As a tech indie hacker, what tools do you use for building AI/LLM products?

I am a tech indie hacker who built products like alin.io and treescale.com; I'm curious about your toolset for building modern AI, LLM-based products nowadays.

It would be great to see something like

• No code tools you used to build AI Product
• Maybe Python framework?
• Where do you host this kind of stuff?

Thank you 🫡
