Violet is a lightweight STUN/TURN server (RFC8489 and RFC8656) written in C without dependencies, based on libjuice.

"Mercy! Save us!" yelled Mrs Beauregarde. "[...] Violet, you’re turning violet, Violet!" [...]

"Squeeze her," said Mr Wonka. "We've got to squeeze the juice out of her immediately."
