Postiz Alternative: 5 Options if You Mostly Post on X
Short answer: Postiz is a strong open-source scheduler for many networks at once. The usual reasons to look for a Postiz alternative are cost and focus: hosted plans start at $29 a month, and self-hosting means running a server and paying X yourself for every post. If X is your main channel, Buffer or Typefully are cheaper for a few posts a week, and Kalen fits if you write your posts with Claude or ChatGPT and want research and scoring as well as scheduling.
What is Postiz?
Postiz is an open-source social media scheduler. The code is public on GitHub, and you can either run it yourself or pay for the hosted version. Its pricing page lists:
- Many networks: X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Threads, Pinterest, Reddit, Bluesky, Mastodon, Discord and more.
- Unlimited posts on every hosted plan.
- AI tools: a copilot for writing, plus monthly allowances for AI images and videos on most plans.
- Agent access: a hosted MCP server, a CLI, a public API and webhooks on every plan.
- Teams with unlimited members from the Team plan up.
If you run social for a brand across many networks, or you want to self-host your scheduler, Postiz is a good pick.
How much does Postiz cost in 2026?
From Postiz’s pricing page, October 2026:
| Plan | Monthly | Yearly (per month) | Channels | Team members |
|---|---|---|---|---|
| Standard | $29 | $23 | 5 | No |
| Team | $39 | $31 | 10 | Unlimited |
| Pro | $49 | $39 | 30 | Unlimited |
| Ultimate | $99 | $79 | 100 | Unlimited |
Every hosted plan has a 7-day free trial. The self-hosted version has no software cost.
Why do people look for a Postiz alternative?
$29 is a lot for one X account. Standard covers 5 channels. If all you post to is X, you pay for four channels you don’t use.
Self-hosting isn’t free posting. Running Postiz yourself means a server you keep updated. To publish on X you also need your own X developer app, and since 2026 X bills that app for every post: $0.015 for a regular post and $0.20 for a post with a URL, according to X’s developer docs. See X API pricing per post.
Many networks, not X first. A tool built for a dozen networks treats X as one of them. X habits like putting the link in a first reply and mixing evergreen posts with posts about the day’s trends are yours to manage.
It doesn’t tell you what to post. Postiz helps you write and schedule. It doesn’t research what your niche is engaging with today or check a draft against your own best posts.
What are the best Postiz alternatives?
Prices checked October 2026. Confirm on each vendor’s page before you buy.
| Tool | Starting price | Free option | Networks | Best for |
|---|---|---|---|---|
| Buffer | $6/channel/mo | Free plan: 3 channels, 10 queued posts each | Many | A simple queue for a few accounts |
| Typefully | Creator $99/yr | Free plan: 10 posts/mo | X, LinkedIn, Threads, Bluesky, Mastodon, Substack | Writing threads in an editor |
| Publer | $5/mo for 1 account | Free plan, but not for X | Many | Cheap multi-network scheduling |
| X composer | Free | Yes | X only | A few posts a week |
| Kalen | $9/mo | No, 14-day trial | X only | People who write with AI and post daily |
Buffer
The classic queue. You set times once and posts fill the next slot. Pricing is per channel, so one X account is $6 a month. See Buffer Alternative and Buffer pricing.
Typefully
A writing-first scheduler with an editor built around threads and exact previews. Free for 10 posts a month, then Creator is billed yearly. See Typefully Alternative.
Publer
A low-cost multi-network scheduler. Its free plan excludes X, so X starts on Professional. See Publer Alternative.
X’s built-in scheduler
Free, inside the x.com composer, one post at a time. See How to Schedule Tweets.
Kalen
Kalen is X only and has no editor of his own. He connects to Claude, ChatGPT, Cursor or any AI with remote MCP:
- Every day he researches your niche: the day’s top posts for your keywords and X trends, and once a week the best posts of your reference accounts and of your own account.
- Your AI writes from that briefing into your open slots, about 40 posts a week by default.
- Every draft is scored from 0 to 100 with Jev against what works in your niche and your own best posts. Weak drafts go back for up to 3 rewrites.
- Nothing is scheduled until you say yes. Then he publishes through the official X API, with an optional first reply for your link.
How do Postiz and Kalen compare?
Postiz also has an MCP server, so you can schedule from an AI with either one. The difference is what comes with it.
| Postiz | Kalen | |
|---|---|---|
| Networks | 12+ | X only |
| Self-hosting | Yes, open source | No |
| Niche research | No | Daily top posts and trends, weekly reference accounts |
| Draft scoring | No | Every draft, 0 to 100, up to 3 rewrites |
| X API costs when you self-host | You pay X through your own app | Not applicable: Kalen pays X, covered by credits |
| Starting price | $29/mo, 7-day trial | $9/mo, 14-day trial |
Stay on Postiz if you post to several networks, need a team workspace, or want to own your install.
Choose Kalen if X is where you’re growing, you post daily, and deciding what to write is the slow part.
Kalen runs on credits: a post costs 1, or 2 with a first reply or a link. Starter is $9/mo (100 credits), Pro $29/mo (700) and Ultra $49/mo (1,500). Every plan starts with a 14-day free trial and 50 credits; cancel before it ends and nothing is charged. There is no free plan because X charges for every post published through its API.
Next step: connect Kalen to Claude, ChatGPT or Cursor, then ask for next week’s X posts. See the plans.
