Local Session Sync par artinski

Stay logged in on localhost when you switch between dev, stage, UAT, and local proxy setups.

Local Session Sync copies selected cookies from your current authenticated tab to localhost, so you can test locally without repeating login flows or manually moving cookies through DevTools.

If this sounds familiar, this extension is for you:
- You log in on dev, stage, or UAT.
- You switch your local app or proxy to that environment.
- Localhost is no longer authenticated.
- You waste time digging through DevTools and manually copying cookies.

Local Session Sync removes that friction.

How it works
- Open the environment where you are already logged in.
- Click the extension and choose how to sync cookies to localhost.
- Refresh your local app.
- Continue working with the same authenticated session.

What you can do
- Copy cookies from the active tab to one or more localhost or 127.0.0.1 targets, including custom ports.
- Clear localhost cookies before syncing for a clean session.
- Sync without clearing to add or update cookies while keeping existing ones.
- Clear configured localhost cookies without copying anything.
- Filter by cookie name using substrings, comma-separated names, or /regex/.

Privacy and security
No backend, no analytics, no tracking, and no external data sharing. Source-site access is requested only when you use the extension.

Local Session Sync does not bypass authentication or authorization. It only recreates compatible cookie state on localhost for development and testing.

Stop copying cookies manually. Reuse the session you already have and get back to building.
