Built to replace your stack

Stop stitching six tools together

Most hands-on training platforms stitch together an LMS, cloud infrastructure, browser access, payments, automation, and CTF tooling. CourseStack is one platform that does all of it — built from the ground up for technical training.

Today

A fragile, expensive stack

Course platform
Teachable, Thinkific, Kajabi
No labs. 5–10% fees on every sale.
Lab infrastructure
AWS, Hetzner, Proxmox, Vagrant
Cloud bills, DevOps time, custom provisioning scripts.
Browser access
Apache Guacamole, Kasm
Self-hosted. Your auth, TLS, and scaling to manage.
Payments + billing
Stripe + custom checkout
Stripe handles charges. You build everything else.
Automation glue
Zapier, custom scripts
Brittle webhook chains that break when one tool changes.
CTF infrastructure
CTFd, custom challenge hosting
Self-hosted CTFd plus VMs and containers per challenge.

Six bills. Six dashboards. DevOps time. Broken integrations when one tool changes.

The lab tech, built in

Hands-on infrastructure you'd build yourself — but don't have to

Browser-based VMs, multi-machine networks, custom images, and CTF infrastructure. All managed, all per-student, all included.

Browser-based VMs

Linux and Windows desktops streamed to any browser. No installs, no VPN setup for students.

Custom images

Bring your own VM images. Pre-install your tools, configurations, and vulnerable services.

Multi-machine networks

Build realistic lab networks with multiple VMs, isolated subnets, and routing.

Code workspaces & notebooks

Browser-based VS Code and Jupyter for scripting, exploitation, and data labs.

Student VPN access

Issue per-student VPN credentials for direct access into your training network when needed.

CTF challenge infra

Hosted challenge containers and VMs with start/stop control. Pair with scoreboards on the same platform.

Per-student environments, isolated by default

Every learner gets their own dedicated VMs and networks. No shared state, no “please don't break the lab for the next person.” Resets are instant. Custom images deploy in seconds.

0% transaction fees

Keep 100% of your course revenue

Other platforms take up to 5% of your revenue. We take 0%. You pay your Stripe fees, you keep everything else.

On $250K in annual course sales, that's up to $12,500 a year you keep instead of giving to a platform.

“Migrating to CourseStack has been a game changer. It has allowed us to deliver more engaging, secure, and technically advanced training programs with far less overhead.”

Eric Capuano

Co-Founder, Digital Defense Institute

“We were able to manage one single course before. Switching to this LMS has been a massive upgrade. We consolidated infrastructure, content, support, payments, quizzes, and course management into a single platform, eliminating the fragile web of third-party tools and manual custom (and costly) workflows we relied on before.”

Anthony Bendas

Co-Founder, Level Effect

“CourseStack has been an absolute game changer. We pride ourselves with offering practical, hands-on learning and education, and without CourseStack we wouldn't be able to deliver that at the size and scale that we do.”

John Hammond

Founder, Just Hacking Training

“So easy to get setup with a one-stop-shop for everything you need to deliver training. Easy for the instructor, and a great setup for the students. I couldn't ask for anything better.”

Tim Medin

CEO, Red Siege

“CourseStack brings an ease of use to training development and delivery that I have not previously seen matched. Their clear communication, quick updates to the platform, and feature rich environment make hosting training in CourseStack a breeze.”
