How each one posts
Both work inside the Facebook tab you are already logged in to, which is why both can reach groups you only joined. Neither uses the public Groups API that Meta retired in April 2024.
Each also offers two ways to publish. Group Posting Pro describes an “API Speed Mode” that sends requests to Facebook’s internal web endpoints, and a Classic mode that fills in and submits the visible composer. MultiGroupPoster’s Fast method uses the same internal request path the Facebook site itself uses, and its Safe method drives the real composer.
A correction: earlier versions of this page said Group Posting Pro only drove the page (DOM automation) and broke more easily than MultiGroupPoster. Its own documentation describes both methods, so that claim was wrong and we have removed it.
What each one costs
Group Posting Pro sells three plans in euros. Lite is free for good: 5 group-posts a day, five AI uses in total, no schedules. Plus is €69 a year, sold yearly only: unlimited posting, one-time, daily and weekly schedules, and first comments. Pro is €24 a month, €39 a quarter, €118.80 a year or €279 once, and adds AI writing, campaigns, Lead Radar, monthly schedules and cloud backup. A €1, six-day Pro trial renews at €24 a month.
MultiGroupPoster has one paid plan in US dollars, with every feature: $9.99 a month or $69.99 a year, after 6 free posts. A first purchase has a 7-day money-back guarantee; Group Posting Pro refunds a paid plan while its activation key is unused.
Group Posting Pro not working? What to check first
When Group Posting Pro stops posting, the cause is usually one of four things: a Facebook change the extension has not caught up with yet, one of its two posting modes failing while the other still works, a group that holds or refuses the post, or Facebook limiting the account. The extension itself is maintained: version 2.11.21 shipped on 15 October 2026, and on 18 October its Chrome Web Store listing showed 4.3 stars from 133 ratings and 4,000 users.
Its recent store reviews describe the failures people hit. One from 7 October 2026 reports a Classic mode error after two or three posts; one from July 2026 reports that posts with a background colour stop working when Spintax is in the text; one from 17 October 2026 reports a Facebook warning about automated behaviour. If one mode fails, switch to the other and test a plain post without a background colour or Spintax. A warning from Facebook is a different problem: no posting mode fixes it, while fewer groups per hour and varied wording do.
The same checks apply to any group poster, MultiGroupPoster included. Why a Facebook group poster stops working walks through them in order, from your account to the result in each group.

Where each one wins
Where MultiGroupPoster wins
- Lower monthly price: $9.99, against €24 for Group Posting Pro’s Pro plan billed monthly — its cheaper Plus plan is sold yearly only.
- One plan with everything in it: monthly schedules, first comments, Share to groups and Image Sets.
- Image Sets rotate a different set of photos to each group, alongside Spintax for the text.
- A 4.9 rating from 114+ Chrome Web Store ratings, against 4.3 from 133 (both checked 18 October 2026).
Where Group Posting Pro wins
- A free-forever Lite plan: 5 group-posts a day with no card. MultiGroupPoster’s free allowance is 6 posts, once.
- A built-in AI writer on Pro (8 tones, A/B/C/D variations). MultiGroupPoster has none — you use Spintax, or paste text from an AI tool.
- Lead Radar watches up to 25 of your groups for buyer phrases and drafts replies; MultiGroupPoster does not monitor groups.
- Multi-step campaigns, AI group discovery, cloud backup and a €279 lifetime licence, none of which MultiGroupPoster offers.
- More users: 4,000 against 3,000+.
Which should you pick?
Pick MultiGroupPoster if…
- You want unlimited posting with schedules and first comments for $9.99 a month, without committing to a year.
- You vary photos as well as text across groups.
- You write your own posts, or draft them in ChatGPT, and do not need an AI writer inside the extension.
Pick Group Posting Pro if…
- Five group-posts a day covers you and you want to stay on a free plan.
- You want AI-written variations, keyword alerts for leads or multi-step campaigns in the same tool.
- You would rather pay once (€279) than subscribe.
Migrating across
- Install MultiGroupPoster and sign in with Google. Group Posting Pro can stay installed while you compare.
- Your groups import from your own Facebook memberships, so there is nothing to export from Group Posting Pro.
- Rebuild collections as tagged lists; templates written in standard {option|option} Spintax paste straight in.
- Test on a handful of groups first, and do not run both tools on the same groups at the same time.
Frequently asked questions
Can Group Posting Pro post to Facebook groups I joined?
Yes. Group Posting Pro 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.
Is Group Posting Pro free?
Partly. Its Lite plan is free forever, with 5 group-posts a day, no card and five AI uses in total; schedules, campaigns and ongoing AI need Plus (€69 a year) or Pro (€24 a month, or €118.80 a year). Figures from groupposting.com/pricing on 26 September 2026.
Does Group Posting Pro post through the API or the page?
Both. Its site describes an “API Speed Mode” that sends requests to Facebook’s internal web endpoints, and a Classic mode that fills in the visible composer. MultiGroupPoster also offers two methods, Fast and Safe. Neither uses the public Groups API that Meta retired in April 2024.
Does MultiGroupPoster have an AI writer like Group Posting Pro?
No. MultiGroupPoster varies text with Spintax and photos with Image Sets; for AI drafts, paste text from any AI tool into the editor. If writing inside the extension matters to you, Group Posting Pro’s Pro plan includes an AI writer.
Which is cheaper, Group Posting Pro or MultiGroupPoster?
Month to month, MultiGroupPoster: $9.99 against €24 for Group Posting Pro’s Pro plan. Per year, MultiGroupPoster is $69.99, Group Posting Pro Plus €69 and Pro €118.80. Group Posting Pro also has a free plan and a €279 lifetime licence; MultiGroupPoster has neither.
Is GroupPosting the same as Group Posting Pro?
Yes. The extension is listed on the Chrome Web Store as Group Posting PRO and its website is groupposting.com, so people search for it under both names. This page calls it Group Posting Pro throughout.
Why is Group Posting Pro not working?
Usually one of four causes: a Facebook change the extension has not caught up with, one of its two modes (API Speed Mode or Classic) failing while the other works, a group holding or refusing the post, or Facebook limiting the account. Switch modes, test a plain post without a background colour or Spintax, and check the result group by group. Version 2.11.21 shipped on 15 October 2026, so the tool is maintained.
How hard is it to switch from Group Posting Pro?
Install MultiGroupPoster and sign in with Google. Group Posting Pro can stay installed while you compare. Your groups import from your own Facebook memberships, so there is nothing to export from Group Posting Pro. Rebuild collections as tagged lists; templates written in standard {option|option} Spintax paste straight in. Test on a handful of groups first, and do not run both tools on the same groups at the same time.
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.
