GR51 viewer
No file loaded

Open a .gr51 capture

Drag a file anywhere on this window, or pick a source:

Everything runs in your browser — the capture is never uploaded anywhere.

Google Drive settings

Needed only for opening files straight from Drive. Create an OAuth 2.0 Web application client and an API key in a Google Cloud project with the Drive API and Picker API enabled, and add this page's origin () to the client's authorised JavaScript origins.

Only tick that if you have configured a Drive UI integration for this deployment — see DRIVE-OPEN-WITH.md.

Load from URL

A direct link to a .gr51 (or .gr51.gz) file. The host must allow cross-origin reads. A Google Drive share link works too — it is resolved through the Drive API using your credentials.
