Host World-Class CTF Competitions
Engage your community with dynamic, scalable, and hands-on Capture the Flag events. Powered by our robust infrastructure, designed for seamless performance.
Built for Competition
Everything you need to run a successful CTF
Don't let infrastructure headaches ruin your event. CourseStack provides a battle-tested platform tailored for stability and fairness.
- Unique Infrastructure Per Player
Every participant gets their own dedicated environment. No more sharing instances or fighting for resources. Each player has a fresh, isolated challenge environment.
- Dynamic Flags
Eliminate cheating with dynamic flags generated uniquely for each player and team. Flag sharing becomes impossible when everyone hunts for a different hash.
- Completely Hosted
Forget about provisioning servers, configuring firewalls, or managing Docker containers. We handle the entire infrastructure so you can focus on the competition.
- Effortless Scaling
Whether you have 10 participants or 10,000+, our platform scales instantly to meet demand. Run massive events without worrying about infrastructure limits.
