Examination Center vs Codio
Codio is a cloud coding platform built for teaching, courseware, and auto-graded assessments, while Examination Center is built for one job: running fair, AI-free coding exams and giving instructors integrity evidence to review.
Examination Center is in early access — we're onboarding institutions through our Early Access Program. The information here describes our current platform and direction and may evolve; it is not a contractual commitment.
Key differences
| Examination Center | Codio | |
|---|---|---|
| Primary purpose | Purpose-built for secure coding exams | Designed as a cloud IDE and courseware/teaching platform |
| AI-free exam environment | Plain editor with no built-in AI assistant and no autocomplete, identical for every student | Typically includes coding-assistance and IDE conveniences aimed at learning |
| Integrity signals | Live monitoring plus paste, large/sudden edit, and cross-student similarity shown as evidence for human review | Focused on assessment and feedback rather than live exam-integrity evidence |
| Grading | Does not grade or keep a grade book by design; academic judgment stays with the instructor | Includes auto-grading and assessment scoring as a core feature |
| Autosave and recovery | Autosave plus session recovery so a frozen or closed browser never loses work | Cloud-based workspaces that persist student work |
| Languages today | Python in the browser (NumPy, pandas, Matplotlib) plus C, C++, Fortran, and Java in a secure server sandbox | Broad multi-language support across its courseware platform |
| Setup for students | Browser-based, nothing to install | Browser-based, nothing to install |
| Scope | Focused exam tool; not an LMS or full courseware suite | Broader platform spanning content authoring, learning, and assessment |
When to choose Examination Center
Choose Examination Center when your goal is a controlled, AI-free exam with integrity evidence you review yourself, rather than a full teaching-and-courseware platform. If you need to author curriculum and auto-grade coursework day to day, Codio fits that broader job, and Examination Center can handle the exam itself.

FAQ
Is Examination Center a Codio alternative?
For the exam itself, yes. If you want a focused, AI-free environment to run and monitor coding exams with integrity evidence for human review, Examination Center is a strong alternative. If you also need full courseware authoring and a teaching platform, Codio covers a broader job and the two can be used together.
Does Examination Center grade or auto-grade?
No. Examination Center does not grade, score, or keep a grade book by design. It secures the exam and surfaces integrity evidence; academic judgment stays with the instructor. You can export the code and grade it in your existing workflow.
Which languages are supported?
Today Python runs in the browser via Pyodide with NumPy, pandas, and Matplotlib, and C, C++, Fortran, and Java compile and run in a secure server sandbox. More languages are planned.
Does it have a built-in AI assistant or autocomplete?
No. The exam editor has no built-in AI assistant and no autocomplete, and it is identical for every student so the exam stays fair.
Is it a lockdown or proctoring browser?
No. Examination Center does not take over, lock, or record the student's device or camera. It is a browser-based exam environment with live instructor monitoring and integrity evidence for human review.
What happens if a student's browser freezes or closes?
Autosave and session recovery mean work is preserved. A student can return after a frozen or closed browser and pick up where they left off, so a technical hiccup doesn't cost them their answers.
