I was on a trip with my friends and we wanted to play codenames, it wasn't impossible to balance the board on my lap so I looked for a simple generator. And I couldn't find a single one that works, others just generate the grid or secret. So here I am, making one:
https://codenames-generator-bay.vercel.app/ps: it's local first, so you just need to go to the site once, next time it will load without internet. Hope it help with the bad internet on the road.
