For Maya animators
The toolkit I use on production shots, and guides written from the same desk.
Maya 2022 to 2026
50+ animation tools across 9 tabs and a 31-button dockable toolbar: tween, pose library with mirror and flip, motion trail, temporary pivot and Mixamo retargeting.
TheKeyMachine is free and open source, but development has ended and it stops at Maya 2025. What it still covers.
Free and paid: animBot, Studio Library, Tween Machine, TheKeyMachine and AnimKit, with what each one does and who it is for.
Why a global mirror flips the wrong axis on some rigs, and the per-control approach that holds up.

About
I’m Mohamed Nasreldeen. For more than ten years I have animated characters and creatures for games and films, including Borderlands 4, Smite 2, Mavka: The Forest Song and Secret Magic Control Agency. I run NasrTech on my own from Cairo. The tools here are the ones I needed while animating in Maya and publishing my own Android apps, and the guides come from the same work. The site earns money from AnimKit licences, Store Kit, purchases in my apps, ads that may appear on articles and tool pages, and a few marked affiliate links.
