TabSafe VerifyCapture deliberately
Only the current window is visible to the snapshot. Other work windows are never included.
Local-first Chrome extension
Know your tab backup works before you need it.
Capture only the current window, export portable JSON and readable HTML, verify integrity on import, and preview recovery before a single tab opens.
- No account or server
- No telemetry or AI
- No host permissions
Focused reliability
Not another full session manager.
Export outside Chrome
Keep a portable JSON backup plus a readable HTML copy under your control.
Verify, then restore
Schema, counts, URL safety, and SHA-256 are checked before a confirmation dialog can open tabs.
Browser-tested
Built around failure modes, not feature count.
The v0.1 acceptance run captured 20 isolated tabs, exported and independently verified both formats, rejected a tampered file, displayed restore confirmation, restored all 20 tabs, and preserved a pinned tab and named group.
The beta is free while we validate whether scheduled snapshots, diffs, and recovery drills deserve a one-time Pro version.
Private technical beta
Try it with a fresh window of nonsensitive tabs.
The test takes about 10 minutes. Because this is an unpublished build, it is intended for technical testers comfortable reviewing a ZIP and loading an unpacked extension in Developer mode.

Do not test with confidential work, finance, medical, customer, or incognito tabs. Feedback is manual and opt-in; the extension itself sends nothing.
Price validation
Would reliable automation be worth US$9 once?
No payment is being collected yet. After completing the beta, record whether you would buy a one-time Pro version with scheduled snapshots, diffs, or recovery drills.
