CodeSignal is a specialized platform for evaluating software engineering candidates through live coding, IDE-based challenges, and keystroke replay, sold on custom, quote-only pricing. TunnelQuiz is a proctored MCQ and written-answer testing platform with published pricing, built for hiring, certification, and classroom exams that aren't code-specific.
CodeSignal's strength is evaluating code, IDE environments, a 4,000+ question coding library, and a "flight simulator" full-stack environment for realistic dev tasks. TunnelQuiz's strength is MCQ and written-answer testing with strong identity verification and monitoring. If your hiring or exam process is code-heavy, CodeSignal is purpose-built for that; TunnelQuiz isn't a coding-assessment tool.
B2B pricing intelligence firm Vendr confirms CodeSignal does not publish list pricing - cost depends on assessment volume, feature tier, and deployment model, negotiated per account. One listing puts enterprise pricing around $19,000/year. TunnelQuiz lists exact plans and credit allowances on its pricing page, plus a free plan with 50 credits a month.
CodeSignal is built and sold around enterprise technical hiring programs, with implementation, onboarding, and support tiers as part of the deal. TunnelQuiz is self-serve: create an account, build a test, share a link.

CodeSignal's pricing depends on assessment volume, feature tier, and deployment model — all negotiated per account. TunnelQuiz publishes every plan, so you can compare cost without a demo.

If you're screening for coding roles, CodeSignal's IDE and keystroke replay are purpose-built for that. If you're running hiring assessments, certification exams, or classroom tests that don't need a live coding environment, TunnelQuiz is scoped and priced for exactly that.
What the platform is built for
An IDE with keystroke replay
MCQ, written and short coding, proctored
TunnelQuiz publishes specific proctoring features, tab-switch alerts, second-screen detection, copy-paste blocking, face and email verification, on its features page. CodeSignal's public materials mention proctoring generally, without itemizing detection methods.

It depends on what you're testing for. CodeSignal is purpose-built for evaluating software engineering candidates through live coding challenges, IDE environments, and keystroke replay. TunnelQuiz is built for MCQ and written-answer testing, hiring screens, certification exams, and classroom tests, and does not offer coding-specific assessment tools. If your use case is code-heavy, CodeSignal is the closer fit; if it's general MCQ/written testing, TunnelQuiz is simpler and less expensive to start.
No. B2B pricing intelligence platform Vendr confirms CodeSignal does not publish list pricing; cost depends on assessment volume, feature tier, deployment model, and optional services like custom content development. One third-party listing cites enterprise pricing starting around $19,000/year, though figures vary by source.
TunnelQuiz has four plans: Free (₹0, 50 credits a month), Essential (₹1,499/month, 150 credits), Pro (₹3,999/month, 250 credits) and Business (quoted on volume), all exclusive of 18% GST. One credit is one candidate, one sitting, whatever proctoring the plan turns on; AI generation, grading and chat interviews are metered separately in AI credits.
CodeSignal's feature listings mention proctoring as part of its assessment suite, alongside automated grading and analytics, but public materials don't itemize specific detection methods the way TunnelQuiz's features page does (tab-switch alerts, second-screen detection, copy-paste blocking, identity verification).
It's a proprietary environment where candidates work inside a full-stack application, complete with databases, APIs, and a frontend layer, to demonstrate real-world development skills rather than isolated algorithm puzzles. TunnelQuiz does not offer coding-environment assessments.
Not currently. TunnelQuiz is built around multiple-choice and written-answer testing, graded by AI or a human reviewer. For live coding assessments, IDE-based challenges, or technical interviews, CodeSignal is the purpose-built option.
CodeSignal integrates with a wide range of ATS and HR platforms, including Greenhouse, Lever, Workday HCM, iCIMS, and Ashby. TunnelQuiz does not currently offer ATS integrations.
For MCQ or written-answer testing specifically, yes - TunnelQuiz's published plans start at ₹1,499/month with no sales call required, versus CodeSignal's fully custom, quote-based pricing. This isn't a fair comparison for coding-specific hiring, though, since CodeSignal offers assessment capabilities (live IDEs, keystroke replay) that TunnelQuiz doesn't provide at any price.
Published plans from ₹1,499/month. A free plan with 50 credits every month. No sales call required.
