Hootsuite
BufferAbout Postiz
Postiz is what social media schedulers look like when they're built open: one calendar for X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Mastodon and more, with team collaboration and analytics — minus the per-channel pricing that makes Hootsuite bills absurd.
AI features help generate and repurpose posts, and because you can self-host it, there are no plan limits on channels, posts or team members. Your social credentials stay on your infrastructure.
AGPL-3.0 licensed and growing explosively, Postiz has become the default open-source answer for social scheduling — use their cloud or run your own.
