Adaface sells credits by the year, charges some of them to set a test up, and lets the rest expire twelve months after purchase. What you get for them is a 500+ test library of short, scenario-based tests delivered through a chat interface. TunnelQuiz has no library. It bills monthly or yearly, charges nothing to build a test, and captures the candidate's whole screen every minute, with webcam snapshots and a live list of every candidate's progress and flags from Essential.
Every Adaface plan is annual, from $180 a year for 12 credits to $50,000 for unlimited, and its pricing FAQ says credits expire one year after purchase. Setting up a ready-made test also costs 5 credits, and a custom test 10. TunnelQuiz bills monthly or yearly, the Free plan adds 50 credits each month, and there is no charge to create a test: a credit is spent only when a candidate sits it.
With screen proctoring on, Adaface asks the candidate to share their screen and captures a screenshot when they leave the test window. TunnelQuiz captures the entire shared screen every 60 seconds and each time the candidate returns, on every plan. It also flags a second display in Chrome and Edge and, from Essential, known AI-assistant browser extensions.
Adaface lists 500+ tests across programming in 35+ languages, 100+ aptitude tests, personality, typing and five languages, and says it checks every month that ChatGPT can't solve its questions. TunnelQuiz ships no tests. You write your own, import a CSV, or generate questions with AI on Pro. That is more work up front.

Plenty of teams already have a question bank: last year's placement paper, an internal certification, a product quiz. TunnelQuiz imports it from a CSV and adds random pools, negative marking and per-question timers on every plan, so the questions stay yours.

Adaface shows its captures on the scorecard after the test. TunnelQuiz's live monitoring, from Essential, lists every candidate with progress and flags as they arrive, and the full-screen captures are there to open while the sitting is still running.

If you write your own questions, yes. TunnelQuiz bills monthly, has a recurring free plan, charges nothing to set up a test and captures the whole screen on every plan. If you want ready-made, validated tests for programming, aptitude or personality, Adaface's 500+ test library is something TunnelQuiz doesn't have.
As of October 2026, Adaface's pricing page lists annual plans only: Individual $180 (12 credits), Starter $500 (50), Pro $900 (100), Scale $3,000 (500), Growth $5,500 (1,000), Enterprise $20,000 (5,000) and Unlimited $50,000. A library test costs 5 credits to set up and a custom test 10, each candidate invite costs 1 credit and is refunded if unused, and credits expire one year after purchase. There is a 14-day free trial.
As of October 2026, TunnelQuiz has four plans: Free ($0, 50 credits a month that lapse at month end), Essential ($34 a month billed yearly, 150 credits a month), Pro ($87 a month billed yearly, 250 credits and 10 AI credits a month) and Business (quoted). Monthly billing is also available. Prices are in US dollars with no tax added. In India the same plans are ₹1,319 and ₹3,519 a month billed yearly, plus 18% GST.
Adaface's pricing page shows the same dollar plans with no rupee option, though it has an office in Bengaluru. TunnelQuiz sells in rupees in India, at ₹1,319 a month billed yearly for Essential plus 18% GST, and has a free plan with 50 credits every month.
They cover different ground. Adaface leans on its questions: it says they are written in-house, checked monthly against ChatGPT, and replaced when crawlers find them leaked. TunnelQuiz leans on the session: whole-screen captures every minute on every plan, second-display detection, and from Essential webcam snapshots, AI browser-extension flags and live monitoring.
Start on the free plan with 50 credits every month. No credits to set up a test, and monthly billing on paid plans.
