The short answer
The best Zernio alternative for X is OpenTweet once you post more than about 145 links a month: Advanced is a flat $29/mo with 10 link posts a day, while Zernio passes on X's $0.20 for each one.
Below that volume, stay on Zernio. Its first 2 accounts are free, and at X's rates 100 plain posts cost $1.50 a month. Zernio also covers 16 networks to OpenTweet's 3. OpenTweet is the better fit if you want a predictable bill on X, an AI writer that learns your voice, and RSS or API connectors that turn a feed into posts.
Connecting X needs a card, even on the free tier
Zernio's X page says: "Because every call has a cost, connecting an X account needs a payment method on file, even on the free tier." The rates are X's own with no markup, so Zernio is not overcharging. Your X bill simply grows with every post.Zernio pricing in 2026

Zernio vs OpenTweet: the monthly cost on X
One X account, posts only, no reads. Zernio's account fee is $0 here. We worked these out from each tool's published prices.
| Monthly volume | Zernio | OpenTweet | Cheaper |
|---|---|---|---|
| 100 plain posts | $1.50 | $19.99 (Pro) | Zernio |
| 600 plain posts (20 a day) | $9 | $19.99 (Pro) | Zernio |
| 30 link posts (1 a day) | $6 | $19.99 (Pro) | Zernio |
| 145 link posts | $29 | $29 (Advanced) | Same |
| 300 link posts (10 a day) | $60 | $29 (Advanced) | OpenTweet |
| 3,000 plain posts (100 a day) | $45 | $29 (Advanced) | OpenTweet |
| 600 link posts (20 a day) | $120 | $49 (Agency) | OpenTweet |
The result turns on links, because X charges about 13 times more for a post with a URL. On Zernio, reads add $0.005 each, which matters if your agent checks timelines before it posts.

How to move from Zernio to OpenTweet
Add up last month's X fees
Check your Zernio bill. If X fees are under $19.99 and you do not need the AI writer or connectors, staying is the cheaper choice.
Connect your accounts
Start the trial and connect each X, Bluesky or LinkedIn account with a normal login. Pro has 1 X account, Advanced 3, Agency 10.
Move your agents and scripts
Replace https://mcp.zernio.com/mcp with https://mcp.opentweet.io/mcp. In scripts, call POST https://opentweet.io/api/v1/posts with an ot_ key.
Import what is queued
OpenTweet imports JSON or CSV, and the CSV importer reads date and time columns. Pause the Zernio queue first so nothing posts twice.

Is Zernio free for X?
The account fee is free for your first 2 accounts, but X calls are not. Zernio charges $0.015 per post and $0.20 per post with a link, and its X page says connecting an X account needs a payment method on file, even on the free tier.
Does Zernio charge $0.20 on top of $0.015 for a link post?
Its pages list $0.20 as the price of a post with a URL and $0.015 as the price of a post, so we read $0.20 as replacing $0.015. No page we read says the two are added together.

With one X account, at about 145 link posts a month on Advanced ($29 divided by $0.20). For plain posts, Zernio stays cheaper far longer: Pro at $19.99 only breaks even at about 1,330 plain posts a month.
Does Zernio have an MCP server?
Yes. Its llms.txt lists a hosted server at https://mcp.zernio.com/mcp with OAuth or an API key. The server is free, and tool calls bill like the API requests behind them. OpenTweet's hosted server at https://mcp.opentweet.io/mcp has 43 tools and no per-call X fee.
