Overview

TweakInject loads dynamic libraries into running processes on macOS. A tweak is such a library plus a filter naming which processes it belongs in. These pages cover writing one, shipping it, and charging for it if you want to.

Start here

• Getting Started, a tweak that proves it loaded.
• Tweak Formats, bundles versus plain dynamic libraries.
• Filters, how targeting actually works.

Shipping it

• Packaging, building the .deb.
• Publishing, submitting to the store.
• Hosting a Repository, if you would rather not.

Selling it

• Paid Tweaks, price tiers and the 30% store fee.
• Licensing, how a paid tweak checks it is licensed.
• Revenue and Payouts, when earnings clear and how to withdraw.

Reference

TI_Support is the library tweaks link against. It provides the shared preference store that a tweak and its settings pane both use, and the licensing API that paid tweaks verify themselves with.
