MultiPost-Extension

MultiPost skips the API problem entirely. It is a browser extension that pushes one piece of content to more than ten platforms by driving the sessions you are already signed into, so there is no login, no registration, and no API key to apply for.

That architecture is the whole story. Getting official publishing access to Instagram or TikTok means an app review process that runs for weeks and frequently ends in rejection for small developers. An extension that fills in the same forms you would fill in yourself sidesteps every bit of it. Install it and start posting.

Platform coverage leans Chinese: Xiaohongshu, Weibo, Zhihu, and Bilibili sit alongside TikTok and YouTube. For a Western only audience, a proper scheduler like gitroomhq/postiz-app or brightbeanxyz/brightbean-studio fits better. This is Apache licensed, free, and has nothing to sell you.

The catch is that browser automation breaks whenever a platform changes its markup, and nothing publishes while your browser is closed. This is a distribution tool, not a scheduler. Anything that has to go out at 9am on Tuesday while you are asleep needs a server, and this is not one.
