CRX Launch

A powerful utility to decompress CRX/ZIP files and run the extension code in an isolated sandboxed environment within your browser

Open CRX files easily and safely CRX Launch lets you view and test Chrome extensions (.crx files) right in your browser. You don’t need to install anything — the extension opens in a special safe window. This is useful both for developers checking their work and for everyday users who want to see what an extension does. Safety & Privacy - Runs in a separate space – The extension cannot access your browsing history, passwords, or personal information. - No installation needed – You just open the CRX file, and it runs independently from your main browser. - No tracking – We do not collect or send any data anywhere. - Everything stays on your device – Any settings or saved information remain inside your browser and never leave it. Privacy Policy We only request the permissions needed for basic functionality. Any optional permissions are asked for only with your approval. No data is ever sent to external servers — everything stays locally in your browser.
