Do I really need a firewall for my server? (sopuli.xyz)

I've been running my server without a firewall for quite some time now, I have a piped instance and snikket running on it. I've been meaning to get UFW on it but I've been too lazy to do so. Is it a necessary thing that I need to have or it's a huge security vulnerability? I can only SSH my server from only my local network and must use a VPN if I wanna SSH in outside so I'd say my server's pretty secure but not the furthest I could take it. Opinions please?

This is the best answer. Your router protects you from the outside, but a local firewall can protect you from someone prodding your lan from a hacked camera or some other IoT device. By having a firewall locally you just minimize the attack surface further.
