What is Postiz?
Postiz is an open-source "agentic social media scheduler": cloud plans from $29 a month (Standard, 5 channels) to $99 (Ultimate, 100 channels), or self-hosted on your own server at no licence cost. Every plan includes the hosted MCP server, the Postiz CLI, the public API and webhooks, so Claude, ChatGPT, Codex, Cursor or Gemini can schedule through it. It publishes to X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Threads, Pinterest, Reddit, Discord, Bluesky, Mastodon and more. Like Blotato, it is the last mile only: it does not find the content.
- Open source and self-hostable
- MCP server, CLI, API and webhooks on every plan
- Wide network list including Reddit, Discord, Bluesky and Mastodon
- No trend or viral discovery
- No drafts, review or approval gate for what an agent sends
- Channel caps per plan (5 on Standard)
Pricing: from $29/mo for 5 channels (7-day trial); self-hosting free
What is Zernio?
Zernio prices by connected account instead of by plan: the first 2 accounts are free with no card, accounts 3 to 10 cost $6 a month each, 11 to 100 cost $3, and beyond that $1. Every account gets unlimited posts, threads, first comments, a queue and calendar, analytics, an inbox for comments, DMs and reviews, ads management and full API access, with the first 10,000 messages and 500 managed ads a month free. It reaches Instagram, TikTok, Facebook, YouTube, X, LinkedIn, Pinterest, Bluesky, Reddit, Threads, WhatsApp, iMessage, Telegram, Slack, WordPress, Shopify and Google Business. It is infrastructure for your accounts; it does not discover what is going viral on others.
- Two accounts free, then $6 each: cheap for a small footprint
- Inbox, ads and messaging (WhatsApp, Telegram, Slack) in the same API
- Unlimited posts and full API on every account
- No viral discovery or trending radar
- An API first; the UI is thin for a content team
- Costs scale with accounts, not with people
Pricing: 2 accounts free; $6/account/mo from the third
When to buy one of these two
You came here comparing two tools, not looking for a third. So first, plainly, what each one is the better buy for:
- Postiz if your job is teams that want an open-source scheduler their agent can drive, or to self-host and own the data. Open source and self-hostable.
- Zernio if your job is developers and agencies that want per-account pricing and messaging channels next to social publishing. Two accounts free, then $6 each: cheap for a small footprint.
If either of those sentences describes your job, you have your answer and the rest of this page is not for you. What follows is for the case where neither one does.
The third option: ViralHunt
ViralHunt is a viral-content discovery platform that tracks the top-performing posts across 12 networks, TikTok, Instagram, Facebook, Pinterest, Reddit, X, Bluesky, Mastodon, Douyin, RSS, Quora and Tumblr, in real time. Beyond discovery, it turns trends into a team workflow with an editorial Kanban board, an AI content studio and built-in team chat, and now schedules and auto-publishes finished posts to 11 social networks, with separate brand/client projects. So a whole team can find, create and publish content in one place instead of stacking a discovery tool, a workflow tool and a scheduler.
- Tracks viral posts across 12 networks in one dashboard
- Editorial board, AI studio and team chat built in, no extra tools
- Schedules & auto-publishes to 11 networks, with multi-brand projects
- Affordable, a free plan that never expires, plus a REST API for AI agents
- Not a dedicated enterprise listening/analytics suite
- Younger brand than the incumbents
Pricing: from $29/mo
Comparing Postiz and Zernio because neither one quite does what you need? ViralHunt has a free plan that does not expire, so checking is free and there is no countdown.
