Bootstrap

Default styling is recognisable, so sites can look generic without deliberate customisation
Ships a large stylesheet, and unused CSS must be purged to keep payloads reasonable
Component-based approach fits less naturally into React and Vue codebases than libraries designed for them

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
