Run real code. In class. Right now.
BrainCraft's Live Terminal brings multiple containerized environments into your session Python, Node.js, Go, DevOps and more. No installs, no configuration, just code.
$ go run fibonacci.go
→ fib(10) = 55
→ fib(20) = 6765
$ nvim fibonacci.go
func fib(n int) int {
if n <= 1 { return n }
return fib(n-1) + fib(n-2)
}
Multiple environments, Neovim included
Python, Node.js, Go, Rust and more each environment ships with Neovim pre-configured for the selected language: LSP, autocompletion and syntax highlighting, out of the box.
No setup for anyone
The environment spins up on your slide. Participants interact through their browser.
Code live, get feedback
Combine a live terminal with MCQ or poll slides to check understanding of what you just demoed.
