Buffer alternative
The Buffer alternative with flat, predictable pricing
Buffer charges for every channel you connect, and teams pay more per channel. PostNinja gives you a set number of accounts for one flat price, team seats included on Pro and Agency, so growing doesn't mean a bigger bill every time you add a profile.

Why people choose PostNinja over Buffer
Teams without the per-channel jump
On Buffer, adding a second person moves every channel to the Team rate. PostNinja includes 2 people on Pro and 5 on Agency.
Short-form video in one go
Schedule the same vertical video as an Instagram Reel, a YouTube Short and a TikTok, each with its own caption, from one composer.
AI agents that can publish
Like Buffer, every plan includes an MCP server and API. Your assistant can create, schedule and publish posts, not just fill a queue.

To be fair
When Buffer might suit you better
- Buffer has a free plan (3 channels, 10 scheduled posts each), which is great if you only post occasionally.
- It supports more networks, including LinkedIn, Bluesky, Mastodon and Google Business Profile.
- If you only need one or two channels, Buffer's per-channel price can work out cheaper.
- It includes a comment inbox and unlimited AI writing credits.
If what you need is fast, simple scheduling to the big platforms at a fair price, with your AI assistant able to do it for you, PostNinja is built for exactly that.

FAQ
PostNinja vs Buffer: questions
Is PostNinja cheaper than Buffer?
Usually, once you have more than two channels. 5 accounts cost $15/mo on PostNinja against $30 on Buffer Essentials, and 25 accounts for two people cost $50/mo against $180 on Buffer Team (both billed monthly). For one or two channels, Buffer can be cheaper.
How do I switch from Buffer to PostNinja?
Start your free trial, connect the same social accounts (you log in on each platform, so PostNinja never sees your passwords), and re-create anything you have queued in Buffer. Most people are set up in under an hour, and you can run both side by side until you're happy.
Does PostNinja support everything Buffer does?
PostNinja focuses on X, Instagram, Threads, Facebook Pages, TikTok, YouTube Shorts and Pinterest. LinkedIn isn't available right now and Bluesky isn't supported yet. It doesn't have a social inbox or listening tools: it's built to make planning and publishing fast and affordable.
Can my AI assistant post with PostNinja?
Yes. Connect ChatGPT, Claude, Gemini, Grok or any MCP client to PostNinja and it can draft, schedule and publish posts to your accounts, on every plan. There's also a REST API.
