Webflow's signature scroll interactions are quietly tanking your mobile performance.

Webflow's signature scroll interactions are quietly tanking your mobile performance.

Those buttery parallax and scroll-triggered animations everyone copies ship a heavy interactions engine and force layout recalculations that wreck your Interaction-to-Next-Paint on mid-range Android phones — which is most of the real world. The portfolio looks incredible on the designer's M-series Mac and stutters on a $200 handset. Animation is a performance budget, not free polish. If your fancy scroll effect costs you a second of load, it cost you conversions too.

Measure on a cheap phone, not your laptop. Fight me in the comments.
