About
Networks are fascinating. Learning them shouldn't be painful.
Packet.School exists because the best networking resources are dense, expensive, or English-only. We're fixing that — one simulation at a time.
01
Simulations, not slides
You don't learn to drive by reading a manual. You don't learn networking by reading about TCP. Watch packets move. Break things. Understand why.
02
Bottom-up, always
We start with voltage on a wire. Every abstraction we add was earned. When you reach BGP, you'll already know why it has to exist.
03
Free. Forever.
MIT licensed. No paywall. No free trial. Every lesson, simulation, and certificate is free for individuals — permanently. That's the deal.
Open source from day one.
Course content, simulations, the entire platform — MIT licensed and on GitHub. Build on it. Fork it. Improve it.
