What our research says

Buffer

Buffer fits solo creators, small businesses and lean agencies who want simple scheduling and analytics with AI help on drafts and no add-on fee. Brands that need social listening, paid-ads management or deep enterprise reporting will outgrow it.

Pros

  • AI Assistant included on every plan, including free
  • Per-channel pricing lets you pay only for the networks you use
  • Covers newer networks such as Bluesky, Threads, Mastodon and Substack
  • Public GraphQL API and CLI with documented rate limits

Cons

  • Costs scale with channel count, so many accounts get expensive on Team
  • Free plan caps the queue at 10 posts per channel and keeps 30 days of insights
  • No social listening or ad management

Postiz

The rare scheduler where the escape hatch is real: same code, AGPL licence, Docker compose, and the maintainer says the hosted build has no extra features. If the price rises or the project stalls you move to your own server. The cost is that you are relying on one maintainer, and the hosted entry plan at $29 is not cheap for five channels.

Pros

  • AGPL-3.0 source on GitHub with Docker self-hosting, ~35k stars
  • Maintainer states hosted and self-hosted builds are functionally identical
  • 30+ networks including Bluesky, Mastodon, Threads, Discord and Warpcast
  • OAuth2, SDK, REST API and MCP for programmatic posting
  • n8n, Make.com and Zapier integrations

Cons

  • Hosted Standard is $29/month for only 5 channels and 400 posts
  • Effectively a one-maintainer project, so roadmap and support depend on one person
  • No company entity or country published
  • AGPL is a real constraint if you want to embed it in a closed product

Which one fits

Choose Buffer if you need

  • Solo creators and small businesses posting to a handful of networks

Choose Postiz if you need

  • Agencies and creators who want an exit from Buffer-style lock-in
