TunnelQuiz vs CodeSignal: Compare Assessment Features & Pricing
CodeSignal is a specialized platform for evaluating software engineering candidates through live coding, IDE-based challenges, and keystroke replay, sold on credit-based plans with its top tier custom-priced. 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 identity checks and monitoring. If your hiring or exam process is code-heavy, CodeSignal is purpose-built for that; TunnelQuiz supports coding-answer grading on the Pro plan, but it does not provide CodeSignal's dedicated IDE-based coding assessment environment.
02
Published plans vs. custom enterprise pricing
CodeSignal publishes Build and Grow plans for technical hiring, with pricing based on billing frequency and included credits. Its Pro plan is custom-priced. TunnelQuiz also publishes its plan prices and monthly credit allowances, making it easier to compare entry-level costs before choosing a platform.
03
Self-serve setup vs. a sales-led rollout
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.

Reason 02
Right-sized for exams that aren't code-specific
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.

Frequently asked questions
Is TunnelQuiz a good alternative to CodeSignal?
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 an IDE or run candidates' code. 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.
Does CodeSignal publish its pricing?
Partly. CodeSignal publishes its Build plan ($99/month billed monthly or $79/month billed annually) and Grow plan ($599/month billed monthly or $479/month billed annually), while Pro is custom-priced. B2B pricing intelligence platform Vendr reports that the cost of custom deals 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.
How much does TunnelQuiz cost?
TunnelQuiz offers a Free Forever plan with 50 credits per month, Essential at $39/month or $34/month billed yearly with 150 credits per month, Pro at $99/month or $87/month billed yearly with 250 credits per month, and custom-priced Business plans. Unused Free plan credits expire at month-end, while paid-plan credits roll over while the subscription remains active. 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.
Does CodeSignal offer proctoring?
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 checks).
What is CodeSignal's "flight simulator"?
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.
Does TunnelQuiz support coding questions?
TunnelQuiz supports coding answers with AI grading on the Pro plan, in 19 languages, alongside multiple-choice and written-answer assessments. The code is not run, and it does not offer CodeSignal's dedicated IDE-based coding environment for live coding challenges.
Which platform integrates with an ATS?
TunnelQuiz offers webhooks into ATS and HR systems on its Business plan. CodeSignal offers basic ATS integrations on Grow and enterprise ATS integrations on Pro. Compare the integration requirements and plan costs for your hiring workflow.
Is TunnelQuiz cheaper than CodeSignal?
For MCQ or written-answer testing specifically, yes - TunnelQuiz's published plans start at $34/month billed yearly for 150 credits a month, with no sales call required, versus CodeSignal's Build plan at $79/month billed annually for 60 credits a year. 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.
