Postiz vs Buffer: Features, Pricing and Reviews in 2026

Postiz is a social media scheduling platform that combines AI content creation, visual planning, and multi-platform publishing in one place. You can write a post once and send it to multiple platforms at the same time, with each channel getting its own preview so you can adjust the text or media per platform.

The built-in AI assistant helps you write captions, generate images, and even create short videos. It also supports team collaboration, approval workflows, and detailed analytics pulled from each platform.

Postiz is open source under the AGPL-3.0 license, so developers and privacy-focused users can self-host it for complete data ownership at no ongoing cost.

Buffer is a social media scheduling and management tool that connects to over 11 major platforms from one simple dashboard. You can write, schedule, and publish posts without logging into each account separately. It includes tools for planning and storing content ideas, managing replies and comments through a unified inbox, and tracking post performance with clear and simple reports.

Buffer also includes a built-in AI assistant that helps you write captions, repurpose content for different platforms, and think of new ideas. A Start Page feature lets you build a simple link-in-bio landing page, so you can share one link across all your social profiles.

Buffer offers a free plan and two affordable paid tiers suitable for individuals, teams, and agencies.
