PostBox

PostBox is a Mac-only app that turns the MacBook notch into a drag-and-drop poster. You drag an export into the notch, write one caption, pick destinations, and it posts—shaped for each network—without opening nine browser tabs. On Product Hunt it earned #7 launch-day community interest on 2026-09-05 with 116 points and 12 comments—launch-day interest, not a review.

Honest platform note: PostBox runs as a macOS app (schema lists macOS 15 or later). It will not run on Windows, Linux, or the web. Sessions stay on your Mac; you sign in on each platform’s own page, and tokens PostBox keeps are revocable.

As of the September 2026 homepage, live destinations include YouTube, Bluesky, Dribbble, LinkedIn, X, and TikTok. Threads, Instagram, and Pinterest are marked coming soon. Free covers unlimited posting on every live platform except X (X is Pro-only because X charges for API posts). That makes PostBox closer to a fast local publisher than a full Buffer/Hootsuite team suite.

If you already export frames from Figma or finished clips from Final Cut, PostBox is meant to erase the “nine tabs of re-cropping” hour that comes after creative work. Caption once, let the app pad to a shape that survives every selected destination, and post. Failed destinations keep the draft instead of silently dropping a channel—useful when LinkedIn tokens expire or a design network rate-limits. Version 1.0.29 (banner on the site) called out public YouTube posts and clearer multi-account behavior, which signals an active solo-maintained product rather than a frozen launch page.

Key features

  • Notch drag-and-drop: Drop a finished file into the MacBook notch UI, caption once, post to multiple networks in one action.
  • Per-destination shaping: PostBox pads/crops so the same asset survives each selected platform’s aspect needs—no separate export per network.
  • Multi-account per platform: Free includes 2 accounts per platform; Pro removes the cap so one drop can hit several brand accounts.
  • Immediate post by default: Press Post and it goes live—no required “best time” queue. Scheduling is a Pro feature.
  • Failure-safe drafts: If a platform fails, the draft is kept and you see which destination failed and why.
  • Local-first account handling: Sign-in happens on the platform’s own page; credentials are not meant to live as a shared cloud team inbox like classic social suites.

Pricing

There is no separate /pricing page.

PlanPriceIncludes
PostBox (Free)$0Unlimited posting; every live platform except X; 2 accounts per platform; every Mac you own; no card required
PostBox Pro$14.99/moX posting, unlimited accounts per platform, scheduling

X sits behind Pro because it is the only destination that bills PostBox per API post; other networks stay free to publish on Free.

Pros and cons

Pros

  • Fastest path from finished file → multi-network post if you already work on a Mac
  • Generous free tier (unlimited posts on non-X networks)
  • Local session model appeals if you dislike handing accounts to a cloud scheduler
  • Clear pricing: one Pro price for X + unlimited accounts + scheduling

Cons

  • Mac-only—non-starters for Windows/Linux teams
  • Instagram / Threads / Pinterest still “soon,” so creator stacks centered on IG are incomplete
  • Not a team calendar, inbox, or analytics suite like Buffer or Hootsuite
  • Free users who need X must upgrade

Who should use PostBox?

Use PostBox if you design or create on a Mac, finish assets locally, and want them on YouTube, Bluesky, Dribbble, LinkedIn, TikTok (and X on Pro) without browser tab hell. Skip it if your team needs Windows support, deep Instagram scheduling today, approval workflows, or agency-level reporting—stick with Buffer/Hootsuite (or wait for Instagram to land).

FAQs

Is PostBox only for Mac?+

Yes. It is a macOS download (macOS 15+ per site schema). Send yourself the download link and finish setup on a Mac.

What does the free plan include?+

Unlimited posting to live platforms except X, two accounts per platform, and use on every Mac you own. No credit card required.

Why is X paid?+

X charges for API posts. PostBox keeps other networks free and puts the API cost behind Pro ($14.99/mo) instead of paywalling the whole app.

Is it a scheduler?+

Not by default—posts go out when you hit Post. Pro adds scheduling if you want a queue.
