Postiz is an AGPL-3.0 social media scheduler with 29.8k GitHub stars that posts to 20+ networks, ships AI text/image/video tools and an MCP server, and starts at $29/month or free if you self-host.
Postiz is an open-source, AI-powered social media scheduler that posts to over 20 networks (including Bluesky, Threads, Mastodon, Reddit and Warpcast), ships its own MCP server and a real public API, and is fully AGPL-3.0 self-hostable. We rate it 87/100 — the most credible 2026 open-source alternative to Buffer and Hootsuite for tech-savvy creators, agencies and developer marketing teams who want AI workflows without paying enterprise SaaS prices.
Postiz launched as an open-source project in , built by indie hacker Nevo David — the same engineer who previously bootstrapped open-source notification platform Novu past 20,000 GitHub stars. The project sits at github.com/gitroomhq/postiz-app with 29,839 stars, 5,403 forks and 223 open issues, and the team shipped v2.21.7 on . Unlike Buffer or Hootsuite — which lock advanced features behind $99–$199/month plans — Postiz publishes every line of source under AGPL-3.0, runs on a Next.js + NestJS + Prisma + Temporal stack, and lets you self-host the entire platform on a single Docker host.
The specific problem Postiz solves is the "creator tax": legacy schedulers charge per channel and per seat, then gate developer-friendly features (public API, webhooks, RSS auto-posting, MCP) behind their highest tiers. Postiz inverts that — the public API and webhook automations show up on the entry-level Standard plan, and you can plug Postiz into n8n, Make.com or Zapier with the official n8n-nodes-postiz and @postiz/node SDKs.
On Product Hunt, Postiz launched to a wave of positive reviews from indie hackers and SaaS founders, and the Product Hunt review thread consistently flags fast setup, thoughtful UX and the rare combination of AI features plus open-source code as the headline strengths. On Reddit's r/selfhosted and r/SaaS, Postiz is named alongside Mixpost as the only viable open-source social media scheduler in 2026, with commenters singling out Bluesky, Mastodon, Reddit and Warpcast support as "rare" among scheduling tools.
The recurring complaints are real: deployment can be finicky on bare Node setups (multiple users on r/selfhosted ended up switching to the official Docker image), some users feel the $29 Standard tier is steep given gaps like bulk creation and channel-specific duplication for Pinterest, and on G2 a handful of recent reviews call out billing and support response times as rougher than what you get from Buffer. Mediocre at the edges, but the core product is doing the work.
Postiz hosted plans bill monthly (annual saves roughly 20%). The self-hosted Docker version is free under AGPL-3.0 with feature parity to the hosted edition.
| Plan | Price | Channels | Key Limits |
|---|---|---|---|
| Self-hosted | $0 | Unlimited | AGPL-3.0, run anywhere — you provide compute and storage |
| Standard | $29/mo | 5 | 1 user, 400 posts/mo, 20 AI images, 3 AI videos, public API, 2 webhooks |
| Team | $39/mo | 10 | Unlimited posts & team members, 100 AI images, 10 AI videos, RSS auto-post, 10 webhooks |
| Pro | $49/mo | 30 | Unlimited posts/team, 300 AI images, 30 AI videos, 30 webhooks |
| Ultimate | $99/mo | 100 | Unlimited posts/team, 500 AI images, 60 AI videos |
Every paid plan includes a 7-day free trial and Discord-based support.
Best for: Indie hackers, technical creators, dev-tooling startups and digital agencies that already live in n8n / Make.com / Zapier and want to add social scheduling to existing pipelines — or self-host the whole thing on a $5/month VPS. Also a strong fit for teams that need Bluesky, Mastodon, Reddit, Threads or Warpcast support, which most legacy schedulers either skip or treat as a paid add-on.
Not ideal for: Non-technical solo creators who just want to post to Instagram and X — Buffer's simpler UI will be friendlier. Enterprises that need phone support, granular SOC 2 audit logs or built-in social listening should still look at Hootsuite or Sprout Social.
Pros:
Cons:
If Postiz isn't the right fit, the closest alternatives are Buffer (cleanest UI, 11 networks, $6/channel/month entry plan but no real public API), Hootsuite (full enterprise stack with social listening but starts at $199/user/month) and Mixpost (the other open-source self-hosted option, fewer integrations and no public API). For mostly-X-and-LinkedIn workflows, Typefully remains the most polished single-purpose tool.
Yes — with a clear caveat. If you are a developer, indie hacker or technical marketer who wants to automate social posting from n8n, Make.com or your own scripts, Postiz is the highest-leverage option in 2026 at any price, and it is genuinely free if you self-host. If you are a non-technical creator with a Mac, a single brand and an Instagram-first workflow, Buffer's UI will save you more time than Postiz's open API ever could. We rate Postiz 87/100 — held back from a higher score by Standard-plan limits and Discord-only support, but earning its rating on the strength of 20+ channels, a real API on the entry plan and an MCP server that nobody else in this category ships.
