QuizOxide — Quiz API Built for Scale
The quiz API and assessment platform built with Rust.
Create quizzes on our dashboard or integrate the full quiz engine into your product via REST API. Designed for educators, enterprises, and developers who need an online assessment API and quiz backend that scales.
Currently in alpha — data may be reset as we refine the architecture.
A quiz platform for developers and teams
Most quiz platforms are built for casual use. QuizOxide is built for organizations that need reliable assessment infrastructure — whether you use our dashboard or embed the quiz engine API into your own product.
REST Quiz API Architecture
Every feature is exposed via REST API. Embed quiz creation, delivery, and scoring directly into your LMS, HR system, or educational portal. Issue API keys, manage participants programmatically, and let your platform handle the UX while QuizOxide handles the quiz engine.
Quiz Backend Built for Concurrency
Written in Rust with Actix-Web, not a Node.js or Python monolith. When thousands of participants start an exam at the same moment, QuizOxide stays responsive. Load-tested to handle 10,000 concurrent users without performance degradation.
Assessment Platform Access Control
Public quizzes for open participation. Shared quizzes with auto-generated access codes for classrooms. Private quizzes with credential-based authentication for certification exams and secure assessments. Choose the level that fits your use case.
Everything you need from an online assessment API
From question authoring to real-time monitoring, QuizOxide covers the full assessment lifecycle for modern quiz apps.
8 Question Types
Multiple choice, multiple select, true/false, fill-in-the-blank, short answer, ordering, matching pairs, and essay. All auto-evaluated except essay, with AI grading on the roadmap.
Rich Content Editor
Author questions with formatted text, LaTeX math equations, and structured content. The label/value system lets you update question wording without breaking answer keys.
Real-Time Monitoring
Watch participants progress through a quiz in real time via WebSocket feeds. Live leaderboards update as answers are submitted. Auto-submission enforces deadlines.
Assessment Analytics
Difficulty indexes, discrimination analysis, score distributions, and participant learning curves. Backed by TimescaleDB for time-series performance at scale.
Participant Management
Bulk import participants via CSV or API with custom metadata fields. Track attempts per participant, enforce max attempt limits, and map to external user IDs for integration with your existing systems.
Event Organization
Group quizzes into time-bounded events with ticketing. Compare participation rates and score distributions across events. Ideal for exam periods, training sessions, and competitions.
A quiz engine API for real-world integrations
Use QuizOxide standalone or plug it into your existing platform. The REST API gives you full control over every aspect of quiz delivery and evaluation.
Education
Campus-wide exams with shared access codes and real-time proctoring dashboards.
Enterprise
Employee onboarding, compliance training, and certification with private credential-based access.
SaaS Platforms
Embed quiz functionality into your product via REST API. White-label the assessment engine.
Government
Civil service exams and licensing tests with strict deadline enforcement and audit trails.
Launch a REST API for quizzes in minutes
Whether you use the dashboard or the API, getting a quiz live takes three steps.
Author Questions
Create questions with the rich text editor or via the API. Choose from 8 question types. Build a reusable question bank organized by category and tags.
Configure & Distribute
Set time limits, attempt caps, shuffling, and scheduling windows. Publish publicly, share with access codes, or restrict to pre-authorized participants with API keys.
Monitor & Analyze
Track progress via real-time WebSocket dashboards. Review analytics including difficulty indexes, score distributions, and participant performance trends after submission.
