GroupBlaster
Auto pilot your single post to all of your Facebook groups
GroupBlaster is a Chrome extension for publishing to the Facebook Groups you've already joined — one post at a time, at a pace you set. Scan your groups once, then build named campaigns: each one holds its own post, its own group set, and its own schedule. Choose confirm mode to review and approve every post before it goes live, or auto mode to let the run proceed group by group. Pause, resume, or stop any run mid-flight, and see every published post linked back in your history. It's scoped per logged-in Facebook account, stores no Facebook credentials, and works with a free tier of 5 campaigns and 10 posts a month. Sign-in is required to create or start a campaign; group scanning is not.
Features
- Group discovery — scan the Facebook Groups you've joined, no sign-in needed
- Named campaigns, each with its own post, group set, and schedule
- Confirm mode: review and approve each post before it publishes
- Auto mode: runs group by group while you watch (Pro)
- Scheduling with per-campaign cadences and a recurring scheduler (Pro)
- Pause, resume, or stop a run at any time
- 15-second minimum delay between posts, with adjustable pacing
- Spintax text variations you write yourself — every plan, no AI rewriting
- Per-account scoping — switch Facebook accounts without mixing data
- Posting history with "View post" links for every published entry
- Free tier: 5 campaigns and 10 posts per month
Use Cases
- Real estate agents — publish a new listing to every local buy/sell/rent group they're in, one campaign per listing drop
- Small business owners — announce a promotion, event, or new product across neighborhood and niche groups without block-copying all afternoon
- Community marketers — run recurring announcements (weekly deals, newsletter drops) on a schedule per group set
- Recruiters — share a job posting across industry and city groups, approving each one before it goes live
- Solopreneurs & coaches — turn one piece of content into a week of group distribution, filling each composer and posting on their own schedule
- Agency / freelancers — keep client campaigns separate: each campaign owns its post, groups, and cadence, so nothing bleeds between accounts
- Anyone wary of blind automation — confirm mode fills the post and waits for your approval on every group, so you see exactly what goes out and where
- Multi-account operators — switch between logged-in Facebook accounts and each

I built GroupBlaster because I was tired of two things: copy-pasting the same post into group after group (I do have a business besides from being an engineer and I leverage Facebook groups to promote my products), and bulk tools that blast everything out while you're not looking. The second one scared me more. When a tool publishes on your behalf, you want to see what it's doing — and be able to stop it. So GroupBlaster is built around approval instead of autopilot: it fills the post, you check it, you let it go. Every campaign keeps its own groups and schedule, and there's always a pause button in reach. The free tier is deliberately generous (5 campaigns, 10 posts a month) because I'd rather you try it properly than hit a wall in five minutes. I'd love to hear what you'd build with it — or what's missing.
