from != for. You can't just use someone else's trademark in your product name, especially when related to it.

Re:youtube - you link to several videos in the section "Why TanStack Start". Looking closer, they are actually about a project "Tanstack Start" (which is actually by TanStack folks) and not about this project "Tanstack Starter Kit". You linking to them confused me (as it seems it was intended to). Linking to videos as testimonials, knowing they aren't about your product, but the similarly named pre-existing product is very sketchy.

- Your logo is near copy of theirs

- Your name is near copy of theirs (just adding "er Kit")

- You link to videos about them from your homepage in a "Why" section
