Is Windsurf Plugin: AI Code Autocompletion on all IDEs safe?
Windsurf Plugin transmits full editor text, file paths, and browsing context to server.codeium.com on each keypress in web-based IDEs.
On supported sites such as Google Colab and similar web IDEs, the extension reads the complete text of open editor files plus the current URL, user agent, and locale, and sends this data to Codeium's servers as part of its AI autocomplete feature. Authentication is handled by passing a Firebase ID token to server.codeium.com, which returns an API key stored locally. Any website can also connect to the extension and send completion requests using the stored API key, because the manifest sets externally_connectable.matches to <all_urls>.

Where it sends data
Destinations our analysis observed Windsurf contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
