MUI

Escaping the Material Design look takes more theming effort than teams expect
Bundle size is significant, and careless imports pull in far more than needed
Advanced components such as the full data grid require a paid licence
Major version upgrades have historically required real migration work

PostHog

The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
Accounts without a card on file are limited to 1 project; adding one raises it to 6
Data retention is 1 year until a card is added, which extends it to 7 years
Support is community-only until the account is on a paid plan
Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
