As answered by people managing JavaScript.com and GoSocialMockup.
GoSocialMockup's answer:
Two things. First, it runs entirely in your browser — the text you write and any avatar you upload are never sent to a server, because there is no backend to send them to. Second, it includes a Classic bird-era mode that reproduces the pre-2023 Twitter interface accurately, down to removing the view counts and bookmarks that didn't exist yet. Most generators either skip the old interface or draw it with modern elements still attached.
GoSocialMockup's answer:
Exports are watermark-free and full 2× resolution with no paid tier — you don't hit an upgrade wall after the first download. There's no signup, so there's nothing to create and nothing to cancel. And because rendering is client-side, it works offline once loaded and gives you a genuine privacy guarantee rather than a policy promise. Three generators are included — X/Twitter posts, Instagram posts, and iMessage conversations — instead of just one.
GoSocialMockup's answer:
Social media managers and marketers mocking up post concepts for client approval, designers placing realistic social content into presentations and portfolio work, educators and journalists illustrating examples of how posts spread, and video creators and meme-makers who need a clean screenshot without a watermark across it.
GoSocialMockup's answer:
I needed a tweet mockup for a design comp and found the existing tools all wanted the same trade: a signup, a watermark, or an upgrade prompt before you could download anything usable. Several also uploaded your text to a server to render the image, which is an odd thing to accept for a tool this simple. It turns out none of that is necessary — a mockup is just HTML rendered to a canvas, which the browser can do on its own. So I built the version I wanted: free, no account, no watermark, and nothing leaves your machine.
GoSocialMockup's answer:
Astro for static site generation, Tailwind CSS v4 for styling, and vanilla JavaScript for the editor — no frontend framework runtime ships to the browser. PNG export uses snapDOM to rasterise the live preview client-side. Hosted on Cloudflare Workers static assets. There is no database, no server-side rendering, and no analytics that tracks individuals.
