3D aquarium and terrarium editor

The MOKIZEN editor is a free 3D editor in the browser for designing planted aquariums, terrariums and paludariums. You place plants, moss, stones, driftwood, lamps and fish in a glass tank, see them in real-time WebGL, and watch the planting grow over 90 days — nothing to install.

What can you do in the editor?

• Add items from a catalog of 806 plants, stones, wood, decor, corals, creatures and effects.
• Move, rotate and scale with a gizmo; objects settle onto the ground and are kept from clipping into each other.
• Group objects, name the groups, and hide or lock them from the Objects panel.
• Place lamps: each lamp casts its own beam and colours only the area under it, so several lamps can have different colours.
• Scrub the growth timeline to see the plants fill in over 90 days.
• Undo and redo, keyboard shortcuts, and touch controls on phones and tablets.

How do you start a tank?

1. Pick an empty tank, a curated world or a generated layout.
2. Set the tank size, shape and substrate.
3. Add the hardscape first — stones and wood — then plants from the back to the front.
4. Add lamps and fish, then save, share a link or export an image.

What can you export?

Images in Full HD (4K with Pro), video and GIF, a share link, the scene as JSON, a shopping list of every plant and stone you used, and an AR model to see the tank at real size through your phone.

Is the editor free?

Yes. A free account can place up to 60 objects per tank. Pro removes ads and the object limit and adds 4K and watermark-free exports.
