CodeVerse OS turns complex operating system concepts into real-time, interactive visual simulations. Explore processes, memory management, scheduling, and deadlocks hands-on.
Textbooks describe.
CodeVerse OS lets you live it.
Operating systems are taught as static diagrams and bullet points. But an OS is a living system — processes compete, memory fragments, deadlocks form. CodeVerse OS rebuilds these concepts as interactive simulations you can touch, watch, and break.
Every algorithm animates step-by-step so you see decisions happen.
Create your own processes, pages, and graphs — not canned examples.
Run multiple algorithms on the same input and compare metrics.
No fixed path. Explore freely, like a real operating system.
Ten systems. One machine.
Each module is a complete simulator with live animations, metrics, and algorithm comparison. Hover to preview, click to enter.
CPU Scheduling
Watch the dispatcher arbitrate the CPU. Compare scheduling algorithms with live Gantt charts and timing metrics.
Memory Management
Drag processes into RAM and watch fragmentation form in real time as the allocator hunts for the right hole.
Deadlock Simulator
Build a resource allocation graph and let the kernel walk it to find safe states, deadlocks, and recovery paths.
Disk Scheduling
Animate the read/write head sweeping across the platter and compare total seek time across strategies.
Virtual Memory
Follow a virtual address through the page table and TLB. See how the MMU translates and when it faults.
Page Replacement
Stream a reference string and watch frames evict pages. Count faults and compare eviction strategies.
File System Explorer
Navigate an interactive directory tree. Create, move, rename, and inspect inodes and permission bits.
Networking
Watch packets traverse switches and routers. Visualize latency, congestion, and packet drops on the wire.
System Call Explorer
Trace a process crossing the user–kernel boundary. Watch mode transitions and the syscall dispatch table.
Process Synchronization
Race conditions, mutexes, and the classic dining philosophers problem rendered as live concurrent actors.
Engineered like a real OS
Every interaction is considered — from the command palette to exportable results and full keyboard navigation.
Universal Search
⌘K command palette across every module and page.
Keyboard First
Every action reachable without a mouse. WCAG compliant.
Export Results
Save simulation outputs as PNG snapshots.
Replay Mode
Re-watch any simulation step-by-step after it runs.
Save Scenarios
Persist custom setups to local storage and reload anytime.
Achievements
Earn badges as you master each subsystem.
AI Assistant
Ask concepts in plain English and get visual answers.
Accessible
Reduced-motion support, semantic structure, focus rings.
From idea to deployment
The journey of building CodeVerse OS, phase by phase.
Idea
What if an OS taught itself? Reframe static textbook diagrams as a living, interactive machine.
Research
Study scheduling algorithms, memory allocation, and deadlock detection. Map each to a visual metaphor.
Planning
Architect ten modules, a shared simulation engine, and a consistent design language across all of them.
Design
Dark-first, glassmorphic UI inspired by Apple WWDC, Linear, and Arc. Inter, Space Grotesk, JetBrains Mono.
Development
Next.js + TypeScript + Tailwind. Framer Motion and GSAP for animation. Zustand for state. R3F for 3D.
Optimization
Tune animation performance, reduce re-renders, lazy-load heavy modules, and respect reduced motion.
Testing
Verify every algorithm produces correct metrics. Check edge cases: empty queues, single process, ties.
Deployment
Deploy to Vercel with optimized builds. Lighthouse-clean, responsive from mobile to ultra-wide.

No accounts. No setup. Just open a module and start exploring how computers really work.
