How we grade them
| 2.4GPAPostizFair | 2.4GPAZernioFair | |
|---|---|---|
| Value for money | C$23 a month on yearly billing ($29 monthly) for 5 channels, close to the category's $29 middle. The $0 self-hosted edition needs your own server. | B2 accounts free, then $6 per account for accounts 3 to 10, so five accounts cost $18, near the $14 cheaper quarter, and it gets cheaper per account after 10. |
| Free plan and trial | CThe self-hosted edition is free, but you run it; hosted has a 7-day trial and no free plan. The listing doesn't say if the trial needs a card. | BThe first 2 connected accounts are free with every feature and no card, enough for one person or a prototype. |
| Features | BCalendar, repeats and delays, plugs, AI, analytics, an API, webhooks and MCP. Standard has no team members. | CPosting and scheduling API, comments, DMs, analytics, webhooks, ads and phone numbers. The listing itself says it isn't a ready-made content calendar. |
| Ease of use | CNo store rating on record. Hosted is quick to set up, though self-hosting is Docker work. | DNo store rating on record. It's an API: you build against it with SDKs, so it needs a developer. |
| Platforms and integrations | BWeb, with Facebook, Instagram, LinkedIn, X, TikTok, YouTube, Pinterest, Reddit and an API. No phone apps. | BWeb dashboard and an API with SDKs, an MCP server, WordPress and about a dozen networks. No desktop or phone app. |
| Best for | a posting API you can host yourself | a posting API for apps and AI agents |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
