How to Befriend Everyone in Undertale
To befriend everyone in Undertale, go for the Pacifist Route! Don't kill any monsters. Instead, use the Act menu to interact with them and then spare them. Also, make sure to hang out with Papyrus and Undyne, and visit Alphys to complete her lab's True Lab quest. Enjoy the heartfelt ending!

Just don't hurt anybody. Use the Act menu and always choose to spare the enemies in battle. You'll be everyone's friend in no time!
I did the True Pacifist run, and it worked like a charm! No fighting at all. Engage with the characters, and follow the hidden questlines. Trust me, it's worth it for the ending!
Hot take: skip the Neutral and Genocide runs. Go straight for the Pacifist route. Best experience for making friends!
