Why I’m Open Sourcing Zotto
I’ve decided to open source Zotto.
Zotto began as a way to bring AI-assisted development tools to Xojo developers. I built it because I cared about the Xojo community, and because I thought there was real value in giving developers a faster, more capable way to work with their projects.
A lot has changed since then.
My full focus now is on Objo Studio, an IDE for building cross-platform applications. It's where my time, energy, and long-term development work are going. Objo Studio also has its own deeply integrated AI assistant, and that integration gives it capabilities that Zotto could never realistically match as an external companion tool.
That creates an obvious problem.
Zotto is a powerful tool built for Xojo, and Xojo is now directly adjacent to what I’m building with Objo Studio. Continuing to sell a commercial tool for a competing development environment no longer feels appropriate. It would split my focus, create a conflict of interest, and ultimately be unfair to users who deserve clarity about where my attention is going.
At the same time, I do not want to simply shut Zotto down.
The Xojo community has been kind, supportive, and generous to me. Many people bought licenses, gave feedback, reported bugs, suggested improvements, and helped shape the app. I’m grateful for that. Just cutting off access or leaving the app to quietly disappear would not sit right with me.
So I’m open sourcing the entire application.
This means Zotto will no longer be a commercial product, but it will remain available. Existing users can continue to use it, developers can inspect the code, and anyone interested can adapt, maintain, or extend it. If the community finds value in keeping it alive, the source will be there.
I think this is the cleanest and fairest outcome.
It lets me be honest about where my focus is now, while also respecting the people who supported Zotto. It removes the commercial conflict, preserves the work that went into the app, and gives Xojo users the best chance of continuing to benefit from it.
Thank you to everyone who supported Zotto. I genuinely appreciate it.
I hope making the app open source is a useful final chapter for the project, and a fair way to hand it back to the community that made it worthwhile.
