Does Buffer Have a Free Plan?

Yes, in-fact it has one of the most generous free tiers that we've seen of all the best social media management tools on the market. It allows you to connect up-to 3 channels (e.g. X, LinkedIn, and Instagram) with the ability to schedule 10 posts per channel, allowing for 30 total posts on the free tier (assuming you've connected 3 accounts).

What Platforms Does Buffer Support?

X (Twitter), LinkedIn (Profiles + Pages), YouTube (Shorts), Instagram (Business & Creator Accounts), Facebook (Pages + Groups), Pinterest (Personal & Business), Shopify (Stores), TikTok (Business), Google (Business), Start Pages, and Mastodon. Although there are some API limitations, so you can refer to the Buffer supported channels help docs to better understand any limitations.
