Comparison
Cadenus vs Postiz
The Cadenus team · Updated September 2026 · Based on hands-on analysis of public sources
Postiz is open source, publishes to 30+ platforms and is cheap per channel. Cadenus covers fewer platforms and adds the client-facing layer an agency needs: approvals, a white-label portal, video review and per-client margin. Here is the honest breakdown.
These two are closer than the rest of this list. Both connect AI agents over MCP, both expose a REST API, both publish natively, and neither is an enterprise suite. The difference is who they are built for. Postiz is a developer-first scheduler you can self-host, priced per channel, with the widest platform list in the category. Cadenus is built for agencies that answer to clients, so approvals, a white-label portal, video review and per-client profitability come first, and the platform list is deliberately shorter. Below is where each genuinely wins, including where Postiz is the stronger pick.

The limits
Where Postiz strains for video agencies.
Postiz organizes client channels, but not client approvals
Postiz includes customer groups for organizing channels across multiple clients or brands, on every paid plan. What its current public product pages do not document is an external, white-label portal where a client approves without an account, or a mandatory gate that blocks publishing until they do. A public approve and reject link was requested and closed as not planned in June 2026, and role-based control over an approval workflow is still an open request. An agency that needs sign-off before anything goes live runs that part over WhatsApp and email next to it.
See client approvalsAn agent with no brake
Both products let an AI agent publish to a client account. The difference is what happens when the client has not said yes yet. In Cadenus, a brand that requires approval refuses a direct publish and saves the post as a draft instead, so automation cannot get ahead of the client. No equivalent client-facing gate is documented in Postiz’s current public product materials. That guardrail is a large part of why you would hand an agent access to a client account at all.
See how agents publishIt shows reach, not money
A scheduler reports on posts. It cannot tell you that one client costs forty hours a month against an 800 EUR retainer. Cadenus ties logged time and costs to each client so you see the real margin per client, which is the number that decides who you keep.
See per-client P&LNone of this makes Postiz a worse tool — it simply stops where a video agency's work keeps going, which is the gap Cadenus was built to close.

The honest take
Where each one wins.
Where Cadenus wins
- ✓ Client approvals and a white-label portal, where the client signs off from a magic link with no account to create.
- ✓ An approval rule an AI agent cannot bypass, so automation stays inside what the client agreed to.
- ✓ Versioned video review, built for the Reels and TikToks that make up modern client work.
- ✓ Per-client profitability: cost against retainer, and the real margin on each client.
- ✓ Notion as the content source, with the result written back. Postiz has no Notion integration.
Where Postiz is stronger
- → Far wider platform coverage: 30+ networks including Discord, Reddit, Mastodon and Telegram, against six in Cadenus.
- → Open source. You can host it on your own infrastructure and pay nothing for the software.
- → Cheaper per channel at scale: 100 channels for USD 99 a month on Ultimate.
- → Unlimited team members from USD 39 a month.
- → A public, mature API and webhooks, with an active open-source community around them.
- → An official agent CLI alongside the MCP server, documented for Claude, ChatGPT, Cursor and Codex.
- → Customer groups on every paid plan, for keeping several clients’ channels apart.
Verdict
Which should you choose?
Choose Postiz
Pick Postiz if you publish to many networks, want to self-host or keep software costs near zero, and nobody outside your team has to approve anything before it goes live.
Choose Cadenus
Pick Cadenus if clients approve your work: you need sign-off without accounts, a white-label portal, video review and margin per client, and you would rather an AI agent be stopped by an approval rule than trusted not to publish.
Questions
Cadenus vs Postiz, answered.
Is Cadenus cheaper than Postiz?
At the entry level yes, EUR 19 against USD 29, and the Cadenus plan includes eight channels against five. At scale Postiz is cheaper per channel: 100 channels for USD 99 a month. The comparison only favours Cadenus once you count what you would otherwise buy separately for approvals, client reporting and finance.
Can I self-host Cadenus like Postiz?
No. Postiz is open source and can run on your own servers. Cadenus is hosted only, with media stored in the European Union. If self-hosting is a requirement, Postiz is the right answer.
Do both work with AI agents?
Yes, and both go further than an API: each ships an MCP server and an agent CLI, and both work with Claude, ChatGPT, Cursor and Codex. The difference is what happens when an agent tries to publish to a client account. In Cadenus an approval rule can refuse it and save a draft instead. No equivalent client-facing gate is documented for Postiz.
Which one publishes to more platforms?
Postiz, by a wide margin: 30+ networks against six. If you need Discord, Reddit, Mastodon or Telegram, Cadenus does not cover them.
