The Sovereign Developer
You don't owe the world your code. Open-source culture has a default: build something good, publish it, license it, answer the issues, keep it compatible forever. The Sovereign Developer asks the question that default skips: what does this developer actually gain by making this work public, and what do they give up to do it?
This is not an argument against open source. It's an argument against treating openness as the automatic answer for every project. Drawing on economics, law, and the realities of maintainer burnout, the book makes the case that keeping software private can be the better choice for a given developer, and if you've already published something that no longer serves you, it offers a framework for deciding what to do next.
For developers who have felt pressure to open-source something without ever weighing the cost, this book makes the case for the other option.

About the Book
The Sovereign Developer makes the economic and practical case that keeping software private is a legitimate default, not an exception a developer needs to apologize for. Open-source culture treats publishing as the natural endpoint of writing code, but visibility is not the same thing as obligation, and the question worth asking before a repository goes public is not whether open source is good, but what a specific developer gains by making this specific work public, and what they give up to do it. Drawing on economics (opportunity cost, transaction costs, the free-rider problem), software law (liability exposure under emerging regulations like the EU Cyber Resilience Act), and the lived experience of maintainer burnout, the book walks through when private, source-available, and hybrid licensing models actually serve a developer better than open collaboration, and when open source still makes sense. It also covers the practical mechanics: structuring a private engineering practice, managing risk if you do publish, and a decision framework for reassessing a project when the conditions that justified it have changed. The result is a clear-eyed, well-sourced argument for treating software privacy as a rational choice, not a retreat from community.
