About MicroPoster.so

MicroPoster inverts the usual crossposting workflow. Instead of asking you to compose inside its dashboard, it watches the account you already post from and mirrors what appears there to X, Threads, Bluesky and Mastodon — meaning you keep using whichever native app you like and never open the tool after setup, which the vendor claims takes about 40 seconds. The adaptation layer is where the work happens. Long posts are auto-split into native threaded conversations respecting each network's character limit rather than truncated; text threads can be converted into native image carousels for the platforms that reward visuals; images are resized and cropped to each platform's exact dimensions; links are processed so preview cards render correctly everywhere; and video format, duration and file size are checked against each destination before publishing. Alongside mirroring, it runs autoplug and auto-repost automations, scheduling, drafts and an AI co-writer. Sync frequency is a tiered feature — 30 minutes on the entry plan, 15 on the higher ones — as are the monthly crosspost and repost allowances and the number of connected accounts and concurrent automations. The vendor states it is built by a solo indie founder and fully bootstrapped, and cites 454+ creators and 8,800+ posts published or scheduled.
