep. Candidate invites and the verification API are in early access for selected teams. - Evidence built over months, not one sitting - Roles that mix engineering, design, data or product - Developers who want a record that is theirs ## Questions about Lemma vs Codility ### What are the alternatives to Codility? Other technical assessment platforms, including HackerRank and TestGorilla, offer coding screens or test libraries for hiring teams. Lemma takes a different route: candidates build a Passport of evidence they keep, and teams can view it or invite them to an assessment. ### Is Codility free? Codility's pricing page, checked on 14 October 2026, lists no free plan. Its Starter plan was listed at $1,200 with annual billing and up to 120 invite credits a year, alongside Scale and Custom plans. A free trial is available on request: Codility's team arranges it around your roles rather than through self-serve sign-up. ### Can Lemma replace Codility for technical screening? Not today, and not for every team. Codility runs proctored, role-specific screens at volume. Lemma is better used before or alongside a screen: a Passport tells you who to invite and what to probe, and candidate assessment invites are in early access. ### Do Codility results stay with the candidate? Codility results are produced for the company that ran the assessment. Codility also describes a skills profile for engineers built on demonstrated ability. A Lemma Passport is the candidate's own document, shared through a link they control. ![Painting of heather moorland with granite boulders and a distant lake](https://cdn.sanity.io/images/islu4peo/production/d420ed581b54d23f374657cfbffe19551f639884-1680x1120.jpg?w=1080&fm=webp&q=68&fit=max) ## Bring evidence, not just a profile. Lemma is in early access. Join the list to build a Skills Passport with evidence anyone can inspect.
