We just released version 2.0 of Tinkerwell bringing Windows and Linux support as well as generic framework support.
Tinkerwell 2.0 is rewritten from scratch in Electron and therefore brings Linux and Windows support!
Tinkerwell 2.0 is fully framework agnostic. You can now Tinker with any PHP application you want. Out of the box, Tinkerwell supports Laravel and Wordpress, but you can easily create your own custom driver to support other framework. Check out the Documentation on GitHub to get started.
In addition to being able to bootstrap custom PHP applications and frameworks you can now also create a custom driver for your own applications, that provide custom context menu items that will be available in the Tinkerwell UI.
