Supports 13+ languages & frameworks
Focus on what matters — teaching and learning code.
Share a 6-digit access code and students start coding instantly. No Docker, no VMs, no installs — environments spin up automatically with the framework you choose.
Live WebSocket-powered dashboard showing every student's status, deployment progress, and remaining time. Attention alerts flag failed deployments and students running low on time.
Create multiple timed modules per session. Pause, extend, or stop individual students. Auto-start modules with countdowns, and flag late submissions automatically.
Built-in marking rooms for judges and teachers. Grade with Pass, Partial, or Fail. Support for both in-person evaluation and remote marking teams across locations.
Toggle internet access per student for fair exam and competition environments. Available on on-premises deployments with full network-level DNS/DHCP control.
Every push deploys instantly to a live preview URL. Each student gets their own Git repo and MySQL or PostgreSQL database — completely sandboxed and always accessible.
Two-way messaging between students and teachers during active sessions. Answer questions, share hints, or send announcements without leaving the platform.
Lock or unlock Git access, clean repositories, extend individual time, and organize students into groups. Full control over every competitor from one dashboard.
Laravel, React, Vue, Angular, Next.js, Svelte, Django, Java, .NET, and more. Upload your own custom frameworks as ZIP packages — available across all sessions.
From zero to a full classroom of coders in minutes.
Pick a framework, set a time limit, and add your modules with instructions and deadlines.

Run hands-on coding exercises during class. Every student starts from the same template with their own isolated environment. No more "it works on my machine" problems.
Assign projects students can work on from anywhere. Set deadlines, track commits, and review code through Git history. Auto-deploy on push means instant results.
Run fair, timed competitions with internet controls. Live judging dashboards, isolated environments, and real-time monitoring keep everything transparent.
From daily classroom use to international programming contests.
"Before NStrim, half the class was wasted on environment setup. Now I create a session, students join, and everyone is coding in the first minute."
