About
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 broadcasting new listings across neighborhood groups
• Community managers pushing chapter or branch announcements
• Marketplace sellers refreshing buy-and-sell posts
• Recruiters sharing roles across industry groups
• Event organizers and promoters spreading tour dates and launches
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.
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.
