Buffer is a social media workspace that lets creators, brands, and agencies publish, create, and collaborate on content for Facebook, Instagram, TikTok, LinkedIn, Threads, Bluesky, YouTube Shorts, Pinterest, Google Business, Mastodon, X, and Substack. It supports teams and solo users with tools to organize, repurpose, and schedule posts. What sets Buffer apart is its all‑in‑one dashboard that unifies publishing, engagement, and analytics. The platform includes an AI assistant for content ideas, a mobile app for on‑the‑go management, and a free forever plan that removes the need for a credit card.
