Nezumo is now open source

Nezumo is opening up

Today we are opening the Nezumo source code. You can now see how the product works, build it locally, explore individual components, propose a change, or use the work in your own projects under the terms of its license.

The main repository is available on GitHub at OctaHive/nezumo.

What is open

Nezumo is more than the board interface. We are publishing the complete product ecosystem:

• The browser application, built with React and TypeScript.
• The Rust canvas engine, including the board model, collaborative state, tools, and GPU rendering.
• The desktop client and native renderer.
• The Nezumo backend, including the API, authentication, real-time collaboration, file storage, and board export, in OctaHive/nezumo-server.
• This website and changelog, in OctaHive/nezumo-web.

The main repository also includes documentation for building the browser application, WebAssembly runtime, desktop client, and native renderer.

Why we are doing this

We want Nezumo to evolve in the open. Source access makes it possible to understand the architecture, review implementation decisions, report problems, and propose improvements through pull requests.

It is another way to build the product together with the people who use it. Ideas from community discussions can now become not only feature requests, but concrete improvements to the code and documentation.

License

The main Nezumo code is licensed under the GNU Affero General Public License v3.0 only (AGPL-3.0). It allows anyone to use, study, modify, and distribute the project while following its terms, including the source-code obligations for modified versions offered over a network.

A separately negotiated commercial license is available for proprietary use under alternative terms.

How to take part

• Visit the main Nezumo repository and give it a star if you find the project useful.
• Read the README and build guide.
• Open issues for bugs and ideas.
• Send pull requests with fixes, improvements, and documentation.

Nezumo remains a ready-to-use cloud product that requires no self-hosting. Open source gives additional freedom to people who want to look inside, contribute to development, or run their own build.
