PostBox turns the MacBook notch into a drag and drop poster for the work you make. Drag an export in, write the caption once, and post to X, Bluesky, Threads, LinkedIn, Dribbble, Instagram, Threads, Pinterest Behance and Cosmos at once.
Hey Product Hunt 👋 I'm Jason, the founder of Postbox.
Today I'm bringing Postbox to Product Hunt for the first time.
I love designing in Figma and fixating over every pixel perfect detail. What I don't love is formatting and staging my designs to be engaging for social platforms. Although I do want as much visibility as possible.
Hence I created Postbox, a design staging and posting tool. Simply drag and drop a frame (or multiple), pick a preset or mockup. Then post to all platforms with one click, including: X, LinkedIn, Threads, BlueSky, Cosmos, Behance, Dribbble, Instagram and Pinterest.
The first product hunt users will have a launch gift
Does it allow users to customize the workflow for different types of content like portfolios or announcements?
Using the MacBook notch as a quick drag-and-drop space is such a clever idea. Posting to several platforms frem one place makes the workflow much simpler.

Who hunted PostBox?
PostBox was hunted by Jason Coawette. 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.
