Our pickTestGorillaHiring teams that want a large general skills test library with a free plan to start and published paid tiers.8.8

Our pick in brief

TestGorilla ranks first because it pairs a library of 350+ skills tests with a permanent free plan, resume scoring and qualifying questions, and its paid Assessments plans are priced on the page. Testlify is close behind with a larger test library, job simulations and AI interviews on a single $139 plan. Adaface is the cheapest way to run a few tests a year. For developer hiring, HackerRank and Coderbyte publish low entry prices, while Codility suits teams that want AI-assisted coding tasks and task leakage protection. Canditech is a good fit for small teams that want customizable tests with a flat yearly price. Criteria is the science-heavy choice for cognitive and personality testing, and Vervoe and eSkill suit larger employers buying on annual contracts.

Quick answer

TestGorilla is the best pre-employment testing software for hiring teams screening skills before interviews in 2026, with a free plan of 10 credits a month and paid Assessments plans from $215 per month billed annually; Testlify suits teams that want tests, simulations and AI interviews on one plan from $139 per month billed annually. Adaface is the cheapest paid option at $180 a year for 12 credits.

This list is for recruiters, hiring managers and HR teams that want to test candidates' skills before spending interview time on them. It covers general skills test libraries, coding assessment platforms for engineering roles and science-led aptitude and personality batteries. We compared documented features and published prices for ten products. Each tool is scored on features, ease of use and value, weighted 35, 35 and 30, and the overall score is the weighted average. Prices are the cheapest paid plan in US dollars as shown on the vendor's pricing page on the date we checked. Criteria, Vervoe and eSkill only quote through sales, so their prices are marked as pending.

    Free plan with 10 credits a month; Assessments Core from $215 per month per account billed annually

    Quoted from the TestGorilla pricing page on November 7, 2026: Core from $215 /mo per account billed annually

    TestGorilla ranks first because it covers most screening needs for non-specialist roles and lets a team start without paying. The free Assessments plan gives 10 credits a month, five essential tests with unlimited use (problem solving, communication, time management, a Big 5 personality test and motivation), resume scoring and qualifying questions that filter candidates before they start. Core, from $215 per month per account on annual billing, opens the full library of 350+ tests, video questions and custom questions from a shared credit pool. Plus, from $520 per month, adds the AI interview library, job simulations, custom tests and coding challenges, ID verification, removal of TestGorilla branding and ATS and API integrations with Workday, Greenhouse, Lever, BambooHR and Ashby. Anti-cheating tools such as webcam snapshots, disabled copy and paste and full-screen mode are listed across plans. The main limit is that integrations sit on the higher tier, so connected hiring workflows cost more than the entry price suggests.

    Strengths

    • +Permanent free plan with 10 credits a month and five essential tests with unlimited use
    • +Paid tiers and credit rules are published on the pricing page
    • +Account credits are shared, and hiring manager roles are unlimited on every plan

    Starter plan $139 per month billed at $1,668 per year for 100 credits; Custom plan by quote

    Quoted from the Testlify pricing page on November 7, 2026: STARTER PLAN $139 /mo Billed at $1,668/year

    Testlify ranks second because its entry plan bundles more assessment types than most rivals charge extra for. The Starter plan costs $139 per month billed at $1,668 a year and includes 100 credits, which works out to $16.68 per candidate, and a credit is only used when a candidate starts. That plan covers unlimited assessments, a library of 3,500+ tests, custom tests and coding challenges, role-based simulations in Microsoft Office and Google Workspace, and AI video, audio and phone interviews, with phone time billed at $0.18 per minute. The proctoring list is long and included: face detection, tab and mouse tracking, multiple monitor restriction, session recording and AI assistance detection. The costs come from add-ons. ATS integrations and white labeling are $2,388 a year each, photo ID checks are $0.50 per attempt and live video proctoring is $5 per attempt. Teams that only need Greenhouse can use its free AI resume scoring integration.

    Strengths

    • +A credit is used only when a candidate starts an assessment
    • +Unlimited assessments and custom questions on the Standard plan
    • +30-day money-back guarantee listed on the pricing page

    Drawbacks

    Individual plan $180 per year for 12 credits; larger packs from $500 per year

    Quoted from the Adaface pricing page on November 7, 2026: Individual $180/ year 12 credits/ year

    Adaface ranks third on value. It is the cheapest paid way into skills testing on this list, and every plan price is on the page. The Individual plan costs $180 a year for 12 credits, Starter is $500 for 50 credits and Pro is $900 for 100. Credits are spent in a simple way: 5 to set up a ready-to-use test, 10 for a custom test and 1 per candidate invite, and the invite credit comes back if the candidate never takes the test. The library spans programming languages, IT platforms such as SAP, Salesforce and Power BI, machine learning, cognitive ability, the Big 5 personality model, languages, typing and finance, so one account can cover technical and business roles. Proctoring options and ATS integrations are listed as features. The small plans fill up fast once setup credits are counted, so a team testing more than a few dozen candidates should start at Pro or Scale.

    Strengths

    • +Lowest published entry price on this list at $180 a year
    • +Credits are added back if an invited candidate does not take the test
    • +Plans scale in clear steps up to an unlimited plan for staffing firms

    Drawbacks

    • −The Individual plan's 12 credits only cover a ready-to-use test and a few invites
    • −Each test costs credits to set up: 5 for a ready-made test and 10 for a custom one
    • −Only annual plans are listed

    Quoted from the HackerRank pricing page on November 7, 2026: $79 /mo $948 billed annually

    HackerRank is the strongest coding test pick for small teams on price. Starter costs $79 per month on annual billing, $948 a year, and includes unlimited users, 60 candidate attempts a year, the Screen take-home assessments, the Chakra AI interviewer, pair programming interviews and 2,000+ library questions. Every plan includes the agentic IDE, where candidates can work alongside Claude, Gemini or GPT models in a full IDE with a terminal, and hiring teams can run tests in guarded or unguarded mode. Integrity tools on all tiers include AI-powered plagiarism detection, session replay, device and object detection and standardized integrity reports. Pro, at $419 per month billed annually, raises the allowance to 360 attempts and adds Greenhouse, Lever and Ashby integrations and 4,000+ questions. The limits show at volume: extra attempts cost $20 each, and SSO, API and MCP access and leaked question protection need an Enterprise contract. It also only tests technical roles.

    Strengths

    • +Unlimited users on Starter and Pro
    • +Covers screening, AI interviews and live interviews on every plan
    • +Guardrail controls let you allow or restrict AI use per test

    Drawbacks

    • −Starter includes only 60 candidate attempts a year, with extras at $20 each

    Quoted from the Canditech pricing page on November 7, 2026: Team $150/ Month Billed Yearly

    Canditech fits small teams that want job-like tests rather than generic quizzes. The Team plan costs $150 per month billed yearly at the 100-candidate level and includes two assessments, eight users, 500+ pre-built tests that can be fully customized, the AI Assessment Builder and question types for open text, multiple choice, video, Excel and file uploads. Cheating prevention and employer branding packages are included, with question timers, copy and paste detection and IP and location tracking. Pro, at $200 per month billed yearly, removes the limits on assessments and users and adds ATS integration, coding questions in languages from Python and Java to React and SQL, and embedded Google Sheets questions. Enterprise adds AI auto scoring agents, monitored ChatGPT and Google Search, webcam snapshots, SSO and API access. Prices on the page scale with the number of candidates a year, so check the slider for your volume. The two-assessment cap on Team means most growing companies will land on Pro.

    Strengths

    • +Free start with no credit card needed
    • +Pro removes limits on assessments and users
    • +Embedded Google Sheets and Excel questions suit analyst and operations roles

    Drawbacks

    Quoted from the Coderbyte pricing page on November 7, 2026: Monthly $99 /mo for 20 invites Cancel anytime.

    Coderbyte stands out for pricing that does not count candidates. Pro costs $1,999 a year and covers unlimited candidates and admins, with screening, assessments and interviews, the full question library, custom questions, a native IDE and VS Code, automated grading, cheating detection and AI features with unlimited credits. Coderbyte says the Pro price stays locked for as long as you auto-renew. Teams that hire in bursts can use the Monthly plan at $99 for 20 invites, with $20 per extra invite and rollover of unused invites, or buy 60 invites for $799. Assessments can include algorithmic challenges, multi-file projects and take-home work. The cost rises with add-ons: API, ATS and MCP integrations, SSO and SCIM, branding, premium analytics and proctoring, and personality testing are each $1,499 a year, or $4,496 for the bundle. A team that needs an ATS connection should price Pro plus that add-on against HackerRank Pro.

    Strengths

    • +Pro includes unlimited candidates and admins for $1,999 a year
    • +Pro pricing stays locked for as long as you auto-renew
    • +Monthly plan can be cancelled anytime, and unused invites roll over

    Quoted from the Codility pricing page on November 7, 2026: From $4,800 a year, or from $800 a month

    Codility is built for teams that want to see how engineers work with AI, not only whether they can solve a puzzle alone. Online plans start at $4,800 a year, or $800 a month for 25 invites, and include Screen and Interview, five platform users with unlimited collaborators, one standard ATS integration and integrity tools such as plagiarism detection, proctoring with snapshots and task leakage protection. Every plan includes Claude Code and Codex set up in the terminal and an AI Assistant on models up to Sonnet class, and each prompt, command and code change is saved with the result. Hiring teams can turn AI off for a task when they want to see unaided work. The task library grows with the plan and reaches the full 1,300+ validated tasks at 1,000 invites a year. Enterprise adds AI skills tasks for sales, marketing and finance roles, ID verification, video proctoring, SSO and every ATS integration, including Workday and SAP. The entry price is high for a team hiring a few engineers a year.

    Strengths

    • +AI can be switched on or off per task or interview
    • +Online plans can be bought by card without a sales call
    • +Publishes a technical manual on how tasks are designed and scored

    Drawbacks

    We could not confirm a US price yet. Check the Criteria pricing page.

    Criteria is the pick for employers who want to measure how candidates think and work, not just what they know. Its Criteria Assess package includes all of its assessments, covering cognitive aptitude, personality, emotional intelligence, risk and skills, plus game-based tests, the TestMaker tool and template library, non-AI proctoring, a branded candidate experience, standard ATS integrations and SSO. Criteria Interview adds async and real-time video interviews with transcripts and summaries, and Criteria Hire combines both. Upgrades add AI proctoring, AI scoring and an AI interview agent, and the Develop add-on extends the platform to post-hire coaching. Criteria describes its pricing as a flat-fee subscription, which means candidates can be tested at any stage of the funnel without per-test charges. The trade-off is that no prices appear on the site, so it is hard to compare with self-serve rivals, and smaller teams must book a call to learn the cost.

    Strengths

    • +Flat-fee subscription pricing keeps costs predictable regardless of how many candidates you test
    • +Breadth of science-backed aptitude and personality tests
    • +Customer success team helps choose and interpret assessments

    Drawbacks

    • −No prices are published; every package is quoted
    • −AI proctoring and AI scoring are paid upgrades
    • −Video interviewing is a separate package unless you buy the full Hire suite

    Vervoe suits employers that want candidates to do a sample of the actual job and have the answers graded consistently at scale. Its assessments are built on real job tasks, and the AI Assessment Builder generates role-specific tests that the hiring team can adjust. Responses are graded by AI that Vervoe describes as explainable and auditable, and the platform includes advanced generative AI detection to flag answers written by tools. On the governance side, Vervoe lists SSO, regional data storage, an uptime SLA, GDPR compliance, ISO/IEC 27001 certification and an independent bias audit by Holistic AI, which matters for regulated or large employers. Enterprise customers can use the API and white-label workflows to run assessments inside their own systems, and the same tools can assess current staff for internal moves. The drawback for smaller teams is clear: there is no published price or self-serve plan, so buying starts with a demo.

    Strengths

    • +Independently audited for bias by Holistic AI
    • +ISO/IEC 27001 certified, with regional data storage
    • +Also used for internal moves and AI readiness checks of current staff

    Drawbacks

    eSkill is a long-running skills testing platform aimed at organizations that hire consistently through the year. Its library holds more than 70,000 questions across 600+ subjects, verified by subject matter experts, and recruiters can use standardized tests or mix questions from different subjects into a custom test, or write their own. The Growth plan screens up to 500 candidates a year and includes the full library, behavioral tests, ATS integrations with more than 100 providers and custom branding. Scale, the most popular tier, covers up to 1,000 candidates and adds one-way interviews, custom questions, test uploads and team grading. Custom adds white glove help, test analysis and assessment consulting. There is no limit on users. eSkill requires an annual subscription and publishes no prices, and AI-powered proctoring is an add-on even on the top plan, so teams should ask for the full quote with proctoring included.

    Strengths

    • +No limit on users or seats
    • +Plans set by screening volume: up to 500 or 1,000 candidates a year
    • +Assessment experts help build and refine tests

What to check before you buy

Match the test library to the roles you hire

General libraries such as TestGorilla, Testlify, Adaface and eSkill cover sales, support, finance, admin and software skills. HackerRank, Codility and Coderbyte focus on engineering roles with real coding environments. Criteria leans on cognitive aptitude, personality and emotional intelligence tests. List your next ten open roles and check that each one has a ready-made test before you compare prices.

Understand what a credit or invite costs

Most vendors meter candidates. Testlify charges one credit when a candidate starts, Adaface refunds the credit if the candidate never takes the test, HackerRank counts candidate attempts and Codility counts invites. Divide the plan price by the number of candidates it covers, then check the overage price: HackerRank and Coderbyte both list $20 per additional attempt or invite, and Testlify lists $21 per additional credit.

Check the integrity features on your tier

Remote tests are only useful if you trust the results. Look for webcam snapshots, copy and paste tracking, full-screen mode, plagiarism detection and AI assistance detection. Several vendors keep ID verification, video proctoring or a desktop lockdown app for upper tiers or charge per attempt, so confirm what your plan includes.

Decide how AI should be treated in coding tests

Engineers now work with AI agents, and coding platforms handle this differently. HackerRank offers an agentic IDE with guardrail controls, Codility lets you switch its AI Assistant on or off per task and saves every prompt, and Canditech's enterprise plan includes monitored ChatGPT. Decide whether you want to test unaided skill, AI-assisted skill or both.

Plan for ATS integration costs

Sending results back to your applicant tracking system saves recruiter time, but it is not always on the entry plan. HackerRank adds ATS integrations on Pro, Canditech on Pro, TestGorilla on Plus, and Testlify and Coderbyte sell them as add-ons. Price the plan you will actually need once the tool is connected to your hiring process.
