Snapshot & Diff captures the current panel state so you can compare it to what happens next. The classic use case: snapshot on the product page, add to cart, see exactly which tags fired in response.
Taking a snapshot
- Get to a known-good state (e.g. just-loaded page, post-consent, idle stream).
- Click Snapshot in the panel header.
- The snapshot banner appears at the top of the panel.
The diff banner
Once a snapshot exists, every new fire is compared against the snapshot. New rows get a green NEW badge inline. The banner shows running counts:
SNAPSHOT @ 14:02:31
+ 4 new tags · + 12 new events · 0 violations
What's compared
| Compared | Diff shows |
|---|---|
| Tag inventory | Newly detected platforms, removed (none usually) |
| Event stream | Every event captured since the snapshot, NEW-badged |
| Cookies | Cookies set since the snapshot |
| Audit grade | Delta in score |
| Pre-consent violations | New violations since snap |
Common workflows
Verify an interaction triggers the right tag
- Snap on the product page.
- Click "Add to cart".
- Diff banner: + add_to_cart · + Meta CustomEvent.
Catch an unexpected fire
- Snap when the page is idle.
- Wait 30 seconds without doing anything.
- If the diff shows new fires, you have a tag firing on its own (timer, polling, etc.).
QA a fix
- Snap on the broken state — capture all the violations.
- Apply your fix and reload.
- Re-audit. Compare against the snapshot to confirm the violations are gone.
Clearing a snapshot
Click the × on the snapshot banner. The diff exits and NEW badges disappear.
tip
For comparison across sessions (e.g. compare today vs. last week, or pre-launch vs. post-launch), use Saved Runs — it persists across browser restarts. Snapshots are session-only.
