Composer
Ready to publishShipping the Fediverse scheduler tonight. Same post goes to Mastodon, Bluesky, and X — captions tweaked per network.
Platforms
Major networks and the open social web in one composer. Listening is separate — we do not pretend Reddit or Hacker News are publish targets.
Features
Scheduling, listening, and an agent API on top of a composer — not a wall of invented social proof.
Write once and fan out to the big platforms and the open social web. Accounts you actually connected — not a fake checklist.
Keep a shared draft, then tweak copy where X, LinkedIn, or Mastodon need a different voice or length.
Send it immediately, or pick a time. The calendar and queue use the same composer path.
Reddit and Hacker News are listen-only. We surface what is being said; we do not fake a publish button.
List accounts, publish, and schedule over HTTP. Same path the dashboard uses — useful if a coding agent is doing the posting.
Campaigns, overlays, and AI sit behind More options so the first post stays a short path.
How it works
01
Sign in with Google, pick a project, connect the networks you actually use. Official OAuth — we never ask for your social passwords.
02
One caption, optional media. Tweak copy per platform if you want. Character limits show up after you pick accounts — not before.
03
Send it now, or pick a time. Campaigns, overlays, and AI stay behind More options so the first post stays a short path.
A note from Matt
I was tired of paying for schedulers that treat Mastodon, Nostr, and Telegram as afterthoughts — or skip them entirely — while charging agency prices for a compose box.
PostBroadcaster is the tool I wanted: one composer for the big networks and the open social web, plus listening when I need to see what is being said. It is early. I use it myself. If something breaks, email me and you get a person, not a ticket queue.
There is no fake customer count on this page. When there are customers, I will put their names here.
