Postproxy vs Postiz
Postiz is an open-source scheduling tool you can self-host. Postproxy is a publishing API with a unified endpoint, 7 SDKs, and per-client isolation built in.
TL;DR
A quick take in two columns, then the detailed comparison below.
Postiz is an open-source scheduling tool with 19+ platforms, a visual dashboard, and built-in AI content generation. Self-host for free or use cloud plans from $29/mo. The API is secondary — platform-specific endpoints, no published SDKs, no documented failure states or queue system, no MCP server. Cloud has a 7-day trial with no permanent free tier.
Postproxy's API is the product. One unified endpoint for all platforms, 7 typed SDKs, per-platform state machine with retry logic, queue system with timeslots and priority, scoped API keys for multi-tenant isolation. At $49/mo: 50 profile groups vs Postiz's 30 channels. Self-hosting is where Postiz stands apart — but you own infrastructure, platform API changes, token rotation, and uptime.
