Run a full campaign before you install anything
This is the GroupBlaster extension, rebuilt in your browser with sample groups. Pick your line of work, click through all five steps and watch a post go out group by group — with the paid features unlocked so you see the whole flow.
- No install, no sign-up, nothing is posted to Facebook.
- Sample groups and sample posts stand in for yours.
- Paid-plan features are unlocked in this demo so you can see the full flow.
Try it the way you'd actually use it
Pick your line of work — the groups, the post and the benefits all change with it. Then click through the five steps inside a replica of the extension.
Marketing teams & agencies. You post the same client update to every community your agency belongs to — and each one has to read like it belongs there.
Step 1 of 5
Find every group you're already in
GroupBlaster opens your Facebook groups and scans them to the bottom, then lists every group you've joined with its member count. No spreadsheet, no copy-paste — and scanning needs no account.
One scan replaces the scrolling you do by hand every time you want to post somewhere.

Your Groups
No groups collected yet
Run the scanner first — it collects every group your account has joined, then you pick the ones to post to.
Simulation — sample groups, nothing posted to Facebook. The run is shown at accelerated speed; in the extension consecutive posts stay at least 15 seconds apart.
What that changes for Marketing teams & agencies
One campaign, every community
Write the client update once, send it to each group you picked, and keep working while the run finishes.
Wording that varies group to group
You write the alternates in braces — each group sees a different version, so it never reads like one blast copy-pasted everywhere.
Every group reports back
Posted, awaiting approval, or skipped with the reason. Nothing fails silently while the client is waiting.
Run your own numbers
Posting by hand means open the group, paste, fix the wording, add photos, publish, next tab. Set what that actually costs you and see what changes.
Manual posting means opening each group, pasting, attaching media, and waiting — about 4 minutes per post at your pace.
That's 2.4 hrs back every month from 43 posts — write once, pick groups, set a schedule.
Reclaim those hours — freeYou just used the paid plan
The demo runs unlocked so nothing gets in the way of the walkthrough. Here is exactly which half belongs to which plan.
Try the whole habit
- 5 campaigns and 10 posts a month
- Scan your groups — no account needed
- Spintax alternates you write yourself
- Fill only: GroupBlaster types it, you press Publish
Sign in with Google to create a campaign or start a run — scanning your groups never needs an account.
What the demo unlocked
- Auto publish — the mode the demo runs in
- Confirm each — review before it goes out
- Scheduling & recurring cadences
- Randomized pacing inside your chosen range
On the free plan the same run still works — it just stops at the composer and waits for your Publish click on each group.
