Facebook Groups Auto Poster - GroupBlaster

Post to your Facebook groups in minutes — no more tab-hopping. GroupBlaster is a Chrome extension for people who manage listings, announcements, or community updates across many Facebook Groups. Write your post once, pick the groups, and publish with full control over how much automation you allow — and on a paid plan, let a schedule dispatch it for you. HOW IT WORKS 1. Collect your groups — Scan all my groups opens your Facebook groups page and collects the groups you belong to, locally in your browser. Or tick Select on any group as you browse. 2. Create campaigns — Save named campaigns for the posts you publish regularly. Each campaign owns its own post content, its own group set, and its own schedule — nothing leaks between campaigns. Free includes up to 5 campaigns. 3. Schedule — Give each campaign its own cadence: Once, Daily, Weekly, or Monthly. Morning and evening campaigns can run side by side. Scheduling is a Pro feature. 4. Publish — Run a campaign now, or let the schedule dispatch it. Groups are processed one by one with conservative, configurable delays. PUBLISH MODES — YOU STAY IN CONTROL • Manual post (Free) — Photo and caption are filled for you; you click Post on Facebook yourself, then confirm before it continues to the next group. • Confirm each group (Pro) — Review every filled post and approve or skip group by group; approving posts for you. • Auto publish (Pro) — Posts are clicked automatically after a short safety delay. Optional randomized pacing (Pro) varies the wait between groups — 5 seconds, then 8, then 6 — within a range you set. The campaign stops immediately if Facebook shows a warning, CAPTCHA, login challenge, or restriction and asks you to step in. Live progress, a countdown to the next group, and toast updates keep you oriented — nothing ever looks frozen. BUILT FOR PEOPLE WHO POST TO MANY GROUPS Real-estate agents share new listings with neighborhood groups, community managers send chapter or branch announcements, marketplace sellers keep buy-and-sell posts fresh, recruiters post roles to industry groups, and event organizers spread tour dates and launches. If your posts have to reach more than one group, GroupBlaster is built for you. MULTIPLE FACEBOOK ACCOUNTS Everything is scoped per logged-in Facebook account. Groups, campaigns, schedules, and progress swap with the account, so managing several profiles never mixes your data. Identity is read from the page you already have open — nothing more. SIDE PANEL MODE Open GroupBlaster in Chrome's side panel and keep Facebook visible in the same window while you publish. OFFLINE-FRIENDLY, LOCAL-FIRST Your groups, campaigns, drafts, and schedules live in your browser's extension storage. Once you have signed in, the extension keeps working with no network; usage updates queue and sync when you are back. SAFE BY DESIGN • You log into Facebook normally — no authentication bypass, ever. • Only information your own session can already see is read. • No hidden APIs, no CAPTCHA or anti-bot circumvention, no detection evasion. • Your Facebook password, cookies, session tokens, and private messages are never read or stored. • Pacing floors (at least 15 seconds between posts) are enforced in code — randomized pacing varies gaps within your chosen range but never dips below that floor. • You approve publishing — every mode keeps a human in the loop. • Built-in spintax gives every group its own wording — write {variations|variants} once, and each group receives a different reading of your post. • Stuck for wording? The editor can open ChatGPT with your draft so you can write the variations yourself and paste them back — GroupBlaster never rewrites your post. PRICING • Free — 5 campaigns, 10 posts per month, Manual mode. No scheduling. • Monthly $5.99 — unlimited campaigns and posts, all modes, full scheduling, and randomized pacing. • Annual $57.60 — same as Monthly, 20% off. All paid plans include a 7-day free trial. Billing and cancellation are self-service. You sign in with Google to create a campaign and start a run — your plan and monthly post allowance are tied to that account, so a Pro upgrade follows you to any computer you sign in on. Scanning your groups needs no sign-in, and it is separate from Facebook: GroupBlaster never asks for your Facebook password. Start free — install GroupBlaster, hit Scan all my groups, and send your next announcement group by group, at a human pace.
