PostInkBuffer alternative
A Buffer alternative made for posting on X
Buffer schedules to a dozen networks. If X is the only one you care about, PostInk is built around it. Drafts and replies in your voice, threads, a calendar and posting hours, for $3.99 once.
The short answer
Choose Buffer if you post to Instagram, LinkedIn, TikTok and others, work with a team, or need posts to go out while your computer is off. Its free plan works well for light use. Choose PostInk if X is your network and writing is the hard part. It drafts posts and replies that sound like you, throws out the ones that read as AI, and schedules what you approve.

- your team needs approvals and access levels
- you schedule from your phone
- posts must go out while your computer is off
PostInk is the better choice if
- X is the network you post on
- writing slows you down more than scheduling does
- you want replies drafted inside X, in your voice
- you’d prefer one $3.99 payment to a per-channel plan
Questions
Is Buffer free?
Buffer has a free plan for up to 3 channels, with 10 scheduled posts per channel and one threaded post. Paid plans start at $6 per channel a month, or $5 billed yearly. Prices as listed on 29 October 2026.
Is PostInk a full Buffer replacement?
Only if X is the one network you post to. Buffer schedules to twelve networks and offers team plans and mobile apps. PostInk is made for X alone.
What does PostInk do that Buffer does not?
It drafts posts, threads and replies in your own voice, learned from what you’ve written on X. It throws out drafts with the phrasing that makes text sound generated. And it drafts replies right inside X’s reply box.
Does PostInk need my computer on to post?
Yes. PostInk posts from your own browser, so Chrome needs to be open at post time. Posts that came due while it was closed go out one at a time when it opens again. Buffer posts from its own servers, so it doesn’t have this limit.
