Comments
Hey Fazier! I built UpMocker because every time I needed a WhatsApp or iMessage screenshot for a landing page or social post, I had to either screenshot my phone, fake it in Photoshop, or pay for a bloated desktop app that did too much. UpMocker runs in the browser, has platform-native templates for every major messenger + social app, lets you edit bubbles/timestamps/participants inline, and exports clean PNGs in one click. No signup during early access. Would love your feedback on which platforms to add next — TikTok comments and LinkedIn DMs have been the most-requested so far.
