PostDecks
Preview a post on every platform, then get client sign-off
PostDecks shows exactly how a post will look on Facebook, Instagram, X, LinkedIn, Stories and Carousels, with each platform's real cropping and caption limits. Then get it signed off: send clients a link to approve or comment on, with no login or dashboard for them, or export a PDF proof sheet and PNGs. The previewer runs in your browser, so your images stay private. Pro adds the approval links, email alerts when a client responds, branded exports, and unlimited saved clients.
"Can you show us how it'll look on LinkedIn and Facebook?"
If you run social for clients, you've had that message.
A caption with raw images in an email doesn't show them how the post will actually look, and not everyone wants to log into a scheduler just to approve a post.
So I built PostDecks.
Upload your images and caption once, and see exactly how the post will look across X, LinkedIn, Instagram and Facebook.
Then send the client a link to approve or comment on, with nothing for them to log into. Or export a PDF or PNGs for sign-off.
The preview and export are 100% client-side, so your images aren't uploaded just to preview a post. Nothing leaves your browser unless you choose to create a share link.
Stack: Next.js, React, TypeScript, Tailwind, html2canvas-pro and jsPDF for the export, Supabase and Stripe for Pro, all on Vercel. Built with Claude Code.
Building it out for creators next, Instagram profile grid coming soon.

Who hunted PostDecks?
PostDecks was hunted by Dave Weatherall. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
