Hi Aseprite friends! ^_^/
I’m going to make an Aseprite Script compilation here, I’ll try to gather links and info about all the scripts the community has made into this post. If you are interested in scripts and can be of any help, please don’t hesitate and help me!! 
HOW TO INSTALL A SCRIPT:
- Download the script (scripts are files with .lua extension, so if you download them as a .zip file you will need to uncompress them)
- Open the user script folder
- Copy the script in that folder (if you want you can also create folders there for organisation)
- Restart Aseprite.
- Then you will be able to access to that script from the File > Scripts > YourScriptName menu option
- You can also create a Keyboard Shortcut for each script that you want from the Edit > Keyboard Shortcuts menu (type “script” in the search box to find them easily)
HOW TO CREATE A SCRIPT:
- You should know how to program a little bit, or at least don’t be scared of trying
- Learn a bit about Lua:
2.1 all you need to know about Lua.
2.2 online tester for normal Lua code. - Aseprite scripting API:
3.1 on GitHub
3.2 on Aseprite.org - Get help from a (free) LLM (they can teach you and also help you fix bugs):
4.1 Anthropic’s Claude
4.2 Google’s Gemini
4.3 OpenAi’s ChatGPT
4.4 Local (Open Source) models using Ollama

I’m making some scripts too (I’m not very good though), when they are more or less functional I’ll be adding them into the list.
Also, I’m sure that there are lots of people making Aseprite scripts out there, so if you know (or you are) one of them, or have any suggestion, please leave a comment!! ^^
