Mercer | Mettl is a full assessment suite: psychometric and aptitude tests, coding simulators, a test library, an exam platform, and a proctoring service that mixes AI flags with live human proctors, a secure browser and a second camera. It is built for universities, exam bodies and large employers, and its prices come by quote. TunnelQuiz is smaller and self-serve. You sign up, build a proctored test and send the link the same day, on plans priced in rupees with a free tier. If you need human proctors or photo ID checks, Mettl has them and TunnelQuiz doesn't.
Mettl has a free trial, but parts of its proctoring run through its team. Live and record-and-review proctoring are switched on by emailing Mettl, and the apps its secure browser allows are configured per test link on request. On TunnelQuiz every proctoring setting sits in the test editor: create a test, pick its checks, share the link.
Mettl's pricing page offers a "customised plan as per your organisation", a sales number and a quote form. TunnelQuiz lists every self-serve plan, the credits each one includes and the top-up price on its pricing page, and the Free plan gives you 50 credits a month to try it on real candidates.
Mettl sells psychometric, behavioral, aptitude, coding and communication assessments, plus 360-degree feedback and hackathon tools. If you mostly run MCQ and written-answer screening tests, TunnelQuiz covers that with far less to set up. If you need validated psychometric tests, Mettl is the better fit.

Create a test, set the pass mark and the proctoring, share one link. There is no secure browser to configure and no human proctoring to schedule, which also means no human proctor in the room. For most screening tests that is the right trade.
What there is to set up
Mettl Secure Browser for lockdown; human proctoring enabled on request
No secure browser to configure, and no human proctor either
Mettl reports 200,000 concurrent assessments in one day and more than 2,000 proctors deployed in a day. TunnelQuiz isn't pitching that. It is built for hiring teams and institutions that run their own drives and buy credits as they go.

Mettl's AI proctoring is on in every proctoring mode, and Mettl can add live human proctors or a record-and-review service, photo ID checks by its proctors, a lockdown browser and a phone as a second camera. TunnelQuiz runs in the browser with no human proctors. It captures the whole screen every minute, logs tab switches, blocks copy and paste and checks for a second display on every plan, adds webcam snapshots, noise detection and AI-extension detection from Essential, and gives you a risk score with an optional auto-terminate. It doesn't check photo IDs or match faces.
TunnelQuiz, for a typical screening test: sign up, build the test and share the link the same day. Mettl offers a free trial too, but live or record-and-review proctoring is enabled by emailing Mettl, and secure-browser allowlists are set up on request.
Yes. Written answers are marked by you by default. On Pro, AI can draft the marks for you to review, and they only become final if you turn that on.

For national-scale exams with human invigilation, Mettl is built for that: it reports 200,000 concurrent assessments in a single day.
