Why is the ZIP file so incredibly small? Do I have to install Java or .NET?

StarTools is a completely native, self-contained application that does not require any further installation of helper libraries or run-time frameworks.

Everything in StarTools was written from the ground-up and has been hand-optimised, from the image processing algorithms to the UI library, from the file importing to the font renderers, for the multi-platform framework to the decompression routines. Why? Because we feel it is important to be master of our own destiny (and make you master of your own destiny by extension) and fundamentally understand each and every ingredient that goes into the mix.

Fundamentally understanding the different algorithms, optimisation techniques and data structures gives us the ability to push the boundaries and create truly novel techniques and algorithm implementations.

Please note that Linux users, will still need X11, GLIB 2.15, zenity and wmctrl installed on their system.



Download

One ZIP archive contains Windows, macOS and Linux versions of StarTools. Do not download StarTools from anywhere else but startools.org. We do not allow distribution of StarTools by any other party, on-line or off-line.


macOS notes

On later versions of macOS, users may have to "unquarantine" StarTools, before the OS allows it to run. Alternatively StarTools can be launched via control + clicking (right clicking) on the application, Show Package Contents, navigating to Contents/MacOS and clicking on the application.

The following command unquarantines StarTools;

xattr -dr com.apple.quarantine StarTools.app
