Postiz is one of the best-known open-source social media schedulers. It covers 30+ platforms, can be self-hosted for free under an open-source license, and also offers a hosted version. If you're searching for an alternative, it's usually for one of a few specific reasons. Here are five worth comparing, and how to choose.
We make OneUp, so we've listed it first. We've tried to describe the others fairly, but features and pricing change, so confirm the details on each tool's own site.
Why people look for a Postiz alternative
- They don't want to run servers. Self-hosting is free, but you provide the server, keep it updated, and register your own developer apps with each social network. Postiz notes that approvals from networks like Meta and YouTube can take a long time.
- They want a hosted tool priced differently. Postiz's hosted plans are priced by channel count in steps (5, 10, 30, then 100), with a 7-day trial rather than a permanent free tier. The entry plan doesn't include team members.
- They want a different feature mix, such as approvals, a social inbox, or deeper analytics.
- They want a free plan to start on.
1. OneUp
OneUp is a hosted scheduler, so there's nothing to install and OneUp handles the connections to each network. It covers a dozen-plus networks, including Instagram, Facebook, TikTok, X, LinkedIn, Pinterest, YouTube, Snapchat, Threads, Bluesky, Discord, Reddit, and Google Business Profile.
What it adds beyond scheduling:
- Crossposting workflows and repeating posts for evergreen content
- Bulk upload from CSV, Google Drive, Dropbox, or a Google Sheet
- Post approvals, including for clients who aren't OneUp users, and view-only calendar links
- A social inbox, comment replies, and DM automation for Instagram and Facebook
- Analytics reports you can download or email on a schedule
- A REST API, an MCP server, and setup for terminal coding agents
Trade-offs: OneUp isn't open source, and it supports fewer networks than Postiz's 30+. It has a 7-day free trial but no permanent free plan.
Best for: teams that want a managed tool with broad coverage, automation, and client workflows.
2. Buffer
Buffer is a simple hosted scheduler with a free plan for a small number of channels and per-channel pricing. It also offers an MCP server on every plan, so you can connect AI assistants.
Best for: solo creators and small teams who want something simple to start with.
3. Metricool
Metricool combines scheduling with strong analytics and reporting, has a free tier, and offers an MCP server.
Best for: marketers who care as much about analytics as publishing.
4. Publer
Publer is a hosted scheduler with bulk publishing, a free tier, and per-account pricing that suits people who connect many accounts. It includes networks like Bluesky and Mastodon.
Best for: users who want per-account pricing and flexible workspaces.
5. Mixpost
Mixpost is the closest match if you want to keep self-hosting. It's a self-hosted tool sold with a one-time license, with a free Lite edition and a hosted cloud option.
Best for: self-hosters who like Postiz's approach but prefer a one-time license.
How to choose
- Want to stop managing servers: a hosted tool like OneUp, Buffer, Metricool, or Publer
- Want a free plan: Buffer, Metricool, or Publer
- Want to keep self-hosting: Mixpost
- Want automation, approvals, and a wide network list in one tool: OneUp
