What Postiz does well
Postiz is a feature-rich open-source scheduler. It supports more channels than Catpix, includes AI copilots, and exposes an API and MCP server. Self-hosting gives teams control over data and costs, while the hosted plans start at $29/month.
Postiz pricing
Postiz has a 7-day trial. Standard is $29/month for five channels, Team is $39 for 10, Pro is $49 for 30, and Ultimate is $99 for 100. Every plan includes the API and MCP server. Self-hosting is available.
What Catpix costs
Catpix is free. There is no per-channel fee, no per-seat fee, and the API is included with an account. X is the only metered network: Catpix passes X API costs through at cost ($0.015 for a plain post, $0.20 for a post with a link). Catpix currently supports eight platforms: Bluesky, X, LinkedIn, Facebook, Instagram, Threads, TikTok, and YouTube.
Where Catpix wins
- No per-channel or per-seat math: adding a platform does not add a new line item.
- The API is included with an account instead of being an enterprise upgrade.
- Open source: you can inspect the code, contribute, or self-host later.
- Android app, while many competitors are web-only or slower on mobile.
- X API costs passed through at cost instead of bundled into a subscription.
Where Postiz still wins
- More channels and AI features.
- Self-hosting and data control.
- MCP and agent tooling.
- Larger team and channel limits.
- A broader open-source ecosystem.
