Agar-agar is halal. It is a gelling agent made entirely from seaweed (red algae), with no animal ingredients — the plant-based alternative to gelatin. All schools consider it permissible, and it is widely used in halal, vegan and vegetarian foods.

The short version
Agar-agar is a plant gelling agent from seaweed — a halal, vegetarian alternative to gelatin, with no animal-source question.
What it is and where it's used
Made from red algae (seaweed), agar sets liquids the way gelatin does but is entirely plant-based. It appears in desserts, jellies and some dairy, and is the go-to gelatin substitute in halal baking.
Why it's straightforwardly halal
There is no animal, alcohol or slaughter question — it is seaweed. That is exactly why it is a standard halal and vegan replacement for gelatin.
