Postline vs Buffer
Buffer is a general social media tool for many networks and post types. Postline does one job: it posts short videos from a queue to YouTube, Facebook and Instagram. Here is how they differ, including where Buffer is the better pick.
| Feature | Postline | Buffer |
|---|---|---|
| How you pay | Per channel (one brand with all its accounts) | Per social account |
| Entry price | $7.50/mo on yearly billing, Starter (3 channels) | $5/mo per account on yearly billing, Essentials |
| 3 brands on 3 platforms | $7.50/mo | $45/mo (9 accounts) |
| Free plan | No, 14-day trial | Yes: 3 accounts, 10 scheduled posts each |
| Free trial | 14 days | 14 days on paid plans |
| Networks | YouTube, Facebook, Instagram. TikTok coming | 12, including LinkedIn, X, Threads, Pinterest and TikTok |
| Post types | Short video | Text, images and video |
| API | Yes, on every plan | Yes, with monthly request limits |
Pick Postline if
- You run several video brands and paying per account adds up.
- You post every day from a batch of finished videos and want a queue, not a calendar.
- Your videos come from a script or an AI agent, and you want them queued through an API.
- You want your files in your own storage and Facebook posting through your own app.
Pick Buffer if
- You need LinkedIn, X, Threads, Pinterest or TikTok today.
- You post text and images as well as video.
- You have one or two accounts and the free plan is enough.
- You want to start in a few minutes. Postline asks for more setup than most schedulers: your own storage bucket (about 5 minutes) and, for Facebook and Instagram, your own Meta app (about 20). The guides walk through both with screenshots.
