[Request] Chili/chilli sauce to use?

In checking out Indian and Malay recipes, I see "chilli sauce" or "chili sauce" referenced. I'm assuming this is not the Heinz stuff in the ketchup aisle, but I don't know if there's a bottled version I can buy somewhere, or whether I make my own.

I'm also assuming that the Indian and Malaysian versions aren't the same, so I don't know how to search and determine specifically what they're using.

Thanks for any help.
