TestDome vs TestGorilla: Pay-Per-Candidate vs Annual, Compared for Developer Hiring

In one line: for developer hiring, pick TestDome, since a 2026 developer screening step has to stop a hidden AI assistant and TestGorilla cannot. TestGorilla fits the different job of screening broadly across non-technical roles.

TestDome and TestGorilla are both established tools for testing candidates before you hire them, but they are built for different jobs. The sharpest difference for developer hiring in 2026 is integrity. TestDome locks down the test environment to block a hidden AI assistant from running on the test machine. TestGorilla stays at the browser level, so its monitoring cannot see an invisible overlay assistant (a window only the candidate can see) running outside the browser.

Key points

  • Anti-cheating is TestDome's clear lead: TestDome locks the test environment and runs AI-analysed monitoring with every pack. TestGorilla monitors browser behavior with webcam snapshots, but it does not lock the machine and cannot see a hidden AI assistant running outside the browser.
  • Commitment and price: TestDome is pay-per-candidate from $100 for 5 candidates, and packs never expire. TestGorilla sells annual plans (Core $1,620/yr self-serve, developer-grade Plus from $4,800/yr contact-sales), shown as a monthly figure that is really a 12-month contract.
  • They lead on different library axes: both cover skills testing across coding and non-coding roles, but TestGorilla adds personality, culture-fit, cognitive-ability, and language testing that TestDome does not offer. TestDome goes deeper on job-relevant work-sample tasks, with 2,000+ questions across 130+ skills, and is stronger for developer roles.

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 TestGorilla's own published pages, and we link them so you can check each one. Where TestGorilla 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, the things a developer screening step fails without:

  • It has to stop a candidate using a hidden AI assistant.
  • It has to predict real performance through job-relevant tasks that cover your roles.
  • Its cost and commitment shape have to fit how you actually buy.

Then we cover the nice-to-haves where the two differ: how each measures AI skill, formal ID verification, and non-technical breadth.

What does each cost, and how do you commit?

TestDome is pay-per-candidate, from $100 for 5 candidates with no contract. TestGorilla sells annual plans: Core at $1,620 a year and the developer-grade Plus from $4,800 a year, contact-sales. At the volumes most teams hire, 100 to 600 candidates, TestDome costs $1,000 to $4,200, below Plus's $4,800 starting point. Every TestGorilla figure below carries one caveat. No TestGorilla plan includes a lockdown against a hidden AI assistant, so the prices only matter once you decide that gap is acceptable for your roles.

TestGorilla's cheaper Core plan ($1,620/yr, self-serve) is limited to lighter multiple-choice screening. It leaves out ATS and API integration (to plug into your applicant-tracking system) and the richer coding challenges. That makes Core fine for non-technical hiring but not enough for a developer screening step. The gap pushes most developer teams to Plus, and Plus is where the pricing turns opaque. Plus is contact-sales, quoted from $4,800 a year, with credit amounts customized per deal and no published credit count. What $4,800 buys in candidates is settled on a sales call. Both paid plans are shown as a monthly figure ($135 and $400 a month) that is really a 12-month commitment. Several reviewers report signing up believing they were month-to-month and later finding a yearlong contract. Confirm current figures for your region on TestGorilla's pricing page. Every TestDome price below includes AI-grade proctoring (AI-analysed monitoring plus a locked-down test environment).

Candidates tested/year Roughly the hiring of (varies by funnel) TestDome (AI-grade proctoring included) TestGorilla Plus (contact-sales, browser-level monitoring, no machine-level lockdown in its published feature set)
25 a startup filling a role or two $400 from $4,800/yr, credits by quote
100 a small team $1,000 from $4,800/yr, credits by quote
300 a growing company $2,400 from $4,800/yr, credits by quote
600 a large team $4,200 from $4,800/yr, credits by quote
2,000 high-volume hiring $12,000 custom quote, scales with volume

The table compares against Plus because Plus is the plan a developer screening step needs. If your hiring is mostly non-technical, Core at $1,620/yr self-serve is the fairer comparator.

Beyond the list price, the two pricing models differ in two ways that favor an occasional hirer. TestGorilla's credits are an annual allowance. Unused credits lapse, and a busier hiring year means moving up to a bigger plan. TestDome's packs are prepaid and never expire, so nothing is lost if a hiring push slips into next quarter. And TestDome does not gate features by pack. Every pack includes the proctoring, ATS integrations, API access, and multi-user access, so the cheapest pack is still the full product.

How does each stop a hidden AI assistant?

Stopping a hidden AI assistant takes locking down the test environment, not just watching browser behavior. TestDome locks it down with every pack. Its Safe Exam Browser shuts down disallowed processes, so an AI assistant cannot run on the test machine. TestGorilla monitors browser behavior and webcam snapshots but cannot see an overlay assistant running outside the browser.

The threat is an overlay assistant that feeds a candidate answers while staying out of view. TestDome defends against that threat with every pack, from the first candidate. Safe Exam Browser locks the test machine and shuts down disallowed processes. That blocks a local AI assistant from running. AI-analysed screen recording flags tools like ChatGPT or DevTools inside the environment the candidate is allowed to use. 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. An overlay assistant fed from a separate device, including a fully offline model running on that device, can get past a lockdown, because it runs outside the test machine's control. That gap is why the screen and webcam layers matter. They flag the anomalies that the lockdown cannot physically block. TestDome also lets you assess unaided skill separately, so the score does not rest on the lockdown alone.

TestGorilla works on a different principle. It watches browser behavior (disabled copy-paste, tab-switch and full-screen monitoring, webcam snapshots) and flags outliers. Those controls catch a candidate leaving the test window or pasting an answer, and they are useful against ordinary cheating. But an overlay assistant runs outside the browser and shows answers on screen without any tab switch or paste. Browser-behavior monitoring cannot see that activity, and TestGorilla does not claim that it can. For the 2026 buyer whose specific worry is a candidate using a hidden AI assistant, that blind spot is the decisive point.

How does each measure AI skill?

Both measure AI skill, but they report it differently. TestDome runs dedicated AI-skills tests and scores unaided domain skill separately from AI skill. TestGorilla measures "AI fluency" blended into the overall screening, with no separate AI-skill result. Its auto-scored AI video interviews are a separate format in which the AI sits on the employer's side, conducting the interview.

Working with AI is now part of the job, so how a candidate uses AI belongs in your screening. TestGorilla folds that measurement into its AI-fluency assessment, giving you one blended signal on the candidate. Its AI video interviews are a different tool: there the AI conducts the interview for the employer, which is not a measure of how the candidate works with AI. TestDome splits the result. It runs dedicated AI-skills tests (from AI literacy to prompt and LLM engineering) and keeps them separate from its AI-free domain tests. A pass on the unaided part tells you the person can do the work themselves instead of just steering a good AI answer. Which approach you prefer depends on whether you want one blended signal or a separate view of unaided skill. The reasoning behind keeping the two apart is in our guide on assessing developers in the AI era. The same comparison applies against Codility and HackerRank if they are also on your shortlist.

Which has the better test library?

TestGorilla has the broader catalog: 350+ tests including personality and culture-fit that TestDome does not offer. TestDome goes deeper for the roles it covers, with 2,000+ work-sample questions across 130+ skills, and is stronger for developer coding. The two lead on opposite axes, so the honest answer depends on what you screen for.

TestDome's library is deliberately focused on depth and realism for the roles it covers. Its questions are built as work-sample tasks that mirror the actual work, with no trick questions, across 2,000+ questions and 130+ skills spanning coding and non-coding. Coverage is deep on mainstream developer and QA stacks. A few specialized areas are thinner. If you hire for a niche programming library or a less-common framework, check that the catalog covers your exact role before you commit.

TestGorilla's strength is breadth across non-technical hiring. Its catalog holds 350+ tests and spans skills, cognitive ability, personality, culture-fit, and language. That coverage is what a team hiring across sales, support, operations, and other non-engineering roles wants in one place. TestDome does not offer personality, culture-fit, standalone cognitive-ability, or language testing, so for that mix TestGorilla is the wider choice. None of that catalog runs under a lockdown, though, so the breadth helps most on roles where AI cheating is not the deciding risk.

For developer hiring, the difference shows in the test format. TestGorilla assesses coding through its skills-test library, which relies on multiple-choice and short answers. Its richer coding challenges and job simulations are reserved for the higher Plus plan. TestDome's coding tests are work-sample tasks with every pack, so you get a realistic coding exercise without stepping up a tier.

When is TestGorilla the better choice?

  • You screen across many non-technical roles and want skills, personality, and culture-fit tests in one broad catalog.
  • You want built-in talent-sourcing access to a candidate pool alongside your tests.
  • You need formal government-ID verification, which TestGorilla gates to the Plus plan, and you are on Plus or willing to buy it. A document check confirms the ID. It cannot tell you whether a live deepfake or a synthetic identity is in use, so treat ID verification as a useful extra rather than as an AI-cheating control.
  • You hire steadily year-round, so an annual commitment is a fair trade for the broad library.

One caveat applies to all four reasons. If unsupervised AI use is a real risk in your process, TestGorilla's browser-level controls do not address it, whatever the breadth.

If you are leaning the other way, TestDome makes it easy to try before you commit. It is self-serve and pay-per-candidate, so you can run a real work-sample test on a handful of candidates for the price of a starter pack. There is no sales call and no yearlong contract to sign first.

TestDome vs TestGorilla FAQ

Is TestDome a good TestGorilla alternative?

Yes, with one thing to check first. TestDome is pay-per-candidate with no subscription and no annual commitment, and its packs never expire. You pay only for candidates you actually test and keep anything unused. TestGorilla's paid plans are 12-month commitments shown as a monthly figure. The thing to check is what you would give up. TestDome does not offer TestGorilla's personality and culture-fit testing. If your hiring leans on those test types, TestGorilla is still the better fit. If you mainly screen developers and want to avoid a yearlong contract, the pay-per-candidate model is the reason to switch.

Which is cheaper, TestDome or TestGorilla?

For developer hiring, TestDome is cheaper at the volumes most teams run. A developer screening step needs TestGorilla's Plus plan (Core omits ATS/API integration and the richer coding challenges), and Plus is contact-sales from $4,800 a year. TestDome is $1,000 at 100 candidates, $2,400 at 300, and $4,200 at 600, with nothing committed up front. TestGorilla's Core plan ($1,620/yr) can be cheaper if lighter multiple-choice screening without integrations is enough for you. Core still has no lockdown against a hidden AI assistant, though.

Can TestGorilla detect ChatGPT or catch AI use during a test?

Partly. TestGorilla's monitoring flags behavior like tab-switching, pasting, or leaving the test window, which can catch a candidate copying from a chatbot in another tab. TestGorilla does not run a machine-level lockdown that terminates disallowed processes. So it cannot stop or see an invisible overlay assistant like Cluely or Interview Coder that runs outside the browser and shows answers on screen. TestDome blocks that class of tool by locking the test environment, included with every pack.

Does TestGorilla have more tests than TestDome?

For non-technical roles, yes. TestGorilla's 350+ catalog is broader and adds personality and culture-fit testing that TestDome does not offer. TestDome has 2,000+ questions across 130+ skills, built as work-sample tasks, and goes deeper for the roles it covers, especially developer roles. Which matters more depends on what you hire for.

Is TestDome or TestGorilla better for hiring developers?

TestDome, for most teams. Its coding tests are work-sample tasks with every pack, and its lockdown blocks a hidden AI assistant from running on the test machine. TestGorilla can test coding, but its richer coding challenges sit on the Plus plan, and its integrity controls stop at browser-behavior monitoring without a lockdown. TestGorilla wins here only if developer roles are a small part of a much wider non-technical hiring mix.
