A Postiz alternative focused on approving agent drafts

Why someone might look for a Postiz alternative

Postiz is a capable open-source scheduler. People comparing alternatives usually want something specific:

• Governance for agents. Postiz gives agents an MCP server, CLI and API. If several agents post for you, you may want each one limited to certain networks and actions, with approval required until it proves reliable.
• Proof of review. Regulated or careful teams want a verifiable record of who approved each post and why it was drafted.
• A smaller surface. Some self-hosters prefer a tool that does fewer things so there is less to run and audit.

When Postiz is the better fit

Choose Postiz if you need YouTube, Reddit, Discord or the 20+ other networks it lists. SocialHandoff covers eight: X, LinkedIn, Bluesky, Mastodon, Threads, Instagram (professional accounts), Facebook Pages and TikTok. Postiz also includes AI image and video generation and RSS auto-posting, which SocialHandoff does not.

How SocialHandoff differs

• One key per agent, scoped by network and by permission (draft, schedule, analytics).
• Trust ladder: new agents are draft-only; promotion to auto-publish is per network and can be automated with autoPromote in .socialhandoff/policy.json.
• Guardrails for banned topics, per-network length, missing alt text, daily limits and blocked link shorteners.
• Kill switch that holds every queued post until you resume.
• Hash-chained audit log you can verify with GET /v1/audit/verify.

Moving from Postiz

SocialHandoff can import from Postiz and offers a Postiz-compatible API slice, so existing scripts need fewer changes. See importing from Postiz.

Questions to ask before switching

Start with the networks you actually post to. If your list includes YouTube, Reddit or Discord, Postiz covers ground SocialHandoff does not. Next, list the agents or scripts that call your scheduler and what each should be allowed to do. If you want a changelog bot limited to Mastodon drafts and a marketing agent limited to LinkedIn, SocialHandoff's per-agent scopes fit that directly. Finally, consider whether you need to prove, later, who approved each post and from what source it was drafted.
