Posting to X with PostOnly
X is the one network that costs extra: posting needs an active X Posting subscription, from $4.99 a month. Everything else in PostOnly stays free for your first two accounts.
Posts go out with a 280-character counter, up to four images, and automatic reply-chain threading when you write past the limit.
How to connect X
- In PostOnly choose Add Account → X.
- Enter a display name.
- Click Sign in with X. X opens in your browser.
- Approve PostOnly and return to the app.
- Subscribe to X Posting from the paywall when PostOnly asks.
Good to know
- The subscription is billed separately from Multiple Accounts.
- Posts go out through PostOnly's own proxy so your X token is never used without an active subscription.
X questions
Why does X cost extra?
X charges developers for API access per request. The X Posting subscription, from $4.99 a month, covers that cost and nothing more. Every other network's API is free to use, so every other network is covered by the one-time purchase.
