Blowhorn vs Postiz
Postiz is the strongest agent-ready scheduler out there, with 30+ networks, a hosted MCP and a self-host option. Blowhorn's difference is who presses Post: your own Chrome, on your own Macs, plus Hacker News, GitHub and LinkedIn outreach.

Strong signal, not bought numbers
Blowhorn doesn't sell followers, likes or repost packages, and it never will. A like from someone paid to click is weak signal: it moves a number and nothing else. Strong signal is a reply, a question, a repost with a real take from someone who knows your work, a thread that turns into a discussion. Blowhorn exists to get your message in front of the people who would answer it, through the profiles of real people who chose to back you.
Postiz and Blowhorn agree more than they disagree: neither sells engagement. Our bet is on people. Blowhorn's sound wave includes the profiles your teammates and supporters add themselves, so the replies under your post come from people who actually chose to stand behind it.
