Improve your workflow in Unity

What is Odin?

Odin Inspector is a plugin for Unity that lets you enjoy all the workflow benefits of having a powerful, customized and user-friendly editor, without ever having to write a single line of custom editor code.

Instead of writing and maintaining thousands of lines of custom editor code, developers can annotate their data structures with our 100+ building block attributes to quickly and easily build user-friendly editors for their entire team.

Odin is additionally packed to the brim with a broad suite of editor utilities for many common tasks like creating custom editor windows and much, much more.


If I had to bring one tool with me to a deserted island it would be Odin. This editor extension takes the Inspector to a whole new level. A must have for any Unity programmer.

More than 100 new Attributes

Odin has more than 100 new high-quality attributes that let you create powerful and user-friendly editors with little to no effort.

All of Odin's attributes work right out of the box; there is no need to inherit from any base class, Odin Inspector works right off the bat, you can even make editor windows just using attributes.

You can find an online overview of all of Odin Inspectors attributes here:

Custom Editor Windows

Whether it is to get an overview of data, allow access to large sets of common data, or even to create custom tooling, making editor windows can go a long way to ease and streamline the production workflow of a project. However, it can be a pain to keep them maintained and relevant as the project changes.

This is where Odin Editor Windows come in. By merely inheriting from a single class you access to the powerful Odin drawing system in its entirety. You no longer have to worry about how your windows are drawn, but can instead focus on what is actually important: the function they should provide.

Odin Project Validator

Paid addon

Making sure everyone on your team sets up your data correctly when working directly with assets is made easy using the live input validation features that Odin Inspector provides. However, sometimes, warning messages get ignored, assets get deleted, requirements change, and data is made obsolete as your project grows. Slowly bugs, errors, and faulty data creep in as work progresses. Manually going through your entire project to find and correct issues can quickly grow to be an insurmountable task.

Using the Odin Project Validator, you can easily scan your entire project for warnings and errors, and fix them inline right from the validator. The validator handles scene switching and saving as you work, letting you quickly and freely navigate between all issues with no hassle and no delay.

Serialize Anything

Odin Serializer is a powerful, flexible, extendible and open source serializer built from the ground up and maintained by Sirenix for Odin Inspector.

A simple, straightforward data structure is often the way best way to go, but there are times when you just need to serialize that complex generic, polymorphic type with cyclic references and edit it in the inspector. This is where our custom serialization protocol comes into play, as it is capable of serializing virtually anything.

We firmly believe that the Odin Serializer is the best serializer available for Unity.
