What NinjaPoster is
NinjaPoster is a Facebook group auto poster built around a web dashboard. You create an account, install its Chrome extension and sign in; NinjaPoster fetches the groups you belong to, and the campaigns you schedule in the dashboard are posted one group at a time through your own logged-in browser. Its site says it accesses Facebook “using your device, not our servers”.
There is one plan, NinjaPoster Pro, at $37 a month with every feature: posting to joined and managed groups as a profile or a Page, text, link, image and video posts, repeating schedules, delays, auto-pause and Spintax, RSS posting, AI post creation and a per-group AI rewrite, scheduling from a phone, an automatic first comment, group categories and a training academy. Its pricing page says the price will rise to $57 a month, and that anyone who joins now keeps $37.
No trial is listed: the first payment can be refunded within 7 days, and renewals cannot. Two other dashboard posters sit either side of its price: PostPartner at $29 a month and PilotPoster at $47.
What NinjaPoster’s comparison page says about MultiGroupPoster
NinjaPoster publishes its own “NinjaPoster vs MultiGroupPoster” page. Checked on 2 October 2026, its table gives MultiGroupPoster a cross for “AI post creation + spintax”, rates its price transparency as “Varies” and calls its posting to joined groups “Inconsistent”.
Two of those are wrong. Spintax with a live preview is built into MultiGroupPoster’s Variation Builder, shown above, so only the AI half of that cross holds; and its price is published: $9.99 a month or $69.99 a year. The page gives no source for “Inconsistent”; posting to groups you joined is what MultiGroupPoster is built for.
The rest of its table is fair: MultiGroupPoster has no AI writer, no RSS posting, no web dashboard and no scheduling from a phone. If you need those, they are real reasons to choose NinjaPoster.

Which should you pick?
Pick MultiGroupPoster if…
- You want the core job — one post to many joined groups, on a schedule — for $9.99 a month.
- You want to try it on your own groups before paying.
- You vary photos as well as text, or reshare existing posts.
Pick NinjaPoster if…
- You run a blog or a Page and want RSS to send each new post to your groups.
- You want AI to write the posts, or to queue campaigns from your phone.
Migrating across
- Install MultiGroupPoster and sign in with Google; NinjaPoster can stay installed while you compare.
- Let MultiGroupPoster read the groups you belong to, so there is no list to export.
- Recreate your group categories as lists and paste your posts in; standard {option|option} Spintax works unchanged.
- Run a small campaign on 5–10 groups first, and never schedule both tools against the same groups.
Frequently asked questions
Can NinjaPoster post to Facebook groups I joined?
Yes. NinjaPoster is a browser extension that posts from your own logged-in Facebook session, which is what reaches groups you joined. Cloud schedulers such as Buffer and Hootsuite cannot, because Meta removed the publish_to_groups permission in April 2024 — and it never covered groups you merely joined.
How much does NinjaPoster cost?
One plan, NinjaPoster Pro, at $37 a month, according to ninjaposter.io on 2 October 2026; its pricing page says the price will rise to $57 for new subscribers. No trial is listed, and the first payment can be refunded within 7 days. MultiGroupPoster is $9.99 a month or $69.99 a year after 6 free posts.
Is NinjaPoster’s comparison with MultiGroupPoster accurate?
Partly. It is right that MultiGroupPoster has no AI writer, RSS posting, web dashboard or phone scheduling. It is wrong that MultiGroupPoster lacks Spintax, which is built in with a live preview, and MultiGroupPoster’s prices are published: $9.99 a month or $69.99 a year.
Can NinjaPoster post as a Page?
Yes. Its site lists posting as a profile or as a Page. MultiGroupPoster can also post in groups as a Page you manage, and on the feed of a Page you manage.
How hard is it to switch from NinjaPoster?
Install MultiGroupPoster and sign in with Google; NinjaPoster can stay installed while you compare. Let MultiGroupPoster read the groups you belong to, so there is no list to export. Recreate your group categories as lists and paste your posts in; standard {option|option} Spintax works unchanged. Run a small campaign on 5–10 groups first, and never schedule both tools against the same groups.
Will either tool get my Facebook account restricted?
Neither tool changes what Facebook flags — pacing and content variation do. Randomized pauses of a few minutes after every few posts, 50–100 posts a day on an account older than twelve months, varied text per group and media attached is the safe range with any tool. Aggressive settings will flag an account regardless of which tool produced them.
