Tool names link to each official site (opens in a new tab). Links marked “aff” are affiliate links. Disclosure
App you replace: Buffer Essentials lists at $5/mo per channel, billed yearly (vendor pricing page, list price as of Oct 2026, checked 2026-10-16). Your saving depends on what the bot costs you; see “Cost after”.
