longbook is licensed under **GPL-3.0**. Codebase access is currently by request, for developers helping to make longbook stable — bug fixes, hardening, and building on top of it.

HOW ACCESS WORKS

An email to [contact@longbook.app](mailto:contact@longbook.app?subject=Source%20access%20request), sent from the registered email address the longbook purchase was made with, carrying two details:

**1.** A GitHub username or profile link.
**2.** The reason for access — the intended work.

A repository invitation follows.

The work is coordinated on the [community Discord](https://discord.gg/28Dtvbx23q) — feature requests, the roadmap, and who is building what.
