Im building a setup now. Any tips on libraries for esp8266 to control the maximum number of leds via i2s DMA?

Well, there's an ESP8266 board called the "PixelBlaze" which is designed for driving these LEDs, but I don't think the firmware is open source:

This page seems to have more information about a couple of different methods - apparently it's also possible to use a UART peripheral:

If you want maximum number of LEDs, I think you want the four-wire LED strips that are driven over SPI, like the APA102 and similar. Much faster than bit-banging on the three-wire strips.
If you want max number of LEDs you have to use HUB based LED panels. They are way cheaper. But harder to control.
Got a link?
For instance: https://nl.aliexpress.com/item/32969045578.html?spm=a2g0o.pr...

You can find how to control them if you search for HUB75. For a couple of dollars you got 2048 LEDS. You can get them in different sizes and LED pitches.
