UpMocker

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.

This is super useful! As someone who creates landing pages frequently, having a browser-based mockup tool that looks authentic is a huge time saver. The fact that it supports so many platforms (WhatsApp, iMessage, Discord, etc.) in one place is impressive. No signup needed is the cherry on top. Great work!

I’ve always struggled with creating realistic chat and social media screenshots for my projects—Photoshop takes too long and phone screenshots look messy. UpMocker is a total lifesaver. The platform-native templates for WhatsApp and Instagram are spot-on, and the ability to edit everything in-browser without signing up is a breath of fresh air. Highly recommended for any founder or marketer!

This is a great tool! I especially like the clean interface and how fast it works. Will definitely use this for my projects.

UpMocker is an absolute lifesaver for creators and marketers. The social and chat mockups look 100% authentic, and being able to edit every detail without signing up is a huge plus. Highly recommended!

This is a practical niche: authentic-looking chat and social screenshots are often needed for landing pages, docs, and ads, but making them manually is slow. Covering email plus social plus messaging in one browser tool is compelling; reusable presets for brand styles would be a useful next step.

UpMocker is a clean, useful tool with clear appeal especially its no-signup, in-browser approach and realistic platform templates but it’s entering a crowded space alongside tools like Canva and Figma. Its strength is speed and simplicity for creating authentic-looking chat and social mockups, but long-term success will depend on how customizable and accurate those templates are, and whether it offers enough depth to go beyond quick, lightweight use cases.

Useful utility. A strong growth move here would be template-led SEO plus fast share loops: let users generate a mockup in one click, then export with a subtle branded footer and a remix link. That turns every shared mockup into acquisition while keeping the product genuinely helpful.

was actively looking for something like this for marketing. Will be great if you could also add media support
