MultiGroupPoster is a Chrome extension for marketers, agencies, and small businesses who need to post the same content to many Facebook groups — without spending two hours every morning doing it by hand, one group at a time.
It runs inside your own logged-in Facebook session and publishes your post to the groups you've joined (not just groups you admin) in a single click. Because it works from your own browser instead of a remote server, it's one of the few tools that still works for Facebook groups after Meta removed the publish_to_groups API for third-party apps in April 2024 — the change that ended cloud-based group posting for schedulers like Buffer and Hootsuite.
What makes it stand out:
• Bulk-post to 100+ Facebook groups in one click
• Spintax text variation AND image spintax (a different image set per group) — so every post is unique and nothing looks copy-pasted
• Schedule campaigns once, daily, weekly, or monthly
• Automatic first comment (drop your link safely in the comments)
• Post as your personal profile or a Page you manage
• Reusable group lists, randomized human-paced delays, and per-group results
• A direct-API engine that's far more resilient to Facebook UI changes than DOM-scraper tools
It's a lower-cost, safety-focused alternative to tools like PilotPoster, SafePoster, Group Posting PRO, and the discontinued FewFeed. A free tier lets you try it before upgrading to unlimited posting.
Works in Chrome, Edge, and Brave (any Chromium browser) on Mac, Windows, Linux, and Chromebook.
