Postiz is a product
You log in and work in it: a content calendar, AI that drafts posts and generates images and video, a Canva-like designer, analytics, and agency tools. Great when the job is creating and managing content in one place.
The API-First Postiz Alternative
Postiz is an all-in-one social media dashboard — a content calendar, built-in AI that writes posts and generates images and video, analytics, and agency tools. Postproxy does one thing: the publishing and engagement API — a unified endpoint, 7 typed SDKs, an MCP server, per-platform failure states, and 99.97% uptime. If you want a product to create and manage content in, that's Postiz. If you want the API to build on or point an agent at, that's Postproxy.

OVERVIEW
TL;DR
A quick take in two columns, then the detailed comparison below.
Postiz
Postiz is an all-in-one social media product: a visual calendar across 30+ networks, built-in AI that drafts posts and generates images and short video, a Canva-like designer, analytics, and agency/team management. It's cloud or self-hosted, open-source, and now agent- accessible via an MCP server and a Hermes skill. The API is one surface on a much larger app; the product experience is where the investment goes. Cloud starts at $29/mo, with a 7-day trial.
Postproxy
Postproxy does one thing and does it well: the publishing and engagement API. One unified endpoint for every platform, 7 typed SDKs, an MCP server, and per-platform failure states with retries. Run as a managed service: 99.97% uptime, ~35ms responses (p95 at 150ms), and platform breakage monitored and patched before it lands on you. It's the infrastructure your product or your agent builds on. Scoped API keys isolate every client, and a permanent free tier lets you start without a countdown.

Different tools
Postiz makes content. Postproxy ships it.
They're not the same category. One is a product you create content in; the other is the API that publishes it. That's the choice.
Postproxy is infrastructure
You build on it: one API, 7 typed SDKs, an MCP server, per-platform failure states, and scoped keys. It plugs into agent stacks like OpenClaw and Hermes too. It reliably ships whatever your app, your pipeline, or your agent produces. Narrow scope, done well.
Content can come from anywhere — a person, an agent, even Postiz. Postproxy is the publishing layer underneath, with fewer moving parts to break.
TIERS & LIMITS
Pricing
Self-hosted Postiz is free. Cloud plans compared below.
| Tier | Postiz Cloud | Postproxy |
|---|---|---|
| Entry | $29/mo (5 channels, 400 posts) | $17/mo (Agentic, 5 profiles) |
| Mid | $49/mo (30 channels, unlimited) | $49/mo (Business, 20 groups, unlimited) |
| Top | $99/mo (100 channels) | $399/mo (Enterprise, 300 groups) |
At $49/mo, Postproxy gives you 20 profile groups with unlimited posts, SDKs, failure handling, and scoped keys — same price as Postiz cloud's $49/mo tier, which caps at 30 channels. And the Postproxy price includes the service behind the API: uptime, monitoring, and platform fixes are our job, not yours.
KEY DIFFERENTIATORS
Where Postproxy wins
APIs, SDKs, tenant isolation, and predictable behavior, without running publishing infrastructure yourself.
Unified API
One endpoint, one request shape for all platforms. No platform-specific routing in your code.
Permanent free tier
Postiz cloud = 7-day trial. Postproxy free = permanent, no expiry.
7 SDKs
Typed clients for Node/TS, Python, Go, Ruby, PHP, Java, .NET.
Failure handling
Per-platform state machine with retry states and webhooks.
Scoped API keys
Per-client data isolation for multi-tenant SaaS products.
Managed reliability
99.97% uptime on multi-region infrastructure. Platform API changes, token rotation, and breakage monitored and patched for you — self-hosted Postiz means you own all of that.
Agent-ready
Drive publishing from the agent you already run: an MCP server for Claude, Cursor, and Claude Code, plus skills for OpenClaw and Hermes. Same API, same failure handling underneath.
WHAT THEY DO DIFFERENTLY
Where Postiz is different
AI content studio
Built-in AI drafts captions, generates images and short video, and a Canva-like designer builds visuals — content creation Postproxy leaves to you or your agent.
Content calendar & studio
A drag-and-drop calendar to plan, preview, and collaborate on posts across networks — the all-in-one content-management workflow Postproxy leaves to your own product or tools.
Self-hosting
Open-source with full code access — free if you maintain the infrastructure, handle updates, and manage uptime yourself.
