Boardmix is pretty stable (so far i did not get any bug), its has many great templates. It does what it shall do and it has many many many option. you even get create real kanban board (to replace padlet too!). Short: Its awesome!
The best thing (for me) is that they also allow know to share the board for non-registerd users, so i can use it for my online-workshops without spending extra time for registration and problems with it!

Cons:
- the onboarding took me almost 2 weeks. I did not get an verification code and it took about 5 emails to finally get boardmix that was quite annoying. The 5 Tacos are because the board is far better than I expected it (i have to say i need no single Ai-credit for my purpose, so that is no dealbreaker for me).

All in all: one of the best buys of 2024!
