Multigroup Poster is a Chrome extension that lets marketers, agencies, and small business owners publish the same content to dozens of Facebook groups in a single click — directly from their own browser. Instead of opening fifty tabs and copy-pasting the same message all morning, users write the post once, select a saved group list, and let the extension cycle through every group with randomized delays in the background.
The product is built for operators who rely on Facebook groups as a primary distribution channel: real estate agents posting daily listings to local buy/sell communities, recruiters distributing job openings across industry and city groups, agencies managing posting calendars for multiple clients, coaches and consultants running lead-generation content, and e-commerce sellers cross-listing products. A typical active user saves 7 to 10 hours of manual clicking per week.
Core capabilities:
Bulk posting to unlimited Facebook groups from saved, reusable group lists
Built-in scheduler for queuing posts to a specific date and time
Spintax variation engine that produces a uniquely worded post for every group from a single template, which is the single most important technique for sustainable, natural-looking posting cadence
Configurable randomized delays (30 to 300 seconds) and daily posting caps
Full media support: single images, multi-image carousels, native video, link previews, and colored-background text posts
Posting as a Page or Profile, multi-account support, and detailed run history with per-group success and failure logging
Auto-retry on transient network failures
Multigroup Poster runs entirely inside the user's own Chrome browser using their existing Facebook session. No Facebook passwords are ever requested or stored, no post content is transmitted to third-party servers, and all group lists, drafts, and scheduling state are stored locally in chrome.storage. The extension is built on Manifest V3 and runs on every Chromium-based browser, including Chrome, Microsoft Edge, Brave, Opera, Vivaldi, and Arc.
A free trial is available with no credit card required. Paid plans unlock unlimited posting volume, larger saved lists, longer run history, and multi-account support.
