TestDome vs HackerRank: Proctored Testing Cost and Features Compared

In one line: for most small and mid-sized teams hiring across roles, pick TestDome: pay-per-candidate at a public price, with AI-grade proctoring (AI-analysed monitoring plus a locked-down test environment) included on every pack, while HackerRank gates it to Pro. Pick HackerRank if you hire developers at high volume, rarely hire for other roles, and its deeper coding-only library or a specific enterprise integration justifies the higher committed price.

Key points

• Cost, matched on proctoring: TestDome is lower at every volume once you match on AI-grade proctoring. HackerRank includes that proctoring only from Pro ($449/mo for 25 candidates, or $4,490/yr). The gap is narrow only at a single 25-candidate month. Beyond that month it widens fast, and TestDome's packs never expire while Pro's monthly cap resets. High volume moves HackerRank to a negotiated Enterprise quote.
• Same category of proctoring, gated differently: both ship AI-analysed monitoring and a locked-down app. TestDome includes them on every pack. HackerRank gates monitoring, ID verification, and the app to Pro, so its Starter plan gets plagiarism and leaked-question checks only. The difference is availability and price, not capability.
• HackerRank goes deeper on coding, TestDome goes wider: HackerRank has 7,000+ questions across 77 roles and 260+ skills, all technical. TestDome has 2,000+ questions across 130+ skills and adds non-coding tests HackerRank does not offer.
• Opposite approaches to AI skill: TestDome scores unaided skill separately from AI skill. HackerRank blends AI collaboration into one rubric-graded result.

How to read this comparison

This page is a decision guide for a 2026 developer-hiring team, and TestDome wrote it. Every competitor fact on this page cites HackerRank's own published pages, and we link them so you can check each one. Where HackerRank is the better choice, we say so. This page compares the needs that decide the purchase, in depth, and is not a complete feature inventory. Features outside those needs are deliberately out of scope. Each vendor's own site lists its full feature set. We weigh three must-haves first, because a developer screening step fails without them:

• The tool has to defend against a candidate using a hidden AI assistant. That takes AI-analysed monitoring plus lockdown, which goes well beyond basic plagiarism checks.
• The tests have to predict real performance, which takes job-relevant tasks that cover your roles.
• The cost and commitment terms have to fit how you actually buy.

After the must-haves come the nice-to-haves that separate TestDome and HackerRank: how each measures AI skill, which integrations each connects to, and how far each goes beyond technical roles. Working with AI is now part of the job, so it belongs in your screening. The full argument is in our piece on assessing developers in the AI era.

Two rules keep the cost side honest. We take each vendor's cheapest option that includes AI-grade proctoring and compare at equal candidate volumes. And every price is the vendor's own published figure, so you can confirm each one on the TestDome and HackerRank pricing pages. Where a vendor stops publishing a number, such as HackerRank's Enterprise pricing, we say so instead of guessing.

What does proctoring cost on each?

Matched on the proctoring a 2026 hiring test needs, TestDome is lower than HackerRank at every candidate volume. TestDome sells per-candidate packs from $100 for 5 candidates, AI-grade proctoring included. HackerRank's proctored Pro plan starts at $449 a month or $4,490 a year. HackerRank reserves the monitoring and locked-down app that defend against a hidden AI assistant for Pro. Its cheaper Starter plan has plagiarism checks only.

The threat a coding-test proctor has to stop in 2026 is a hidden AI assistant: an invisible overlay assistant (a window only the candidate can see) or a second device feeding the candidate answers while they appear to work unaided. Both vendors defend against that threat the same way. On TestDome that defense is on from the first candidate, on every pack. Safe Exam Browser locks the test machine and shuts down disallowed processes. That blocks a hidden AI assistant from running on it. AI-analysed screen recording flags tools like ChatGPT or DevTools when they appear on the candidate's screen. AI-analysed webcam proctoring watches for outside help on a single camera. The webcam catches a phone used off to the side, though not a device held fully out of frame.

No lockdown catches everything, and TestDome does not claim otherwise. The lockdown blocks tools that try to run on the test machine. But an overlay assistant can be fed from a separate device. That gap is why the screen and webcam layers matter, and why TestDome also lets you assess unaided skill separately.

HackerRank ships the same category of tooling, including a locked-down app, but reserves that tooling for its Pro plan. So the fair cost comparison takes each vendor's cheapest option that includes this proctoring, at equal candidate volumes. On TestDome, any pack qualifies. On HackerRank, that option is Pro: $449 month-to-month for 25 candidates, or $4,490 annually for 300, with $20 per attempt over the cap. HackerRank's cheaper Starter plan is left out on purpose, because it lacks that monitoring and lockdown.

HackerRank's monthly figures above assume you spread testing at about 25 candidates a month. A concentrated burst hits the monthly cap sooner (100 candidates in a single month cost $1,949, rather than the $1,796 shown in the table). So for a burst larger than the 25-candidate monthly cap, HackerRank's annual plan is the better buy.

HackerRank only comes close at one point: a single 25-candidate month, where TestDome costs $400 and a month of Pro costs $449. Even there, TestDome's 25 candidates never expire, while HackerRank's cap resets the next month. The month-to-month plan is still HackerRank's real strength for a one-off batch that fits inside one month. Beyond that single point the gap widens. HackerRank's per-month fee and 25-candidate monthly cap add up faster than TestDome's per-candidate rate. That rate keeps falling as you buy more: $8 a candidate by 300, $7 by 600, $6 by 1,200, and lower on the custom packs above that. The rate you reach applies to the whole order, so an order of 2,000 candidates costs $6 each, or $12,000 in total. Above its 300-attempt cap HackerRank stops publishing prices and switches to a custom Enterprise quote. At its list overage rate, the total would run to roughly $10,490 at 600 candidates and $38,490 at 2,000, but treat those figures as projections, because at that volume HackerRank sells through a negotiated quote only. TestDome's price stays public all the way up. For a team testing in the thousands, that transparency matters as much as the saving itself.

TestDome does not gate features by pack size, either. Every pack carries the proctoring, ATS integrations, API, SSO, and multi-user access. A bigger pack only lowers the price per candidate, and even the smallest pack is the full product.

How do TestDome and HackerRank compare at a glance?

The table below lines up the two vendors on the dimensions that usually decide the purchase. The sections after it go deeper on each.

Which has the better test library?

HackerRank goes deeper on coding: 7,000+ questions across 77 roles and 260+ skills, all technical. TestDome carries 2,000+ questions across 130+ skills as work-sample tasks and adds non-coding tests HackerRank does not offer. Coding depth is HackerRank's lead, and breadth across roles is TestDome's.

TestDome builds its questions as work-sample tasks, small pieces of the real work the job involves. Its 2,000+ questions span 130+ skills across coding and non-coding: logical, numerical, verbal, and abstract reasoning, attention to detail, teamwork and communication, MS Excel and Office, and business and finance roles. You can combine questions from different skills into a single test. A hiring manager screening an analyst can pull reasoning, Excel, and domain knowledge into one test instead of running candidates through separate tools.

HackerRank's library is built for one job, developer hiring, and it goes deep: more than 7,000 questions across 77 roles and 260+ skills, all technical. If you screen exclusively for coding roles and want granular coverage across languages and frameworks, that depth is real. TestDome's 2,000+ questions don't match it question-for-question on coding.

TestDome's coverage is deep on mainstream developer stacks. If you hire for a niche technology or a less-common framework, check that TestDome's catalog lists your exact role before committing.

How does each handle AI in the assessment?

Both assess how candidates work with AI, but they differ in how they report it. TestDome scores unaided domain skill separately from AI skill and ships dedicated AI-skills tests (AI Literacy, Prompt Engineering, LLM Engineering, and more). HackerRank blends AI collaboration into the test and grades it on a rubric.

The split shows up in how each reports the result. HackerRank reports one combined result: candidates work with AI tools inside the test, and their AI fluency is graded on a rubric alongside everything else. TestDome splits the result in two, with both halves inside one test. A pass on the unaided portion tells you the person can do the work themselves. Skill at directing an AI assistant shows up in the AI-skill score instead. We make the full argument for building that separation into your hiring bar in assessing developers in the AI era. The same split plays out against Codility and TestGorilla if you are weighing more than one vendor.

When is HackerRank the better choice?

• You want the deepest available coding-specific library and you don't need non-coding tests.
• You need formal photo-ID verification as a hard requirement, beyond a webcam presence check.
• The live-coding interview matters to you. HackerRank's developer-native IDE is a step more polished than TestDome's for real-time pair-coding, and candidates recognize the familiar, developer-respected HackerRank environment. Relevance to the role still shapes how candidates feel about a test more than the platform does.
• Your hiring workflow is already built around HackerRank. Maybe HackerRank connects to an ATS or calendar tool TestDome does not integrate with yet. Or your team has standardized on HackerRank, and the cost of migrating tests, integrations, and process outweighs the yearly savings.

If you're leaning toward TestDome, trying it costs almost nothing to start. It's self-serve: you build a test and run it on real candidates on a single starter pack, with no sales call and no annual contract between you and a first real result. One caveat: TestDome's list of native ATS connectors is shorter than what large enterprise platforms like HackerRank offer. If you depend on a specific integration, confirm it's covered (or that the REST API fills the gap) before you switch.

TestDome vs HackerRank FAQ

Is TestDome a good HackerRank alternative?

For most developer-hiring teams, yes. TestDome includes the proctoring that defends against a hidden AI assistant on every pack. HackerRank reserves that proctoring for its Pro plan. TestDome is also pay-per-candidate, with no subscription and no annual commitment. HackerRank stays the stronger fit if you hire developers at scale and depend on its deeper coding-only library or its wider integrations enough to justify the higher committed price. The place to look closely is the library. HackerRank goes deeper on pure coding, while TestDome adds non-coding tests HackerRank does not offer.

Which is cheaper, TestDome or HackerRank?

Once you require the AI-grade monitoring and lockdown, TestDome is lower at every candidate volume. The gap widens as you test more. At 300 candidates TestDome is $2,400 versus HackerRank's $4,490 annual. The one place HackerRank comes close is a single low-volume burst on its month-to-month plan, where the two prices land within about fifty dollars of each other. The thing to watch on HackerRank is its 25-candidate monthly cap, which is why its annual plan is usually the better buy for a concentrated hiring push.

Does TestDome test non-coding skills?

Yes. TestDome covers reasoning, attention to detail, teamwork, communication, MS Excel and Office, and business and finance roles. None of those are in HackerRank's developer-only library. TestDome carries 2,000+ questions across 130+ skills. For coding-only hiring, HackerRank's 7,000+ technical questions still go deeper on code.
