The core Machete plugin is free and it will always be. Making a donation is not required in any way, but I would greatly appreciate it.

There’s no bit company behind it, just me, a single developer who initially created it to simplify his daily work.

All the proceedings from the donations are used to “book” my time or spent in the promotion of Machete. It also encourages me to keep up the work, so it’s your best way to ensure the continuity of the project.
