How does PostSnag work?

PostSnag works by reading the public posts already loading in your own signed-in Facebook session as you scroll, saving them to your browser, then sending them to your dashboard the moment you click Export To Dashboard, where you sort, analyze, and export them.

Nothing happens until you act. PostSnag doesn't run in the background when you're not on Facebook, and it doesn't send anything to your dashboard until you click the export button yourself. Here is exactly what happens at each stage.

The three stages: capture, export, analyze

Every use of PostSnag moves through the same three stages:

1. Capture. You scroll a Facebook profile, Page, or group. PostSnag reads the public posts loading on your screen and saves them to your browser.

2. Export. You click Export To Dashboard. PostSnag sends your captured posts to your PostSnag account.

3. Analyze. You work in the dashboard: sort, filter, run Analytics, save to Bookmarks or Folders, and export a file.

Stage 1: The extension captures posts as you scroll

Open any Facebook profile, Page, or group and the PostSnag panel appears. As you scroll, PostSnag reads each public post two ways: it reads the same data Facebook's own page already loads for you (the post text, engagement numbers, and timestamps Facebook sends to your browser), and it reads what's actually rendered on the page as a backup, in case a post's full data didn't come through that first way. Between the two, PostSnag builds a complete picture of each post without ever asking Facebook for anything beyond what your own browsing already requests.

You'll see this happening in real time. The panel shows a Collected count that climbs as posts load, and a status pill that reads Capturing while a pass is active and Synced once it settles. A post you've already captured won't be double-counted even if it scrolls back into view, so scrolling back up over posts you've already passed is safe.

At this stage, everything stays on your device. Capturing while you scroll only ever saves posts to your own browser's local storage. Nothing reaches PostSnag's servers, and nothing reaches your dashboard, until you take the next step.

Stage 2: Export To Dashboard sends your capture to your account

When you're ready, click Export To Dashboard in the panel. This does two things: it sends the profile itself (name, avatar, and other public details) and every post you've captured for it up to your PostSnag account, and it opens your dashboard in a new tab, already signed in.

If you've captured a large number of posts, PostSnag sends them up in the background in the same click, so a big capture doesn't stall or time out. You don't need to wait around watching a progress bar; the new tab opens as soon as the sync starts.

If you're signed out, the button reads Sign Up To Export instead, since PostSnag needs somewhere to send your captured posts.

Stage 3: The dashboard is where you sort, analyze, and export

Your dashboard at app.postsnag.com organizes everything you've exported. A captured profile gets its own page with:

• Filters and sort, including type chips for All, Video, Photo, Album, Link, and Text (Reels fold into Video), a search box, a Sources filter when the profile includes group-tagged posts, a date range (Last 7, 30, or 90 days, or All time), and sort by Facebook's own order, most reactions, comments, or shares.

• Analytics, showing engagement totals and averages, the mix of post types, posting patterns by day of week, and top-performing posts.

• Bookmarks and Folders, so you can save individual posts or profiles and group them into named collections.

• Discovery, a shared feed of standout posts across every profile the PostSnag community has captured, not just your own.

• Export, where you download a Markdown or CSV file of the posts you're viewing. These files carry each post's reaction total; the full like, love, haha, wow, sad, and angry breakdown stays viewable in the panel and Analytics, not in the downloaded file.

Why this approach is safe and reliable

PostSnag never uses proxies, fake accounts, or Facebook's official API to get this data. It reads what your own logged-in session already receives as you browse normally, the same way your browser would whether PostSnag was installed or not. It never posts, likes, comments, messages, or follows anyone on your behalf. See Is PostSnag safe to use? for the full breakdown.

What happens if you don't export right away

Captured posts don't disappear if you close the tab or move to another profile before exporting. They stay saved in your browser until you export them, whether that's five minutes later or after several separate scrolling sessions across different visits. You can scroll a profile today, come back tomorrow and scroll further, then export everything at once.

Common questions

Does PostSnag run in the background when I'm not on Facebook?
No. PostSnag only captures posts while you're actively on a Facebook profile, Page, or group tab. Nothing runs when that tab isn't open.

What happens to posts before I click Export To Dashboard?
They're saved locally in your browser only. Nothing reaches your PostSnag account until you click Export To Dashboard.

Do I have to export every time I scroll?
No. You can scroll across multiple visits and export once, whenever you're ready. Locally captured posts stay saved until you export them.

Is capturing automatic once I open a profile?
Capturing starts as soon as posts load on the page, but PostSnag can only see what's actually on your screen. You still need to scroll for it to see more posts.

Can I capture more than one profile at the same time?
No. Capture one profile, Page, or group at a time, then move to the next and repeat the same scroll-and-export flow.
