Postiz review

Postiz schedules posts across more networks than any other tool in this guide, 30-plus, including every network this guide checks for, at a low price per channel: $29/mo for 5 channels. The entire application is open source and can be self-hosted for free, and an AI “smart agent” can draft copy, generate media and schedule a post in one chat flow. It’s also the newest and least-reviewed tool in this guide, and in October 2026 it shut down for all customers after a reported security incident at its hosting provider. ToolsGavel rates it 3.4 out of 5.

What Postiz is for

Postiz markets itself partly as “the publishing layer for AI agents”: alongside a normal calendar and scheduling UI, it ships an MCP server, a CLI and a public API built for AI tools to post through directly. Its own AI smart agent can write platform-tuned copy, generate images or video, and schedule the result in one chat interaction, the most AI-bundled workflow of the five tools in this guide. Network coverage is the widest by far: 30-plus platforms including every one this guide checks for, TikTok, LinkedIn, Threads, Bluesky and X, plus Mastodon, Telegram, Discord, Reddit, Slack, VK and more, most of which none of Buffer, SocialBee, Iconosquare or Later support. The entire codebase (gitroomhq/postiz-app) is open source, so a technically capable team can self-host it for $0 in software cost, though server and Docker setup and separate social-platform developer fees still apply.

What you get on each plan

The October 2026 incident

In October 2026, Postiz shut down for all customers while investigating what founder Nevo David described, in his own posts on X, as a security incident at its hosting provider, Railway. He said Postiz received breach notices that Anthropic and Stripe API keys had been exposed, and the company took the service offline during the investigation before restoring it. None of this comes from an official incident report or postmortem; it’s sourced from the founder’s own social posts and secondary tech-news coverage, so treat the full scope and timeline as unconfirmed beyond what’s been said publicly. A separate, roughly concurrent dispute between David and a terminated contractor, who shared the already-open-source codebase amid a public disagreement, played out around the same time, a signal of a young, founder-led operation still building out its internal process.

What users say in reviews

Postiz’s review base is the thinnest in this guide by a wide margin. G2 rates it 4.8 out of 5, but from only 51 reviews, and Capterra shows a single review at 5.0, not a usable sample either way. No Trustpilot profile was found at all. A handful of reviews describe the hosted pricing as high relative to the project’s open-source framing, expecting the self-hosted free option and finding the hosted Team and Pro tiers priced in line with incumbent competitors instead, though with only 51 total reviews behind that theme, treat it as a single-source observation, not an established pattern. Given the October incident, most existing reviews likely predate it, so expect the current rating to lag behind what a fresh review set might show.

Who should skip it

Skip Postiz if predictable uptime and a longer track record matter more to you than network breadth or price; it’s the newest, least-reviewed tool in this guide, and it had a real security incident and full shutdown as recently as October 2026. Skip it too if self-hosting isn’t realistic for your team; the $0 open-source option needs server and Docker setup most small businesses won’t take on. Buffer and SocialBee both carry far larger review bases if stability matters more than price. See the full comparison in Best Social Media Scheduling Tools for Small Businesses.
