Are you allowed to open soda bottles on Shabbos?

Same as seltzer bottles.

Many poskim allow this. If you throw away the cap, it is allowed by even those who are otherwise machmir. I keep a collection of bottle caps in a drawer, which I use on Shabbos, and I throw the ones I remove on Shabbos into the trash.

I think there's a brand that has a cap specifically designed to be permitted on Shabbos.

What about opening soda cans? I personally don't, but I know some people do. Since it's always thrown out after one use, is it better or worse?

Opening soda cans is a much more complicated Shaila thats why I recommend you should rather use Seltzer cans.

Why are seltzer cans better than soda cans?

Oh, I get it. I totally agree. (I prefer seltzer to soda altogether.)
