Posting to five social networks should not mean opening five apps, reformatting one post five times, and losing track of what went live where. Postiz exists to end that routine. It is an open source social media management platform for scheduling, automating, and analyzing content, built around one visual calendar, 30+ supported networks, and a rule its makers repeat proudly: agents propose, people approve.
Key Takeaways
Postiz schedules, automates, and analyzes social content from one calendar across 30+ networks, including X, LinkedIn, Instagram, TikTok, YouTube, Threads, Bluesky, and Reddit.
It is open source under the AGPL-3.0 license, with 40,035 GitHub stars and 7,584 forks as of October 29, 2026, and the self-hosted edition is free apart from your own server costs.
The cloud edition starts at $29 a month with a 7-day free trial, and the same core product ships in both editions, with no features gated behind the cloud.
AI agents such as Claude, ChatGPT, Cursor, Codex, and Gemini can draft posts through the Postiz MCP server and CLI, but every agent-created post lands in the calendar for human review before anything goes live.
The honest catch is setup: self-hosting means running your own database, queue, and storage, and getting your own developer apps approved by each network can take weeks.

The problem: one post, many networks, no single view
Every network wants its own format, its own image size, and its own best posting time. A creator or a small team ends up copying text between tabs, re-uploading media, and guessing what already went out. Postiz replaces that scattered workflow with a single calendar where a post is written once, previewed per channel, and scheduled with each channel's settings kept intact.
The project lives at gitroomhq/postiz-app on GitHub, and its own README defines it plainly: "Postiz is a social media management platform for scheduling, automating, and analyzing your content." That three-part definition maps to the product: a calendar for scheduling, an API and automation integrations for automating, and built-in analytics for measuring what worked.
What you can do with it
Postiz covers the full loop from idea to published post to performance report, and its feature set reads like a checklist of what paid schedulers charge for.
First, scheduling. You write a post once, adjust it per channel, and send it to several networks from the same composer. The calendar shows everything at a glance, and recurring features such as repeated posts, posting sets, RSS auto-post, and evergreen content recycling keep older content working without manual reposting.
Second, analytics. The cloud plans define analytics as impressions, likes, comments, shares, bookmarks, and engagement rates, so you can compare channels without exporting data to a spreadsheet.
Third, teamwork. Team members can be invited to comment on and schedule posts, and the platform supports customer folders and groups, which matters for agencies managing several brands from one account.
Fourth, automation. Postiz offers a public REST API and webhooks, plus integrations with n8n, Make, and Zapier, so scheduled posting can be wired into larger workflows, for example auto-posting a new blog article or a product update.
The agentic twist: agents draft, humans approve
Postiz calls itself "the agentic social media scheduling tool," and this is where it differs from older schedulers. Through the Postiz MCP server, CLI, and installable skill, AI agents such as Claude, ChatGPT, Cursor, Codex, Gemini, and OpenClaw can connect to your calendar and draft posts. The official About page documents 17 AI agents, and every plan, including the cheapest cloud plan, includes the MCP server, CLI, API, and webhooks.
The safeguard is the part worth quoting, because it answers the obvious worry about handing a brand account to an agent. According to Postiz, "Agents propose, people approve. Every post an agent creates lands in your calendar first, so you can review, edit or reschedule before anything goes live." In other words, the agent does the drafting labor and the human keeps the publish button. AI generation also covers copy, images, and short video clips, with monthly quotas that rise with each cloud plan.
Self-hosted vs cloud: same product, different tradeoffs
Postiz is unusually clear about the deal between its two editions. Its README states that the cloud and self-hosted editions provide "the same core Postiz product and features" and that "We do not gate features or limit the license." Self-hosting is free forever under AGPL-3.0, and you pay only for your own infrastructure. The cloud edition, by contrast, trades money for convenience: no servers to run, no developer apps to get approved.
Aspect | Detail |
|---|---|
Self-hosted | Free under AGPL-3.0, unlimited channels, unlimited posts per month, unlimited team members, you run the server |
Cloud Standard | $29 a month ($23 billed annually), 5 channels, unlimited posts, 7-day free trial |
Cloud Team | $39 a month ($31 billed annually), 10 channels, unlimited team members |
Cloud Pro | $49 a month ($39 billed annually), 30 channels, 300 AI images a month |
Cloud Ultimate | $99 a month ($79 billed annually), 100 channels, 500 AI images a month |
The self-hosted stack is a real stack, not a single binary: PostgreSQL through Prisma, Redis for queues and rate limiting, and since version 2.12.0, Temporal for scheduled posts and background workflows. The docs also warn that setting Stripe keys switches the whole app into billed mode, enforcing plan caps, which almost no self-hosted install needs.
The bigger self-hosting cost is time, not money. Each network requires your own developer app, and Postiz's own FAQ notes that approvals can take weeks, and for Facebook, Instagram, Threads, and YouTube usually more than a month. The founder puts the same point in plain terms: you can run everything free on a roughly $5 a month server if you spend a few weeks getting OAuth providers approved, otherwise the cheapest cloud plan is $29 a month.
A solo founder, no funding, and fast growth
Postiz was started in September 2024 by Nevo David, a full-stack engineer who had previously built Gitroom, a tool for open source launches, and worked in growth at the open source startup Novu. His stated principles are blunt: a non-funded company, everything open sourced, and "Charge only for cloud costs, never force developers to pay."
The revenue story shows that model working. In November 2025 he reported Postiz earning about $14,000 a month. In a later Indie Hackers account he reports growth to $113,000 in monthly recurring revenue, driven first by automation integrations such as the official n8n node, then by agentic usage through tools like OpenClaw. Growth, by his account, was organic, with no ads. The project also won Product Hunt attention across four launches, from its original launch in November 2024 to an agentic scheduler launch in May 2026.
That trajectory also explains the star count. An independent snapshot on October 17, 2026 counted 37,327 stars, and by October 29, 2026 the repository had grown to 40,035 stars with 7,584 forks, a gain of more than 2,700 stars in under two weeks.
Who should use Postiz, and who should skip it
Postiz fits creators, indie hackers, agencies, and developer-led teams who want one calendar for many networks and like the idea of owning their tool. It fits especially well if you already self-host other tools, or if you want AI agents to draft content while you keep approval control.
It is less suited to someone who wants to connect an account and post within ten minutes. If you self-host, budget an afternoon for the stack and weeks for network approvals. If that sounds like too much friction, the cloud trial exists precisely to skip it.

Can AI agents post directly to my accounts?
No, not without your approval. Agents draft through the MCP server or CLI, and every agent-created post lands in your calendar first, where you can review, edit, or reschedule it before anything goes live.
What is the catch with self-hosting?
Setup effort. You run PostgreSQL, Redis, and a Temporal stack, and you must register your own developer app with each network. Approvals can take weeks, and for Facebook, Instagram, Threads, and YouTube usually more than a month.
How is Postiz different from Buffer or Hootsuite?
The core scheduling is similar, but Postiz is open source, so the full codebase is public and self-hostable, the same core features ship in both editions, and its agent features, MCP server, CLI, API, and webhooks, are included in every plan rather than gated behind higher tiers.
Who makes Postiz?
Postiz was started in September 2024 by founder Nevo David, who runs it as a non-funded company under Gitroom, with the stated principle of charging only for cloud costs and never forcing developers to pay.
