Gather all ingredients at room temperature for easier mixing.
In a mixing bowl, add the whole-egg mayonnaise and sweet chili sauce. Whisk them together until they are well blended and creamy.
Add the sriracha to the mixture. Adjust the amount to taste for spiciness.
Continue whisking until the sauce is completely smooth and all ingredients are well incorporated.
Taste your sauce and adjust any of the ingredients as needed.
If not using immediately, transfer the sauce to a storage container and refrigerate.
