Platforms
Schedule posts to 9 platforms
Socialync connects to 9 platforms: Instagram, TikTok, YouTube, Facebook, X, LinkedIn, Threads, Bluesky, and Pinterest. Each page below covers one of them. You will find what a post can contain, the longest caption Socialync publishes, how long a video can run and which Socialync features apply to that platform.
The numbers come from the limits the composer checks before a post goes out, so you can test a caption or a clip against them before you upload. Where a platform publishes its own video specs, the page links to the video spec tool with the date those numbers were last read.
The free plan covers Instagram, TikTok, YouTube, Facebook, LinkedIn, Threads, Bluesky, and Pinterest with 5 posts a month and no card. X posting is on paid plans. Paid plans start at $20 a month and include 5 connected accounts. Free accounts can schedule 2 months ahead and paid plans 12.
