Alpaca.markets is great! What are other alternative for personal solution?

Have you looked at Interactive Brokers? They seem to support more complex order types than Alpaca, which can meaningfully impact returns of a automated trading strategy.

IB is good if you don’t need them. I’ve asked questions via their website and called them to no avail. That being said they seem solid.
