Questions

Are these tools free?

Yes, all of them, with no account required. The battery test asks you to authorise a read-only connection on Tesla's own login page; everything else runs entirely in your browser.

Do you store my data?

No. The calculators never send your inputs anywhere, and the VIN decoder queries NHTSA directly from your browser. The battery test reads your car once and discards the token.

Are you affiliated with Tesla?

No. This is an independent project, not affiliated with, endorsed by or connected to Tesla, Inc.
