Postiz vs Buffer: which social media scheduler is right for you?

Last updated October 2026

Choosing a social media scheduling tool comes down to what you actually need. Postiz is an open-source platform built for creators and agencies who want deep automation, AI content generation, and the option to self-host. Buffer is a mature, widely adopted scheduler known for its clean interface and straightforward per-channel pricing. Both tools solve the same core problem, but they approach it from very different angles.

This comparison breaks down their pricing, features, and ideal use cases so you can make the right call without wading through marketing pages.

How the two tools compare at a glance

Postiz: the open-source contender

Postiz has carved out a distinct position in the social media scheduling space by being fully open source. The entire codebase is publicly available, which means you can audit it, extend it, or run it on your own servers without paying a subscription fee. For technical teams, agencies managing multiple clients, and anyone who values data sovereignty, this is a meaningful differentiator.

The platform supports over 30 channels, which goes well beyond the usual social networks. In addition to the standard platforms like Instagram, X, LinkedIn, and TikTok, Postiz lets you schedule and cross-post to Reddit, Discord, Telegram, Slack, Dribbble, and even decentralized networks like Mastodon, Bluesky, and Nostr. It also supports blog destinations like WordPress, Medium, Dev.to, and Hashnode, making it useful for content creators who publish across both social and written media.

Where Postiz really differentiates itself is in its AI tooling. The built-in copilot drafts posts, generates images, and produces short videos. It connects to external models including Claude and ChatGPT and offers an MCP server for agent-based workflows. The platform also includes a Canva-style picture editor, so you can create visual content without leaving the app. AI image and video generation is capped per plan, but the limits are generous on higher tiers.

Automation is another strong suit. Postiz offers auto-posting, auto-liking, and auto-commenting triggered by engagement milestones, along with content recycling for evergreen posts and RSS-to-post pipelines. These features are particularly valuable for agencies and creators who want to maximize engagement without spending hours manually responding to every interaction.

The self-hosting option is worth highlighting. Running Postiz on your own infrastructure eliminates the software subscription entirely. You handle server costs, setup, and updates, and you connect your own API keys for AI features. For teams with engineering support, this can be significantly cheaper at scale than any hosted solution. For everyone else, the managed version at postiz.pro removes that operational burden entirely.

The main tradeoff is maturity. Postiz is newer than Buffer and does not yet match the depth of reporting or enterprise support that longer-established tools offer. That said, the pace of development is fast, and the open-source community contributes features and fixes regularly.

Postiz pricing

Postiz uses flat monthly pricing rather than per-channel billing, which makes costs predictable as you add more social accounts.

The Standard plan costs $29 per month ($23 on annual billing) and includes 5 channels, 400 posts per month, and 3 AI-generated videos. It does not include team members, so it is best suited for solo creators.

The Team plan costs $39 per month ($31 annually) and bumps the channel count to 10 with unlimited posts and unlimited team members. You also get 100 AI-generated images and 10 AI videos per month.

The Pro plan costs $49 per month ($39 annually) and supports 30 channels with 300 AI images and 30 AI videos. This is the sweet spot for agencies managing a handful of clients.

The Ultimate plan costs $99 per month ($79 annually) and includes 100 channels, 500 AI images, and 60 AI videos, making it suitable for large agencies or enterprise teams.

All plans include the advanced picture editor, AI autocomplete, AI copilot, and a 7-day free trial. And again, self-hosting the open-source version is free if you have the technical capacity to run it.

Buffer: the established standard

Buffer has been around since 2010, making it one of the longest-running social media scheduling tools on the market. Its reputation is built on simplicity. The interface is clean and intuitive, the onboarding is fast, and the learning curve is nearly flat. If you want a tool that does the basics well without overwhelming you with options, Buffer delivers.

The platform supports the major social networks: X, Instagram, Threads, LinkedIn, Facebook, Pinterest, TikTok, YouTube, Mastodon, and Bluesky. It does not extend into messaging apps, forums, or blog platforms the way some competitors do, but for most businesses and creators, the coverage is sufficient.

Buffer's free plan is genuinely usable. You get 3 channels, 10 scheduled posts per channel, 100 saved ideas, basic analytics with 30 days of history, and access to the community inbox. The 10-post limit is a queue depth cap rather than a monthly quota, meaning it refills as posts publish. For individuals or very small accounts, this may be all you need.

The AI Assistant handles post drafting and rewriting with options to shorten, expand, or adjust tone. It is functional but more limited than what Postiz offers, with no image or video generation and a knowledge cutoff that may not reflect the latest trends. It works well for refining copy but is not a full content creation suite.

Analytics on the free plan cover follower counts, engagement rates, impressions, and clicks, with weekly summary takeaways. Paid plans unlock advanced analytics with custom date ranges and deeper performance insights. Buffer also offers Analyze as a separate product for teams that need more robust reporting.

The community inbox is a notable inclusion, even on the free plan. It lets you manage comments and messages from connected platforms in one place, which is helpful for maintaining engagement without switching between apps.

Buffer's per-channel pricing model is both a strength and a weakness. It is inexpensive to start with just a few channels, but costs scale linearly as you add more. For agencies or businesses managing many accounts, the math can get unfavorable compared to flat-rate alternatives.

Buffer pricing

Buffer's pricing scales based on the number of channels you connect, which keeps the entry price low but means costs grow with every new account.

The Free plan costs nothing and includes 3 channels, 1 user, 10 scheduled posts per channel, 100 saved ideas, basic analytics, and the community inbox.

The Essentials plan costs $6 per channel per month ($5 on annual billing). It unlocks unlimited scheduled posts, unlimited saved ideas, advanced analytics, the hashtag manager, first-comment scheduling, and API access with 3 keys and 7,500 requests per month. It is limited to 1 user.

The Team plan costs $12 per channel per month ($10 annually) and adds unlimited users, content approval workflows, custom access permissions, and expanded API access with 5 keys and 15,000 requests per month.

Buffer also offers volume discounts for larger channel counts. Channels 11 through 25 drop to $4 per channel, and channels 26 through 50 drop to $3 per channel on the Essentials plan. Even so, managing 10 channels on the Team plan runs $120 per month at the monthly rate, while Postiz supports the same count on its Team plan for $39.

Both platforms offer trial periods. Buffer provides a 14-day free trial on paid plans, while Postiz offers a 7-day trial.

Who should pick Postiz

Postiz is the better choice if you manage a high number of social accounts, need AI-powered content creation beyond text drafting, want to self-host for data control or cost savings, or publish across niche platforms like Reddit, Discord, Mastodon, or blogging sites. Agencies managing multiple clients will find the flat pricing particularly attractive, since adding channels does not increase costs within a given tier. Technical teams that want to customize their tooling or integrate it into existing infrastructure will appreciate the open-source codebase and public API.

Who should pick Buffer

Buffer is the better choice if you want a free plan that is genuinely functional, prefer a simple and polished interface over feature density, only need to manage a handful of channels, or want a community inbox built in. Individuals, small businesses, and anyone who values ease of use over power features will find Buffer hard to beat. The per-channel pricing also works in your favor when you only manage two or three accounts, making it one of the cheapest options at the low end.

Postiz vs Buffer: the bottom line

The decision between Postiz and Buffer comes down to scale and ambition. Buffer is the simpler, more established tool with a generous free tier and an interface that anyone can pick up in minutes. Postiz is the more powerful and flexible option, with deeper AI features, broader platform support, automation capabilities, and the unique advantage of being open source with self-hosting available.

If you are a solo creator or small business managing a few social accounts and want something that just works, Buffer is a solid choice. If you are an agency, a technical team, or a creator who wants more control over your tooling and content pipeline, Postiz offers more for the money, especially at higher channel counts.

Does Buffer have a free plan?

Buffer offers a free plan that includes 3 channels, 10 scheduled posts per channel, 100 saved ideas, basic analytics with 30 days of history, and a community inbox. The 10-post limit is a queue depth, not a monthly cap, so posts refill as scheduled content publishes.

Which tool has better analytics?

Buffer has more mature analytics, with per-post performance metrics, engagement rate tracking, audience growth charts, and weekly summary takeaways available even on the free plan. Advanced analytics with custom date ranges require a paid plan. Postiz offers per-channel and per-post metrics but is still catching up in reporting depth.

Which tool is easier to learn?
