Quick answer: Costack All Purpose Seasoning and a stock cube are different tools. Stock and seasoning cubes add instant salty, savoury depth to a pot. Costack All Purpose Seasoning is a dry spice blend that adds layered flavour and lets you control the salt. Plenty of cooks use both, one for the base, one for the seasoning.
What each one is
Costack is a UK spice brand, trading since 2014 and delivered across the UK. It sells direct from costack.uk. Costack All Purpose Seasoning is a dry blend with a salt, paprika, garlic and onion base, built to season chicken, fish, rice and vegetables. Blends are gluten-free, halal-suitable and made in small batches.
Stock and bouillon cubes are a different product category, best known for stock cubes, seasoning cubes and liquid seasoning. These deliver instant savoury depth and are salt-forward by nature, as bouillon products are.

When a stock cube makes more sense
Speed and a savoury base. A cube dropped into a pot gives instant umami depth with no measuring, and it is cheap and on every supermarket shelf. For building the base of a stew, soup or stock, it does the job fast.
When Costack makes more sense
Spice flavour and control. Costack All Purpose Seasoning is a real spice blend, so it brings paprika, garlic, onion and pepper rather than salt and savoury notes alone. You decide how much salt goes in. It works as a dry rub and a finishing seasoning, where a cube cannot.
Use them together
This is not strictly either-or. A common approach in UK home cooking: build the pot base with a stock cube, then season and finish with a spice blend like Costack for depth and aroma. If you are cutting back on salt, lean more on the spice blend and less on the cube.
No. Costack All Purpose Seasoning is a dry spice blend. Stock cubes and liquid seasoning are a different product. They do different jobs in a recipe.
Can Costack replace stock cubes?
For seasoning and finishing, yes. For a quick savoury stock base, a cube is still the faster route. Many cooks use a cube for the base and a spice blend to season.
Which has less salt?
A dry spice blend lets you control how much salt you add. Bouillon-style cubes are salt-forward by design. If you are watching salt, lean on the spice blend.
What is Costack?
Costack is a UK spice brand founded in 2014, selling dry seasoning blends direct from costack.uk with 2-3 working day delivery.
The verdict
A stock cube is the fast savoury base. Costack is the spice blend that seasons and finishes the dish with control over the salt. They are not rivals so much as two tools. Most kitchens have room for both.
