A Buffer alternative that fills its own queue
Buffer is a low-cost social media scheduler with a free plan, a queue and an AI writing assistant. Their site
Buffer is the cheapest sensible way for one person to schedule posts to many networks, and its free plan is genuinely free. Kamu costs more and does the part Buffer leaves to you: it writes the posts from what your product shipped and publishes them. Buffer holds a queue of posts you wrote. Kamu writes them.
Buffer starts at nothing. The free plan connects three channels, holds ten scheduled posts per channel, includes the AI Assistant and never expires. Essentials is $5 a month for one channel as of September 2026, or $60 a year, and Team is $10 a month for one channel with unlimited members and approval workflows. For a solo founder that is about as cheap as software gets, and it is why Buffer is the default answer when someone asks how to post to X, LinkedIn, Instagram, Threads, Bluesky and Mastodon from one place.
The thing it does not do is write. Buffer's AI Assistant will brainstorm and rewrite, and the queue publishes on time. The queue is still empty on Monday morning until you sit down and fill it. That is fine for a creator whose work is the posting. A founder's work is the product, and the queue is what gets skipped in a busy week.
Kamu costs more, from €25 a month on Seed, and it does not ask you to fill anything. It connects to GitHub, reads what shipped from your releases and merged pull requests, and writes a post for each of X, LinkedIn and Instagram, the Instagram one with a picture it makes in your colours. Then it publishes to whichever of those you have connected and hands you a draft for the rest. On a week where nothing shipped it says so and writes nothing.
You lose a great deal in the trade. Kamu publishes to three networks to Buffer's eleven, and drafts Reddit comments for you to post. It has no queue to reorder and no link in bio page, and Buffer's hashtag manager and follower analytics have no equivalent in it. What you gain is that the posting happens whether or not you had time this week, which for one person shipping alone is usually the whole problem.

When Buffer is the better choice
Pick Buffer if you already know what you want to say and only need it to go out on time. The queue, the free plan and the eleven channels are the right shape for a creator, a small shop or anyone whose posting is part of the job rather than a chore squeezed around it. Pick it too if your audience lives on TikTok, Threads, Bluesky, Pinterest or YouTube Shorts, none of which Kamu touches, or if you want a link in bio page and a first comment scheduled under each post. And if price is the whole question, Buffer wins outright. Its free plan does real work for nothing, and €25 a month for Kamu is only a good deal if the posts it writes would otherwise not exist. For a founder who was going to write them anyway, Buffer is the cheaper and the better tool.
Questions
Is Kamu a Buffer alternative?
For a founder who never gets round to filling the queue, yes. Buffer is a scheduler: you write, it publishes on time, and the free plan makes that cost nothing. Kamu writes the posts itself from what your product shipped and publishes them to X, LinkedIn and Instagram, from €25 a month. If you enjoy writing your own posts and only need the timing handled, stay with Buffer.
Can I connect Kamu to Buffer?
No, and it would not gain you much. Kamu publishes directly to the accounts you connect. If you would rather keep Buffer as the place everything goes out from, leave those accounts unconnected in Kamu: it then writes each post and hands it to you as a draft, which you can paste into Buffer's queue at whatever time you like.
Does Kamu have a free plan like Buffer?
No. The cheapest plan is Seed at €25 a month, which runs one product with a cap of 2 X posts a day and one linked LinkedIn or Instagram account, and grants double credits in its first month. Buffer's free plan is a better place to start if you are unsure whether you want to post at all. Kamu makes sense once you know you want the posts and know you will not write them.
Which is better for Instagram?
Buffer, if you make your own pictures and want a queue of them. Kamu posts to Instagram with a picture it generates in your brand colours, which spends credits, and it drives a personal account the way a phone app would, with low daily caps. That suits a founder who would otherwise never post there. It is no replacement for a considered visual feed.
