SESSION-TRANSPLANT / V1.0 LOCALSTORAGE × TAB-TO-TAB

Session/Transplant

One bookmarklet. Two tabs. Copy localStorage from prod, paste into local, reload. No DevTools shuffle.

Configure

Edit once, keep forever. The bookmarklet below regenerates live as you type.

Prod host contains // source tab

Local host contains // target tab

Storage

Keys // comma-separated, blank = all

Install

Show your browser's bookmarks bar (Ctrl/⌘+Shift+B), then drag the tag below onto it.

▼ DRAG THIS TO YOUR BOOKMARKS BAR ▼ Session Transplant Right-click the bookmark afterward to rename it if you want. Edit the fields above and re-drag anytime to update the installed bookmark.

Use

Open the production portal. Log in as usual. Click the Session Transplant bookmark. It reads your configured keys and copies them to the clipboard as JSON.
Switch to the local portal tab. Click the same bookmark. It reads the clipboard, previews what's about to change, and on confirm writes to storage + reloads.

First run on a new browser may prompt for clipboard permission — grant it once, you're done. Works in Chrome, Edge, Firefox, Safari on HTTPS and on localhost.
