The free version is sufficient and permanently free, with limits on the number of sources or notebooks, and does not require subscription or credit card.
There is no free plan. The official pricing page only has three paid plans: Starter, Pro, and Pro Plus. Each plan card has a button that says "Start 7-day trial For Free" and is marked "US$0.00 today - cancel anytime", which means a 7-day free trial rather than a permanent free tier. The page and FAQ, including the full feature comparison table, do not have a Free plan column. The website does not disclose how the trial will be handled after it expires. The lowest paid threshold for comparison is the Starter plan at US$29/month (monthly), which includes 10 social media accounts, unlimited scheduled posts and drafts, unlimited team members, 1 workspace, 50GB media library, 1,000 AI credits/month, and 100 daily API posts. Additional workspaces can be purchased for US$19/month. (Checked on 2026-08-09 at postsyncer.com/pricing)
